RipEX Radio modem & Router 5 6 Getting started RipEX is a widely configurable compact radio modem, more precisely a radio IP router. All you have to do to put it into operation is to connect it to an antenna and a power supply and configure it using a PC and a web browser. Getting started Fig. 1: RipEX radio router RipEX access defaults: IP 192.168.169.169/24, username: admin, password: admin Set a static IP 192.168.169.x/24 on your PC, power on the RipEX and wait approximately 25 seconds for the RipEX OS to boot. Connect your PC to RipEXs' ETH interface, start your browser and type ht-
tps://192.168.169.169 in the address line. When accessing RipEX for the first time, you have to accept the https security certificate issued by Racom. Before attempting to do any configuration, make sure your RipEX is the only powered-up unit around. Since all units coming from factory share the same default settings ex factory, you could be accessing a different unit over the air without being aware of it. When accessing over the optional X5 USB/ETH adapter, your PC will get its IP settings from the built-
in DHCP server and you have to type https://10.9.8.7 in your browser. Remaining steps are the same and you do not need to worry about other RipEX's, you will be connected to the local unit in all cases. SCADA radio network step-by-step Building a reliable radio network for a SCADA system may not be that simple, even when you use such a versatile and easy-to-operate device as the RipEX radio modem. The following step-by-step checklist can help you to keep this process fast and efficient. 1. Design your network to ensure RF signal levels meet system requirements. 2. Calculate and estimate the network throughput and response times when loaded by your application. 3. Perform a bench-test with 3-5 sets of RipEX's and SCADA equipment (Chapter 5, Bench test). 4. Design the addressing and routing scheme of the network (Chapter 2, RipEX in detail and RipEX App notes, Address planing1) 5. Preconfigure all RipEX's (Section 5.4, Basic setup). 6. Install individual sites 1. Mount RipEX into cabinet (Section 6.1, Mounting). 1 http://www.racom.eu/eng/products/m/ripex/app/routing.html RACOM s.r.o.

RipEX Radio modem & Router 11 RipEX in detail 2. RipEX in detail 2.1. Modes of operation Radio modem RipEX is best suited for transmission of a large number of short messages where a guaranteed delivery time is required, i.e. for mission critical applications. RipEX has the following basic uses:
Polling In poll-response networks a central master unit communicates with a number of remote radiomodems one at a time. The master unit exchanges data with the currently connected remote radio, and when finished, it establishes a new connection with the next remote radio according to the polling order. Report-by-exception In report-by-exception networks remote units can be contacted similarly to polling networks. In ad-
dition, any remote unit can spontaneously send data to the master unit (typically an alarm). Mesh In mesh type networks any radio modem in the network can access any other radio modem randomly and spontaneously. Mesh network can also host polling or report-by-exception applications, even in several instances. 2.2. Bridge mode A packet received through any interface is broadcast to the appropriate interfaces of all units within the network. Packets received on COM are broadcast to both COM1 and COM2 at remote sites, allowing you to connect 2 RTU's to any radio modem. Any unit can be configured as a repeater. A repeater relays all packets it receives through the radio channel. The network implements safety mechanisms which prevent cyclic loops in the radio channel
(e.g. when a repeater receives a packet from another repeater) or duplicate packets delivered to the user interface (e.g. when RipEX receives a packet directly and then from a repeater). Beside standard packet termination by an "Idle" period on the serial port (a pause between received bytes) the bridge mode also offers "streaming". While in streaming mode, transmission on the radio channel starts immediately, without waiting for the end of the received frame on COM => zero latency. The bridge mode is suitable for all polling applications. 2.2.1. Detailed Description Bridge mode is suitable for Point-to-Multipoint networks, where Master-Slave applications with polling-
type communication protocol are used. RipEX in bridge mode is as easy to use as a simple transparent device, while providing communication reliability and spectrum efficiency by employing a sophisticated protocol in the radio channel. In bridge mode, the radio channel protocol do not solve collisions. There is a CRC check of data integrity, however, i.e. once a message is delivered, it is 100% error free. 12 RipEX Radio modem & Router RACOM s.r.o. RipEX in detail All the messages received from user interfaces (ETH&COM's) are immediately transmitted to the radio channel. ETH - The whole network of RipEX radiomodems behaves as a standard ethernet network bridge. Each ETH interface automatically learns which devices (MAC addresses) are located in the local LAN and which devices are accessible over the radio channel. Consequently, only the ethernet frames ad-
dressed to remote devices are physically transmitted on the radio channel. This arrangement saves the precious RF spectrum from extra load which would be otherwise generated by local traffic in the LAN (the LAN to which the respective ETH interface is connected). COM1,COM2 - All frames received from COM1(2) are broadcast over the radio channel and transmitted to all COM's (COM1 as well as COM2) on all radio modems within the network, the other COM on the source RipEX excluding. There is a special parameter TX delay (Adv. Config., Device), which should be used when all substations
(RTU's) reply to a broadcast query from the master station. In such case massive collisions would ensue because all substations (RTU's) would reply at nearly the same time. To prevent such collision, TX delay should be set individually in each slave RipEX. The length of responding frame, the length of radio protocol overhead, modulation rate have to be taken into account. 2.2.2. Functionality example In the following, common acronyms from SCADA systems are used:
FEP - Front End Processor, designates the communication interface equipment in the centre RTU - Remote Telemetry Unit, the terminal SCADA equipment at remote sites The single digits in illustrations are site names and do not necessarily correspond with actual addresses of both the RipEX's and SCADA equipment. Address configuration examples are given in the next chapter. Step 1 Polling cycle starts:
FEP sends a request packet for RTU3 through COM1 to the connected RipEX. Step 2 FEPs RipEX broadcasts this packet on Radio channel. RipEX3 and RipEX1 receive this packet. RipEX2 doesnt receive this packet, because it is not within radio coverage of FEPs RipEX. RACOM s.r.o. RipEX Radio modem & Router 13 RipEX in detail Step 3 RipEX3 and RipEX1 send the received packet to their COM1 and COM2. Packet is addressed to RTU3, so only RTU3 responds. RipEX1 is set as a repeater, so it retransmits the packet on Radio channel. Packet is received by all RipEXes. Step 4 RipEX2 sends repeated packet to its COM1 and COM2. RTU2 doesnt react, because the packet is addressed to RTU3. RipEX3 and FEPs RipEX do not send the repeated packet to their COM ports, because it has already been sent (RipEX3) or received (FEPs RipEX) on their COM
(anti-duplication mechanism). RTU3 sends the reply packet. Step 5 RipEX3 broadcasts the reply packet from RTU3 on Radio channel. Packet is received by RipEX1 and FEPs RipEX. Step 6 FEPs RipEX sends the packet (the reply from RTU3) to FEP through COM1. RipEX1 sends this packet to RTU1. RTU1 doesnt react, because the packet is addressed to FEP. RipEX1 repeats the packet on Radio channel. All RipEXes receive the packet. Step 7 RipEX2 sends repeated packet to its COM1 and COM2. RTU2 doesnt react, because the packet is addressed to FEP. RipEX3 and FEPs RipEXes do not send the repeated packet to their COM ports, because it has been handled already. FEP processes the reply from RTU3 and polling cycle continues 14 RipEX Radio modem & Router RACOM s.r.o. RipEX in detail 2.2.3. Configuration examples You can see an example of IP addresses of the SCADA equipment and RipEX's ETH interfaces in the picture below. In Bridge mode, the IP address of the ETH interface of RipEX is not relevant for user data communic-
ation. However it is strongly recommended to assign a unique IP address to each RipEXs' ETH interface, since it allows for easy local as well as remote service access. Moreover, leaving all RipEX's with the same (= default) IP on the ETH interface may cause serious problems, when more RipEX's are con-
nected to the samX5e LAN, even if by accident (e.g. during maintenance). Fig. 2.1: Bridge mode example Repeater Because using the bridge mode makes the network transparent, the use of repeaters has certain limit-
ations. To keep matters simple we recommend using a single repeater. However, if certain rules are observed, using multiple repeaters in the same network is possible. The total number of repeaters in the network is configured for every unit individually under Bridge mode parameters. This information is contained in every packet sent. All units that receive such packet will resume transmission only after sufficient time has been allowed for the packet to be repeated. The packets received from user ports remain buffered and are sent after the appropriate time passes. This prevents collisions between remote radio modems. There can be no repeater collisions if only one re-
peater is used. RACOM s.r.o. RipEX Radio modem & Router 15 192.168.5.51/24192.168.5.50/24192.168.5.12/24192.168.5.2/24192.168.5.3/24192.168.5.11/24192.168.5.1/24192.168.5.13/243FEP5012REPEATER RipEX in detail Where two or more repeaters are used, collisions resulting from simultaneous reception of a repeated packet must be eliminated. Collisions happen because repeaters repeat packets immediately after re-
ception, i.e. if two repeaters receive a packet from the centre, they both relay it at the same time. If there is a radiomodem which is within the range of both repeaters, it receives both repeated packets at the same time rendering them unreadable. Examples:
1. Repeaters connected serially A packet is transmitted and repeated in steps 1, 2, 3. In improperly designed networks collisions happen if a remote radio modem lies in the range of two repeaters (see the image): the packet sent from the centre (1) is received by both repeaters. It is repeated by them both (2) causing a collision at the remote. In other words there should not be more than one repeater where the centre and re-
motes' coverage areas overlap. Solution 1. Adjust signal coverage so that RPT2 is out of range of the centre and RPT1 is out of the range of the remote radio modem. This can be achieved for example by reducing the output power or using a unidirectional antenna. Solution 2. Use a single repeater.

- RipEX REM1 is within the range of two repeaters (RPT1 and RPT2). The repeaters receive a packet (1) from the centre (CEN) and repeat it at the same time (2) causing a collision at REM1. Well-designed network:
repeater
- A remote is only in the range of a single
(REM1-RPT1, REM2-RPT2). There is always only one repeater where the centre and remote cov-
erage areas overlap. 2.3. Router mode RipEX works as a standard IP router with two interfaces (radio and ethernet) and two COM port devices. There is a sophisticated anti-collision protocol on the radio channel, which checks and verifies every single packet. Being an IP router, each unit can simultaneously work as a store-and-forward repeater and deliver packets to the connected equipment. The router mode is suitable for all uses. In contrast to the bridge mode, a packet reception is confirmed over the radio channel even in very simple polling type applications, and if necessary the packet is re-
transmitted. 2.3.1. Detailed Description Router mode is suitable for multipoint networks, where multi-master applications with any combination of polling and/or spontaneous data protocols can be used. The proprietary link-layer protocol on the radio channel is very sophisticated, it can transmit both unicast and broadcast frames, it has collision avoidance capability, it uses frame acknowledgement, retransmissions and CRC checks to guarantee data delivery and integrity even under harsh interference conditions on the radio channel. RipEX works as a standard IP router with 2 independent interfaces: radio and ETH. Each interface has its own MAC address, IP address and mask. IP packets are processed according the routing table rules. You can also set the routers default gateway
(applies to both interfaces) in the routing table. The COM ports are treated as standard host devices, messages can be delivered to them as UDP datagrams to selected port numbers. The destination IP address of a COM port is either the IP of ETH or the IP of a radio interface. The source IP address of outgoing packets from COM ports is always the IP of the ETH interface.

Functionality example In the following example, there are two independent SCADA devices connected to RipEX's two COM ports. One is designated RTU (Remote Telemetry Unit) and is assumed to be polled from the centre by the FEP (Front End Processor). The other is labelled PLC (Programmable Logic Controller) and is assumed to communicate spontaneously with arbitrary chosen peer PLCs. Step 1 FEP sends a request packet for RTU1 through COM2 to its connected RipEX. Simultaneously PLC2 sends a packet for PLC1 to RipEX2 through COM1. Step 2 FEPs RipEX transmits an addressed packet for RTU1 on Radio channel. RipEX1 receives this packet, checks data integrity and transmits the acknowledgement. At the same time packet is sent to RTU1 through COM2. RipEX3 receives this packet too. It doesnt react, because this packet is directed to RipEX1 only. Step 3 RipEX2 waits till previous transaction on Radio channel is finished (anti-collision mechanism). Then RipEX2 transmits on Radio channel the addressed packet for PLC1. RipEX1 receives this packet, checks data integrity and transmits acknowledgement. At the same time packet is sent to PLC1 through COM1. Simultaneously the reply packet from RTU1 for FEP is re-
ceived on COM2. Step 4 RipEX1 transmitts the reply packet from RTU1 for FEP on Radio channel. All RipEXes receive this packet. This packet is addressed to FEPs RipEX, so only FEPs RipEX reacts. It checks data integrity and transmits the acknowledgement to RipEX1. At the same time the packet is sent to FEP through COM2. 18 RipEX Radio modem & Router RACOM s.r.o. RipEX in detail Step 5 FEP receives the response from RTU1 and polling cycle continues However any PLC or RTU can spontaneously send a packet to any destination anytime. 2.3.3. Configuration examples As it was mentioned above, RipEX radiomodem works as a standard IP router with two independent interfaces: radio and ETH. Each interface has got its own MAC address, IP address and mask. The IP router operating principles stipulate that every unit can serve as a repeater.. Everything what is needed is the proper configuration of routing tables. Radio IP addresses of the RipEXs required to communicate over the radio channel must share the same IP network. We recommend planning your IP network so that every RipEX is connected to a separate sub-network over the ethernet port. This helps to keep the routing tables clear and simple. Note Even if the IP addresses of all RipEXes in a radio channel share a single IP network, they may not be communicating directly as in a common IP network. Only the RipEXes that are within the radio range of each other can communicate directly. When communication with radio IP addresses is required, routing tables must include even the routes that are within the same network (over repeaters), which is different from common IP networks. The example configuration below does not show such routing rules for the sake of simplicity (they are not needed in most cases). RACOM s.r.o. RipEX Radio modem & Router 19 RipEX in detail Fig. 2.2: Addressing Formal consistency between the last byte of the radio IP address and the penultimate byte of the eth-
ernet address is not necessary but simplifies orientation. The Addressing image shows a routing table next to every RipEX. The routing table defines the next gateway for each IP destination. In radio transmission, the radio IP of the next radio-connected RipEX serves as the gateway. Example of a route from FEP (RipEX 50) to RTU 2:
The destination address is 192.168.2.2 The routing table of the RipEX 50 contains this record:
Destination 192.168.2.0/24 Gateway 10.10.10.1 Based on this record, all packets with addresses in the range from 192.168.2.1 to 192.168.2.254 are routed to 10.10.10.1 Because RipEX 50s radio IP is 10.10.10.50/24, the router can tell that the IP 10.10.10.1 belongs to the radio channel and sends the packet to that address over the radio channel The packet is received by RipEX 1 with the address 10.10.10.1 where it enters the router The routing table of RipEX 1 contains the record:
Destination 192.168.2.0/24 Gateway 10.10.10.2 based on which the packet is routed to 10.10.10.2 over the radio channel The packet is received by RipEX 2 The router compares the destination IP 192.168.2.2 with its own ethernet address 192.168.2.1/24 and determines that the packets destination is within its ETH network and sends the packet over the ethernet interface eventually, the packet is received by RTU 2. 20 RipEX Radio modem & Router RACOM s.r.o. 10.10.10.50/24192.168.50.2/24Routing table RipEX50:192.168.1.0/2410.10.10.1192.168.2.0/2410.10.10.1192.168.3.0/2410.10.10.3Default GW 192.168.50.2192.168.2.2/24Routing table:192.168.1.0/2410.10.10.1RipEX2192.168.50.0/2410.10.10.1192.168.3.0/2410.10.10.110.10.10.3/24192.168.3.2/24Routing table RipEX3:192.168.50.0/2410.10.10.50192.168.1.0/2410.10.10.50192.168.2.0/2410.10.10.5010.10.10.1/24192.168.1.1/24192.168.1.2/24Routing table:192.168.2.0/2410.10.10.2RipEX1192.168.50.0/2410.10.10.50192.168.3.0/2410.10.10.50192.168.3.1/24350FEP1192.168.50.1/24Radio IPETH IPFEPIP10.10.10.2/242192.168.2.1/24 RipEX in detail 2.3.4. Addressing hints In large and complex networks with numerous repeaters, individual routing tables may become long and difficult to comprehend. To keep the routing tables simple, the addressing scheme should follow the layout of the radio network. More specifically, every group of IP addresses of devices (both RipEX's and SCADA), which is accessed via a repeater, should fall in a range which can be defined by a mask and no address defined by that mask exists in different part of the network. A typical network consisting of a single centre and number of remotes has got a tree-like layout, which can be easily followed by the addressing scheme see the example in the Figure Optimised addressing below. Fig. 2.3: Optimised addressing The default gateway is also a very powerful routing tool, however be very careful whenever the default route would go to the radio interface, i.e. to the radio channel. If a packet to non-existing IP destination came to the router, it would be transmitted over the radio channel. Such packets increase the load of the network at least, cause excessive collisions, may end-up looping etc. Consequently the default route should always lead to the ETH interface, unless you are perfectly certain that a packet to non-
existing destination IP may never appear (remember you are dealing with complex software written and configured by humans). RACOM s.r.o.

Serial SCADA protocols Even when the SCADA devices are connected via serial port, communication remains secured and address-based in all directions (centre-RTU, RTU-centre, RTU-RTU). In router mode, RipEX utilises a unique implementation of various SCADA protocols (Modbus, IEC101, DNP3, Comli, RP570, C24, DF1, Profibus). In this implementation SCADA protocol addresses are mapped to RipEX addresses and individual packets are transmitted as acknowledged unicasts. Polled remote units respond to the unit that contacted them (multi master network possible) using secure packets. When needed, RTU-RTU parallel communication is also possible. 2.4.1. Detailed Description Each SCADA protocol, such as Modbus, DNP3, IEC101, DF1, etc., has its own unique message format, and more importantly, its unique way of addressing remote units. The basic task for protocol utility is to check whether a received frame is in the correct protocol format and uncorrupted. Most of the SCADA protocols use some type of error detection codes (Checksum, CRC, LRC, BCC, etc.) for data integrity control, so RipEX calculates this code and check it with the received one. RipEX radio network works in IP environment, so the basic task for the protocol interface utility is to convert SCADA serial packets to UDP datagrams. Address translation settings are used to define the destination IP address and UDP port. Then these UDP datagrams are sent to RipEX router, processed and typically forwarded as unicasts over the radio channel to their destination. If the gateway defined in the routing table belongs to the ethernet LAN, UDP datagrams are rather forwarded to the ethernet interface. After reaching the gateway (typically a RipEX router), the datagram is again forwarded ac-
cording to the routing table. Above that, RipEX is can to handle even broadcast packets from serial SCADA protocols. When broadcasts are enabled in the respective Protocol settings, the defined packets are treated as broadcast
(e.g. they are not acknowledged on Radio channel). On the Repeater station, it is possible to set whether broadcast packets shall be repeated or not. Note: UDP datagrams can be acknowledged on the radio channel (ACK parameter of router mode) but they are not acknowledged on the ethernet channel. When a UDP datagram reaches its final IP destination, it should be in a RipEX router again (either its ETH or radio interface). It is processed further according its UDP port. Either it is delivered to COM1(2) port daemon, where the datagram is decapsulated and the data received on serial interface of the source unit is forwarded to COM1(2), or the UDP port is that of a Terminal server or any other special protocol daemon on Ethernet like Modbus TCP etc. Then the datagram is processed by that daemon accordingly to the respective settings. RipEX uses a unique, sophisticated protocol on the radio channel. It guaranties data integrity even under heavy interference or weak signal conditions due to the 32 bit CRC used, minimises the likelihood of a collision and retransmits frames when collision happens, etc. These features allow for the most efficient SCADA application arrangements to be used, e.g. multi-master polling and/or spontaneous communication from remote units and/or parallel communication between remote units, etc. Note: The anti-collision protocol feature is available only in the router mode. The bridge mode is suitable for simple Master-Slave arrangements with polling-type application protocol. 22 RipEX Radio modem & Router RACOM s.r.o. RipEX in detail 2.5. Combination of IP and serial communication RipEX enables combination of IP and serial protocols within a single application. Five independent terminal servers are available in RipEX. A terminal server is a virtual substitute for devices used as serial-to-TCP(UDP) converters. It encapsulates serial protocol to TCP(UDP) and vice versa eliminating the transfer of TCP overhead over the radio channel. If the data structure of a packet is identical for IP and serial protocols, the terminal server can serve as a converter between TCP(UDP)/IP and serial protocols (RS232, RS485). RipEX also provides a built-in converter Modus RTU Modus TCP, where data structure is not the same, so one application may combine both protocols, Modus RTU and Modus TCP. 2.5.1. Detailed Description Generally, a terminal server (also referred to as serial server) enables connection of devices with a serial interface to a RipEX over the local area network (LAN). It is a virtual substitute for the devices used as serial-to-TCP(UDP) converters. Examples of the use:
A SCADA application in the centre should be connected to the radio network via serial interface, however, for some reason that serial interface is not used. The operating system (e.g. Windows) can provide a virtual serial interface to such application and converts the serial data to TCP (UDP) datagrams, which are then received by the terminal server in RipEX. This type of connection between RipEX and applic-
ation provides best results when:
There is no hardware serial interface on the computer Serial cable between RipEX and computer would be too long. E.g. the RipEX is installed very close to the antenna to reduce feed line loss. LAN already exists between the computer and the point of installation Note: The TCP (UDP) session operates only locally between RipEX and the central computer, hence it does not increase the load on the radio channel. In special cases, the terminal server can reduce network load from TCP applications . A TCP session can be terminated locally at the terminal server in RipEX, user data extracted from the TCP messages and processed as if it came from a COM port. When the data reaches the destination RipEX, it can be transferred to the RTU either via the serial interface or via TCP (UDP), using the terminal server again. Please note, that RipEX Terminal server implementation also supports the dynamical IP port change in every incoming application datagram. In such case the RipEX sends the reply to the port from which the last response has been received. This feature allows to extend the number of simultaneously opened TCP connections between the RipEX and the locally connected application up to 10 on each Terminal server. 2.6. Diagnostics & network management RipEX radiomodem offers a wide range of built-in diagnostics and network management tools. RACOM s.r.o. RipEX Radio modem & Router 23 RipEX in detail 2.6.1. Logs There are Neighbours and Statistic logs in RipEX. For both logs there is a history of 20 log files available, so the total history of saved values is 20 days (assuming the default value of 1440 min. is used as the Log save period). Neighbours The Neighbours log provides information about neighbouring units (RipEXs which can be accessed directly over the radio channel, i.e. without a repeater). Every RipEX on the network regularly broadcasts its status, the set of so called Watched values: the probability of packet loss when transmitting data over the radio channel, current supply voltage, internal temperature, measured RF output power, the Voltage Standing Wave Ratio on the antenna feed line and the total number of packets received from
/ transmitted to ETH, COM1, COM2 interfaces. In addition, the RipEX that records this data in its log also keeps track of how many times it listened to its neighbouring unit as well as of the RSS and DQ recorded. See Adv. Conf., Diagnostic for more. Statistic The Statistic log provides information about the volume of data traffic on all interfaces: radio, ETH, COM1, COM2. It offers detailed information about the number of transmitted packets, their size and the throughput per second. Moreover, a detailed division into user and service packets is available for the radio channel. See chapter Adv. Conf., Diagnostic for more. 2.6.2. Graphs An independent database periodically stores the Watched values (see 'Neighbours' log above) from up to five neighbouring RipEX's and from the local one, there including most important values from the Statistic log. All these values can be displayed as graphs. The graphs are available in summary and detailed versions. Detailed logging is triggered on when a threshold value has been reached for the specific item to enable a more detailed investigation into the units operation when an alarm event occurs. Each graph can display two different elements at once, including their set thresholds. Each of the values may originate from a different RipEX unit. See chapter Adv. Conf., Graphs for more. 2.6.3. SNMP RipEX implements an SNMP client ver. 1. The values provided by RipEX are shown in the MIB table. RipEX also allows generating SNMP traps when thresholds have been reached for the monitored values:
RSScom, DQcom, TXLost[%], Ucc, Temp, PWR, VSWR, ETH[Rx/Tx], COM1[Rx/Tx], COM2[Rx/Tx], HW Alarm Input. See chapter RipEX App notes, SNMP for RACOM RipEX1 for more. 2.6.4. Ping To diagnose the individual radio links RipEX is equipped with an enhanced Ping tool. In addition to the standard info such as the number of sent and received packets or the round trip time, it provides the 1 http://www.racom.eu/eng/products/m/ripex/app/snmp.html 24 RipEX Radio modem & Router RACOM s.r.o. overall load, the resulting throughput, BER, PER and specific data about the quality of the radio trans-

Monitoring TMonitoring is an advanced on-line diagnostic tool, which enables a detailed analysis of communication over any of the interfaces of a RipEX router. In addition to all the physical interfaces (RADIO, ETH, COM1, COM2), some internal interfaces between software modules (e.g. Terminal servers, Modus TCP server etc.) can be monitored when such advanced diagnostics is needed. Monitoring output can be viewed on-line or saved to a file in the RipEX (e.g. a remote RipEX) and downloaded later. Fig. 2.4: Monitoring See chapter Adv. Conf., Monitoring for details. 2.7. Firmware update and upgrade Certain advanced RipEX features are activated with software keys. SW feature keys enable the users to initially purchase only the functionality they require and buy additional functions as the requirements and expectations grow. Similarly, when some features (e.g. COM2) are required on certain sites, the corresponding key can be activated only where needed. Keys protect the investment into hardware. Thanks to SDR-based hardware design of RipEX no physical replacement is necessary the user simply buys a key and activates the feature. For evaluation and testing, Time-limited keys can be supplied. These keys activate the coded feature for a limited operational (power on) time only. Free Master-key trial for 30 days is in every RipEX. Software keys are always tied to a specific RipEX production code. A list of possible SW feature keys and their functionalities is given below:

Network planning The significance of planning for even a small radio network is often neglected. A typical scenario in such cases goes as follows there's not enough time (sometimes money) to do proper planning, so the network construction is started right away while decisions on antennas etc. are based mainly on budget restrictions. When the deadline comes, the network is ready but its performance does not meet the expectations. Finally the (expensive) experts are invited to fix the problem and that fix costs ten times more than a proper design process done beforehand would have. The following paragraphs are not a guide to network planning that is a topic far beyond the scope of a product manual. What is provided is the essential RipEX data needed plus some comments on common problems which should be addressed during the planning process. 3.1. Data throughput, response time A UHF radio network provides very limited bandwidth for principal reasons. Hence the first and very important step to be taken is estimating/calculating the capacity of the planned network. The goal is to meet the application bandwidth and time-related requirements. Often this step determines the layout of the network, for example when high speed is necessary, only near-LOS (Line-of-sight) radio hops can be used. RipEX offers an unprecedented range of data rates. The channel width available and signal levels ex-
pected/measured on individual hops limit the maximum rate which can be used. The data rate defines the total capacity of one radio channel in one area of coverage, which is shared by all the radio modems within the area. Then several overhead factors, which reduce the total capacity to 25-90% of the "raw"
value, have to be considered. They are e.g. RF protocol headers, FEC, channel access procedures and number of store-and-forward repeaters. There is one positive factor left an optimum compression
(e.g. IP optimization) can increase the capacity by 20-200%. All these factors are heavily influenced by the way the application loads the network. For example, a simple polling-type application results in very long alarm delivery times an event at a remote is reported only when the respective unit is polled. However the total channel capacity available can be 60-95%
of the raw value, since there are no collisions. A report-by-exception type of load yields much better application performance, yet the total channel capacity is reduced to 25-35% because of the protocol overhead needed to avoid and solve collisions. The basic calculations of network throughput and response times for different RipEX settings can be done at www.racom.eu1. Let us add one comment based on experience. Before committing to the actual network design, it is very wise to do a thorough bench-test with real application equipment and carefully monitor the load generated. A difference against the datasheets, which may be negligible in a LAN environment, may have fundamental consequences for the radio network design. To face that "small" difference when the network is about to be commissioned may be a very expensive experience. The bench test layout should include the application centre, two remotes (at least) and the use of a repeater. See the following picture for an example. 1 http://www.racom.eu/eng/products/radio-modem-ripex.html#calculation RACOM s.r.o. RipEX Radio modem & Router 27 Network planning Fig. 3.1: Application bench test 3.2. Frequency Often the frequency is simply given. If there is a choice, using the optimum frequency range can make a significant difference. Let us make a brief comparison of the most used UHF frequency bands. 160 MHz The best choice when you have to cover a hilly region and repeaters are not an option. The only fre-
quency of the set of options which can possibly make it to a distant valley, 20 km from your nearest point-of-presence, it can reach a ship 100 km from the shore base. The penalty you pay is tremendous high level of noise in urban and industry areas, omnipresent multi-path propagation, vulnerability to numerous special propagation effects in troposphere etc. Consequently this frequency band is suitable for low speeds using robust modulation techniques only, and even then a somewhat lower long-term communication reliability has to be acceptable for the application. 450 MHz The most popular of UHF frequency bands. It still can get you slightly beyond the horizon, while the signal stability is good enough for 99% (or better) level of reliability. Multi-path propagation can be a problem, hence high speeds may be limited to near-LOS conditions. Urban and industrial noise does not pose a serious threat (normally), but rather the interference caused by other transmissions is quite frequent source of disturbances. 350 MHz Put simply, character of this band is somewhere between 160 and 450 MHz. 900 MHz This band requires planning the network in microwave style. Hops longer than about 1 km have to have almost clear LOS (Line-of-sight). Of course a 25 km link can handle one high building or a 28 RipEX Radio modem & Router RACOM s.r.o. CentreRTUconfig. PCRTUdummyantenna Network planning bunch of trees in the middle, (which would be a fatal problem for e.g. an 11 GHz microwave). 900 MHz also penetrates buildings quite well, in an industrial environment full of steel and concrete it may be the best choice. The signal gets everywhere thanks to many reflections, unfortunately there is bad news attached to this - the reliability of high speed links in such environment is once again limited. Otherwise, if network capacity is your main problem, then 900 MHz allows you to build the fastest and most reliable links. The price you pay (compared to lower frequency bands) is really the price more repeaters and higher towers increase the initial cost. Long term reliable performance is the reward. The three frequency bands discussed illustrate the simple basic rules the higher the frequency, the closer to LOS the signal has to travel. That limits the distance over the Earth's surface there is no other fundamental reason why shorter wavelengths could not be used for long distance communication. On the other hand, the higher the frequency, the more reliable the radio link is. The conclusion is then very simple use the highest frequency band you can. 3.3. Signal budget For every radio hop which may be used in the network, the signal level at the respective receiver input has to be calculated and assessed against requirements. The fundamental requirements are two the data rate, which is dictated by total throughput and response times required by the application, and the availability, which is again derived from the required reliability of the application. The data rate translates to receiver sensitivity and the availability (e.g. 99,9 % percent of time) results in size of the fade margin. The basic rule of signal budget says, that the difference between the signal level at the receiver input and the guaranteed receiver sensitivity for the given data rate has to be greater than the fade margin required:
RX signal [dBm] RX sensitivity [dBm] >= Fade margin [dB]
To calculate the RX signal level, we follow the RF signal path:
Fig. 3.2: Signal path RX signal [dBm] =
+ TX output [dBm]
- TX antenna feeder loss [dB]
+TX antenna gain [dBi]
- Path loss [dB]

= -88.8 dB (10 m cable RG-58 CU, 400 MHz) dBm Received Signal Strength (RSS) The available TX output power and guaranteed RX sensitivity level for the given data rate have to be declared by the radio manufacturer. RipEX values can be found in Table 4.6, Technical parameters and Chap Section 4.4.1, Detailed Radio parameters. Antenna gains and directivity diagrams have to be supplied by the antenna manufacturer. Note that antenna gains against isotropic radiator (dBi) are used in the calculation. The figures of feeder cable loss per meter should be also known. Note that coaxial cable parameters may change considerably with time, especially when exposed to an outdoor environment. It is recommended to add a 50-100 % margin for ageing to the calculated feeder loss. 3.3.1. Path loss and fade margin The path loss is the key element in the signal budget. Not only does it form the bulk of the total loss, the time variations of path loss are the reason why a fade margin has to be added. In reality, very often the fade margin is the single technical figure which expresses the trade-off between cost and perform-
ance of the network. The decision to incorporate a particular long radio hop in a network, despite that its fade margin indicates 90 % availability at best, is sometimes dictated by the lack of investment in a higher tower or another repeater. Note that RipEXs Auto-speed feature allows the use of a lower data rate over specific hops in the network, without the need to reduce the rate and consequently the throughput in the whole network. Lower data rate means lower (= better) value of receiver sensitivity, hence the fade margin of the respective hop improves. See the respective Application note to learn more on the Auto-speed feature. When the signal path profile allows for LOS between the TX and RX antennas, the standard formula for free-space signal loss (below) gives reliable results:
Path loss [dB] = 20 * log10 (distance [km]) + 20 * log10 (frequency [MHz]) + 32.5 In the real world the path loss is always greater. UHF radio waves can penetrate obstacles (buildings, vegetation), can be reflected from flat objects, can bend over round objects, can disperse behind sharp edges there are numerous ways how a radio signal can propagate in non-LOS conditions. The addi-
tional loss when these propagation modes are involved (mostly combined) is very difficult to calculate. There are sophisticated methods used in RF design software tools which can calculate the path loss and its variations (statistical properties) over a computer model of terrain. Their accuracy is unfortunately very limited. The more obstacles on the path, the less reliable is the result. Such a tool can be very useful in the initial phase of network planning, e.g. to do the first network layout for the estimate of total throughput, however field measurements of every non-LOS radio hop should be done before the final network layout is designed. Determining the fade margin value is even more difficult. Nevertheless the software tools mentioned can give some guidance, since they can calculate the statistical properties of the signal. Generally the fade margin (for given availability) is proportional to the difference between the real path loss and the LOS path loss over the same distance. Then it is about inversely proportional to frequency (in the UHF range at least). To give an example for 10 km, non-LOS, hop on 450 MHz, fade margin of 20 dB is a bare minimum. A field test may help again, provided it is run for longer period of time (hours-days). RipEX diagnostic tools (ping) report the mean deviation of the RSS, which is a good indication of the signal stability. A multiple of the mean deviation should be added to the fade margin. 30 RipEX Radio modem & Router RACOM s.r.o. Network planning 3.4. Multipath propagation, DQ Multipath propagation is the arch-enemy of UHF data networks. The signal coming out of the receiving antenna is always a combination of multiple signals. The transmitted signal arrives via different paths, by the various non-LOS ways of propagation. Different paths have different lengths, hence the waveforms are in different phases when hitting the receiving antenna. They may add-up, they may cancel each other out. Fig. 3.3: Multipath propagation What makes things worse is that the path length changes over time. Since half the wavelength e.g. 0.3 m at 450 MHz - makes all the difference between summation and cancellation, a 0.001% change of a path length (10 cm per 10 km) is often significant. And a small change of air temperature gradient can do that. Well, that is why we have to have a proper fade margin. Now, what makes things really bad is that the path length depends also on frequency. Normally this dependency is negligible within the narrow channel. Unfortunately, because of the phase combinations of multiple waveforms, the resulting signal may get so distorted, that even the sophisticated demodulating techniques cannot read the original data. That is the situation known to RF data network engineers signal is strong enough and yet it does not work. That is why RipEX reports the, somewhat mystic, figure of DQ (Data Quality) alongside the RSS. The software demodulator uses its own metrics to assess the level of distortion of the incoming signal and produces a single number in one-byte range (0255), which is proportionate to the quality of the signal. Though it is very useful information, it has some limitations. First, it is almost impossible to determine signal quality from a single packet, especially a very short one. That results in quite a jitter of DQ values when watching individual packets. However when DQ keeps jumping up and down it indicates a serious multipath problem. In fact, when DQ stays low all the time, it must be noise or permanent interference behind the problem. The second issue arises from the wide variety of modulation and data rates RipEX supports. Though every attempt has been made to keep the DQ values modulation independent, the differences are inevitable. In other words, experience is necessary to make any conclusions from DQ reading. The less experience you have, the more data you have to collect on the examined link and use other links for comparison. The DQ value is about proportional to BER (bit error ratio) and about independent of the data rate and modulation used. Hence some rule-of-thumb values can be given. Values below 100 mean the link is unusable. For a value of 125, short packets should get through with some retransmissions, 150200 means occasional problems will exist (long term testing/evaluation of such link is recommended) and values above 200 should ensure reliable communication. RACOM s.r.o. RipEX Radio modem & Router 31 TX antenna Network planning 3.4.1. How to battle with multipath propagation?
The first step is the diagnosis. We have to realize we are in trouble and only a field measurement can tell us that. We should forget about software tools and simply assume that a multipath problem may appear on every non-LOS hop in the network. These are clear indicators of a serious multipath propagation problem:
directional antennas "do not work", e.g. a dipole placed at the right spot yields a better RSS than a long Yagi, or rotating the directional antenna shows several peaks and troughs of the signal and no clear maximum RSS changes rapidly (say 10 dB) when antenna is moved by less than a meter in any direction DQ value keeps "jumping" abnormally from frame to frame ping test displays the mean deviation of RSS greater than 6 dB Quite often all the symptoms mentioned can be observed at a site simultaneously. The typical "beginner"
mistake would be to chase the spot with the best RSS with an omnidirectional antenna and installing it there. Such a spot may work for several minutes (good luck), sometimes for several weeks (bad luck, since the network may be in full use by then). In fact, installing in such a spot guaranties that trouble will come - the peak is created by two or more signals added up, which means they will cancel out sooner or later. The right strategy is to find an arrangement where a single signal becomes dominant, possibly the most stable one. "Sweeping" a directional antenna around the place (in different heights and with dif-
ferent polarization) can tell us where the signals come from. If individual signals come from different directions, there is a good chance a long yagi can solve the problem by selecting just one of the bunch. Finding a spot where the unwanted signal is blocked by a local obstacle may help as well (e.g. installing at a side of the building instead of at the roof). Fig. 3.4: Antenna location When the multiple signals come from about the same direction, a long yagi alone would not help much. We have to move away from the location, again looking for a place where just one of the signals becomes dominant. 2050 metres may save the situation, changing the height (if possible) is often the right solution. Sometimes changing the height means going down, not up, e.g. to the base of the building or tower. We have to remember our hop has two ends, i.e. the solution may be to change antenna or its placement at the opposite end. If everything fails, it is better to use another site as a repeater. Even if such prob-
32 RipEX Radio modem & Router RACOM s.r.o. TX antennabettermultipath Network planning lematic site seems to be usable after all (e.g. it can pass commissioning tests), it will keep generating problems for ever, hence it is very prudent to do something about it as early as possible. Note: Never design hops where a directional antenna is used for a direction outside its main lobe. However economical and straightforward it may seem, it is a dangerous trap. Enigmatic cases of drop-
outs lasting couple of minutes every other day, over a clear LOS hops were created exactly like that. They look like interference which is very difficult to identify and , alas, they are caused by pure multipath propagation, a self-made one. So always use a combiner and another directional antenna if such ar-
rangement is needed. Always. Fig. 3.5: Main lobe 3.5. Network layout Certainly the network layout is mostly (sometimes completely) defined by the application. When the terrain allows for direct radio communication among all sites in the network, the designer can do neither too good nor too bad a job. Fortunately for RF network designers, the real world is seldom that simple. The conditions every single radio hop has to meet were discussed in previous paragraphs. If we are so lucky, that different layouts meeting that conditions are possible, we should exploit that for the be-
nefit of the network. The following rules should be followed when defining the layout of radio hops:
RACOM s.r.o. RipEX Radio modem & Router 33 combinercorrectlyincorrectly Network planning dominant radio sites (e.g. telco towers on hill tops) should be avoided whenever possible. Placing a single repeater which serves most part of the network from the top of a hill is a straightforward but worst alternative, which makes the whole network very vulnerable. First, a dominant site is ex-
posed to interference from a large area; second, such site is typically crowded with radio equipment of all kinds, which keeps being added, moved (also failing to work properly), so local interference may appear anytime; third, it makes the majority of communication paths dependent on a single site, so one isolated failure may stop almost the entire network. when total throughput is important, typically in report-by-exception networks, splitting the network into several independent or only slightly overlapping areas of coverage can help. The placement of repeaters which serve the respective areas is crucial. They should be isolated from each other whenever possible. Fig. 3.6: Dominant repeater Fig. 3.7: Isolated branches 34 RipEX Radio modem & Router RACOM s.r.o. MRepeaterCentreincorrectlyMCentre Network planning in report-by-exception networks the load of hops connecting the centre to major repeaters forms the bottle-neck of total network capacity. Moving these hops to another channel, or, even better, to a wire (fibre, microwave) links can multiply the throughput of the network. It saves not only the load itself, it also significantly reduces the probability of collision. More on that in the following chapter 3.6.. 3.6. Hybrid networks If an extensive area needs to be covered and multiple retranslation would be uneconomical or unsuitable, RipEXs can be interconnected via any IP network (WLAN, Internet, 3G, etc.). This is quite simple be-
cause RipEX is a standard IP router with an ethernet interface. Consequently interconnecting two or more RipEX's over a nested IP network is a standard routing issue and the concrete solution depends on that network. 3.7. Assorted practical comments Let us mention few issues, whose influence on network reliability or performance is sometimes neglected by less experienced planners:
Both vegetation and construction can grow. Especially when planning a high data rate hop which requires a near-LOS terrain profile, take into consideration the possible future growth of obstacles. When the signal passes a considerable amount of vegetation (e.g. a 100m strip of forest), think of the season. Typically the path loss imposed by vegetation increases when the foliage gets dense or wet (late spring, rainy season). Hence the fade margin should be increased if your field measure-
ments are done in a dry autumn month. The attenuation depends on the distance the signal must penetrate through the forest, and it increases with frequency. According to a CCIR, the attenuation is of the order of 0.05 dB/m at 200 MHz, 0.1 dB/m at 500 MHz, 0.2 dB/m at 1 GHz. At lower frequen-
cies, the attenuation is somewhat lower for horizontal polarization than for vertical, but the difference disappears above about 1 GHz. Though being a rare problem, moving metallic objects may cause serious disruptions, especially when they are close to one end of the radio hop. They may be cars on a highway, blades of a wind turbine, planes taking off from a nearby airport runway etc. Even when the signal is very strong, be careful when considering various cheap whips or more generally any antennas requiring a ground plane to function properly. A tempting scenario is to use the body of the metallic box, where the radio modem and connected application equipment (often a computer) is installed, as the ground plane, which leads to never-ending problems with locally RACOM s.r.o. RipEX Radio modem & Router 35 Network planning generated noise. The ground plane forms an integral part of such an antenna, hence it has to be in a safe distance (several metres) from any electronic equipment as well as the antenna itself. A metallic plate used as shielding against interference must not form a part of the antenna. Fig. 3.8: Antenna mounting Do not underestimate ageing of coaxial cables, especially at higher frequencies. Designing a 900 MHz site with 30 m long antenna cable run outdoors would certainly result in trouble two years later. We recommend to use vertical polarization for all radio modem networks. 3.8. Recommended values To check individual radio link quality run Ping test with these settings: Ping type - RSS, Length [bytes]
equal to the longest packets in the networks. Use Operating mode Bridge, when Router, ACK set to Off. Switch off all other traffic on the Radio channel used for testing. The test should run at least hours, preferrably day(s). The values below should guarantee a reliable radio link:

The USB connector also provides power supply (5 V/ 0.5 A). It can be used to temporarily power a connected device, for instance a telephone. The USB connector should not be used as permanent source of power supply. 4.2.6. Reset button RipEXs bottom-side enclosure includes a reset button accessible through an opening. When this button is pressed, the STATUS diode on the LED panel goes dark (indicating that the button has been pressed). If you hold the button for 5 seconds, the STATUS diode starts flashing slowly indicat-
ing that the reset is complete. If you continue to hold the button for 15 or more seconds (the STATUS diode starts flashing quickly) and then release it, you will reset the devices access information to default: parameters such as the login, password and ethernet IP will be reset to their defaults. Resetting access parameters to defaults also sets the Ethernet speed to Auto and results in clearing all firewall rules (which may have been blocking the access by accident). Remember to re-install your firewall if you are using one. Fig. 4.11: Reset Note To reset the RipEX only use the RESET button as described above or use the button in RipEXs web configuration, see Adv. Conf., Maintenance. Never use a power cycling (disconnecting and reconnecting power supply) to reset it. While power cycle resets, or rather reboots the RipEX, its software will not terminate correctly resulting in logs, statistics and graphs not being saved properly. 4.2.7.

Product 4.4.1. Detailed Radio parameters The very first parameter which is often required for consideration is the receiver sensitivity. Anyone interested in the wireless data transmission probably aware what this parameter means, but we should regard it simultaneously in its relation to other receiver parameters, especially blocking and desensitiz-
ation. Todays wireless communication arena tends to be overcrowded and a modern radio modem, which is demanded to compete with others in that environment, should have good dynamic range that is defined by the parameters listed above. Receiver of a radio modem, which is designed purely for optimum sensitivity, will not be able to give proper performance. However, the main receiver parameters determining its dynamic range go against each other and a clear trade-off between the sensitivity and the blocking is therefore an essential assumption. Then, from the viewpoint of a logical comparison, the consequence of better receiver sensitivity can be easily seen a lower power level of the blocking and degradation parameters generally. Blocking or desensitization values were determined according to the standards EN 300 113-2 V1.5.1, resp. EN 300 113-1 V1.7.1 (channels 25 and 12.5 kHz) and ETSI 301 166-1 V1.3.2 (channel 6.25 kHz) respectively.

Connecting the hardware Before installing a RipEX network in the field, a bench-test should be performed in the lab. The RipEX Demo case is great for this as it contains everything necessary: 3 RipEXs, Power supply, dummy load antennas, etc. If you use your own installation for lab tests, dont forget:
A dummy load or an actual antenna with 50 ohm impedance should be connected to the RipEX The minimum RF output must be set to avoid overloading the dummy antenna and to keep the re-
ceived signal at reasonable level, between -40 and -80 dBm. The power supplies must meet the requirements given in the specifications, Table 4.6, Technical parameters. Make sure the power supplies do not generate interference in the radio channel and that they can handle very fast changes in the load when RipEX switches from reception to transmis-
sion and back. Fig. 5.1: Bench test 5.2. Powering up your RipEX Switch on your power supply. LED PWR flashes quickly and after 8 seconds it switches to a green light. After approximately 30 seconds your RipEX will have booted and will be ready; the STATUS LED shines. Youll find the description of the individual LED states in Section 4.3, Indication LEDs. 5.3. Connecting RipEX to a programming PC To configure a RipEX you can connect it to your PC in two ways:

Directly over the ethernet interface Bench test Fig. 5.2: Connecting to a PC over ETH and over ETH/USB adapter 1. PC connected via ETH/USB adapter We recommend using the "X5" - external ETH/USB adapter (an optional accessory of the RipEX). The ETH/USB contains a built-in DHCP server, so if you have a DHCP client in your PC as most users, you dont need to set anything up. The RipEXs IP address for access over the ETH/USB adapter is fixed: 10.9.8.7. Go to 3. Login to RipEX 2. PC connected directly to ETH port Set a static IP address in PC, example for Windows XP:

IP address 10.9.8.7 is fixed and cannot be changed; it is independent of the IP address of the RipEXs ethernet interface.) 192.168.169.169 when connected directly to ETH Note https - For security reasons the communication between the PC and RipEX is conducted using the protocol https with ssl encryption. The https protocol requires a security cer-
tificate. You must install this certificate into your web browser (Mozilla Firefox, Internet Explorer). The first time you connect to the RipEX, your computer will ask you for au-
thorisation to import the certificate into your computer. The certificate is signed by the certification authority Racom s.r.o. It meets all security regulations and you need not be concerned about importing it into your computer. Confirm the import with all warnings and exceptions that your browser may display during installation. The login screen appears:

(All units share the same IP address and are in Bridge mode when in factory settings.) 4. IP address unknown If you dont have the adapter or you have forgotten the password, you can reset the access para-
meters to defaults, see Section 4.2.6, Reset button. RACOM s.r.o. RipEX Radio modem & Router 63 Bench test 5.4. Basic setup For the first functionality test we recommend that you use the setup wizard. The wizard will guide you through basic functionality setup. Simply select Wizard in the web interface and proceed according to the information on the screen. Repeat for all RipEXs in the test network. If you want to test applications which require a more complex setup, see Chapter 7, Advanced Config-
uration. To setup the IP addresses you can use the examples in Section 2.3.3, Configuration examples as your models, or the RipEX-App. notes, Address planing1. 5.5. Functional test To test radio communication between the RipEXs you can use the Ping test, under Diagnostic/Ping menu. Setting up and the output of this test are described in chapter Adv. Conf., Tools. If the radio communication between RipEXs is functional, you can proceed with a test of communication between the connected devices. You can monitor the status of configuration using the diodes on the LED panel, see Section 4.3, Indic-
ation LEDs. 1 http://www.racom.eu/eng/products/m/ripex/app/routing.html 64 RipEX Radio modem & Router RACOM s.r.o. 6.

Fig. 6.5: Flat mounting using Flat bracket 6.1.3. 19" rack mounting For installation into the 19" rack you can use the 19" rack shelf single or 19" rack shelf- double for one or two RipEXes. 19" rack shelf is an optional accessory delivered with/without a power supply. 66 RipEX Radio modem & Router RACOM s.r.o. Installation Fig. 6.6: Rack shelf 6.1.4. Fan kit In extreme temperatures you can install an external fan kit for additional cooling. The fan kit installs using three screws driven into the openings on the bottom side of the RipEX. Use M48 screws. Fig. 6.7: Fan kit mounting The fan kit may be controlled using the Alarm Output (Control and Power connector, Section 4.2.2, Power and Control ), which is triggered when the temperature inside RipEX exceeds a set temperature
(recommended) or it can run permanently (it should be connected in parallel to the RipEXs power supply). Configuration of the Alarm Output is described in chapter Advanced Configuration, Device. Dimensions are given in the Product chapter. RACOM s.r.o. RipEX Radio modem & Router 67 Installation Fig. 6.8: Fan kit using Alarm Output, recommended Fig. 6.9: Fan kit, always on 6.2. Antenna mounting The type of antenna best suited for the individual sites of your network depends on the layout of the network and your requirements for signal level at each site. Proper network planning, including field signal measurements, should decide antenna types in the whole network. The plan will also determine what type of mast or pole should be used, where it should be located and where the antenna should be directed to. The antenna pole or mast should be chosen with respect to antenna dimensions and weight, to ensure adequate stability. Follow the antenna manufacturers instructions during installation. The antenna should never be installed close to potential sources of interference, especially electronic devices like computers or switching power supplies. A typical example of totally wrong placement is mount a whip antenna directly on top of the box containing all the industrial equipment which is supposed to communicate via RipEX, including all power supplies. Additional safety recommendations Only qualified personnel with authorisation to work at heights are entitled to install antennas on masts, roofs and walls of buildings. Do not install the antenna in the vicinity of electrical lines. The antenna and brackets should not come into contact with electrical wiring at any time. The antenna and cables are electrical conductors. During installation electrostatic charges may build up which may lead to injury. During installation or repair work all open metal parts must be temporarily grounded. The antenna and antenna feed line must be grounded at all times. Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is covered with snow or ice. Do not touch the antenna, antenna brackets or conductors during a storm. 6.3. Antenna feed line The antenna feed line should be chosen so that its attenuation does not exceed 3 to 6 dB as a rule of thumb, see Chapter 3, Network planning. Use 50 impedance cables only. 68 RipEX Radio modem & Router RACOM s.r.o. 123456Pin No.:7SIAI-+A0+-redblack1030VDCFan Kitredblack123456Pin No.:7SIAI-+A0+-1030VDCFan Kit Installation The shorter the feed line, the better. RipEX can be installed right next to the antenna and an ethernet cable can be used to connect it to the rest of the installation and to power the RipEX . An ethernet cable can also be used for other protocols utilising the serial port, see Advanced Configuration, Terminal server. This arrangement is recommended especially when the feed line would be very long otherwise
(more than 15 meters) or the link is expected to operate with low fading margin. Always follow the installation recommendations provided by the cable manufacturer (bend radius, etc.). Use suitable connectors and install them diligently. Poorly attached connectors increase interference and can cause link instability. 6.4. Grounding To minimise the odds of the transceiver and the connected equipment receiving any damage, a safety ground (NEC Class 2 compliant) should be used, which bonds the antenna system, transceiver, power supply, and connected data equipment to a single-point ground, keeping the ground leads short. The RipEX radio modem is generally considered adequately grounded if the supplied flat mounting brackets are used to mount the radio modem to a properly grounded metal surface. If the radio modem is not mounted to a grounded surface, you should attach a safety ground wire to one of the mounting brackets or a screw on the radio modems casing. A lightning protector should be used where the antenna cable enters the building. Connect the protector to the building grounding, if possible. All grounds and cabling must comply with the applicable codes and regulations. 6.5. Connectors RipEX uses standard connectors. Use only standard counterparts to these connectors. You will find the connectors pin-outs in chapter Section 4.2, Connectors. 6.6. Power supply We do not recommend switching on the RipEXs power supply before connecting the antenna and other devices. Connecting the RTU and other devices to RipEX while powered increases the likelihood of damage due to the discharge of difference in electric potentials. RipEX may be powered from any well-filtered 10 to 30 VDC power source. The supply must be capable of providing the required input for the projected RF output. The power supply must be sufficiently stable so that voltage doesnt drop when switching from receiving to transmission, which takes less than 1.5 ms. To avoid radio channel interference, the power supply must meet all relevant EMC standards. Never install a power supply close to the antenna. Maximal supply cable length is 3 m.

Advanced Configuration This chapter is identical with the content of Helps for individual menu. 7.1. Menu header 7.1.1. Generally RipEX can be easily managed from your computer using any web browser (Mozilla Firefox, Microsoft Internet Explorer, etc.). If there is an IP connection between the computer and the respective RipEX, you can simply enter the IP address of any RipEX in the network directly in the browser address line and log in. However it is not recommended to manage an over-the-air connected RipEX in this way, because high amounts of data would have to be transferred over the Radio channel, resulting in quite long response times. When you need to manage an over-the-air connected RipEX, log-in to a RipEX, which your computer is connected to using either a cable (via LAN) or a high speed WAN (e.g. Internet). The RipEX which you are logged-in to in this way is called Local. Then you can manage any remote RipEX in the network over-the-air in a throughput-saving way: all the static data (e.g. Web page graphic objects) is downloaded from the Local RipEX and only information specific to the remote unit is transferred over the Radio channel. RipEX connected in this way is called Remote. When in Router mode, the IP address of either the Radio or Ethernet interface in the remote unit can be used for such remote management. IP routing between source (IP of ETH interface in Local RipEX) and destination IP (either Radio or ETH interface in Remote RipEX) has to exist. When in Bridge mode, IP addresses of Ethernet interfaces are used for both the Local and Remote units. Be careful, each RipEX MUST have its unique IP address and all these IP addresses have to be within the same IP network (defined by the IP Mask) when remote management is required in Bridge mode.

The Unit name in "Values from" box is changed accordingly afterwards. Disconnect When a Remote RipEX is sucessfully connected, the Disconnect button shows up. When the Disconnect process is executed, the Local RipEX (IP address in the Local box) can be managed and the Unit name in the "Values from" box changes accordingly. 7.2. Status Fig. 7.2: Menu Status 7.2.1. Device, Radio, ETH&COM's This part of Status page displays basic information about the RipEX (e.g. Serial No., MAC addreses, HW versions etc.) and overview of its most important settings. Configurable items are underlined and one click can take you to the respective Settings menu. 7.2.2. Diagnostic The current state of Watched values is displayed in the Diagnostic part of the Status page. Watched values are values of parameters, which are continuously monitored by RipEX itself. On-line help for each individual item is provided by balloon tips (when cursor is placed over an item name). When an item goes red, it means that the item is monitored for alarm and its value is in the alarm range (see Settings/Device/Alarm management) RACOM s.r.o.

Device Unit name Default = NoName Each Unit may have its unique name an alphanumeric string of up to 16 characters. Although UTF8 is supported, ASCII character has to be used on the first position in the Unit name. Following characters are not allowed:
" (Double quote)
` (Grave accent)
\ (Backslash)
$ (Dollar symbol)
; (Semicolon) Note: Unit name is solely for the user's convenience, no DNS (Domain Name Server) is used in the RipEX network. Operating Mode List box: Bridge, Router Default = Bridge 72 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Bridge Bridge mode is suitable for Point-to-Multipoint networks, where Master-Slave application with polling-
type communication protocol is used. RipEX in Bridge mode is as easy to use as a simple transparent device, while allowing for a reasonable level of communication reliability and spectrum efficiency in small to medium size networks.po In Bridge mode, the protocol on Radio channel does not have the collision avoidance capability. There is CRC check of data integrity, i.e. once a message is delivered, it is 100% error free. All the messages received from user interfaces (ETH&COM's) are immediately transmitted to Radio channel, without any checking or processing. ETH: The whole network of RipEX units behaves like a standard Ethernet network bridge, so the Eth-
ernet interface IP address itself is not significant. Each ETH interface automatically learns which devices
(MAC addresses) lie in the local LAN and which devices are accessible via the Radio channel. Con-
sequently only the Ethernet frames addressed to remote devices are physically transmitted on the Radio channel. This arrangement saves the precious RF spectrum from extra load which would otherwise be generated by local traffic in the LAN (the LAN to which the respective ETH interface is connected). COM1,COM2: all frames received from COM1(2) are broadcast over Radio channel and transmitted to all COM's (COM1 as well as COM2) on all units within the network, the other COM on the source RipEX excluding. Frame closing (COM1,2) List box: Idle, Stream Default = Idle Idle Received frames on COM1 (COM2) are closed when gap between bytes is longer than the Idle value set in COM1,2 settings and transmitted to Radio channel afterwards. Repeater List box: Off, On. Default = Off Each RipEX may work simultaneously as a Repeater (Relay) in addition to the standard Bridge operation mode.. If "On", every frame received from the Radio channel is transmitted to the respective user interface
(ETH,COM1,2) and to the Radio channel again. The Bridge functionality is not affected, i.e. only frames whose recipients belong to the local LAN are transmitted from the ETH interface. It is possible to use more than one Repeater within a network. To eliminate the risk of creating a loop, the "Number of repeaters" has to be set in all units in the network, including the Repeater units themselves. Number of repeaters [0-7]
Default = 0 If there is a repeater (or more of them) in the network, the total number of repeaters within the network MUST be set in all units in the network, including the Repeater units themselves. After transmitting to or receiving from the Radio channel, further transmission (from this RipEX) is blocked for a period calculated to prevent collision with a frame transmitted by a Repeater. Furthemore, a copy of every frame transmitted to or received from the Radio channel is stored
(for a period). Whenever a duplicate of a stored frame is received, it is discarded to avoid possible looping. These measures are not taken when the parameter "Number of repeaters" is zero, i.e. in a network without repeaters. TX delay [ms] [0-5000]
RACOM s.r.o. RipEX Radio modem & Router 73 Advanced Configuration Default = 0 It delays forwarding of all frames from user interfaces (ETH&COM's) to the Radio channel for the set time. The set value should be equal to the transmitting time of the longest message. This should be used when e.g. all sub-stations (RTU's) reply to a broadcast query from the master station. In such a case a massive collisions would take place, because all sub-stations
(RTU's) would reply more or less in the same instant. In order to prevent such a collision, TX delay should be set individually in each slave RipEX. The length of responding frame, the length of Radio protocol overhead, Modulation rate have to be taken into account. Stream In this mode, the incoming bytes from a COM are immediately broadcast over the Radio channel. COM port driver does not wait for the end of a frame. When the first byte is coming from a COM, the transmission in the Radio channel starts with the necessary frame header. If the next byte arrives before the end of transmission of the previous one, it is glued to it and the transmission on the Radio channel continues. If there is a gap between incoming bytes, the byte after the gap is treated as the first byte and the process starts again from the beginning. Padding is never transmitted between blocks of bytes. The receiving RipEX transmits incoming bytes (block of bytes) from the Radio channel to both COM ports immediately as they come. When the ETH interface is used simultaneously (e.g. for remote configuration), it works as the standard bridge described above. ETH frames have higher priority, i.e. the stream from COM is in-
terrupted by a frame from Ethernet. Stream mode is recommended to be used for time-critical application only, when the first byte has to be delivered as soon as possible. However there is not any data integrity control. If the Baud rate of COM is significantly lower than the Modulation rate on the Radio channel, frames are transmitted byte by byte. If it is higher, blocks of bytes are transmitted as frames over the Radio channel. Note: Stream mode can not be used when there is a Repeater in the network. Router Router mode is suitable for Multipoint networks, where Multi-master applications with any combination of polling and/or spontaneous data protocols can be used. The proprietary link-layer protocol on the Radio channel is very sophisticated, it can transmit both unicast and broadcast frames, it has collision avoidance capability, it uses frame acknowledgement and retransmissions and a CRC check to guar-
antee data delivery and integrity even under harsh interference conditions on the Radio channel. RipEX works as a standard IP router with 2 independent interfaces: Radio and ETH. Each interface has got its own MAC address, IP address and Mask. IP packets are processed according the Routing table. There is also possibility to set a router Default gateway (apply to both interfaces) in the Routing table. The COM ports are treated in the standard way as router devices, messages can be delivered to them as UDP datagrams to selected port numbers. Destination IP address of COM port is either the IP of ETH or the IP of Radio interfaces. The source IP address of outgoing packets from COM ports is always the IP of ETH interface. ACK List box: Off, On. 74 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Default = On On Each frame transmitted on Radio channel from this RipEX has to be acknowledged by the re-
ceiving RipEX, using the very short service packet (ACK), in order to indicate that it has received the packet successfully. If ACK is not received, RipEX will retransmit the packet according its setting of Retries. Note: The acknowledgement/retransmission scheme is an embedded part of the Radio protocol and works independently of any retries at higher protocol levels (e.g. TCP or user application protocol) There is no requirement to receive ACK from the receiving RipEX. i.e. the packet is transmitted only once and it is not repeated. Off Retries [No] [0-15]
Default = 3 When an acknowledge from the receiving RipEX is not received, the frame is retransmitted. The number of possible retries is specified. RSS threshold [-dBm] [50-150]
Default = 120 RSS (Received Signal Strength) limit for access to Radio channel. RipEX does not start transmitting when a frame is being received and the RSS is better than the set limit or when the destination MAC address of the frame is its own. Repeat COM Broadcast List box: On, Off Default = Off If On, a broadcast originated on COM port (Protocol/Broadcast = On) in any remote unit and received by this unit on Radio channel is repeated to Radio channel. Hot Standby When RipEX unit is used in RipEX-HS and Hot Standy is On there are some limitations with it. Spe-
cifically, CD pin on COM1 and HW alarm Input and Output are used internally and not available to the user. Neither Save nor Sleep modes can be activated. Please refer RipEX-HS User manual. All settings below are valid only for RipEX units in RipEX-HS equipment, where two units in Hot Standby mode are running. Both units MUST have the same settings! Only Unit names should be different as this parameter is used in SNMP to recognize the sender of SNMP traps. In order to ensure that the settings of both units are identical, it is recommended to set unit A, thereafter save its settings into a file (Maintenance/Configuration/Save to file) and use these settings for unit B. (Maintenance/Config-
uration/Restore/File path/Upload) Finally, a unique Unit name should be assigned to Unit B. List box: Off, On Default = Off When On, HW switching from RipEX unit A to RipEX unit B is performed based on the HW Alarm Output settings in Settings/Alarm management. RipEX A is the primary unit, , Unit B is activated if there is HW alarm on unit A or unit A power source is down or when Auto Toggle Period expired. When mentioned events passed, RipEX A goes to be active again. MAC Both units in RipEX-HS are using the same MAC addresses (MAC cloning). Whichever unit is active
(either A or B), RipEX Ethernet interface will use this MAC address. This MAC address has to be unconditionally set to the same value in both units used in RipEX-HS. Otherwise, the switching between units will not function properly. RACOM s.r.o. RipEX Radio modem & Router 75 Advanced Configuration Read own it is possible to download the MAC address of this unit. The value in the second unit has to be manually set to the same value then Auto Toggle mode When Auto Toggle mode is On (HW button on front panel), controller automatically switches-over to RipEX B, even if A doesn't have any alarm and uses B for a set time in order to confirm that RipEX B is fully ready-to-operate.

Time List box: Manual, NTP Default = Manual Internal calendar time of RipEX can be set manually or synchronized via NTP (Network Time Protocol). Manual RipEX internally uses the Unix epoch time (or Unix time or POSIX time) - the number of seconds that have elapsed since January 1, 1970. When RipEX calendar time is set, the Unix epoch time is calculated based on filled in values (Date, Time) and the time zone, which is set in operating system (computer), where the browser runs.

NTP 76 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Internal calendar time in RipEX is synchronized via NTP and RipEX also acts as a standard NTP server simultaneously. Current Date&Time Information about the actual date and time in RipEX Time source List box: NTP server, Internal GPS Default = NTP server NTP server The source of time is a standard NTP server. This server can be connected either via the Ethernet interface or over the Radio channel (any RipEX runs automatically as a NTP server). Internal GPS The source of time is the internal GPS. In this case only RipEX Time zone and Daylight saving parameters below are active. Source IP Default = empty IP address of the NTP server, which provides Time source. Date and Time will be requested by RipEX from there. More NTP servers can be configured, the more servers, the better time accur-
acy. If the Time source is a RipEX over Radio channel, only one source server is recommended, since the Radio channel could be overloaded. Minimum polling interval List box: 1min to 2h 17min RipEX polls the source server in order to synchronize itself in the set period or later. RipEX Time zone Select RipEX Time zone from list box. Default = (GMT +1:00) Central Europe This time zone is used for conversion of internal Unix epoch time to "human readable date&time"
in RipEX logs.. Daylight saving List box: On, Off Default = On If On, Daylight saving is activated according the respective rules for selected RipEX Time zone. RipEX NTP server Information about the status of internal NTP server in the RipEX State not synced - not synchronized synced to GPS - synchronized to internal GPS synced to NTP - synchronized to NTP server Stratum 1 to 16 (1=the best, 16=the worst, 8=when internal time in RipEX is set manually) The stratum represents the quality and accuracy of time, which the NTP server provides. Delay [ms] This is the delay of packet (1/2 round trip time), which RipEX received from the NTP server while asked for synchronization. This delay is compensated in the RipEX NTP server. Jitter [ms]
The Jitter of received times when RipEX asked for time synchronization from NTP server(s). Firewall List box: Off, On Default = Off There is a standard Linux firewall implemente. Port a range of port numbers can be entered. E.g. 2000-2120. RACOM s.r.o. RipEX Radio modem & Router 77 Advanced Configuration Connection state state-firewall active only for TCP protocol. New rrelates to the first packet when a TCP connection starts (Request from TCP client to TCP server for opening a new TCP connection). Used e.g. for allowing to open TCP only from RipEX network to outside. Established relates to an already existing TCP connection. Used e.g. for allowing to get replies for TCP connections created from RipEX network to outside. Related a connection related to the Established one. e.g. FTP typically uses 2 TCP connections control and data - where data connection is created automatically using dynamic ports. Note1: Port 443 and 8889 are used internally for service access. Exercise caution when making rules which may affect datagrams to/from this port in Firewall settings. Connection between your PC and RipEX may be lost. When this happens, use the Reset button on the bottom side of RipEX (keep it pressed for 15 sec.) in order to set Default access, which restores the default IP, default password and clears the Firewall. Note2: Firewall settings do not impact packets received and redirected from/to Radio channel. Alarm management The average values of parameters listed in the table (Watched values) are continuously monitored. When any of them exceeds the respective threshold, the selected action(s) is(are) invoked. Fig. 7.4: Menu Alarm management Note: At least 10 values have to be included on average before it is checked for the possible alarm. Since different values are sampled over different periods, different times are required to obtain correct values:
Ucc, Temp approx. 10 sec. after booting PWR, VSWR - approx. 10 sec. after booting and after the first transmission Others approx. 200 sec. of respective communication Threshold 78 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration List box: Default, Manual, Default = Default Default Default (recommended) values are set and can not be edited. Manual Thresholds can be set manually. SNMP Alarm List box: Off, On. Default = Off If On, SNMP Alarm trap is activated. The SNMP trap message is sent both when a parameter value exceeds the alarm threshold and when it returns back within its normal range. Remember to set the IP destination address for SNMP trap messages. Port number is always 162. HW Alarm Output List box: Off, N.O. (Normally Open), N.C. (Normally Closed) Default = Off If "N.O." or "N.C.", the HW Alarm Output is active and its normal status (no alarm) is open or closed, respectively. The HW Alarm Output is a pin (open n-p-n collector) on the screw terminal at the Power and Control connector on the front panel. Detail Graph start HW Alarm Input Just for information. It can be set in Settings/Graph/Detail Graph start, not here. Alarm starts Detail Graph only when this value is set to "Alarm"
List box: Off, N.O. (Normally Open), N.C. (Normally Closed) Default = Off If "N.O." or "N.C.", the HW Alarm Input is active and its normal status (no alarm) is open or closed, respectively. Alarm event is triggered when the HW Alarm Input changes its status from Normal to Alarm. Note that to Close the HW Alarm Input means connecting the respective screw terminal at the Power and Control connector on the front panel to the Ground terminal of the same connector. When Statistic and Neighbours logs are cleared, RSScom, DQcom, ETH, COM1, COM2 alarms are cleared as well. When Hot Standby is On, Alarm thresholds and HW alarm input are used internally for switching between units A and B. The HW alarm input parameter is changed to Hot Standby active. However, SNMP Alarm and Detailed Graphs tick boxes can be used for information about switching between units A and B. Power management Power supply mode List box: Always On, Save Mode, Sleep Mode Default = Always On Always On Save Mode RipEX is always on, no special power saving modes are active. RipEX is listening on Radio channel in the Save mode while consuming 2.0 W. Router mode: When the RipEX receives a packet for its IP address, it wakes up. However data from this first received packet is lost. Bridge mode: Any packet received on Radio channel wakes the unit up. Timeout List box: On, Off Default = On RACOM s.r.o. RipEX Radio modem & Router 79 Advanced Configuration When On, RipEX remains on for the set seconds from the moment of its wake-up. Timeout from wake-up [sec.]
Default = 300 [240 - 64 800]
RipEX stays on for the set time from the moment of its wake-up. Reset timeout on received packets List box: On, Off Default = Off If On, the Timeout from wake-up is reset with each packet received Sleep Mode Sleep Mode is controlled via the digital input on Power and Control connector. When the respective pin is grounded, RipEX goes to sleep and consumes only 0.1 W at 13.8 V (see Section 4.4, Technical specification). The time needed for complete wake-up is approx. 25 seconds (booting time). Timeout from sleep request [sec.]
Default = 300 [0 - 64 800]
RipEX remains on for the set time from the moment when the sleep input pin has been grounded. Neighbours&Statistics Parameters List box: Default, Manual, Default = Default Default Default (recommended) values are set and can not be edited. Manual Values can be set manually. There are 2 tables with diagnostic information in the main menu - Diagnostic/Neighbours, Diagnost-
ic/Statistic. The Neighbours table displays Watched values from RipEX and from all its neighbours.
(Neighbour = RipEX, which can be accessed directly over the radio channel, i.e. without a repeater). There is statistic information about the traffic volume in the Statistic table. Watched values broadcasting period [min]
Default = 10 min, [0 = Off]
RipEX periodically broadcasts its Watched values to neighbouring units. The Watched values can be displayed in Graphs and Neighbours menu. Note: When Bridge mode is used, watched values broadcasting creates collisions for user traffic. Be careful in using this feature. Neighbours&Statistic log save period [min]
Default = 1440 min (1 day) [10 - 7200 min]
This is the period, in which Neighbours and Statistics logs are saved in the archive and cleared and new logs start from the beginning. Note: The history files are organized in a ring buffer. Whenever a new file is opened, the numbers of files are shifted, i.e. 0->1, 1->2, etc. There is a history of 20 log files available Graphs Parameters List box: Default, Manual, Default = Default Default Default (recommended) values are set and can't be edited. Manual Values can be set manually. Graphs displays history of Watched values and history of some of the items from the Statistic table. Displayed values are stored in each RipEX including data from selected five neighbouring units. Neighbour = RipEX, which can be accessed directly over the Radio channel (not over Ethernet), 80 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration i.e. without a repeater. The graph data is stored in files, each file contains 60 samples of all values. The sampling period can be configured. There are two types of graphs- Overview and Detail. Overview graphs cover a continuous time interval back from the present, they use relatively long sampling period. Detail graph is supposed to be used in case of a special event, e.g. an alarm, and the sampling period is much shorter. Logged Neighbour IPs Default = 0.0.0.0 Up to 5 IP addresses of neighbouring units can be set. (Neighbour = RipEX, which can be ac-
cessed directly over the radio channel, i.e. without a repeater). Watched values from these units are stored in the graph files and can be displayed afterwards. Overview graph sampling period List box: 1, 2, 4, 12 hours Default = 12 hours The 60 samples per graph file result in (depending on the sampling period) 60, 120, 240 or 720 hours in each file. There are 6 files available, so total history of saved values is 15, 30, 60 or 180 days. The Overwiev graph files are organized in a ring buffer. Whenever a new file is opened, the oldest one is replaced. Detail Graph sampling period List box: 1, 5, 10, 20 mins Default = 1 min The 60 samples per graph file result in 60, 300, 600, 1200 minutes in each file. There are 20 files available. They are organized in a ring buffer. When a new file is opened, the one with oldest data is replaced. The Detail graph files may not cover a continuous segment of history. See Detail graph start for details. Detail Graph start List box: No, Alarm, Single, Continual Default = No Detail graph data sampling is started based on selected event from list box:
No Detail graph does not start. Alarm if a tickbox in Detail graph column (Settings/Alarm management) is checked, then the Detail graph file is stored in case of that alarm. Twenty samples prior the alarm event and forty samples after the alarm event are recorded. When another alarm occurs while a Detail graph file is opened, the sampling continues normally and no other file is opened. Single a single Detail graph file can be manually started. After Apply here, go to Diagnost-
ic/Graph where a Start/Stop button is available Continual Detail graph files are periodically saved in the same way as Overview graph files are. RACOM s.r.o. RipEX Radio modem & Router 81 Advanced Configuration 7.3.2. Radio Fig. 7.5: Menu Radio

List box: possible values Default = 5 W The range of values in the list box is limited to 2 W for high Modulation rates. 10 W is available only for lower Modulation rates (CPFSK) and only when the corresponding SW feature key is active. Channel spacing [kHz]**
List box: possible values Default = 25 kHz The wider the channel the higher the posible Modulation rate. Modulation rate [kbps]
Approval List box: possible values CE Modulation rate [kbps]
List box: possible values Default = 16DEQAM Radio parameters meet the requirements of ETSI EN 300 113 FCC Others Radio parameters meet the requirements of FCC part 90 CPFSK modulations have approx. 20% higher frequency deviation compared to CE, so the re-
ceiver sensitivity for the same modulation (data rate) is approx. 1-2 dB better. There are no official Radio test reports for CE 6,25 kHz and FCC 25 kHz channel spacings as yet. However Others enables setting of Modulation rates for these options. Possible values in list box are dependent on the Approval set. The two highest rates are available only when the corresponding SW feature key is active. Higher Modulation rates provide higher data speeds but they also result in poorer receiver sensitivity, i.e. reduced coverage range. Reliability of communication over a radio channel is always higher with lower Modulation rates. FEC List box: possible values Default = Off FEC (Forward Error Correction) is a very effective method to minimize radio channel impairments. Basically the sender inserts some redundant data into its messages. This redundancy allows the re-
ceiver to detect and correct errors (to some extent). The improvement comes at the expense of the user data rate. The lower the FEC ratio, the better the capability of error correction and the lower the user data rate. The User data rate = Modulation rate x FEC ratio. Optimization*
List box: On, Off Default = Off RACOM s.r.o. RipEX Radio modem & Router 83 Advanced Configuration Optimization is applicable in Router mode for packets directed to Radio channel. It watches packets on individual radio links and optimizes both the traffic to the counterpart of a link and the sharing of the Radio channel capacity among the links. On an individual link the optimizer supervises the traffic and it tries to join short packets when oppor-
tunity comes. However in case of heavy load on one link (e.g. FTP download) it splits the continuous stream of packets and creates a window for the other links. To minimize the actual load, Zlib compression
(with LZ77 decimation and Huffman coding) and other sophisticated methods are used. In addition a special TCP optimiser is used for TCP/IP connections. It supervises every TCP session and eliminates redundant packets. It also compresses TCP headers in a very efficient way. The overall effect of the Optimization depends on many factors (data content, packet lengths, network layout etc.), the total increase of network throughput can be anything from 0 to 200%, or even more in special cases. Note: Apart from this Optimization, there is an independent compression on the Radio channel, which works in both Operating modes, Bridge and Router. This compression is always On. Encryption AES 256 (Advanced Encryption Standard) can be used to protect your data from an intrusion on Radio channel. When AES 256 is On, control block of 16 Bytes length is attached to each frame on Radio channel. AES requires an encryption key. The length of key is 256 bits (32 Bytes, 64 hexa chars). The same key must be stored in all units within the network. List box: Off, AES 256 Default = Off When AES 256 Key mode List box: Pass Phrase, Manual Default = Pass Phrase Pass phrase It is not necessary to fill in 32 Bytes of hexa chars in order to set the encryption key. The key can be automatically generated based on a Pass phrase. Fill in your Pass phrase (any printable ASCII character, min. 1 char., max. 128 char.). The same Pass phrase must be set in all units within the network Manual The key can be configured manually (fill in 32 Bytes of 64 hexa chars) or it can be randomly generated using Generate button. The same key must be in all units within the network, i.e. it has to be gener-
ated only in one unit and copied to the others. MTU [bytes]*
Default = 1500 Bytes [70 - 1500] (max. packet size) When a packet to be transmitted from the Radio interface is longer than the MTU (Maximum Transmis-
sion Unit) set, the RipEX router performs standard IP fragmentation. A packet longer than the configured size is split into the needed number of fragments, which are then independently transmitted - the first packet(s) is (are) transmitted fragment-size long, the last packet contains the remaining bytes. The reassembly of the fragments into the original packet normally takes place in the unit at the end of the path. Reducing the maximum length of a frame on a Radio link may improve its performance under unfavour-
able conditions (interference, multi-path propagation effects). However the recommended place to determine the packet size is the actual user interface, e.g. a COM port. Note that the IP fragmenting is possible in the Router mode only. 84 RipEX Radio modem & Router RACOM s.r.o. 7.3.3. ETH

It can be set only in the Routing menu while Router mode. DHCP*
List box: Off, Server Default = Off Server DHCP (Dynamic Host Configuration Protocol) Server in RipEX sets network configuration (IP address, Mask, Gateway) in connected DHCP clients. They have to be connected to the same LAN as the ETH interface of RipEX. The Mask set is the same as on RipEX ETH, the Gateway is the IP address of ETH interface of RipEX. Typical DHCP client is e.g. a PC used for configuration of RipEX. Important! Never activate the DHCP Server when ETH interface of RipEX is connected to LAN, where another DHCP server is operating. Start IP Default = IP address of ETH interface + 1 DHCP Server assigns addresses to connected clients starting from this address. RACOM s.r.o.

Default = 1 day (max. 10 days) A DHCP Client has to ask DHCP Server for refresh of the received configuration within this timeout, otherwise the Lease expires and the same settings can be assigned to another device (MAC). Assigned IP's Preferred IP's Table shows MAC addresses of Clients and IP addresses assigned to them by the Server. Expiration is the remaining time till the respective Lease expires. If the assigned IP addresses are required to be deleted, set DHCP Server to Off, then action Apply and set DHCP server to On (+Apply) again. It is possible to define which IP should be assigned by the Server to a specific MAC. The requested IP has to be within the Start IP End IP range. Shaping*
List box: On, Off Default = Off Ethernet interface could easily overload the Radio channel. Because of that, it is possible to shape traffic received from the ETH interface. If On, specified volume of Data [Bytes] in specified Period [sec] is allowed to enter the RipEX from ETH interface. The first packet which exceeds the limit is stored in the buffer and transmitted when new Period starts. Further over-limit packets are discarded.

TCP socket in RipEX is kept active after the receipt of data for the set number of seconds. Broadcast**
List box: On, Off Default = Off Some Master SCADA units send broadcast messages to all Slave units. SCADA application typically uses a specific address for such messages. RipEX (Protocol utility) converts such message to an IP broadcast and broadcasts it to all RipEX units resp. to all SCADA units within the network. If On, the address for broadcast packets in SCADA protocol has to be defined:
Broadcast address format - List box Hex, Dec - format in which broadcast address is defined. Broadcast address - address in the defined format (Hex, Dec) Address translation List box: Table, Mask Default = Mask In a SCADA protocol, each SCADA unit has a unique address, a "Protocol address". In RipEX Radio network, each SCADA unit is represented by an IP address (typically that of ETH interface) and a UDP port (that of the protocol daemon or the COM port server to which the SCADA device is con-
nected via serial interface). A translation between "Protocol address" and the IP address & UDP port pair has to be done. It can be done either via Table or via Mask. Each SCADA message received from serial interface is encapsulated into a UDP/IP datagram, where destination IP address and destination UDP port are defined according the settings of Address translation. Mask Translation using Mask is simpler to set, however it has some limitations:
all IP addresses used have to be within the same network, which is defined by this Mask the same UDP port is used for all the SCADA units, which results in the following limitations:
SCADA devices on all sites have to be connected to the same interface (COM1 or COM2) only one SCADA device to one COM port can be connected, even if the RS485 interface is used Base IP Mask Default = IP address of ETH interface When the IP destination address of the UDP datagram, in which serial SCADA message received from COM1(2) is encapsulated, is created, this Base IP is taken as the basis and only the part defined by Mask is replaced by 'Protocol address'. Default = 255.255.255.0 A part of Base IP address defined by this Mask is replaced by 'Protocol address'. The SCADA protocol address is typically 1 Byte, so Mask 255.255.255.0 is most frequently used. UDP port (Interface) List box: COM1, COM2, TS1-TS5, TCPM1, Manual. Default = COM1 This UDP port is used as the destination UDP port in the UDP datagram in which serial SCADA packet received from COM1(2) is encapsulated. Default UDP ports for COM1, COM2 or Terminal servers 1-5 (TS1-TS5) or Modbus TCP (TCPM1) can be used or UDP port can be set manually. If the destination IP address belongs to a RipEX and the UDP port is not RACOM s.r.o. RipEX Radio modem & Router 87 Advanced Configuration Table assigned to COM1(2) or to a Terminal server or to any special daemon running in the destin-
ation RipEX, the packet is discarded. The Address translation is defined in a table. There are no limitations like when the Mask translation is used. If there are more SCADA units on RS485 interface, their Protocol addresses translate to the same IP address and UDP port pair. There are 3 possibilities how to fill in aline in the table:
One "Protocol address" to one "IP address" (e.g.: 56 > 192.168.20.20) Interval of "Protocol addresses" to one "IP address" (e.g.: 56-62 > 192.168.20.20) Interval of "Protocol addresses" to interval of "IP addresses" (e.g.: 56-62 > 192.168.20.20-
26). It is possible to write only the start IP and dash, the system will add the end address itself. Protocol address This is the address which is used by SCADA protocol. It may be set either in Hexadecimal or Decimal format according the List box value. Protocol address length can be 1 Byte, only for DNP3 and UNI protocols 2 Bytes. IP address to which Protocol address will be translated. This IP address is used as destination IP address in UDP datagram in which serial SCADA packet received from COM1(2) is en-
capsulated. UDP port (Interface) This is the UDP port number which is used as destination UDP port in UDP datagram in which the serial SCADA message, received from COM1(2), is encapsulated. You may add a note to each address up to 16 characters long for your convenience. (E.g. Remote unit #1" etc.). You may tick/untick each translation line in order to make it active/not active. Edit Delete Add buttons allow to edit or to add or to delete a line. The lines can be sorted using up and down arrows. IP Note Active Modify Terminal servers Generally a Terminal Server (also referred to as a Serial Server) enables connection of devices with serial interface to a RipEX over the local area network (LAN). It is a virtual substitute for devices used as serial-to-TCP(UDP) converters. Examples of the use:
A SCADA application in the centre should be connected to the Radio network via a serial interface, however for some reason that serial interface is not used. The operating system (e.g. Windows) can provide a virtual serial interface to such application and converts the serial data to TCP (UDP) datagrams, which are then received by the Terminal server in RipEX. This type of interconnection between RipEX and application is especially advantageous when:
there is not any physical serial interface on the computer the serial cable between the RipEX and computer would be too long (e.g. the RipEX is installed very close to the antenna to improve radio coverage). the LAN between the computer and the place of RipEX installation already exists Modbus TCP is used with local TCP sessions on slave sites or when combination of Modbus RTU and Modbus TCP is used. For more information refer to Application note Modbus TCP/RTU2 This applies also to other SCADA protocol TCP versions, e.g. DNP3 TCP. 2 http://www.racom.eu/eng/products/m/ripex/app/modbus.html 88 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Note: The TCP (UDP) session operates only locally between the RipEX and the central computer, hence it does not increase the load on Radio channel. In some special cases, the Terminal server can be also used for reducing the network load from applic-
ations using TCP. A TCP session can be terminated locally at the Terminal server in RipEX, user data extracted from TCP messages and processed like it comes from a COM port. When data reaches the destination RipEX, it can be transferred to the RTU either via a serial interface or via TCP (UDP), using the Terminal server again. Terminal server List box: On, Off Default = Off If On, up to 5 independent Terminal servers can be set up. Each one can be either of TCP or UDP Type, Keepalive is the timeout in sec for which the TCP socket in RipEX is kept active after the last data reception or transmission, My IP address of a Terminal server has to be always the same as the IP address of the RipEX ETH interface, My Port can be set as required. Destination IP and Destination port values belong to the locally connected application (e.g. a virtual serial interface). In some cases, applications dynamically change the IP port with each datagram. In such a case set Destination port=0. RipEX will then send replies to the port from which the last response was received. This feature allows to extend the number of simultaneously opened TCP connections between a RipEX and locally connected application to any value up to 10 on each Terminal server. Protocol follows the same principles as a protocol on COM interface. You may tick/untick each in-
dividual Terminal server in order to make it active/inactive. 7.3.4. COM's
* Active only when Router mode The COM ports in RipEX are served by special daemons, which are connected to the IP network through a standard Linux socket. Consequently a COM port can be accessed using any of the two IP addresses
(either ETH or Radio interface) used in a RipEX and the respective UDP port number. The source IP address of outgoing packets from COM ports is equal to IP address of the interface (either Radio or Ethernet) through which the packet has been sent. Outgoing interface is determined in Routing table according to the destination IP. The default UDP port numbers are COM1 = 8881, COM2 = 8882. If necessary they may be changed using CLI, nevertheless it is recommended to stick to the default values because of dependencies between different settings (e.g. Protocols) in the network. Note: UDP port settings is valid only in Router mode. In Bridge mode all packets received by COM port are broadcasted to all COM ports on all RipEXes within the network. RACOM s.r.o. RipEX Radio modem & Router 89 Advanced Configuration Fig. 7.7: Menu COM Type List box: possible values Default = RS232 COM1 is always RS232, COM2 can be configured to either RS232 or RS485. Note: The settings of Data rate, Data bits, Parity and Stop bits of COM port and connected device must match. Baud rate [bps]
List box: standard series of rates from 300 to 115200 bps Default = 19200 Select Baud rate from the list box: 300 to 115200 bps rates are available. Serial ports use two-level (binary) signaling, so the data rate in bits per second is equal to the symbol rate in bauds Data bits List box: 8, 7 Default = 8 The number of data bits in each character. Parity List box: None, Odd, Even Default = None Wikipedia: Parity is a method of detecting errors in transmission. When parity is used with a serial port, an extra data bit is sent with each data character, arranged so that the number of 1-bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted. However, an even number of errors can pass the parity check. Stop bits List box: possible values Default = 1 90 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Wikipedia: Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Idle [bytes]
Default = 5 [0 - 2000]
This parameter defines the maximum gap (in bytes) in the received data stream. If the gap exceeds the value set, the link is considered idle, the received frame is closed and forwarded to the network. MRU [bytes]
Default = 1600 [1 - 1600]
MRU (Maximum Reception Unit) an incoming frame is closed at this size even if the stream of bytes continues. Consequently, a permanent data stream coming to a COM results in a sequence of MRU-
sized frames sent over the network. Note 1: very long frames (>800 bytes) require good signal conditions on the Radio channel and the probability of a collision increases rapidly with the length of the frames. Hence if your application can work with smaller MTU, it is recommended to use values in 200 400 bytes range. Note 2: this MRU and the MTU in Radio settings are independent. However MTU should be greater or equal to MRU. Flow control List box: None, RTS/CTS Default = None RTS/CTS (Request To Send / Clear To Send) hardware flow control (handshake) between the DTE
(Data Terminal Equipment) and RipEX (DCE - Data Communications Equipment) can be enabled in order to pause and resume the transmission of data. If RX buffer of RipEX is full, the CTS goes down. Note: RTS/CTS Flow control requires a 5-wire connection to the COM port. Protocol*
List box: possible values Default = None Each SCADA protocol used on serial interface is more or less unique. The COM port daemon performs conversion to standard UDP datagrams used in RipEX Radio network. Each protocol has its individual configuration parameters, which are described in separate Help page (accessible from configuration light box Protocol - click on Protocol, then on Help). Protocol None simply discards any data received by the COM port or from the network, which means that the respective COM port is virtually disconnected from the RipEX. RACOM s.r.o. RipEX Radio modem & Router 91 Advanced Configuration 7.3.5. Protocols Fig. 7.8: Menu Protocols COM Generally Each SCADA protocol like Modbus, DNP3, IEC101, DF1 etc. has its unique message format, most importantly its unique way of addresing of remote units. The basic task for protocol utility is to check whether received frame is within protocol format and it is not corrupted. Most of the SCADA protocols are using some type of Error Detection Codes (Checksum, CRC, LRC, BCC, etc.) for data integrity control, so RipEX calculates this code and check it with the received one. RipEX radio network works in IP enviroment, so the basic task for Protocol interface utility is to convert SCADA serial packets to UDP datagrams. The Address translation settings are used to define the destination IP address and UDP port. Then these UDP datagrams are sent to RipEX router, processed there and they are typically forwarded as unicasts to Radio channel to their destination. When the gateway defined in the Routing table belongs to the Ethernet LAN, UDP datagrams are rather forwarded to the Ethernet interface. After reaching the gateway (typically a RipEX router again), the datagram is forwarded according to the Routing table. Note: Even if UDP datagrams, they can be acknowledged on the Radio channel (ACK parameter of Router mode), however they are not acknowledged on Ethernet. When the UDP datagram reaches its final IP destination, it should be in a RipEX router again (either its ETH or Radio interface). It is processed further according its UDP port. It can be delivered to COM1(2) port daemon, where the datagram is decapsulated and the data received on the serial interface of the source unit are forwarded to COM1(2). The UDP port can also be that of a Terminal server or any other special protocol daemon on Ethernet like Modbus TCP etc. The datagram is then processed ac-
cordingly to the respective settings. RipEX uses a unique, sophisticated protocol on Radio channel. This protocol ensures high probability of data delivery. It also guarantees data integrity even under heavy interference or weak signal conditions due to the 32 bit CRC used, minimises the probability of collision and retransmits frame when a collision happens, etc., etc. These features allow for the most efficient SCADA application arrangements to be 92 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration used, e.g. multi-master polling and/or spontaneous communication from remote units and/or parallel communication between remote units etc. Note: These Radio protocol features are available only in the Router mode. The Bridge mode is suitable for simple Master-Slave arrangement with a polling-type application protocol. Common parameters The parameters described in this section are typical for most protocols. There is only a link to them in description of the respective Protocol. Mode of Connected device List box: Master, Slave Default = Master Typical SCADA application follows Master-Slave scheme, where the structure of the message is different for Master and Slave SCADA units. Because of that it is necessary to set which type of SCADA unit is connected to the RipEX. Note: For SCADA Master set Master, for SCADA Slave set Slave. Master defined. SCADA Master always sends addressed messages to Slaves. The way of addressing is different from SCADA protocol to SCADA protocol, so this is one of the main reasons why an individual Protocol utility in RipEX for each SCADA protocol has to be used. Broadcast List box: On, Off Default = Off Some Master SCADA units sends broadcast messages to all Slave units. SCADA application typically uses a specific address for such messages. RipEX (Protocol utility) converts such message to an IP broadcast and broadcasts it to all RipEX units resp. to all SCADA units within the network. If On, the address for broadcast packets in SCADA protocol has to be defined:
Broadcast address format - List box Hex, Dec - format in which broadcast address is Broadcast address - address in the defined format (Hex, Dec) Address translation List box: Table, Mask Default = Mask In a SCADA protocol, each SCADA unit has a unique address, a "Protocol address". In RipEX Radio network, each SCADA unit is represented by an IP address (typically that of ETH interface) and a UDP port (that of the protocol daemon or the COM port server to which the SCADA device is connected via serial interface). A translation between "Protocol address" and the IP address & UDP port pair has to be done. It can be done either via Table or via Mask. So SCADA message received from serial interface is encapsulated into a UDP/IP datagram, where destination IP address and destination UDP port are defined according the settings of Address translation. Mask Translation using Mask is simpler to set, however it has some limitations:
all IP addresses used have to be within the same network, which is defined by this Mask the same UDP port is used for all the SCADA units, which results in the following limitations:
SCADA devices on all sites have to be connected to the same interface (COM1 or COM2) RACOM s.r.o. RipEX Radio modem & Router 93 Advanced Configuration Table only one SCADA device to one COM port can be connected, even if the RS485 interface is used Base IP Mask Default = IP address of ETH interface When the IP destination address of UDP datagram, in which serial SCADA message re-
ceived from COM1(2) is encapsulated, is created, this Base IP is taken as the basis and only the part defined by Mask is replaced by 'Protocol address'. Default = 255.255.255.0 A part of Base IP address defined by this Mask is replaced by 'Protocol address'. The SCADA protocol address is typically 1 Byte, so Mask 255.255.255.0 is most frequently used. UDP port (Interface) List box: COM1,COM2, TS1-TS5, TCPM1, Manual. This UDP port is used as the destination UDP port in UDP datagram in which serial SCADA packet received from COM1(2) is encapsulated. Default UDP ports for COM1, COM2 or Terminal servers 1-5 (TS1-TS5) or Modbus TCP (TCPM1) can be used or UDP port can be set manually. If the destination IP address belongs to a RipEX and the UDP port is not assigned to COM1(2) or to a Terminal server or to any special daemon running in the destination RipEX, the packet is discarded. The Address translation is defined in a table. There are no limitations such as when the Mask translation is used. If there are more SCADA units on RS485 interface, their Protocol ad-
dresses should be translated to the same IP address and UDP port pair, where the multiple SCADA units are connected. There are 3 possibilities how to fill in the line in the table:
One "Protocol address" to one "IP address" (e.g.: 56 > 192.168.20.20) Interval of "Protocol addresses" to one "IP address" (e.g.: 56-62 > 192.168.20.20) Interval of "Protocol addresses" to interval of "IP addresses" (e.g.: 56-62 > 192.168.20.20-
26). It is possible to write only the start IP and dash, the system will add the end address itself. Protocol address This is the address which is used by SCADA protocol. It may be set either in Hexadecimal or Decimal format according the List box value. Protocol address length can be only 1 Byte. IP IP address to which Protocol address will be translated. This IP address is used as des-
tination IP address in UDP datagram in which serial SCADA packet received from COM1(2) is encapsulated. UDP port (Interface) This is UDP port number which is used as destination UDP port in UDP datagram in which the serial SCADA message, received from COM1(2), is encapsulated. You may add a note to each address up to 16 characters long for your convenience. (E.g. Remote unit #1 etc.). You may tick/un-tick each translation line in order to make it active/not active. Edit Delete Add buttons allow to edit or to add or to delete a line. The lines can be sorted using up and down arrows. Note Active Modify Slave SCADA Slave typically only responds to Master requests, however in some SCADA protocols it can communicate spontaneously. 94 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Messages from serial interface are processed in similar way as at Master site, i.e. they are encap-
sulated in UDP datagrams, processed by router inside the RipEX and forwarded to the respective interface, typically to Radio channel. Broadcast accept List box: On, Off Default = On If On, broadcast messages from the Master SCADA device to all Slave units are accepted and sent to connected Slave SCADA unit. Protocols implemented:
None All received frames from COM port are discarded. Async link Async link creates asynchronous link between two COM ports on different RipEX units. Received frames from COM1(2) are sent without any processing transparently to Radio channel to set IP destin-
ation and UDP port. Received frames from Radio channel are sent to COM1 or COM2 according UDP port settings. Parameters Destination IP UDP port (Interface) This is IP address of destination RipEX, either ETH or Radio interface. This is UDP port number which is used as destination UDP port in UDP datagram in which packet received from COM1(2) is encapsulated. C24 C24 is a serial polling-type communication protocol used in Master-Slave applications. When a RipEX radio network runs in the Router mode, multiple C24 Masters can be used within one Radio network and one Slave can be polled by more than one Master. Underlined parameters are described in Common parameters. Mode of Connected device Master Address translation Table Mask Slave Protocol frames List box: 1C,2C,3C,4C Default = 1C One of the possible C24 Protocol frames can be selected. Frames format RACOM s.r.o. RipEX Radio modem & Router 95 Advanced Configuration List box: Format1,Format2,Format3,Format4,Format5 Default = Format1 One of the possible C24 Frames formats can be selected. According to the C24 protocol specification, it is possible to set Frames formats 1-4 for Protocol frames 1C-3C and formats 1-5 for 4C. Note: The RipEX accepts only the set Protocol frames and Frames format combination. All other combinations frames are discarded by the RipEX and not passed to the application. Local ACK List box: Off, On Default = Off Available for Protocol frame 1C only. When On, ACK on COM1(2) is send locally from this unit, not over the Radio channel. Cactus Cactus is a serial polling-type communication protocol used in Master-Slave applications. When a RipEX radio network runs in the Router mode, multiple Cactus Masters can be used within one Radio network and one Slave can be polled by more than one Master. Underlined parameters are described in Common parameters. Mode of Connected device Master Broadcast Note: There is not the possibility to set Broadcast address, since Cactus broadcast messages always have the address 0x00. Hence when the Broadcast is On, packets with this destination are handled as broadcasts. Address translation Table Mask Slave Broadcast accept Max gap timeout [ms]
Default = 30 The longest time gap for which a frame can be interrupted and still received successfully as one frame. It should not be set below 10ms, while 1540 ms should be OK for a typical Cactus protocol device. Comli Comli is a serial polling-type communication protocol used by Master-Slave application. When RipEX radio network run in Router mode, more Comli Masters can be used within one Radio network and one Slave can be polled by more Masters. Broadcasts packets are not used, so the configuration is using only some parameters described Common parameters. Mode of Connected device 96 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Master Address translation Table Mask Slave DF1 Only the full duplex mode of DF1 is supported. Each frame in the Allen-Bradley DF1 protocol contains the source and destination addresses in its header, so there is no difference between Master and Slave in the Full duplex mode in terms of RipEX configuration. Block control mode List box: BCC, CRC Default = BCC According to the DF1 specification, either BCC or CRC for Block control mode (data integrity) can be used. Broadcast According to the DF1 specification, packets for the destination address 0xFF are considered broadcasts. Hence when Broadcast is On, packets with this destination are handled as broadcasts. Address translation Table Mask Advanced parameters ACK Locally List box: Off, On Default = On If "On", ACK frames (0x1006)are not transferred over-the-air. When the RipEX receives a data frame from the connected device, it generates the ACK frame
(0x1006) locally. When the RipEX receives the data frame from the Radio channel, it sends the frame to the connected device and waits for the ACK. If the ACK is not received within 1 sec. timeout, RipEX sends ENQ (0x1005). ENQ and ACK are not generated for broadcast packets. DNP3 Each frame in the DNP3 protocol contains the source and destination addresses in its header, so there is no difference between Master and Slave in terms of the RipEX configuration. The DNP3 allows both Master-Slave polling as well as spontaneous communication from remote units. Broadcast - Note: There is not the option to set the Broadcast address, since DNP3 broadcast messages always have addresses in the range 0xFFFD - 0xFFFF. Hence when Broadcast is On, packets with these destinations are handled as broadcasts. Address translation Table Mask RACOM s.r.o.

When RipEX radio network run in Router mode, more IEC 870-5-101 Masters can be used within one Radio network and one Slave can be polled by more Masters. IEC 870-5-101 protocol configuration is using all parameters described in Common parameters. Mode of Connected device Master Broadcast - only On, Off. Protocol broadcast address is not configurable, it is defined by Address mode in Advance parameter (default 0xFF) Address translation Table Mask Slave Broadcast accept Advanced parameters Address mode Even if IEC 870-5-101 is the standard, there are some users which customized this standard according their needs. When addressed byte has been moved, RipEX has to read it on the correct location. IEC101 Address byte location according to IEC 870-5-101 standard. Broadcast from Master station is generated when address byte is 0xFF. 2B ADDR TELEGYR SINAUT Two byte address (IEC 870-5-101 standard is 1 Byte). The frame is 1 Byte longer than standard one. There is Intel sequence of bytes: low byte, high byte. Mask Address translation has to be used, because Table one is limited just to one byte address length. Broadcast from Master station is generated when low address byte is 0xFF and high address byte is 0x00. The Control byte in standard IEC packet is omitted. The frame is 1 Byte shorter than standard one. This is typically used in Telegyr 805/809 protocol. Broadcast from Master station is generated when address byte is 0x00. The sequence of Address byte and Control byte in the frame is changed-over. Broadcast from Master station is generated when address byte is 0x00. ITT Flygt ITT Flygt is a serial polling-type communication protocol used in Master-Slave applications. ITT Flygt protocol configuration uses all parameters described in Common parameters. Mode of Connected device Master Broadcast 98 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Note: There is not a possibility to set the Broadcast address, since ITT Flygt broadcast messages always have the address 0xFFFF. Hence when the Broadcast is On, packets with this destination are handled as broad-
casts. First Slave Address Default = 1 Slave addresses are not defined in the ITT Flygt protocol. However Slave addresses have to be defined in the RipEX network. This is the First Slave address in decimal format. Number of Slaves Default = 1 Since the ITT Flygt protocol Master (centre) polls the Slaves (remotes) one by one without any addressing, number of slaves has to be defined. Address translation Table Mask Slave Broadcast accept Wait timeout [ms]
Default = 5000 An ITT Flygt Slave sometimes sends the WAIT COMMAND (0x13) to its Master. The RipEX does not accept the next WAIT COMMAND (discards it), till the Wait timeout does not expire. The Re-
commended value is in the 1-10 seconds range. Modbus Modbus RTU is a serial polling-type communication protocol used by Master-Slave application. When RipEX radio network run in Router mode, more Modbus Masters can be used within one Radio network and one Slave can be polled by more Masters.

RipEX Radio modem & Router 99 Advanced Configuration Mode of Connected device Master Broadcast Address translation Table Mask Slave Broadcast accept RP570 RP570 is a serial polling-type communication protocol used in Master-Slave applications. When a RipEX radio network runs in the Router mode, multiple RP570 Masters can be used within one Radio network and one Slave can be polled by more than one Master. Underlined parameters are described in Common parameters. Mode device of Connected Master Local simulation RB List box: Off, On Default = Off The RP570 protocol Master very often transmits the RB packets (hold packets) solely to check whether slaves are connected. In order to minimize the Radio channel load, the RipEX can be configured to respond to these packets locally and not to transmit them to the slaves over the Radio channel. If On, the RipEX responds to RB packets received from the RP 570 master locally over the COM interface. However from time to time (RB period) the RB packets are transferred over the network in order to check whether the respective slave is still on. When the RB response from the slave to this RB packet is not received over the Radio channel within the set RB timeout, i.e. the respective slave is out of order, the central RipEX stops local answering to RB packets from the master for the respective slave. RB Net period [s]
Default = 10 The RipEX responds to the RB packets locally and in the set RB period the RB packets are trans-
ferred over the network. RB Net timeout [s]
Default = 10 (maximum=8190) Whenever an RB packet is sent over the network, the set RB Net timeout starts. When the RB re-
sponse from the remote unit (slave) is not received within the timeout, i.e. the respective slave is out of order, the central RipEX stops the local answering to RB packets from the master for the re-
spective slave. Address translation 100 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Table Mask Slave Slave Local simulation RB List box: Off, On Default = Off The RP570 Slave expects to receive RB packets from the Master. When the Local simulation RB on the Master is On, the RB packets are transferred over the Radio channel only in the RB Net period (see Master settings). The Local simulation RB has to be set the same (On or Off) on all sites in the network, i.e. on the master as well as all slaves. If On, the RipEX generates RB packets locally and transmits them over the COM interface in the RB Request period and expects the RB response for each RB packet from the RP570 Slave within the RB Response timeout. When the RipEX does not receive the response(s) from the RP570 slave, the RipEX does not respond to the RB packet from the Master which it receives over the Radio channel. RB Request period [ms]
Default = 200 (maximum=8190) RipEX sends locally RB packets to the connected RTU in the set period. RB Response timeout [ms]
Default = 500 (maximum=8190) The RipEX expects a response to the RB packet within the set timeout. If it is not received, the RipEX does not respond to RB packets from the Master received over the Radio channel. RTU address (Hex) Default = 01 Active only when the Local simulation RB is On. The connected RTUs address is supposed to be filled in. This address (0x00-0xFF) is used in the RB packets generated locally in the RipEX and transmitted over the COM. UNI UNI is the "Universal" protocol utility designed by RACOM. It is supposed to be used when the applic-
ation protocol is not in the RipEX list and the addressed mode of communication is preferable in the network (which is a typical scenario). The key condition is that messages generated by the Master application device always contain the respective Slave address and that address (or its relevant part) position, relative to the beginning of the message (packet, frame), is always the same (Address position). Generally two communication modes are typical for UNI protocol: In the first one, communication has to be always initiated by the Master and only one response to a request is supported; in the second mode, Master-Master communication or combination of UNI protocol with ASYNC LINK protocol and spontaneous packets generation on remote sites are possible. The UNI protocol is fully transparent, i.e. all messages are transported and delivered in full, without any modifications. Underlined parameters are described in Common parameters. RACOM s.r.o. RipEX Radio modem & Router 101 Advanced Configuration Mode of Connected device Master Address mode List box: Binary (1 B), ASCII (2 B), Binary (2B LSB first). Binary (2B MSB first). Default = Binary (1 B) RipEX reads the Protocol address in the format and length set (in Bytes). The ASCII 2-Byte format is read as 2-character hexadecimal represent-
ation of one-byte value. E.g. ASCII characters AB are read as 0xAB hex (10101011 binary, 171 decimal) value. Address position Specify the sequence number of the byte, where the Protocol address starts. Note that the first byte in the packet has the sequence number 1, not 0. Address mask (Hex) When the Address mode is Binary 2 Bytes, a 16-bit value is read from the SCADA protocol message according to the Address mode setting
(either the MSB or the LSB first), The resulting value is then bit-masked by the Address mask and used as the input value for SCADA to IP ad-
dress translation (e.g. by a table). The default value of the Address mask is FFFF, hence the full 16-bit value is used by default. Example:
The Address mode is set to Binary (2B LSB first), the Address mask is set to 7FF0 and the Address position is set to 2. The SCADA message starts with bytes (in hex) 02 DA 92 C3 .. The 2-Byte address is read as 0x92DA (note the LSB came first in the message), Then 0x7FF0 mask is applied and the resulting value 0x12D0 (0x92DA & 0x7FF0) is used as the input for the translation. Poll response control List box: On, Off Default = On On The Master accepts only one response per a request and it must come from the the specific remote to which the request has been sent. All other packets are discarded. This applies to the Master - Slave communication scheme. Note: It may happen, that a response from a slave (No.1) is delivered after the respective timeout expired and the Master generates the re-
quest for the next slave (No.2) in the meantime. In such case the delayed response from No.1 would have been considered as the response from No.2. When Poll response control is On, the delayed response from the slave No.1 is discarded and the Master stays ready for the response from No.2. Off The Master does not check packets incoming from the RF channel
- all packets are passed to the application, including broadcasts . That allows E.g. spontaneous packets to be generated at remote sites. This mode is suitable for Master-Master communication scheme or a com-
bination of the UNI and ASYNC LINK protocols. 102 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Broadcast Address translation Table Mask Slave Broadcast accept RACOM s.r.o. RipEX Radio modem & Router 103 Advanced Configuration 7.4. Routing Routing table is active only when Router mode (Settings/Device/Operating mode) is set. In such a case RipEX works as a standard IP router with 2 independent interfaces: Radio and ETH. Each interface has its own MAC address, IP address and Mask. IP packets are then processed according the Routing table. The COM ports are treated in the standard way as router devices, messages can be delivered to them as UDP datagrams to selected UDP port numbers. Destination IP address of COM port is either IP of ETH or IP of Radio interfaces. The source IP address of outgoing packets from COM ports is equal to IP address of interface (either Radio or Ethernet) through packet has been sent. Outgoing interface is determined in Routing table according the destination IP. The IP addressing scheme can be chosen arbitrarily, only 127.0.0.0/8 and 192.0.2.233/30 restriction applies. 7.4.1. Menu Routing Fig. 7.9: Menu Routing Interfaces Radio IP address and Mask define the IP network (Radio LAN) within RipEX can communicate directly over the Radio channel, however the radio repeater (defined as the gateway in the route) can be used. All units which are supposed to communicate directly have to be within the same Radio LAN. ETH IP address and Mask define the IP network (LAN) in which RipEX can communicate directly over the Ethernet. All devices which should be accessible directly have to be within the same LAN. Routes Destination, Mask, Gateway Each IP packet, received by RipEX through any interface (Radio, ETH, COM1 or COM2), has got a destination IP address. RipEX (router) forwards the received packet either directly to the destination IP address or to the respective Gateway, according to the Routing table. Any Gateway has to be within 104 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration the network defined by IP and Mask of one of the interfaces (Radio, ETH), otherwise the packet is discarded. Each line in the routing table defines a Gateway (the route, the next hop) for the network (group of addresses) defined by Destination IP and Mask. When the Gateway for the respective destination IP address is not found in the Routing table, the packet is forwarded to the Default gateway. When Default gateway is not defined (0.0.0.0), the packet is discarded. The network (Destination and Mask) can by specified in both formats. Either 10.11.12.13/24 in Destin-
ation or 10.11.12.13 in Destination and 255.255.255.0. in Mask columns. RipEX displays and converts both formats. There is also a balloon tip while the cursor is in the specific line on the Mask. It shows which IP addresses are included in the network which is routed to the respective Gateway. Interface It may happen that networks defined by IP and Mask of router interfaces overlap. In such a case it is necessary to define to which interface (Radio, ETH) the packet should be forwarded. When Auto is selected, the packet is forwarded automatically to the correct interface. Note You may add a note to each route with your comments up to 16 characters (only ASCII is supported) for your convenience. (E.g. Central station etc.). Following characters are not allowed:
" (Double quote)
` (Grave accent)
\ (Backslash)

Neighbours and Statistic Fig. 7.10: Menu Neighbours Neighbours and Statistics follow the same pattern. Most importantly, they share a common time frame. One Log save period and one Difference log (pair of Clear and Display buttons) apply to both logs. For both logs there is a history of 20 log files available, so the total history of saved values is 20 days
(assuming the default value of 1440 min. is used as Log save period). The files are organized in a ring buffer. Whenever a new file is opened or the Operating mode is changed, the numbers of files are shifted, i.e. 0->1, 1->2, etc. Then both the Neighbours and the Statistic log values are accumulated and weight-averaged over the whole Log save period (one day by default). Hence a fresh change in a traffic pattern is not completely averaged out when the recent log is e.g. 23 hours long. When a fresh and shorter sample of the log values is needed, there is a Difference log available. It uses an independent buffer for data and can be cleared and displayed anytime. Buttons All buttons are common for both logs, Neighbours and Statistic:
Save button the log is manually saved, stored in the history file and cleared. This equals to situation when the Log save period expires. When the Operating mode (Bridge / Router) is changed, the log is also Saved. Note: Remember that both the Neighbours and Statistic logs are saved. Difference Clear button when pressed, the Difference log is cleared. The standard Neighbour and Statistic logs are not touched. Similarly, when the Log save period expires and the Neighbour and Statistic logs are cleared, the values in Difference log are not touched. Note: Remember that both Neighbours and Statistic logs are cleared. Display button displays values of the Difference log, i.e. the values accumulated from time when the Set button has been pressed. 106 RipEX Radio modem & Router RACOM s.r.o. History Top bar menu.

For actual values click the Refresh button. Last update Log uptime Log Save period The difference between Log start and Last update. It redirects to Settings/Device/Neighbours&Statistics where Statistic&Neighbours log save period can be set. Also the Watched values broadcasting period can be set there. This is a period in which RipEX periodically broadcasts its Watched values to neighbouring units, where they are saved and can be displayed in the Neighbours table. Neighbours Neighbours log provides information about neighbouring units (Neighbour = RipEX, which can be ac-
cessed directly over the radio channel, i.e. without a repeater). Protocol on Radio channel uses MAC addresses. A unit can learn the IP address of its neighbour only when it receives its broadcast of Watched values (it contains both MAC and IP addresses). Thus when Watched values broadcasting is Off in a Neighbour (Settings/Device/Neighbours&Statistics), there is MAC address on the respective line in the Neighbours table. When a known IP adress of a Neighbour changes, the unit cumulates data to the old IP address till it receives the next Watched values broadcast. Maximum number of Neighbours listed in the table is 100. If this number is exceeded, the least signi-
ficant Neighbour is omitted. The first criterion is whether this RipEX communicates with the Neighbour and the second criterion is the RSS level. Neighbours Table Generally:
there are balloon tips with on line help for column names the table can be sorted (descending/ascending) by any column, by clicking the column name two values are displayed for each item: Last and Average. Last is the last value received, the Average is a running average over all values received since the start of the log. The values received more recently weigh up to 50% more in the average than the earlier ones. if a value in the table is underlined, it is a link to Graphs green background indicates, that the item is monitored for alarm and its average value is within the normal range (Settings/Device/Alarm management) RACOM s.r.o.

These N/A Ucc, Temp, PWR, VSWR are refreshed every 1s. The other values in both, Neighbours and Statistics values are not displayed in Graphs tables are refreshed every 20s IP addresses:
Bridge mode Router mode Due to broadcast pattern of traffic in Radio channel, all frames generated by user application(s) cumulate in one line in the Neighbour table. When diagnostic or service frames (e.g. Watched values) are transmitted in the network, they are listed in separate lines, distinguished by IP ad-
dress of their respective Ethernet interfaces. MAC addresses of Radio interface are used for link layer communication on Radio channel. When RipEX knows the IP address corresponding with the MAC address (the IP has been the destination IP of a packet transferred), IP address is displayed. If the IP address is not known, the MAC address is displayed. The first three columns are logged by the receiving RipEX itself. Received headers [Count]
Total number of frame headers received from the respective RipEX. RSS [dBm]
Received Signal Strength. DQ Data Quality of received frames. The DQ value is about proportional to BER (bit error ratio) and about independent of the data rate and modulation used. Consequently when data rate is lowered, the DQ value increases and the other way round. Judging the DQ values requires experience, rule-of-thumb figures are as followsvalues: DQ below 100 means the link is unusable, aroundt 125 short packets starthould getting through, about 160 and above can be considered good values.

Tools Ping Fig. 7.13: Menu Ping Ping (Packet InterNet Groper) is a utility used to test the reachability of a particular host on an IP network. It operates by sending echo request packets to the target host and waiting for an echo response. In the process it measures the rtt (round trip time - the time from transmission to reception) and records any packet loss. The source IP address of Ping in RipEX is always the IP address of Radio interface (Settings/ETH/IP) While using Ping, be sure that correct routing between source and destination IP addresses exists. Also pinged device has to have ICMP echo response enabled. RipEX has the ICMP echo response always enabled. Note: Ping utility generates on-line report each 2 seconds while you are connected to Local unit and each 10 sec. while it is generated from Remote unit and it is transffered over Radio channel.

There is RSS (Received Signal Strenght) and DQ (Data Quality) information from the radio hop with lowest RSS, separately for both directions (To and From the destination RipEX). The mdev values for both the RSS and DQ are provided, giving idea on signal homogeneity. The lower values are recorded, the more reliable the link should be. The Homogenity shows the jitter of RSS values from individual pings.

In addition to all the physical interfaces (RADIO, ETH, COM1, COM2), some internal interfaces between software modules can be monitored when such ad-
vanced diagnostics is needed. Monitoring output can be viewed on-line or saved to a file in the RipEX (e.g. a remote RipEX) and downloaded later. Description of internal interfaces can be found below. Interfaces Tick boxes:

When the selected File period expires or the File size has been reached, whichever event occurs first, the file is closed and left waiting to be downloaded later. The start and stop of monitoring to file is independent of the on-line monitoring, i.e. the monitoring output is recorded even when the on-line monitoring is stopped. Buttons Buttons located at the bottom of the monitoring screen come in two groups:
left: Start, Stop, Clear buttons, which control the on-line monitoring, and right: File Start, File Stop, File Status, Download buttons, which control the recording into the file. The two processes can be started/stopped by the respective buttons independently any time. Only one of the Start/Stop (File Start/File Stop) button pair is accessible at a time, depending on the status of the respective monitoring process (the other button is gray). The Clear button clears the screen with on-line monitoring output, even when the monitoring is running at the moment. The File Status button refreshes the status of the file which is stored in RipEX and of the recording process. It is recommended to use this button whenever you can not be sure whether your browser is synchronized with the server in the RipEX. The Download button invokes the Download File dialog. Whenever the Start or File Start button is activated, the current settings of the monitoring from your web page are applied. When you change any setting on the page, both Start and File Start buttons indicate that a change has been made. They turn red when the respective monitoring process is idle and they change into Apply button when the monitoring is running, i.e. when the respective 118 RipEX Radio modem & Router RACOM s.r.o. Advanced Configuration Start (File Start) button has been gray. Clicking the Apply button enforces the configuration change
(e.g. adding one more interface) to the running monitoring process Internal interfaces description Internal interfaces are the interfaces between a SW module and the central router module. All these interfaces can be located in Fig. 1 below:
Fig. 7.15: Monitoring The central router and bridge module acts as a standard IP router or bridge, i.e. decides to which interface an IP packet goes next. The COM ports module does the conversion from messages re-
ceived over the serial ports to UDP datagrams and vice-versa. The Radio channel module wraps
(unwraps) IP packets into radio channel frames and handles all sorts of service frames. Terminal servers process messages from/to virtual COM ports, transforming them into/from the same UDP datagrams as the COM port module does. The Modbus TCP server similarly processes packets of Modbus TCP(RTU) protocol - see the relevant application note (Modbus TCP/RTU) for details. Since it is possible to monitor the messages from virtual COM and the resulting UDP datagrams independently, the TSn and the Modbus TCP have two internal interfaces distinguished as (com) and (router).

On the right side one may see the list of available keys and their respective status values. Possible status values are:
Not present Active Active (timeout dd:hh:mm:ss) the key can be time limited. For such a key, the remaining time of activity is displayed (1d 07:33:20). Time of activity of a key is counted only when the unit is switched on. Time limited key can be put on hold, i.e. temporarily deactivated. Press the correspond-
ing Hold button (possibly several Hold buttons for several selected keys) and then press the Apply button to put the selected key(s) on hold. On hold (timeout dd:hh:mm:ss) the key is On hold, i.e. temporarily not active. To re-activatete such a key, press the Activate and then Apply buttons. Master when Master key (unlocks all keys) is active. Master (On hold) The time-limited key for a specific feature is On hold, however the feature is active because of the Master key. Fill in the key you have received from RACOM or your distributor. Upload when pressed, the selected SW key is uploaded into the RipEX, however it is not yet active. You can subsequently upload more keys. Apply when pressed, all the uploaded keys are activated and/or status values of Time limited keys are changed following their respective buttons Activate or Hold have been pressed. Afterwards the unit automatically reboots itself. 120 RipEX Radio modem & Router RACOM s.r.o. 7.6.2.

Fill in the file path, or browse your disk in order to find the file. When a file is selected, it can be uploaded. Upload uploads configuration from the selected file and activates it. The unit reboots itself afterwards. 7.6.3. Firmware Fig. 7.18: Menu Maintenance Firmware The firmware in the unit consists of several parts, however they come in one firmware package
(file_name.cpio). Individual part names and their versions can be seen. There can be two versions of firmware packages stored within the unit Active and Archive. Unit is always using the Active version. The Archive version is there just for convenience and safety of firmware manipulations. It can also be uploaded to a remote unit over the Radio channel. Upload to Archive Fill in the file path, or browse your disk in order to find the file. When a file is selected and the Upload to Archive button pressed, it is uploaded and becomes the Archive firm-
ware. RACOM s.r.o. RipEX Radio modem & Router 121 Advanced Configuration Note it is recommended to do this only over reliable Ethernet connections and not over the Radio channel. Archive to Active when pressed, the Active firmware is substituted by the Archive firmware. Either All or only Only the different versions are replaced according to the Versions list box setting. The unit reboots itself afterwards. Copy Archive to Other unit he Archive firmware package can be copied to another unit typically over Radio channel. Fill in the IP address of the desired unit and press the button. Note If possible, copy FW only over one Radio hop where radio link is quality sufficiently high. Otherwise it can be very time consuming. When Router mode is used, dont forget to set correct Routing tables settings. 7.6.4. Password Fig. 7.19: Menu Maintenance Password It is highly recommended to change default password (admin) even if the user name remains always the same (admin). When the Apply button is pressed, the unit reboots. 7.6.5. Miscellaneous Reboot when pressed, the unit correctly shuts down and starts again (performs the cold start which equals to a power cycle). The reboot time is approx. 25 sec. 7.6.6. Technical support package Fig. 7.20: Menu Maintenance Configuration Technical support package is the file where some internal events are recorded. It can be used by RACOM technical support when a deeper diagnostic is required. The most recent part of it can be downloaded to the local PC. Log depth List box: possible values Default = 500 This is the number of rows downloaded. The greater the number of rows, the longer the history to be found in the file. However more lines means greater file size as well. When downloaded from a remote unit over Radio channel in poor signal conditions, a lower Log depth should be selected. 122 RipEX Radio modem & Router RACOM s.r.o. CLI Configuration 8. CLI Configuration CLI interface (Command Line Interface) is an alternative to web access. You can work with the CLI interface in text mode using an appropriate client, either ssh (putty) or telnet. CLI login and password are the same as those for web access via browser. Access using ssh keys is also possible. Keys are unique for each individual RipEX Serial number. Private key is downloaded in RipEX, for public key kindly contact RACOM and provide RipEX S/N. Connecting with a putty client. Type the following command into the window Host Name (or IP address):
admin@192.168.169.169 Press Open. Then enter the password admin. Thu Mar 31 10:56:47 CEST 2011 Welcome to RipEX Command Line Interface (CLI) on station: RipEX 50 For help try: cli_help CLI(admin):~$
The cli_help command shows a list of all available functions. The commands can be completed using the Tab key. If you select the command with the left mouse button, you can copy it to the clipboard and then use the right mouse button to insert it into the location of the cursor. You can use the -t parameter to send commands to remote RipEXs. Every command gives a comprehensive help when invoked with -h or help parameter. An example of a parameter request for the COM1 port of the RipEX with IP 192.168.1.1:
CLI(admin):~$ cli_cnf_show_com 1 -t 192.168.1.1 COM UDP port setting: Default (d) COM UDP port (manual): 50001 COM link type: RS232 (RS232) COM bitrate: 19200 (19200) COM data bits: 8 (8) COM parity: None (n) COM stop bits: 1 (1) COM idle size: 5 chars COM MTU: 1600 bytes COM handshake: None (n) COM break length: 1000 chars COM protocol: None (n) The CLI is a powerful tool for advanced management of RipEX, especially suited for automated tasks. It is best learned through its own help system, hence it is not described in further detail here. RACOM s.r.o. RipEX Radio modem & Router 123 Troubleshooting 9. Troubleshooting 1. I dont know what my RipEXs IP is how do I connect?
Use the "X5" external ETH/USB adapter and a PC as a DHCP client. Type 10.9.8.7 into your browsers location field. Alternatively, you can reset your RipEX to default access by pressing the Reset button for a long time, see Section 4.2.6, Reset button
. Afterwards, you can use the IP 192.168.169.169/24 to connect to the RipEX. Note that, in addition to resseting access parameters to defaults, your firewall rules will be cleared as well. 2. My PC is unable to connect to the RipEX. In PC settings, Network protocol (TCP/IP)/Properties, the following configuration is sometimes used:
General tab - Automatically receive address from a DHCP server Alternate configuration tab - User defined configuration, e.g. 192.168.169.250 Use this configuration instead:
General tab - Use the following IP, e.g. 192.168.169.250 Verify your PCs IP address from the command line:
Start/Run/command ipconfig Send a ping to the RipEX:
ping 192.168.169.169 If the ping runs successfully, look for a problem with the browser configuration. Sometimes the browser may need minutes to make new connection. Im configuring the RipEX in its default state but its not working. There is another RipEX with the default configuration in close vicinity. Switch it off. I have configured one RipEX in its default state. But I cannot connect to another. 3. 4. Your PC keeps a table of IP addresses and their associated MAC addresses. You can view it from the command line:
Start/Run/command arp -a IP address 192.168.169.169 physical address 00-02-a9-00-fe-2c dynamic type All RipEXs share the default IP address but their MAC addresses are different, meaning this record interferes with your purpose. The timeout for automatic cache clearing may be longer so you can delete the entry manually by typing:
124 RipEX Radio modem & Router RACOM s.r.o. Troubleshooting arp -d 192.168.169.169 or delete the entire table by typing:
arp -d *
Then you can ping the newly connected RipEX again. I have assigned the RipEX a new IP address and my PC lost connection to it. Change the PCs IP address so that it is on the same subnet as the RipEX. I entered the Router mode and lost connection to the other RipEXs. 5. 6. Enter correct data into the routing tables in all RipEXs. 7. The RSS Ping test shows low RSS for the required speed. Use higher output, a unidirectional antenna, better direct the antenna, use a better feed line, taller pole. If nothing helps, lower the speed. 8. The RSS Ping test reports good RSS but low DQ. When the DQ value is much lower then it should be at the given RSS, typicaly it is a case of multi-path propagation. It can cause serious problems to data communication, especially when high data rates are used. Since the interfering signals come from different directions, changing the direction of the antenna may solve the problem. A unidirectional antenna should be used in the first place. Metallic objects in close vicinity of the antenna may cause harmful reflections, relocating the antenna by few meters may help. Change of polarization at both ends of the link could be the solution as well. 9. The RSS Ping test shows bad homogeneity. Quite often the bad homogeneity comes together with a low DQ. In that case follow the advice given in the previous paragraph. If the DQ does correspond to the RSS level, you should look for unstable elements along the signal route a poorly installed antenna or cable, moving obstacles (e.g. cars in front of the antenna), shifting reflective areas etc. If you cannot remove the cause of disturbances, you will need to ensure signal is strong enough to cope with it. RACOM s.r.o. RipEX Radio modem & Router 125 Safety, environment, licensing 10. Safety, environment, licensing 10.1. Frequency The radio modem must be operated only in accordance with the valid frequency license issued by na-
tional frequency authority and all radio parametres have to be set exactly as listed. Important Use of frequencies between 406.0 and 406.1 MHz is worldwide-allocated only for Interna-
tional Satellite Search and Rescue System. These frequencies are used for distress beacons and are incessantly monitored by the ground and satellite Cospas-Sarsat system. Other use of these frequencies is forbidden. 10.2. Safety distance Safety distances with respect to the US health limits of the electromagnetic field intensity are in Minimum Safety Distance tables below, calculated for different antennas and RipEX power levels. The distances were calculated according to (doplnit normu) and apply to far-field region only. Whenever the result is comparable or smaller than the ac-
tual size of the respective antenna, the field intensity is even smaller than the far-field based calculation and the safety limit is never exceeded. For output power 0.2 W or lower the safety limit is not exceeded at any distance and any of the antennas. The minimal safe distance is typically ensured by the antenna position on a mast. When special install-
ation is required, the conditions of the standard EN 50385: 2002 have to be met. The distance between the persons and antenna shown in the table bellow comply with all applicable standards for human exposure of general public to RF electromagnetic fields.
