Compliance General The Aprisa SR digital radio predominantly operates within frequency bands that require a site license be issued by the radio regulatory authority with jurisdiction over the territory in which the equipment is being operated. It is the responsibility of the user, before operating the equipment, to ensure that where required the appropriate license has been granted and all conditions attendant to that license have been met. Changes or modifications not approved by the party responsible for compliance could void the users authority to operate the equipment. Equipment authorizations sought by 4RF are based on the Aprisa SR radio equipment being installed at a fixed restricted access location and operated in point-to-multipoint or point-to-point mode within the environmental profile defined by EN 300 019, Class 3.4. Operation outside these criteria may invalidate the authorizations and / or license conditions. The term Radio with reference to the Aprisa SR User Manual, is a generic term for one end station of a point-to-multipoint Aprisa SR network and does not confer any rights to connect to any public network or to operate the equipment within any territory.

About the Radio The 4RF Aprisa SR Radio The 4RF Aprisa SR is a point-to-multipoint digital radio providing secure narrowband wireless data connectivity for SCADA, infrastructure and telemetry applications. The radios carry a combination of serial data and Ethernet data between the base station, repeater stations and remote stations. A single Aprisa SR is configurable as a point-to-multipoint base station, a remote station or a repeater station. Aprisa SR User Manual 18 | About the Radio Product Overview Network Coverage and Capacity In a simple point-to-multipoint network, an Aprisa SR, configured as a base station, will communicate with multiple remote units in a given coverage area. With a link range of up to 60 km, a typical deployment will have 30 150 remote stations operating to the base station. However, geographic features, such as hills, mountains, trees and foliage, or other path obstructions, such as buildings, tend to limit radio coverage. Additionally, geography may reduce network capacity at the edge of the network where errors may occur and require retransmission. However, the Aprisa SR uses Forward Error Correction (FEC) which greatly improves the sensitivity performance of the radio resulting in less retries and minimal reduction in capacity. Ultimately, the overall performance of any specific network will be defined by a range of factors including the geographic location, the number of remote stations in the base station coverage area and the traffic profile across the network. Effective network design will distribute the total number of remote stations across the available base stations to ensure optimal geographic coverage and network capacity. The following are the maximum number of remotes that can operate to a base station for the product configuration:

Configuration Maximum Number Of Remotes Non Protected Base Station Protected Base Station 500 150 Remote Messaging On start-up, the remote station transmits a registration message to the base stations which responds with a registration response. This allows the base station to record the details of all the remote stations active in the network. If a remote station cannot register with the base station after multiple attempts (RF LED flashing red) within 10 minutes, it will automatically reboot. If a remote station has registered with the base station but then loses communication, it will automatically reboot within 6 minutes. There are two message types in the Aprisa SR network, broadcast messages and unicast messages. Broadcast messages are transmitted by the base station to the remote stations and unicast messages are transmitted by the remote station to the base station. All remotes within the coverage area will receive broadcast messages and pass them on to either the Ethernet or serial interface. The RTU determines if the message is intended for it and will accept it or discard it. Only the base station can receive the unicast messages transmitted from the remote station. Unicast messages are ignored by other remote stations which may be able to receive them. Aprisa SR User Manual About the Radio | 19 Repeater Messaging The Aprisa SR uses a routed protocol throughout the network whereby messages contain source and destination addresses. Upon registration, the radios populate an internal neighbor table to identify the radios in the network. The remote stations will register with a base station, or a repeater, and the repeater registers with a base station. In networks with a repeater, the repeater must register with the base station before the remotes can register with the repeater. Additionally, all messages contain a message type field in the header and messages are designated as either a broadcast message, originating from a base station, or a unicast message, originating from a remote station. In a network with a repeater, or multiple repeaters, the base station broadcasts a message which contains a message type, a source address and a destination address. The repeater receives the message and recognizes it is a broadcast message, from the message type and source address and re-broadcasts the message across the network. All remote stations in the coverage area will receive the message but only the radio with the destination address will act upon the message. Similarly, the remote station will send a unicast message which contains a message type (unicast) a source address and a destination address (the base station). The repeater will receive this message; recognize the message type and source address and forward it to the destination address. It is this methodology which prevents repeater-repeater loops. If there is repeater (A) which, in some circumstances, is able to pick up the RF signal from another repeater (B), it will not forward the message as it will only forward broadcast messages from the base station (recognized by the source address). For unicast messages the repeater (A) will recognize that the message (from repeater (B)) is not from a remote with which it has an association and similarly ignore the message.

These three layers are required to transport data across the wireless channel in the Point-to-Multipoint (PMP) configuration. The Aprisa SR DLL is largely based on the 802.15.4 MAC layer using a proprietary implementation. Physical Layer The Aprisa SR PHY uses a one or two frequency duplex transmission mode which eliminates the need for a duplexer. However, a Dual Antenna port option is available for separate transmit and receive antenna connection to support external duplexers or filters (half duplex operation). Remote nodes are predominantly in receive mode with only sporadic bursts of transmit data. This reduces power consumption. The Aprisa SR is a packet based radio. Data is sent over the wireless channel in discrete packets / frames, separated in time. The PHY demodulates data within these packets with coherent detection. The Aprisa SR PHY provides carrier, symbol and frame synchronization predominantly through the use of preambles. This preamble prefixes all packets sent over the wireless channel which enables fast Synchronization. Data Link Layer / MAC layer The Aprisa SR PHY enables multiple users to be able to share a single wireless channel; however a DLL is required to manage data transport. The two key components to the DLL are channel access and hop by hop transmission. Channel Access The Aprisa SR radio has two modes of channel access, Access Request and Listen Before Send. Option Function Access Request Channel access scheme where the base stations controls the communication on the channel. Remotes ask for access to the channel, and the base station grants access if the channel is not occupied. Listen Before Send Channel access scheme where network elements listen to ensure the channel is clear, before trying to access the channel. Aprisa SR User Manual 22 | About the Radio Access Request This scheme is particularly suited to digital SCADA systems where all data flows through the base station. In this case it is important that the base station has contention-free access as it is involved in every transaction. The channel access scheme assigns the base station as the channel access arbitrator and therefore inherently it has contention-free access to the channel. This means that there is no possibility of contention on data originating from the base station. As all data flows to or from the base station, this significantly improves the robustness of the system. All data messages are controlled via the AG (access grant) control message and therefore there is no possibility of contention on the actual end user data. If a remote station accesses the channel, the only contention risk is on the AR (access request) control message. These control messages are designed to be as short as possible and therefore the risk of collision of these control messages is significantly reduced. Should collisions occur these are resolved using a random back off and retry mechanism. As the base station controls all data transactions multiple applications can be effectively handled, including a mixture of polling and report by exception. Listen Before Send The Listen Before Send channel access scheme is realized using Carrier Sense Multiple Access (CSMA). In this mode, a pending transmission requires the channel to be clear. This is determined by monitoring the channel for other signals for a set time prior to transmission. This results in reduced collisions and improved channel capacity. There are still possibilities for collisions with this technique e.g. if two radios simultaneously determine the channel is clear and transmit at the same time. In this case an acknowledged transaction may be used. The transmitter requests an ACK to ensure that the transmission has been successful. If the transmitter does not receive an ACK, then random backoffs are used to reschedule the next transmission. Hop by Hop Transmission Hop by Hop Transmission is realized in the Aprisa SR by adding a MAC address header to the packet. For 802.15.4, there are 2 addresses, the source and destination addresses. Aprisa SR User Manual About the Radio | 23 Network Layer Packet Routing Packet routing is realized in the Aprisa SR by adding a network address header to the packet. This contains source and destination addresses. For the Network Layer, there are 2 addresses, the address of the originating radio and the address of the terminating radio (i.e. end to end network). This is required for routing packets across multiple hops e.g. PMP with repeaters. The Aprisa SR uses an automated method for performing address assignment and routing information. There are two types of packets: unicast and broadcast. Only the base station sends broadcasts which are received by all remote stations. User packets are not interpreted as the radio link is transparent. Traffic Data originating on the base station is broadcast to all repeater stations and remote stations Data originating on a remote station is unicast to the base station only This can be via multiple repeater stations. Data originating on a repeater station is unicast to the base station only Data originating on a base station serial port is terminated on remote station serial ports only Data originating on a base station Ethernet port is terminated on remote station Ethernet ports or serial ports (Terminal Server mode) User Traffic User traffic is prioritized depending on the Serial and Ethernet Data Priority options (see Traffic Settings on Radio > Channel Setup on page 97). If the Serial and Ethernet Data Priority options are equal, then first come first served is invoked. Repeater stations repeat traffic also on a first come first served basis. Management Traffic Management Traffic is prioritized relative to user traffic priority (see Traffic Settings on Radio > Channel Setup on page 97).

Aprisa SR User Manual Product Options | 29 4. Product Options Dual Antenna Port The standard Aprisa SR uses a one or two frequency duplex transmission mode which eliminates the need for a duplexer. However, a dual antenna port option is available for separate transmit and receive antenna connection to support external duplexers or filters. The transmission remains half duplex. Example Part:

Part Number Part Description APSR-N400-012-DO-12-ETAA 4RF SR, BR, 400-470 MHz, 12.5 kHz, DO, 12 VDC, ET, AA Aprisa SR User Manual 30 | Product Options Protected Station The Aprisa SR Protected Station provides radio and user interface protection for Aprisa SR radios. The RF ports and interface ports from two standard Aprisa SR Radios are switched to the standby radio if there is a failure in the active radio. Example Part:

Part Number Part Description APSR-R400-012-SO-12-ETAA 4RF SR, PS, 400-470 MHz, 12.5 kHz, SO, 12 VDC, ET, AA The Aprisa SR Protected Station is comprised of an Aprisa SR Protection Switch and two standard Aprisa SR radios. This configuration provides the ability to hot-swap a failed radio without interrupting user traffic on the active radio. Additionally, retains the full temperature range specification of a single radio. The Aprisa SR radios can be any of the currently available Aprisa SR radio frequency bands, channel sizes or single / dual antenna port options. The Aprisa SR Protected Station can operate as a base station, repeater station or remote station. The protection behavior and switching criteria between the active and standby radios is identical for the three configurations. By default, the Aprisa SR Protected Station is configured with the left hand radio (A) designated as the primary radio and the right hand radio (B) designated as the secondary radio. Each radio is configured with its own unique IP and MAC address and the address of the partner radio. On power-up, the primary radio will assume the active role and the secondary radio will assume the standby role. If, for some reason, only one radio is powered on it will automatically assume the active role. Protected Ports The protected ports are located on the protected station front panel. Switching occurs between the active radio ports and the standby radio ports based on the switching criteria described below. The protected ports include:

Antenna ports ANT/TX and RX (if dual antenna ports used) Ethernet ports 1 and 2 Serial port Aprisa SR User Manual Product Options | 31 Operation In normal operation, the active radio carries all RS-232 serial and Ethernet traffic over the radio link and the standby radio is unused with its transmitter turned off. Both radios are continually monitored for correct operation and alarms are raised if an event occurs. Both the active and standby radios send regular keep alive messages to each other to indicate if they are operating correctly. In the event of a failure on the active radio, the RF link and user interface traffic is automatically switched to the standby radio. The failed radio can then be replaced in the field without interrupting user traffic (see Replacing a Protected Station Faulty Radio on page 36). Configuration Management The Primary and Secondary radios are managed with the embedded web-based management tool, SuperVisor (see Managing the Radio on page 63) by using either the Primary or Secondary IP address. Configuration changes in one of the radios will automatically be reflected in the partner radio. To ensure all remote stations are registered to the correct (active) base station, changes to the Network Table are automatically synchronized from the active radio to the standby radio. The Network Table is only visible on the active radio. This synchronization does not occur if the Hardware Manual Lock is active. Switch Over The switch over to the standby radio can be initiated automatically, on fault detection, or manually via the Hardware Manual Lock switch on the Protection Switch or the Software Manual Lock from SuperVisor. Additionally, it is possible to switch over the radios remotely without visiting the station site, via the remote control connector on the front of the Protection Switch. On detection of an alarm fault the switch over time is less than 0.5 seconds. Some alarms may take up to 5 seconds to be detected. The Protection Switch has a switch guard mechanism to prevent protection switch oscillation. If a switch-

over has occurred, subsequent switch-over triggers will be blocked if the guard time has not elapsed. The guard time starts at 20 seconds and doubles each switch-over to a maximum of 320 seconds and halves after a period of two times the last guard time with no protection switch-overs. Aprisa SR User Manual 32 | Product Options Switching Criteria The Protected Station will switch over operation from the active to the standby radio if any of the configurable alarm events occur, or if there is a loss of the keep alive signal from the active radio. It is possible to configure the alarm events which will trigger the switch over. It is also possible to prevent an alarm event triggering a switch over through the configuration of blocking criteria. Any of the following alarm events can be set to trigger or prevent switching from the active radio to the standby radio (see Events > Events Setup on page 146). PA current Tx reverse power Temperature threshold RSSI Threshold Rx CRC errors Tx AGC Thermal shutdown Thermal shutdown RX Synthesizer Not Locked RF no receive data Port1 Eth no receive data Port2 Eth no receive data Port1 Eth data receive errors Port2 Eth data receive errors Port1 Eth data transmit errors Port2 Eth data transmit errors Port1 Serial Data No RX Data Port1 Serial Data RX Errors USB Port Serial Data No RX Data USB Port Serial Data RX Errors Component failure Calibration failure Configuration not supported Protection Hardware Failure Alarm Input 1 Alarm Input 2 It will not attempt to switch over to a standby radio which has power failure. It will also not switch over to a standby radio with an active alarm event which has been configured as a blocking criteria. Switch over will be initiated once either of these conditions is rectified, i.e. power is restored or the alarm is cleared. Aprisa SR User Manual Product Options | 33 Hardware Manual Lock The Hardware Manual Lock switch on the Protection Switch provides a manual override of the active /

standby radio. When this lock is activated, the selected radio (A or B) becomes the active radio regardless of the Software Manual Lock and the current switching or block criteria. When the lock is deactivated (set to the Auto position), the protection will become automatic and switching will be governed by normal switching and blocking criteria. The state of the switch is indicated by the three LEDs on the Protection Switch:

A LED Green Off B LED Locked LED State Off Green Off Off Auto - Radio A is active Auto - Radio B is active Green Off Orange Manual Lock to radio A Off Green Orange Manual Lock to radio B The Protection Switch also has a Software Manual Lock (see Protected Station: Maintenance > Protection on page 190). The Hardware Manual Lock takes precedence over Software Manual Lock if both diagnostic functions are activated i.e. if the Software Manual Lock is set to Primary and the Hardware Manual Lock set to Secondary, the system will set the Secondary radio to Active. When a Hardware Manual Lock is deactivated (set to the Auto position), the Software Manual Lock is re-

evaluated and locks set appropriately. Remote Control The switch over to the standby radio can be initiated via the Remote Control connector on the front of the Protection Switch. This control will only operate if the Hardware Manual Lock switch is set to the Auto position. The inputs are logic inputs with 4700 pullup to +3.3 VDC. They require a pull down to ground to activate the control. The ground potential is available on the connector (see Protection Switch Remote Control Connections on page 227). Aprisa SR User Manual 34 | Product Options Installation Mounting The Aprisa SR Protected Station is designed to mount in a standard 19 inch rack. Cabling The Aprisa SR Protected Station is delivered pre-cabled with power, interface, management and RF cables. The set of interconnect cables is available as a spare part (see Spares on page 37). Power A +10.5 to +30 V DC external power source must be connected to both the A and B Phoenix Contact 2 pin male power connectors located on the protected station front panel. The A power input powers the A radio and the B power input powers the B radio. The protection switch is powered from the A power input or the B power input (which ever is available). The maximum combined power consumption is 35 Watts. Aprisa SR User Manual Maintenance Product Options | 35 Changing the Protected Station IP Addresses To change the IP address of a Protected Station radio:

1. Change the IP address of either or both the Primary Radio and Secondary radio (see Protected Station: on page 186). Changes in these parameters are automatically changed in the partner radio. Protected Station Software Upgrade The Protected Station software upgrade can be achieved without disruption to traffic. Network Software Upgrade This process allows customers to upgrade their Aprisa SR network from the central base station location without need for visiting remote sites. The Software Pack is loaded into the base station with the file transfer process (see Software > File Transfer on page 156) and distributed via the radio link to all remote stations. When all remote stations receive the Software Pack version, the software can be remotely activated on all remote stations.

Aprisa SR User Manual 38 | Product Options Data Driven Protected Station The Aprisa SR Data Driven Protected Station provides radio and RS-232 serial port user interface protection for Aprisa SR radios. Example Part:

Part Number Part Description APSR-D400-012-DO-12-ETAA 4RF SR, PD, 400-470 MHz, 12.5 kHz, DO, 12 VDC, ET, AA The Aprisa SR Data Driven Protected Station shown is comprised of two standard Aprisa SR dual antenna port option radios and two external duplexers mounted on 19" rack mounting shelves. The Aprisa SR radios can be any of the currently available Aprisa SR radio frequency bands, channel sizes or single / dual antenna port options. By default, the Aprisa SR Data Driven Protected Station is configured with the left hand radio (A) designated as the primary radio and the right hand radio (B) designated as the secondary radio. Each radio is configured with its own unique IP and MAC address and the address of the partner radio. On power-up, the primary radio will assume the active role and the secondary radio will assume the standby role. If, for some reason, only one radio is powered on it will automatically assume the active role. Operation The active radio is determined explicitly by which radio receives data on its RS-232 serial port input from the interface. The active radio carries all RS-232 serial traffic over its radio link and the standby radio is unused with its transmitter turned off. If data is received on the RS-232 serial port interface input of the standby radio, it will immediately become the active radio and the radio which was active will become the standby radio. Aprisa SR User Manual Product Options | 39 Switch Over The active radio is determined explicitly by which radio receives data on its RS-232 serial port. The switching and blocking criteria used for the standard Protected Station do not apply. This means that events and alarms on the unit are not used as switching criteria. Configuration Management The Primary and Secondary radios are managed with the embedded web-based management tool, SuperVisor (see Managing the Radio on page 63) by using either the Primary or Secondary IP address. Configuration changes in one of the radios will automatically be reflected in the partner radio. Changes to the Network Table are automatically synchronized from the active radio to the standby radio but the Network Table is only visible on the active radio.

However, it can also be used to provide an additional RS-232 DCE serial port for customer traffic. This is accomplished with a USB to RS-232 serial converter cable. This plugs into the USB host port connector and can be terminated with the required customer connector. This additional RS-232 serial port is enabled with the SuperVisor mode setting in Serial Port Settings (see Serial > Port Setup on page 103). The Aprisa SR USB port has driver support for these USB serial converters. Other USB serial converters may not operate correctly. USB RS-232 operation The USB serial converter buffers the received data frames into 64 byte blocks separated by a small inter-

frame gap. For the majority of applications, this fragmentation of egress frames is not an issue. However, there are some applications that may be sensitive to the inter-frame gap, therefore, these applications need consideration. A 5 ms inter-frame is recommended for the applications that are sensitive to inter-frame gap timings. On a USB RS-232 port, Modbus RTU can operate up to 9600 baud with all packet sizes and up to 115200 if the packet size is less than 64 bytes. The standard RS-232 port is fully compatible with Modbus RTU at all baud rates.

Aprisa SR User Manual 6. Preparation Bench Setup Before installing the links in the field, it is recommended that you bench-test the links. A suggested setup for basic bench testing is shown below:

Preparation | 49 When setting up the equipment for bench testing, note the following:

Earthing Each radio should be earthed at all times. The radio earth point should be connected to a protection earth. Attenuators In a bench setup, there should be 60 - 80 dB at up to 1 GHz of 50 ohm coaxial attenuation, capable of handling the transmit power of +37 dBm (5 W) between the radios antenna connectors. Splitter If more than two radios are required in your bench setup, a multi-way splitter is required. The diagram shows a two way splitter. This splitter should be 50 ohm coaxial up to 1 GHz and capable of handling the transmit power of +37 dBm (5 W). Cables Use double-screened coaxial cable that is suitable for use up to 1 GHz at 1 metre. CAUTION: Do not apply signals greater than +10 dBm to the antenna connection as they can damage the receiver. Aprisa SR User Manual 50 | Preparation Path Planning The following factors should be considered to achieve optimum path planning:

Antenna Selection and Siting Coaxial Cable Selection Linking System Plan Antenna Selection and Siting Selecting and siting antennas are important considerations in your system design. The antenna choice for the site is determined primarily by the frequency of operation and the gain required to establish reliable links. Base or Repeater Station The predominant antenna for a base station or a repeater station is an omni-directional collinear gain antenna. Omni Directional Collinear Antennas Factor Frequency Gain Explanation Often used in 380-530 MHz bands Varies with size (5 dBi to 8 dBi typical) Wind loading Minimal Tower aperture required Minimal Size Polarization Range from 2 m to 3 m length Vertical Aprisa SR User Manual Remote station There are two main types of directional antenna that are commonly used for remote stations, Yagi and corner reflector antennas. Preparation | 51 Yagi Antennas Factor Frequency Gain Explanation Often used in 350-600 MHz bands Varies with size (typically 11 dBi to 16 dBi) Stackable gain increase 2 Yagi antennas (+ 2.8 dB) 4 Yagi antennas (+ 5.6 dB) Size Range from 0.6 m to 3 m in length Front to back ratio Low (typically 18 to 20 dB) It is possible to increase the gain of a Yagi antenna installation by placing two or more of them in a stack. The relative position of the antennas is critical. Example of stacked antennas Aprisa SR User Manual 52 | Preparation Corner Reflector Antennas Factor Frequency Gain Size Explanation Often used in 330-960 MHz bands Typically 12 dBi Range from 0.36 m to 0.75 m in length Front to back ratio High (typically 30 dB) Beamwidth Broad (up to 60) Antenna Siting When siting antennas, consider the following points:

A site with a clear line of sight to the remote radio is recommended. Pay particular attention to trees, buildings, and other obstructions close to the antenna site. Example of a clear line-of-sight path Any large flat areas that reflect RF energy along the link path, for instance, water, could cause multipath fading. If the link path crosses a feature that is likely to cause RF reflections, shield the antenna from the reflected signals by positioning it on the far side of the roof of the equipment shelter or other structure. Example of a mid-path reflection path The antenna site should be as far as possible from other potential sources of RF interference such as electrical equipment, power lines and roads. The antenna site should be as close as possible to the equipment shelter. Wide angle and zoom photographs taken at the proposed antenna location (looking down the proposed path), can be useful when considering the best mounting positions. Aprisa SR User Manual Preparation | 53 Coaxial Feeder Cables To ensure maximum performance, it is recommended that you use good quality low-loss coaxial cable for all feeder runs. When selecting a coaxial cable consider the following:

Managing the Radio SuperVisor The Aprisa SR contains an embedded web server application (SuperVisor) to enable element management with any major web browser (such as Mozilla Firefox or Microsoft Internet Explorer). SuperVisor enables operators to configure and manage the Aprisa SR base station radio and repeater /

remote station radios over the radio link. The key features of SuperVisor are:

Full element management, configuration and diagnostics Manage the entire network from the Base Station (remote management of elements) Managed network software distribution and upgrades Performance and alarm monitoring of the entire network, including RSSI, alarm states, time-

stamped events, etc. View and set standard radio configuration parameters including frequencies, transmit power, channel access, serial, Ethernet port settings Set and view security parameters User management Connecting to SuperVisor The predominant management connection to the Aprisa SR radio is with an Ethernet interface using standard IP networking. There should be only one Ethernet connection from any radio in the network to the management network. The Aprisa SR has a factory default IP address of 169.254.50.10 with a subnet mask of 255.255.0.0. This is an IPv4 Link Local (RFC3927) address which simplifies the connection to a PC. Each radio in the network must be set up with a unique IP address on the same subnet. The Aprisa SR Protected Station radio A (left radio) has a factory default IP address of 169.254.50.10 and radio B (right radio) has a factory default IP address of 169.254.50.20, both with a subnet mask of 255.255.0.0. To change the Aprisa SR IP address:

1. Set up your PC for a compatible IP address e.g. 169.254.50.1 with a subnet mask of 255.255.0.0. 2. Connect your PC network port to one of the Aprisa SR Ethernet ports. 3. Open a browser and enter http://169.254.50.10. 4. Login to the radio with the default Username admin and Password admin. 5. Change the IP address to conform to the network plan in use. Aprisa SR User Manual 64 | Managing the Radio Management PC Connection The active management PC must only have one connection to the network as shown by path . There should not be any alternate path that the active management PC can use via an alternate router or alternate LAN that would allow the management traffic to be looped as shown by path . When logging into a network, it is important to understand the relationship between the Local Radio and the Remote Radios. The Local Radio is the radio that your IP network is physically connected to. If the Local Radio is a base station, SuperVisor manages the base station and all the repeater stations and remote stations in the network. If the Local Radio is a remote station or repeater station, SuperVisor only manages the remote / repeater station radio logged into. If the user is at the remote station and connects SuperVisor directly to the remote radio via their computer, all relevant features are still available. This includes the ability to monitor the Last received packet RSSI. If ICMP is enabled on the base station, the user will also be able to ping the base station to confirm the connectivity. Aprisa SR User Manual Managing the Radio | 65 PC Settings for SuperVisor To change the PC IP address:

If your PC has previously been used for other applications, you may need to change the IP address and the subnet mask settings. You will require Administrator rights on your PC to change these. Windows XP example:

Aprisa SR User Manual 78 | Managing the Radio Standard Radio Terminal Terminal > Summary TERMINAL SUMMARY This page displays the current settings for the Terminal parameters. OPERATING SUMMARY Operating Mode This parameter displays the current Operating Mode i.e. if the radio is operating as a base station, repeater station or remote station. Interface Mode This parameter displays the Interfaces available for traffic on the radio (see Maintenance > Licence on page 140). Aprisa SR User Manual Managing the Radio | 79 TX Frequency (MHz) This parameter displays the current Transmit Frequency in MHz. TX Power (dBm) This parameter displays the current Transmit Power in dBm. RX Frequency (MHz) This parameter displays the current Receive Frequency in MHz. Channel Width (kHz) This parameter displays the current Channel Width in kHz. Network ID This parameter is the network ID of this base station node and its remote / repeater stations in the network. The entry is four hex chars (not case sensitive). Node Address The Node Address of the base station is 0000. If the Node Address shown is FFFE, this radio is a remote station or repeater station but has not been registered with the base station. The base station will automatically allocate a Node Address to all its registered repeater station and remote station radios. This address can be between 000B to 01FE. Network Radius This parameter displays the maximum number of hops in this network. Network Repeaters Proximity This parameter displays the proximity of repeaters in the network. Inband Management This parameter displays the status of the Inband Management option. Inband Management Timeout (sec) This parameter displays the number of seconds that the base station waits for a response from a Remote or repeater station before aborting the Inband Management request. Aprisa SR User Manual 80 | Managing the Radio Terminal > Details MANUFACTURING DETAILS Radio Serial Number This parameter displays the Serial Number of the radio (shown on the enclosure label). Sub-Assembly Serial Number This parameter displays the Serial Number of the printed circuit board assembly (shown on the PCB label). Aprisa SR User Manual Managing the Radio | 81 Radio MAC Address This parameter displays the MAC address of the radio. Active Software Version This parameter displays the version of the software currently operating the radio. Previous Software Version This parameter displays the software version that was running on the radio prior to the current software being activated. A new radio from the factory will display None for the Previous SW Version. Aprisa SR User Manual 82 | Managing the Radio Terminal > Device TERMINAL DETAILS The data entry in the next four fields can be up to 40 characters but cannot contain invalid characters. A popup warns of the invalid characters:

1. Enter the Terminal Name. 2. Enter the Location of the radio. 3. Enter a Contact Name. The default value is support@4RF.com. 4. Enter the Contact Details. Aprisa SR User Manual Managing the Radio | 83 RF NETWORK DETAILS Network ID (network) This parameter sets the network ID of this base station node and its remote / repeater stations in the network. The entry is four hexadecimal chars (not case sensitive). The default setting is CAFE. Network Radius This parameter sets the maximum number of hops in this network e.g. if the Network Radius is set to 2, a message from that node will only pass 2 hops before it is blocked. The default setting is 1. All stations in the network should be set to the same value. Network Repeaters Proximity This parameter is set in base stations and repeater stations to indicate the proximity of repeaters in the network. It has no affect if the Network Radius is set to 1. The default setting is Separated Coverage. Option Function No Repeater Use when there are no repeaters in the network. Single Repeater Only Use when there is only one repeater in the network. Overlapping Coverage Separated Coverage Use for multiple one hop repeaters where the remote station can see more than one repeater or repeaters can see each other. The communication protocol is slower because each repeater is addressed individually and in-turn. Use for multiple one hop repeaters where the remote station can only see one repeater and the repeaters cant see each other. This option provides better network downlink performance than the Overlapping Coverage option. However, if the repeaters can see each other, the resultant collisions will cause corruptions and dramatically reduce network downlink performance. Inband Management This parameter sets the Inband Management option. If the Inband Management option is enabled, SuperVisor operating on a base station can also manage all the remote / repeater stations in the network. Inband Management Timeout (sec) This parameter sets the Inband Management timeout period. This determines the time the base station waits for a response from a Remote or repeater station before aborting the Inband Management request. The default setting is 10 seconds. Aprisa SR User Manual 84 | Managing the Radio TERMINAL DATE AND TIME Set the Time Format, Time, Date Format and Date. This information is controlled from a software clock. Date and Time Synchronization This Date and Time Synchronization feature allows a radio to synchronize its date and time from an SNTP server. It would predominantly be used on the base station but could be used on a remote station. Using the SNTP feature will ensure that all radios in the network has the same date and time required for accurate network diagnostics. For high availability time/date synchronization, SNTP can be synchronized from two SNTP servers for server backup. The default setting is Disabled. Option Disabled SNTP Function No SNTP Date and Time Synchronization Date and Time will be synchronized to a SNTP server The base station periodically sends a broadcast message to the remote stations to synchronize the radio date and time. Auto Synchronization Period (s) This parameter sets the number of seconds between the end of the last synchronization and the next synchronization attempt. The minimum period is 60 seconds. A period of 0 seconds will disable synchronization attempts. Time Server 1 Address This parameter sets the IP address of the first priority SNTP server. If the synchronization is successful to this server, Time Server 2 Address will not be used. Time Server 2 Address This parameter sets the IP address of the second priority SNTP server. If the synchronization fails using the SNTP server on Time Server 1 Address, synchronization will be attempted to the SNTP server on this address. Synchronization Status This field shows the status of the current synchronization or the result of the last synchronization. Synchronize Now This Synchronize Now button provides manual Synchronization.

Refer to your site license details when setting these fields. TRANSMITTER / RECEIVER Important:

1. Changing the remote / repeater station frequencies will disable all management communication to the remote / repeater stations but then by changing the base station to match the remote / repeater stations, the radio links will be restored as will the management communication. 2. Enter the TX frequency and the RX frequency and then click Save. This is to prevent remote management communication from being lost before both frequencies have been changed in the remote stations. TX and RX Frequencies. The TX and RX frequencies entered must be within the frequency tuning range of the product frequency band (see Frequency Bands on page 232). If the frequency entered is not resolvable to the synthesizer step size for the frequency band it is rejected. For example; a 400 MHz radio has a synthesizer step size of 6.250 kHz. The default setting is 330 MHz for a UHF radio and 136 MHz for VHF radio. The TX and RX frequencies can be single frequency duplex or dual frequency duplex. Dual frequency duplex is often used for reasons of:

Channel Planning Network Efficiencies Regulatory rules Aprisa SR User Manual Single Frequency Operation The TX and RX frequencies of the base station, repeater station and all the remote stations are on the same frequency. Managing the Radio | 93 To change the TX and RX frequencies:

1. Change the TX and RX frequencies of the remote stations operating from the repeater station to the new frequency. The radio links to these remote stations will fail. 2. Change the TX and RX frequencies of the repeater station operating from the base station to the new frequency. The radio links to the repeater station and its remote stations will fail. 3. Change the TX and RX frequencies of the remote stations operating from the base station to the new frequency. The radio links to these remote stations will fail. 4. Change the TX and RX frequencies of the base station to the new frequency. The radio links to all stations will restore. Aprisa SR User Manual 94 | Managing the Radio Dual Frequency No Repeater The TX frequency of all the remote stations matches the RX frequency of the base station. The RX frequency of all the remote stations matches the TX frequency of the base station. To change the TX and RX frequencies:

1. For all the remote stations, change the RX frequency to frequency A and the TX frequency to frequency B. The radio links to the remote stations will fail. 2. For the base station, change the TX frequency to frequency A and the RX frequency to frequency B. The radio links to the remote stations will restore. Aprisa SR User Manual Managing the Radio | 95 Dual Frequency with Repeater The TX frequency of the remote stations associated with the base station matches the RX frequency of the base station. The TX frequency of the repeater station associated with the base station matches the RX frequency of the base station. The TX frequency of the remote stations associated with the repeater station matches the RX frequency of the repeater station. The RX frequency of the remote stations associated with the base station matches the TX frequency of the base station. The RX frequency of the repeater station associated with the base station matches the TX frequency of the base station. The RX frequency of the remote stations associated with the repeater station matches the TX frequency of the repeater station. To change the TX and RX frequencies:

1. For all the remote stations operating from the repeater station, change the RX frequency to frequency A and the TX frequency to frequency B. The radio links to these remote stations will fail. 2. For the repeater station, change the TX frequency to frequency A and the RX frequency to frequency B. 3.

For all the remote stations operating from the base station, change the TX frequency to frequency A and the RX frequency to frequency B. Aprisa SR User Manual 96 | Managing the Radio TX Power The transmitter power is the power measured at the antenna output port when transmitting. The transmitter power has a direct impact on the radio power consumption (see Power Consumption on page 236) and Save the change. The default setting is +37 dBm. Note: The Aprisa SR transmitter contains power amplifier protection which allows the antenna to be disconnected from the antenna port without product damage. Aprisa SR User Manual Radio > Channel Setup Managing the Radio | 97 CHANNEL SETTINGS Access Scheme This parameter sets the Media Access Control (MAC) used by the radio for over the air communication. Option Function Access Request Channel access scheme where the base stations controls the communication on the channel. Remotes ask for access to the channel, and the base station grants access if the channel is not occupied. This mode is a general purpose access method for high and low load networks. Listen Before Send without Acknowledgement Channel access scheme where network elements listen to ensure the channel is clear, before trying to access the channel. This mode is optimised for low load networks and repeated networks. Acknowledgements are disabled. Listen Before Send with Acknowledgement Channel access scheme where network elements listen to ensure the channel is clear, before trying to access the channel. This mode is optimised for low load networks and repeated networks. With Acknowledgement, unicast requests from the remote station are acknowledged by the base station to ensure that the transmission has been successful. If the remote station does not receive an acknowledgement, then random back-offs are used to reschedule the next transmission. Enabling acknowledgments increases reliability of transport but reduces available channel capacity so if application has the capability to handle lost or duplicate messages, the Access Scheme should be set to Listen Before Send without Acknowledgement. The default setting is Access Request. Aprisa SR User Manual

98 | Managing the Radio Packet Size (Bytes) This parameter sets the maximum over-the-air packet size in bytes. A smaller maximum Packet Size is beneficial when many remote stations or repeater stations are trying to access the channel. The default setting is 1550 bytes. As radios dispatched from the factory have a Packet Size set to the maximum value of 1550 bytes, if a new radio is installed in an existing Field Access Network (network), the Packet Size must be changed to ensure it is the same value for all radios in the network. The new radio will not register an existing network if the Packet Size is not the same as the other radios in the network. This packet size includes the wireless protocol header and security payload (0 to 16 bytes). The length of the security header depends on the level of security selected. When the security setting is 0, the maximum user data transfer over-the-air is 1516 bytes. When encryption is enabled, the entire packet of user data (payload) is encrypted. If authentication is being used, the security frame will be added (up to 16 bytes). The wireless protocol header is then added which is proprietary to the Aprisa SR. This is not encrypted. Packet Time to Live (ms) This Time To Live (TTL) parameter sets the time a packet is allowed to live in the system before being dropped if it cannot be transmitted over the air. It is used to prevent old, redundant packets being transmitted through the Aprisa SR network. The default setting is 1500 ms. In the case of serial poll SCADA networks such as MODBUS and IEC 60870.50.101, it is important to ensure the replies from the RTU are in the correct sequence and are not timed out replies from Master requests. If the TTL value is too long, the SCADA master will detect sequence errors. It is recommended to use a TTL which is half the serial SCADA timeout. This is commonly called the scan timeout or link layer time out or retry timeout. When using TCP protocols, a TTL of 1500 ms is recommended because a TCP re-transmission usually occurs after approximately 3 second. In SCADA networks which use both serial and Ethernet, it is recommended that the TTL is set to half the serial SCADA timeout for serial remotes, and 1500 ms for Ethernet (TCP) remotes. For example, if the serial SCADA timeout is 1000 ms, a remote radio which is connected to the serial RTU should be set to 500 ms, a remote radio which is connected to a Ethernet (TCP) RTU should have a 1500 ms timeout. In this case, the base station TTL should be set to 1500 ms as well; or which ever is the longer TTL of serial or Ethernet. Aprisa SR User Manual Managing the Radio | 99 Packet Filtering Each Aprisa SR radio can filter packets not destined for itself. The Packet Filtering parameter controls this functionality. In an Aprisa SR network, all communication from remote stations is destined for the base station in the Aprisa SR network communication protocol. In a repeater network, a remote station will send a message to the base station. The repeater station will receive this and then repeat the message. The repeated message will then be received by the base station. Other remote stations connected to the repeater station will receive this message and depending on the Packet Filtering parameter, either forward this packet or discard it. This filtering capability can provide the ability for remote stations to communicate with each other when connected to a repeater, particularly useful in the event of losing communication with a SCADA Master, assuming the Aprisa SR network is still operational. IP Header Compression must be disabled for this feature to operate correctly (see IP Header Note:

Compression Ratio on page 101). Option Disabled Automatic Function Every packet received by the radio will be forwarded to the relevant interface. The radio will filter (discard) packets not destined for itself according to the Aprisa SR traffic protocols The default setting is Automatic. Note: The Aprisa SR network is transparent to the protocol being transmitted; therefore the Packet Filtering parameter is based on the Aprisa SR addressing and network protocols, not the user (SCADA, etc.) traffic protocols. Serial Data Stream Mode This parameter controls the traffic flow in the radio serial ports. Option Broadcast Segregate Function Serial port traffic from the network is broadcast on all serial ports on this radio. This will include the RS-232 port derived from the USB port. Serial port traffic from the network from a specific port number is directed to the respective serial port only. The default setting is Broadcast. Aprisa SR User Manual 100 | Managing the Radio TRAFFIC SETTINGS Serial Data Priority The Serial Data Priority controls the priority of the serial customer traffic relative to the Ethernet customer traffic. If equal priority is required to Ethernet traffic, this setting must be the same as the Ethernet Data Priority setting (see Ethernet Data Priority on page 100). The serial data priority can be set to Very High, High, Medium and Low. The default setting is Very High. A queuing system is used to prioritize traffic from the serial and Ethernet interfaces for over the air transmission. A weighting may be given to each data type and this is used to schedule the next transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a higher weighting it will be transmitted first. The serial buffer is 20 serial packets (1 packet can be up to 512 bytes). There are four priority queues in the Aprisa SR: Very High, High, Medium and Low. Data is added to one of these queues depending on the priority setting. Data leaves the queues from highest priority to lowest:

the Very High queue is emptied first, followed by High then Medium and finally Low. Ethernet Data Priority The Ethernet Data Priority controls the priority of the Ethernet customer traffic relative to the serial customer traffic. If equal priority is required to serial traffic, this setting must be the same as the Serial Data Priority setting (see Serial Data Priority on page 100) The Ethernet Data Priority can be set to Very High, High, Medium and Low. The default setting is Very High. A queuing system is used to prioritize customer traffic from the serial and Ethernet interfaces for over the air transmission. A weighting may be given to each data type and this is used to schedule the next transmission over the air e.g. if there are pending data packets in multiple buffers but serial data has a higher weighting it will be transmitted first. The Ethernet buffer is 10 Ethernet packets (1 packet can be up to Ethernet MTU, 1500 bytes). There are four priority queues in the Aprisa SR: Very High, High, Medium and Low. Data is added to one of these queues depending on the priority setting. Data leaves the queues from highest priority to lowest:

the Very High queue is emptied first, followed by High then Medium and finally Low. Ethernet Management Priority The Ethernet Management Priority controls the priority of the Ethernet management traffic relative to Ethernet customer traffic. The Ethernet Management Priority can be set to Very High, High, Medium and Low. The default setting is Medium. Aprisa SR User Manual Background Bulk Data Transfer Rate This parameter sets the data transfer rate for large amounts of management data. Managing the Radio | 101 Function Utilizes more of the available capacity for large amounts of management data. Highest impact on user traffic. Utilizes a moderate of the available capacity for large amounts of management data. Medium impact on user traffic. Utilizes a minimal of the available capacity for large amounts of management data. Lowest impact on user traffic. Option High Medium Low The default setting is high. DATA COMPRESSION IP Header Compression Ratio The IP Header Compression implements TCP/IP ROHC v2 (Robust Header Compression v2. RFC4995, RFC5225, RFC4996) to compress the IP header. IP Header Compression allows for faster point to point transactions, but only in a star network. IP Header Compression module comprises of two main components, Compressor and Decompressor. Both these components maintain some state information for an IP flow to achieve header compression. However, for reasons like packet drops or station reboots this state information can go out of sync between compressor and decompressor resulting in compression and/or decompression failure resulting in loss of packets. The Compression Ratio controls the rate at which compressor and decompressor synchronize state information with each other. Frequent synchronization results in reduced ratio. Option Function Compression Disabled High Medium Low Disables IP Header Compression. State information is synchronized less frequently thus achieving the best compression ratio. State information is synchronization less frequently than High setting but more frequently than Low setting. State information is synchronized frequently thus reducing the compression ratio. The default setting is High. When IP Header Compression is enabled, it is important that the Network Radius is set correctly. If it was incorrectly set to 1, header compression could not be interpreted by radius 2 radios.

See Serial > Port Setup on page 103 for configuration options. Aprisa SR User Manual Serial > Port Setup This page provides the setup for the serial port settings. Managing the Radio | 103 SERIAL PORTS SETTINGS Note: The current Aprisa SR has one serial port so there will be only one record. Name This parameter sets the port name which can be up to 32 characters. Option Function SerialPort1 USB Serial Port This is the normal RS-232 serial port provided with the RJ45 connector. This is the additional RS-232 serial port provided with the USB Host Port

(see USB RS-232 Serial Port on page 43). connector with a USB to RS-232 RJ45 converter cable Mode This parameter defines the mode of operation of the serial port. The default setting is Standard. Option Disabled Standard Function The serial port is not required. The serial port is communicating with serial ports on other stations. Terminal Server A base station Ethernet port can communicate with both Ethernet ports and serial ports on remote stations. RS-232 traffic is encapsulated in IP packets (see Serial > Port Setup TERMINAL SERVER SETTINGS on page 105). Aprisa SR User Manual 104 | Managing the Radio Baud Rate (bit/s) This parameter sets the baud rate to 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600 or 115200 bit/s. The default setting is 115200 bit/s. Character Length (bits) This parameter sets the character length to 7 or 8 bits. The default setting is 8 bits. Parity This parameter sets the parity to Even, Odd or None. The default setting is None. Stop Bits (bits) This parameter sets the number of stop bits to 1 or 2 bits. The default setting is 1 bit. Flow Control This parameter sets the flow control of the serial port. The default setting is Disabled. Option None CTS-RTS Function The Aprisa SR radio port (DCE) CTS is in a permanent ON (+ve) state. This does not go to OFF if the radio link fails. CTS / RTS hardware flow control between the DTE and the Aprisa SR radio port (DCE) is enabled. If the Aprisa SR buffer is full, the CTS goes OFF. In the case of radio link failure the signal goes to OFF (-ve) state. In terminal server mode, the serial packet is no different from an Ethernet packet and travels through various packet queues before being transmitted over the air. Thus, the serial flow control has no affect in terminal server mode. Inter-Frame Gap (chars) This parameter defines the gap between successive serial data frames. It is used to delimit the serial data to define the end of a packet. The Inter-Frame Gap limits are 0.5 to 16 chars. The default setting is 3.5 chars. Aprisa SR User Manual Managing the Radio | 105 TERMINAL SERVER SETTINGS This menu item is only applicable if the serial port has an operating mode of Terminal Server. The Terminal Server operating mode provides encapsulation of serial data into an IP packet (TCP or UDP). A server connected to a base station Ethernet port can communicate with all remote station Ethernet ports and serial ports. Note: The current Aprisa SR has one serial port so there will be only one record. Local Address This parameter displays the IP address of this radio. Port This parameter sets the port number of the local serial port. The valid port number range is greater than or equal to 1024 and less than or equal to 49151 but with exclusions of 0, 5445, 6445, 9930 or 9931. The default setting is 20000. Remote Address This parameter sets the IP address of the server connected to the base station Ethernet port. Port This parameter sets the port number of the server connected to the base station Ethernet port. The default setting is 0. Aprisa SR User Manual 106 | Managing the Radio Protocol This parameter sets the IP protocol used for terminal server operation. The default setting is TCP. Mode This parameter defines the mode of operation of the terminal server connection. The default setting is Client and Server. Option Client Server Client and Server Function The radio will attempt to establish a TCP connection with the specified remote unit. The radio will listen for a TCP connection on the specified local port. Data received from any client shall be forwarded to the associated serial port while data received from that serial port shall be forwarded to every client with an open TCP connection. If no existing TCP connections exist, all data received from the associated serial port shall be discarded. The radio will listen for a TCP connection on the specified local port and if necessary, establish a TCP connection with the specified remote unit. Data received from any client shall be forwarded to the associated serial port while data received from that serial port shall be forwarded to every client with an open TCP connection. Inactivity Timeout (seconds) This specifies the duration (in seconds) to automatically terminate the connection with the remote TCP server if no data has been received from either the remote TCP server or its associated serial port for the duration of the configured inactivity time. TCP Keep Alive A TCP keepalive is a message sent by one device to another to check that the link between the two is operating, or to prevent the link from being broken. If the TCP Keep Alive is enabled, the radio will be notified if the TCP connection fails. If the TCP Keep Alive is disabled, the radio relies on the Inactivity Timeout to detect a TCP connection failure. The default setting is disabled. Note: An active TCP Keep Alive will generate a small amount of extra network traffic.

SNMPv3 With Authentication Only Only SNMPv3 transactions authenticated using HMAC-MD5 or HMAC-SHA will be accepted. The default setting is All Versions. The default SNMPv3 with Authentication User Details provided are:

User Name noAuthUser authUserMD5 authUserSHA Authentication Type Context Name

MD5 SHA noAuth auth auth Authentication Passphrase noAuthUser authUserMD5 authUserSHA Aprisa SR User Manual Managing the Radio | 121 SNMPv3 Authentication Passphrase The Authentication Passphrases can be changed via SNMP (not SuperVisor). When viewing / managing the details of the users via SNMP, the standard SNMP-USER-BASED-SM-MIB interface is used. This interface can be used to change the Authentication Passphrase of the users. The Authentication Passphrase of the user required to be changed cannot be changed by the same user i.e a different user must be used for the transactions. To change a user authentication passphrase:

1. SET the usmUserStatus object for that user to Not In Service 2. GET the usmUserSpinLockobject 3. SET the usmUserSpinLockobject with the value that was just GOT in the previous step 4. SET the usmUserAuthKeyChange to the new Authentication key string 5. SET the usmUserPrivKeyChangeto the new Privacy key string 6. SET the usmUserStatus object for that user to Active Note that the key string for steps 4 and 5 are 32 octet hexadecimal values. This string is generated based on the old passphrase and new passphrase as specified in RFC2274. The utility encode_keychange.exe, available from NET-SNMP open source applications, can be used to generate this string. An example command to generate a new Authentication key string for the default desUserMD5 is:

encode_keychange t md5 O desUserMD5 N desUserMD5Auth E 0x0100DC An example command to generate a new Privacy key string for the default desUserMD5 is:

encode_keychange t md5 O desUserMD5 N desUserMD5Priv E 0x0100DC These command executions will return a 32 Octet Hexadecimal string that can be used in steps 4 and 5 above.

Aprisa SR User Manual 124 | Managing the Radio Security > SNMP In addition to web-based management (SuperVisor), the network can also be managed using the Simple Network Management Protocol (SNMP). MIB files are supplied, and these can be used by a dedicated SNMP Manager, such as Castle Rocks SNMPc, to access most of the radios configurable parameters. For communication between the SNMP manager and the radio, Access Controls and Community strings must be set up as described in the following sections. A SNMP Community String is used to protect against unauthorized access (similar to a password). The SNMP agent (radio or SNMP manager) will check the community string before performing the task requested in the SNMP message. ACCESS CONTROL SETUP A SNMP Access Control is the IP address of the radio used by an SNMP manager or any other SNMP device to access the radio. The Aprisa SR allows access to the radio from any IP address. Read Only The default Read Only community string is public. Read Write The default ReadWrite community string is private. Aprisa SR User Manual Managing the Radio | 125 SNMP Manager Setup The SNMP manager community strings must be setup to access the base station and remote / repeater stations. To access the base station, a community string must be setup on the SNMP manager the same as the community string setup on the radio (see Security > SNMP on page 124). SNMP access to remote / repeater stations can be achieved by using the radios IP address and the normal community string or by proxy in the base station. SNMP Access via Base Station Proxy To access the remote / repeater stations via the base station proxy, the community strings must be setup on the SNMP manager in the format:

ccccccccc:bbbbbb Where:

ccccccccc is the community string of the base station and bbbbbb is the last 3 bytes of the remote station MAC address (see Network Status > Network Table on page 167) for the remote station MAC address. The SNMP Proxy Support must be enabled for this method of SNMP access to operate (see SNMP Proxy Support on page 120).

Aprisa SR User Manual Maintenance > Advanced Managing the Radio | 141 NETWORK Node Registration Retry (sec) This parameter sets the base station poll time at startup or the remote / repeater station time between retries until registered. The default setting is 10 seconds. Base Station Announcement Period (min) This parameter sets the period between base station polls post startup. The default setting is 1440 minutes (24 hours). When a new base station powers on, it announces its presence and each remote that receives the announcement message will be advised that a new base station is present and that they should re-register. This allows the new base station to populate its Network Table, with knowledge of the nodes in the network. If, during this initial period, there is some temporary path disturbance to one or more remotes, they may miss the initial announcement messages and be left unaware of the base station change. For this reason, the base station must periodically send out announcement messages to pick up any stray nodes and the period of these messages is the base station Announcement Period. Setting this parameter to 0 will stop periodic announcement messages being transmitted. If a critical parameter is changed in the base station, such as IP address, then the change is distributed to the network using base station announcement message. Note that in this case, an announcement is sent immediately independent of the Announcement Period setting. Aprisa SR User Manual 142 | Managing the Radio Node Missed Poll Count This parameter sets the number of times the base station attempts to poll the network at startup or if a duplicate IP is detected when a remote / repeater station is replaced. The default setting is 3. Discover Nodes This parameter when activated triggers the base station to poll the network with Node Missed Poll Count and Node Registration Retry values. Decommission Node This parameter when activated resets the network registrations to remove the entire network from service. Note: Take care using this option. Broadcast Time This parameter when activated sends the base station Date / Time setting to all the remote and repeater stations in the network and sets their Date / Time. This option applies to the base station only. Automatic Route Rediscovery This parameter enables the radio to transmit route discovery messages when packets are unacknowledged. When enabled, unacknowledged unicast packets are converted into uni-broadcast messages and sent through the network. All nodes see the message and populate their routing tables accordingly. When the destination node is reached, it sends a route response message via the shortest path. The intermediate nodes see this message and populate their routing tables in the reverse direction, thus re-

establishing the route. The default setting is disabled. RF Interface MAC address This parameter is only applicable when the radio is part of a Protected Station. This RF Interface MAC address is used to define the MAC address of the Protection Switch. This address is entered into both Protected Station radios in the factory. If a replacement Protection Switch is installed, the replacement unit MAC address must be entered in both radios (see Replacing a Faulty Protection Switch on page 37). The Protection Switch RF Interface MAC address is shown on the Protection Switch label:

Severity Critical Major Minor Warning Function The Critical severity level indicates that a service affecting condition has occurred and an immediate corrective action is required. Such a severity can be reported, for example, when a managed object becomes totally out of service and its capability must be restored. The Major severity level indicates that a service affecting condition has developed and an urgent corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the managed object and its full capability must be restored. The Minor severity level indicates the existence of a non-service affecting fault condition and that corrective action should be taken in order to prevent a more serious

(for example, service affecting) fault. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capacity of the managed object. The Warning severity level indicates the detection of a potential or impending service affecting fault, before any significant effects have been felt. Action should be taken to further diagnose (if necessary) and correct the problem in order to prevent it from becoming a more serious service affecting fault. Information No problem indicated purely information Aprisa SR User Manual Managing the Radio | 147 Suppress This parameter determines if the action taken by an alarm. Option None Traps Function Alarm triggers an event trap and is logged in the radio Alarm is logged in the radio but does not trigger an event trap Traps and Log Alarm neither triggers an event trap nor is logged in the radio Lower Limit / Upper Limit Threshold alarm events have lower and upper limit settings. The alarm is activated if the current reading is outside the limits. Example: 9 RX CRC Errors The Upper Limit is set to 0.7 and the Duration is set to 5 seconds. If in any 5 second period, the total number of errored packets divided by the total number of received packets exceeds 0.7, the alarm will activate. Units (1) The Units parameter shows the unit for the Lower Limit and Upper Limit parameters. Duration This parameter determines the period to wait before an alarm is raised if no data is received. Units (2) This parameter shows the unit for the Duration parameters. Switch This parameter determines if the alarm when active causes a switch over of the Protection Switch. This parameter is only applicable when the radio is part of a Protected Station. Block This parameter determines if the alarm is prevented from causing a switch over of the Protection Switch.

The Software Pack has been loaded into the base station with the file transfer process (see Protected Station: Software > Primary File Transfer on page 199) and distributed via the radio link to all remote stations from the active radio. When all remote stations receive the Software Pack version, the software can be remotely activated on all remote stations. The activation process is monitored by this page. This page is only available when the radio is configured as a Base Station. REMOTE SOFTWARE ACTIVATION When the software pack version has been distributed to all the remote stations, the software is then activated in all the remote stations with this command. If successful, then activate the software pack in the base station to complete the network upgrade. Version This parameter displays the software version for activation. The default version is the software pack version but any valid software version can be entered in the format n.n.n. Aprisa SR User Manual Managing the Radio | 211 To activate software in remote stations:

This process assumes that a Software Pack has been loaded into the base station with the file transfer process (see Software > File Transfer on page 156) and that distributed to all remote radios in the network. Note: Do not navigate SuperVisor away from this page during the activation process (SuperVisor can lose PC focus). 1. Enter the Software Pack version (if different from displayed version). 2. Click on Start Activation. The remote stations will be polled to determine which radios require activation:

Result Function (X of Y) Remote Radios Polled for Partners X is the number of radios polled to determine the number of protected stations in the network. Y is the number of remote radios registered with the base station. Remote Radios Polled for New Version X is the number of radios polled to determine the number of radios that contain the new software version. Y is the number of remote radios registered with the base station. Remote Radios Activated X is the number of radios that contain the new software version and have been activated. Y is the number of radios that contain the new software version and can be activated. Remote Radios On New Version X is the number of radios that has been successfully activated and now running the new version of software. Y is the number of radios that the activation command was executed on. When the activation is ready to start:

Commissioning the radio is a simple process and consists of:

1. Powering up the radios. 2. Configuring all radios in the network using SuperVisor. 3. Aligning the antennas. 4. Testing that the links are operating correctly. 5. Connecting up the client or user interfaces. What You Will Need Appropriately qualified commissioning staff at both ends of each link. Safety equipment appropriate for the antenna location at both ends of each link. Communication equipment, that is, mobile phones or two-way radios. SuperVisor software running on an appropriate laptop, computer, or workstation at the base station radio. Tools to facilitate loosening and re-tightening the antenna pan and tilt adjusters. Predicted receiver input levels and fade margin figures from the radio link budget. Aprisa SR User Manual Managing the Radio | 219 Antenna Alignment A base station omni directional collinear antenna has a vertical polarization. The remote station yagi antennas must also have vertical polarization. Aligning the Antennas Align the remote station yagi antennas by making small adjustments while monitoring the RSSI. The Aprisa SR has a Test Mode which presents a real time visual display of the RSSI on the front panel LEDs. This can be used to adjust the antenna for optimum signal strength (see Test Mode on page 28). Note: Low gain antennas need less adjustment in elevation as they are simply aimed at the horizon. They should always be panned horizontally to find the peak signal. 1. Press and hold the ENTER button on the radio LED panel until all the LEDs flash green (about 3 - 5 seconds). Note: The time for the LEDs to display the RSSI result is variable, depending on the network traffic, and can be up to 5 seconds. Small antenna adjustments should be made and then wait for the display to refresh. The RSSI poll refresh rate can be set with the SuperVisor command Transmit Period (see Maintenance > Test Mode on page 137). 2. Move the antenna through a complete sweep horizontally (pan). Note down the RSSI reading for all the peaks in RSSI that you discover in the pan. 3. Move the antenna to the position corresponding to the maximum RSSI value obtained during the pan. Move the antenna horizontally slightly to each side of this maximum to find the two points where the RSSI drops slightly. 4. Move the antenna halfway between these two points and tighten the clamp. 5. If the antenna has an elevation adjustment, move the antenna through a complete sweep (tilt) vertically. Note down the RSSI reading for all the peaks in RSSI that you discover in the tilt. 6. Move the antenna to the position corresponding to the maximum RSSI value obtained during the tilt. Move the antenna slightly up and then down from the maximum to find the two points where the RSSI drops slightly. 7. Move the antenna halfway between these two points and tighten the clamp. 8. Recheck the pan (steps 2-4) and tighten all the clamps firmly. 9. To exit Test Mode, press and hold the ENTER button until all the LEDs flash red (about 3 5 seconds). Aprisa SR User Manual 9. Maintenance Maintenance | 221 No User-Serviceable Components There are no user-serviceable components within the radio. All hardware maintenance must be completed by 4RF or an authorized service centre. Do not attempt to carry out repairs to any boards or parts. Return all faulty radios to 4RF or an authorized service centre. For more information on maintenance and training, please contact 4RF Customer Services at support@4rf.com. CAUTION: Electro Static Discharge (ESD) can damage or destroy the sensitive electrical components in the radio. Aprisa SR User Manual 222 | Maintenance Radio Software Upgrade A software upgrade can be performed on a single radio or an entire Aprisa SR network (network). Network Software Upgrade This process allows customers to upgrade their Aprisa SR network from the central base station location without need for visiting remote sites. The Software Pack is loaded into the base station with the file transfer process (see Software > File Transfer on page 156) and distributed via the radio link to all remote stations. When all remote stations receive the Software Pack version, the software can be remotely activated on all remote stations. Upgrade Process The Aprisa SR network upgrade operation is indicated in base station and remote stations by a flashing orange AUX LED. To upgrade the entire Aprisa SR network software:

1. Using File Transfer, load the software pack into the base station (see Software > File Transfer on page 156). 2. Distribute the software to the entire network of remote radios (see Software > Remote Distribution on page 162). Note: The distribution of software to remote stations does not stop customer traffic from being transferred. However, due to the volume of traffic, the software distribution process may affect customer traffic. Software distribution traffic is classified as management traffic but does not use the Ethernet management priority setting. Software distribution traffic priority has a fixed priority setting of very low. 3. Activate the software on the entire network of remote radios (see Software > Remote Activation on page 164). Where the new software has been activated, remote stations will re-register with the base station. The remote stations software version can verified with Network Status > Network Table on page 167. 4. Activate the software on the base station radio (see Software > Manager on page 159). Aprisa SR User Manual Maintenance | 223 Single Radio Software Upgrade The software upgrade procedure is different for an Aprisa SR Protected Station (see Protected Station Software Upgrade on page 35). Note: If a radio has been configured for a Protection Type of Redundant (see Protected Station:

Terminal > Operating Mode on page 178), and that radio is no longer part of a Protected Station, the Protection Type must be changed to None before the radio software upgrade can be achieved. File Transfer Method This process allows customers to upgrade a single Aprisa SR radio. The Software Pack is loaded into the radio with the file transfer process (see Software > File Transfer on page 156) and activated (see Software > Manager on page 159). Upgrade Process The Aprisa SR upgrade operation is indicated by a flashing orange AUX LED. To upgrade the Aprisa SR radio software:

1. Unzip the software release files in to the root directory of a USB flash drive. 2. Check that the SuperVisor USB Boot Upgrade setting is set to Disabled (see Software > Setup on page 155). 3. Insert the USB flash drive into the Host Port

. 4. Using File Transfer, load the software pack into the radio (see Software > File Transfer on page 156). 5. Activate the software on the radio (see Software > Manager on page 159). Aprisa SR User Manual 224 | Maintenance USB Boot Upgrade Method A single Aprisa SR radio can also be upgraded simply by plugging a USB flash drive containing the new software into the USB A host port on the Aprisa SR front panel and power cycling the radio. Upgrade Process To upgrade the Aprisa SR radio software:

1. Unzip the software release files in to the root directory of a USB flash drive. 2. Check that the SuperVisor USB Boot Upgrade setting is set to Load and Activate (see Software >

Setup on page 155). 3. Power off the Aprisa SR and insert the USB flash drive into the Host Port

. 4. Power on the Aprisa SR. 5. The software upgrade process is complete when the OK LED lights solid orange. This can take about 2 minutes. The software will have loaded in to the radio Software Pack location. 6. Remove the USB flash drive from the Host Port

. 7. Power cycle the Aprisa SR. Login to the radio being upgraded and go to SuperVisor Software > Manager on page 159. The version of the uploaded software will be displayed in the Software Pack Version field. If the upgrade process did not start, the Aprisa SR could already be operating on the version of software on the USB flash drive. This will be indicated by flashing OK LED and then the OK, DATA and CPU will light steady green. Aprisa SR User Manual Maintenance | 225 If the radio is not operating on the new software (after the power cycle), it could be caused by the SuperVisor USB Boot Upgrade setting set to Load Only (see Software > Setup on page 155). In this case, go to SuperVisor see Software > Manager on page 159 and tick the Software Pack Activate checkbox and click Appy. If any Display Panel LED flashes red or is steady red during the upgrade process, it indicates that the upgrade has failed. This could be caused by incorrect files on the USB flash drive or a radio hardware failure. Software Downgrade Radio software can also be downgraded if required. This may be required if a new radio is purchased for an existing network which is operating on an earlier software release. The downgrade process is the same as the upgrade process.

Product End Of Life Product End Of Life | 239 End-of-Life Recycling Programme (WEEE) The WEEE Directive concerns the recovery, reuse, and recycling of electronic and electrical equipment. Under the Directive, used equipment must be marked, collected separately, and disposed of properly. 4RF has implemented an end-of-life recycling programme to manage the reuse, recycling, and recovery of waste in an environmentally safe manner using processes that comply with the WEEE Directive (EU Waste Electrical and Electronic Equipment 2002/96/EC). The WEEE Symbol Explained This symbol appears on Electrical and Electronic Equipment (EEE) as part of the WEEE (Waste EEE) directive. It means that the EEE may contain hazardous substances and must not be thrown away with municipal or other waste. WEEE Must Be Collected Separately You must not dispose of electrical and electronic waste with municipal and other waste. You must separate it from other waste and recycling so that it can be easily collected by the proper regional WEEE collection system in your area. YOUR ROLE in the Recovery of WEEE By separately collecting and properly disposing of WEEE, you are helping to reduce the amount of WEEE that enters the waste stream. One of the aims of the WEEE directive is to divert EEE away from landfill and encourage recycling. Recycling EEE means that valuable resources such as metals and other materials (which require energy to source and manufacture) are not wasted. Also, the pollution associated with accessing new materials and manufacturing new products is reduced. EEE Waste Impacts the Environment and Health Electrical and electronic equipment (EEE) contains hazardous substances which have potential effects on the environment and human health.
