M n E o O i t a l l a t s n I QUICK START GUIDE The steps below contain the essential information needed to place the OEM trans-

ceiver in service. Because the transceiver is designed for use in other pieces of equipment, these steps assume that prior testing and evaluation have been conducted with the host device. If not, please refer to Section 3.0, Benchtop Setup and Evaluation for interface wiring and configuration details. 1. Mount the transceiver module using the four holes provided. If possible, select a mounting location that allows viewing the status LEDs and provides ready access to the antenna connector. Use standoff hardware to secure the board to the host device. When mounting the board, use care to align the transceivers 16-pin header connector with the mating pins in the host device. 2. Connect the antenna system to the transceiver Use only with antenna/feedline assemblies that have been expressly tested and approved for such service by Microwave Data Systems Inc. Use an MCX-type male connector to attach the antenna to the transceiver. For best performance, antennas should be mounted in the clear, with an unobstructed path in the direction of desired transmission/reception. 3. Apply power and observe the LEDs for proper operation. The LED command must be set to ON (LEDS ON). After 16 seconds... The GP lamp should be lit continuously The DCD lamp should be lit continuouslyif synchronization with another unit has been achieved The Remote radio(s) should be transmitting data (TXD) and receiving data

. vi TransNET OEM Integration Guide MDS 05-xxxxA01, Rev. 01 1.0 ABOUT THIS MANUAL This manual is intended to guide technical personnel in the integration of MDS TransNET OEM transceivers into existing electronic equipment. The OEM transceiver is designed for use inside Remote Terminal Units (RTUs), Programmable Logic Controllers (PLCs) and other equipment associated with remote data collection, telemetry and control. The manual provides instructions for interface connections, hardware mounting, and programming commands. Following integration of the transceiver, it is recommended that a copy of this manual be retained for future reference by technical personnel. 2.0 PRODUCT DESCRIPTION The OEM transceiver, (Figure 1), is a compact, spread spectrum wireless module designed for license-free operation in the 2.4 GHz frequency range. It is contained on one double-sided circuit board with all necessary components and RF shielding included. It need only be protected from direct exposure to the weather and is designed for rugged service in extreme temperature environments. The transceiver has full over-the-air compatibility with standard (non-OEM) TransNET transceivers manufactured by MDS. TM All transceiver programming is performed via a connected PC terminal. No jumper settings or manual adjustments are used to configure the transceiver for operation. Invisible place holder Figure 1. TransNET OEM Transceiver The transceiver employs Digital Signal Processing (DSP) technology for highly reliable data communications, even in the presence of weak or interfering signals. DSP techniques also make it possible to obtain information about the radios operation and troubleshoot problems, often eliminating the need for site visits. Using appropriate software at the master station, diagnostic data can be retrieved for any radio in the system, even while payload data is being transmitted. (See Network-Wide Remote Diagnostics on Page 56.) MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 1 2.1 Transceiver Features The OEM transceiver is designed for easy installation and flexibility in a wide range of wireless applications. Listed below are several key features of the transceiver which are described in more detail later in this guide. Three operating bands in the 2.4006 to 2.4820 GHz spectrum Configurable operating zones to omit frequencies with constant interference 65,000 available network addresses to enhance communications security Network-wide configuration from the master station; eliminates most trips to remote sites Data transparencyensures compatibility with virtually all asynchronous data terminals Peak-hold RSSI, averaged over eight hop cycles Operation at up to 115,200 bps continuous data flow Store-and-Forward repeater operation Data latency typically less than 10 ms Same hardware for master or remote configuration Supports RS/EIA-232 or RS/EIA-485 interfaces (factory configured) Low current consumptionnominal 8 mA in sleep mode. Ideal for solar/battery powered applications. NOTE:

Some features may not be available on all units, based on the options pur-

chased and the regulatory constraints for the region in which the radio will op-

erate. 2.2 Model Configuration Codes The model number code is printed on the radio module, and provides key information about how it was configured when it left the factory. See Figure 2 for an explanation of the model number codes. (Note: This information is subject to change and should not be used for ordering additional products.

Model Number Configuration Codes 2.3 Spread Spectrum Transmission The transceiver hops from channel to channel many times per second using a specific hop pattern applied to all radios in the network. A distinct hopping pattern is provided for each of the 65,000 available network addresses, thereby minimizing the chance of interference with other spread spectrum systems. In the USA, and certain other countries, no license is required to install and operate this type of radio device, provided RF power and antenna gain restrictions are observed. In the USA and Canada, a maximum of 36 dBm Effective Isotropic Radiated Power (EIRP) is allowed. The factory offers a set of approved antennas with special connectors for this radio. Substitutions that would void the compliance of the device are not permitted. 2.4 Typical Applications Multiple Address Systems (MAS) This is the most common application of the transceiver. It consists of a central control station (master) and two or more associated remote units, as shown in Figure 3. This type of network provides communications between a central host computer and remote terminal units (RTUs) or other data collection devices. The operation of the radio system is transparent to the computer equipment. This application provides a practical alternative to traditional

(licensed) MAS radio systems.

Typical Point-to-Point Link 4 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Tail-End Link to an Existing Network A tail-end link is often used to extend the range of a traditional (licensed) MAS system without adding another licensed radio. This might be required if an outlying site is blocked from the MAS master station by a natural or man-made obstruction. In this arrangement, a spread spectrum transceiver links the outlying remote site into the rest of the system by sending data from that site to an associated transceiver installed at one of the licensed remote sitesusually the one closest to the outlying facility. (See Figure 5). As the data from the outlying site is received at the associated transceiver, it is transferred to the co-located licensed radio (via a data crossover cable) and is transmitted to the MAS master station over the licensed channel. Additional details for tail-end links are given in Section 7.2 (Page 25).

Typical Tail-End Link Arrangement Store-and-Forward Repeater Similar to a Tail-End Link, Store-and-Forward (SAF) offers a way to physically extend the range of a network, but in a simplified and economical manner. SAF operates by storing up the data received from one site, and then retransmitting it a short time later. Figure 6 shows a typical SAF repeater arrangement. SAF operates by dividing a network into a vertical hierarchy of two or more sub-networks. Extension radios (designated as

) serve as single-radio repeaters that link adjacent sub-networks, and move data from one sub-network to the next. Additional information on SAF mode is provided in Store & Forward (SAF) Operation with Extension Radios on Page 26.

Various Various 20-2822A01 Consult Factory 3.0 BENCHTOP SETUP & EVALUATION As an Integrator, your first task is to verify that the OEM module will function as intended with the host equipment. This section describes how to test the unit for operation with host devices such as RTUs, PLCs and similar gear. It covers the steps for making interface connections, powering up the transceiver, and setting configuration parameters using a connected PC. Evaluation of the module is best performed in a controlled environment, such as a shop or lab facility where you can readily test various hardware and programming configurations and observe the effects of these changes before final installation. Once you are satisfied that the transceiver module operates properly on the bench, you can plan the installation of the module inside the host device and be assured of proper operation in the field. 3.1 Evaluation Development Kit The Evaluation Development Kit is designed to assist integrators who will be working with the transceiver in a benchtop setting. The kit contains the following:

Two OEM Transceiver modules (configured for TTL, or RS-232/485 operation, as requested) Two Evaluation Development boards (P/N 03-4051A01) Interface Cables Two whip antennas Two 12 Vdc power supplies TransNET Support CD containing software for programming &

diagnostics MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 7

 

 

Evaluation Board A key part of the Evaluation Development Kit is the Evaluation Board shown in Figure 7. It contains a 16-pin header connector (J2) that mates with female connector J3 the OEM transceiver board. It carries all signals (except RF) onto the Evaluation Board. Table 2 lists the basic pin functions of J2. For more detailed pinout information, including the differences between TTL and RS-232/485 configured radios, refer to Section 13.1 on Page 60. The Evaluation Board provides convenient connection points for diagnostics, payload data, and DC power. Each of these connectors are discussed in this section. The board also includes a series of test probe points to the left of J2. These may be used for monitoring logic signal activity with a multimeter or oscilloscope. The probe points are identified by printed markings on the board. The transceiver boards RF/Antenna connection is Evaluation Board by the 16-pin header. The antenna connection is always made at J200 on the transceiver module using a male MMCX-type connector. brought onto the not STANDOFF SPACERS (4) 16-PIN HEADER TEST PROBE POINTS DC POWER

Diagnostic Connection (J4) J4 is an RJ-11-6 modular connector used to connect the evaluation board/transceiver to a PC terminal for programming and interrogation. An RJ-11 to DB-9 Adapter Cable (Part No. 03-3246A01) is required for this connection. If desired, an cable may be constructed for this purpose as shown in Figure 10. Only Pins 4, 5, and 6 of the RJ-11 connector should be used. Pins 1, 2, and 3 are reserved for factory test purposes.) The data parameters of the diagnostics port are as follows: 8 data bits, 1 stop bit, and no parity. It automatically configures itself to function at 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps, as required. Invisible place holder RJ-11 PLUG

(A pre-constructed cable is also available, Part No. 03-3246A01) Diagnostic Communication Modes Two methods may be used to communicate with the radios diagnostic port:

The PC is used in its basic terminal emulation Terminal Interface mode, (i.e., HyperTerminal session) and commands are issued as simple text strings. Radio Configuration Software Proprietary software from MDS that runs under the Windows operating system. It provides a graphical user interface with point and click functionality. The program is included on the CD shipped with every radio order. Both of these control methods are described in more detail in the section titled PROGRAMMING REFERENCE on Page 34. This section also includes a chart listing all commands for the OEM transceiver. TransNET Support Package MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 11 Data Connector (J5) J5 on the Evaluation Board (Figure 11) is the data interface for the transceiver. It is used to connect the transceiver to an external DTE terminal that supports the EIA/RS-232 or EIA/RS-485 format, depending on how the radio hardware was configured at the factory. The data connector supports interface data rates of 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps (asynchronous only). The connector mates with a standard DB-9 plug available from many electronics parts suppliers. Data Wiring Connections The connections made to J5 will depend on the requirements of the DTE device being used with the transceiver, and the operating functions that you require. Only the required pins for the application should be used. Do not use a straight through computer type cable that is wired pin-for-pin. Typical RS/EIA-232 applications require the use of Pin 2 (receive dataRXD) and Pin 3 (transmit dataTXD). Additionally, some systems may require the use of Pin 7 (Request-to-sendRTS).

(Consult external device manual for its detailed pin information) DC Power Connector (J3) This connector accepts operating power for the transceiver. A wall-style AC adapter (Part No. 01-3862A02) is recommended for this service. DC connection is made with a 2-pin polarized plug, MDS Part No. 73-1194A39. Be sure to observe proper polarity. The left terminal is positive (+) and the right is negative (-). (See Figure 13). 14 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 CAUTION POSSIBLE EQUIPMENT DAMAGE The transceiver must be used only with negative-ground systems. Make certain that the polarity of the power source is correct. Invisible place holder Lead Binding Screws (2) Wire Ports (2)

(Polarity: Left +, Right ) Retaining Screws (2) Figure 13. DC Power Connector (P/N 73-1194A39) NOTE: Although the power connector used on the OEM Evaluation Board resembles those used by some earlier MDS transceivers, such as the MDS 9810 and x710 family, the connectors are not equal and the use of the wrong plug will provide unreliable connections. Only the power connector shown in Figure 13 with screw terminals and two retainer screws should be used with the OEM Evaluation Board. Jumper Block J1 (DC Power Configuration) Jumper J1 does not normally require any change by the user. The jumper is used to configure the board for the proper voltage level applied to the transceiver module. Both jumper plugs are normally installed on J1. The plug connecting Pins 3 and 4 may be temporarily removed to insert an ammeter in series with the DC power line going to the transceiver. This provides a convenient way to measure the transceivers current draw during bench testing. Initial Power-Up & Configuration 3.3 When all of the cable connections described in Section 3.2 have been made, the transceiver is ready for initial power-up. Operation begins as soon as power is applied, and there are no manual adjustments or settings required. To place the transceiver into operation:

1. Ensure that all cable connections are properly wired and secure. Verify that no metallic objects are touching the underside of the evaluation board which might cause a short-circuit. 2. Apply DC power. The GP indicator (CR6) on the transceiver board should light continuously. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 15 3. Using a connected PC terminal, congure the unit with the proper mode

(master or remote), network address and data parameters. See Configuration Settings below for programming details. 4. Observe the transceivers LED indicators for proper operation. Table 5 on Page 17 shows the functions and normal indications of the LEDs. 5. Verify that the transceiver is transmitting and receiving data (TXD, RXD) in response to the master station and/or connected terminal device. Configuration Settings This section explains how to set the essential operating parameters of the transceiver. For more information on connecting a PC terminal and preparing it for use, refer to Section see PROGRAMMING REFERENCE on Page 34. The three essential settings for the transceiver are as follows:

ModeMaster, Remote, or Extension Network Addressa unique number from 165000 Data Interface Parametersbps, data bits, parity, stop bits Bandset transceiver to one of its three operating bands

(A, B or C) Follow these steps to program the transceiver:

1. Set the Mode using the MODE M (Master), MODE R (Remote), or MODE X

(Extension) command. (Note: There can be only one master radio in a system.) For Extension (SAF) radios only: If any MODE X radios are used in the network, SAF must be turned on at the Master station. The MODE X radio must be programmed with an Extended Address (XADDR). Units that need to hear the MODE X radio must be programmed with an appropriate XPRI and/or XMAP value. (See Simple Extended SAF Network on Page 26 for more information.) 2. Set a unique Network Address (165000) using ADDR command. Each radio in the system must have the same network address. Tip: Use the last four digits of the master stations serial number to help avoid conicts with other users. 3. Set the baud rate/data interface parameters. Default setting is 9600 bps, 8 data bits, no parity, 1 stop bit. If changes are required, use the BAUD xxxxx abc command where xxxxx equals the data speed (1200115200 bps) and abc equals the communication parameters as follows:

a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even) c = Stop bits (1 or 2) NOTE: 7N1, 8E2 and 8O2 are invalid interface parameters. 16 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Configuring Multiple Remote Units In most installations, the Remote radios will be programmed with virtually the same set of parameters. This process can be streamlined by testing key pieces of equipmentsuch as the Master, Remote, and any Extensionson a benchtop setup prior to installation. This allows you to test various configurations in a controlled environment. Once the evaluation network is working satisfactorily, you can save the configuration of each unit in a data file on your PCs hard drive through the use of TransNET Configuration Software. You can then open the Remote configuration file and install it in the next Remote radio. The software prevents you from overwriting unit or other mode-specific parameters. LED Indicators The LED indicators are located to the right of the transceivers shield cover

(near J3) and show important information about status of the module. The functions of LEDs are explained in Table 5 below. NOTE: For the LEDs to function, they must be enabled using the LEDS ON command. Within 16 seconds of power-up, the following indications will be seen if the unit has been properly configured and is communicating with another transceiver:

The module need only be protected from direct exposure to the weather. No additional RF shielding is required. 5.1 Mounting Dimensions Figure 15 shows the dimensions of the transceiver board and its mounting holes. If possible, choose a mounting location that provides an unobstructed view of the radios LED status indicators when viewing the board from outside the host device. Mount the transceiver module to a stable surface using the four mounting holes at the corners of the PC board. Standoff spacers should be used to maintain adequate clearance between the bottom of the circuit board and the mounting surface. (Fasteners/anchors are not normally supplied.) 1.81

Contact your factory representative for specific recommendations on antenna types and hardware sources. In general, an omnidirectional antenna (Figure 16) is used at master station sites in order to provide equal coverage to all of the remote units. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 21 At remote sites and in many point-to-point systems, a directional Yagi antenna (Figure 17) is generally recommended to minimize interference to and from other users and to maximize range. For systems operating in a very short range environment, small, flexible whip antennas may also be supplied. Such antennas are available for direct connection to the transceiver module, or for exterior mounting with various lengths of feedline. Figure 16. Omnidirectional Antenna

(shown mounted to mast) Invisible place holder Figure 17. Typical Yagi Antenna (shown mounted to mast) Feedlines The feedline supplied with the antenna was carefully selected to minimize RF loss and ensure regulatory compliance with the antenna being used. Do not make substitutions or change the lengths of the antenna system feedline. If you require a different length of feedline for your installation, contact your factory representative for assistance. NOTE: Strong fields near the antenna can interfere with the operation of the low level RTU circuits and change the reported values of the data being monitored. If in-

terference is experienced, it may be necessary to re-orient the antenna with re-

spect to the radio, RTU, sensors or other components of the system. 22 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 6.0 EIRP Compliance Check IMPORTANT: To comply with FCC and Industry Canada rules, the effective isotropic radiated power (EIRP) of an OEM transceiver installation must not exceed 36 dBm. Transceiver modules are shipped from the factory with an RF output setting of +27 dBm. This setting is password-controlled and may not be changed by unauthorized persons. This power level provides EIRP compliance when the module is used with many types of antennas, however, each installation must be carefully evaluated to ensure compliance. The formula for determining EIRP is as follows:

Transmitter RF output power (dBm) + Antenna gain (dBi) Feedline loss (dB) Table 7 shows three types of antennas and their associated gains. Note that for a 10 dBi gain antenna, the system must include at least 1 dB of feedline loss to achieve EIRP compliance. Higher gain antennas would require additional feedline loss in order to limit the EIRP to a maximum of 36 dBm. If no feedline is used (directly connected antenna), with an antenna gain exceeding 9 dBi, it will be necessary to reduce the transmitter output power to less than +27 dBm. Contact MDS for further information. In no case shall the stations EIRP exceed 36 dBm. Table 7. Antenna System Gain vs. EIRP Antenna Type

The effectiveness of these techniques will vary with the design of your system and the format of the data being sent. Complete instructions for using the commands referenced in this manual are provided in PROGRAMMING REFERENCE on Page 34. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 23 7.1 Antenna Aiming For optimum performance of directional antennas (yagis), they must be accurately aimed in the direction of desired transmission. The easiest way to do this is to point the antenna in the approximate direction, then use the remote radios RSSI command (Received Signal Strength Indicator) to further refine the heading for maximum received signal strength. In an MAS system, RSSI readings are only meaningful when initiated from a remote station. This is because the master station typically receives signals from several remote sites, and the RSSI would be continually changing as the master receives from each remote in turn. 7.2 Antenna SWR Check It is necessary to briefly key the transmitter for this check by placing the radio in the SETUP mode (Page 49) and using the KEY command. (To unkey the radio, enter DKEY; to disable the SETUP mode and return the radio to normal operation, enter Q or QUIT.) The SWR of the antenna system should be checked before the radio is put into regular service. For accurate readings, a wattmeter suited for 2.4 GHz is required. One unit meeting this criteria is the Bird Model 43 directional wattmeter with an appropriate element installed. The reflected power should be less than 10% of the forward power (2:1 SWR). Higher readings usually indicate problems with the antenna, feedline or coaxial connectors. 7.3 Data Buffer Setting The default setting for the data buffer is OFF. This allows the radio to operate with the lowest possible latency and improves channel efficiency. MODBUS and its derivatives are the only protocols that should require the buffer to be turned on. See BUFF [ON, OFF] on Page 42 for details. 7.4 Hoptime Setting The default hop-time setting is 7 (7 ms). An alternate setting of 28 is used to increase throughput, but at the cost of increased latency. A detailed explanation of the HOPTIME command can be found on Page 44. 7.5 Operation at 115200 bps Burst throughput at 115200 bps is supported at all settings. The radio will always buffer at least 500 characters. Sustained throughput at 115200bps is only possible when the data path is nearly error free and the operating settings have been properly selected. For sustained operation at 115200 bps, use the following settings: SAF OFF, FEC OFF, REPEAT 0, RETRY 0, HOPTIME 28. 24 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 7.6 Baud Rate Setting The default baud rate setting is 19200 bps to accommodate most systems. If your system will use a different data rate, you should change the radios data interface speed using the BAUD xxxxx abc command (Page 42). It should be set to the highest speed that can be sent by the data equipment in the system.

(The transceiver supports 1200 to 115200 bps.) 7.7 Radio Interference Checks The radio operates in eight frequency zones. If interference is found in one or more of these zones, the SKIP command (Page 49) can be used to omit them from the hop pattern. You should also review 8.0 DEALING WITH INTERFERENCE, when interference problems are encountered. 8.0 OPERATING PRINCIPLES & SPECIAL CONFIGURATIONS 8.1 How Remotes Acquire Synchronization Remotes acquire synchronization and configuration information via SYNC messages sent from the Master (the MODE M unit) or from any valid Extension (MODE X unit). The Master will always transmit SYNC messages. An Extension will only start sending SYNC messages after synchronization is achieved with its Master. The ability to synchronize to a given radio is further qualified by the senders Extended Address (XADDR) and by receivers Synchronization Qualifiers

(XMAP, XPRI, and XRSSI). When a primary is specified (XPRI is 0...31), a radio will always attempt to find the primary first. If 30 seconds elapses and the primary is not found, then the radio will attempt to synchronize with any non-primary radio in the XMAP list. Once every 30 minutes, if a primary is defined, the radio will check its synchronization source. If the radio is synchronized to a unit other than the primary, then the current RSSI value is compared to the XRSSI value. If RSSI is less than XRSSI (or if XRSSI is NONE) the radio will force a loss-of-synchronization, and hunt for the primary again (as described in the previous paragraph). By default, Extensions (and the Master) begin with XADDR 0. Synchronization qualifiers are set to XMAP 0, XPRI 0, and XRSSI NONE, respectively. This default configuration allows any radio to hear the Master. When an Extension is added, the extended address of the Extension must be set to a unique value. All remotes that need to hear that extension can specify this either by designating the extension as the primary (XPRI), or by including it in their list of valid synchronization sources (XMAP). MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 25 8.2 Establishing a Tail-End Link A tail-end link can be used to bring an outlying remote site into the rest of an MAS network. Figure 5 on Page 5 shows a diagram of this type of system. A tail-end link is established by connecting an OEM transceiver back-to-back with another unit such as a licensed MDS x710 Series transceiver. The wiring connections between the two radios must be made as shown in Figure 18. In addition, the DEVICE CTS KEY command must be asserted at the OEM radio. r e v i s e i r e S 0 1 7 x S D M e c s n a r T e t o m e R

Figure 18. Data Crossover Cable for Tail-End Links 8.3 Store & Forward (SAF) Operation with Extension Radios The Store-and-Forward (SAF) capability allows individual radios to act as data repeaters. SAF operates by dividing a network into a vertical hierarchy of two or more sub-networks. (See Figure 6 on Page 6.) Adjacent sub-networks are connected via Extension radios operating in MODE X which move data from one sub-network to the next one. The Store-and-Forward implementation adheres to the general polling principles used in most multiple-address systems (MAS). Polls originate from the Master station, broadcast to all radios within the network, and travel hierarchically downward. All Remotes will hear the same message, but only one Remote will respond. Messages within a hierarchy only travel in one direction at a time. Using SAF will cut the overall data throughput in half, however, multiple networks can be inter-connected with no additional loss in network throughput. 26 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Simple Extended SAF Network Figure 19 depicts a two-level network utilizing a single Master (M) and an Extension (X) radio. In this network, messages directed to Remotes in the K sub-network, will be relayed through Extension radio Xj,k to the K-Remotes. Any response from a Remote in sub-network K will pass back through Extension radio Xj,k to the Master Mj. Radios in sub-network J operate on the same set of frequencies and sub-network K but with a different radio-frequency hopping pattern.

Extended SAF Network Below is an example of a multilevel network utilizing two repeatersXJ,K and XK,L. The example demonstrates the extensibility of the network. In this case, messages directed to Remotes in the sub-network L will be relayed through Extension radios XJ,K and XK,L. As in the previous example, the Extension radios will split their operating time equally between their Master and Remote personalities. This multi-layered network can be extended indefinitely without degrading system throughput beyond that initially incurred by placing the network in the SAF mode.

Extended SAF Network Networks: J, K, L Retransmission and ARQ operation Functionally, the sub-network side of an Extension behaves like a corresponding connection between a master and a remote. When an Extension is using its master personality it sends acknowledgments and performs unconditional retransmissions based on its REPEAT count. When an Extension is using its Remote personality, acknowledgments are processed and retransmissions occur as needed, up to the number of times specified by the RETRY count value. If new data arrivesfrom a new sourceprior to completion of retransmissions, then this is considered a violation of the polling model protocol. The new data takes precedence over the old data and the old data is lost. In such a situation, new data is likely to be corrupt as it will have some old data mixed in with it. Synchronization in SAF Networks The Master controls the synchronization for a given network for all modes. Setting the Master to SAF ON broadcasts a command from the Master to all radio units in the associated network either directly or through an Extension radio. This command puts all radios in the entire system in a special time-division duplexing mode that alternates between two timeslots. One time slot for data communications upstream and another for downstream communications. 28 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 The Extensions are single radios which serve as bridges between adjacent sub-network levels. Extensions will undertake a remote personality in one timeslot, and a master personality in the alternate timeslot and provide communications with associated Remotes downstream. Extensions behave like two radios with their data ports tied together, first synchronizing with their upstream Master during their Remote personality period, and then providing synchronization signals to dependent Remotes downstream during its Master personality period. All Remotes synchronize to a corresponding Master. This can be the real master (the MODE M unit), or it can be a repeater Extension that derives synchronization from the real master. Payload polls/packets broadcast from the network Master will be repeated to all levels of the network, either directly to Remotes, or through network repeatersthe Extensions station. The targeted Remote will respond to the poll following the same path back to the Master. Configuration Parameters for Store-and Forward Services The installation and configuration of a network with an Extension using SAF is straight-forward with only a few unique parameters that need to be considered and set at each unit. In every network there can be only one Master station. It will serve as the sole gateway to the outside world.

(Ineffective when XPRI is NONE) 8.4 Sleep Mode Operation (Remote units only) In some installations, such as at solar-powered sites, it may be necessary to keep the transceivers power consumption to an absolute minimum. This can be accomplished using the radios Sleep Mode feature. In this mode, power consumption is reduced to about 8 mA. Sleep Mode can be enabled under RTU control by asserting a ground (on Pin 6 of J3, the radios header connector. The radio stays in Sleep Mode until the low is removed, and all normal functions are suspended. The radio can be awakened by your RTU every minute or so to verify synchronization with the master station. When the ground is removed, the radio will be ready to receive data within 75 milliseconds. NOTE: The SLEEP function must be set to ON; otherwise a ground on the Sleep Mode pin will be ignored. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 31 It is important to note that power consumption will increase somewhat as communication from the master station degrades. This is because the radio will spend a greater period of time awake looking for synchronization messages from the master radio. In order for the radio to be controlled by the Sleep Mode pin, the radio must be set to SLEEP ON. See SLEEP [ON, OFF] on Page 50 for more information. Sleep Mode Example The following example describes Sleep Mode implementation in a typical system. Using this information, you should be able to configure a system that meets your own particular needs. Suppose you need communications to each remote site only once per hour. Program the RTU to raise an EIA/RS-232 line once each hour (DTR for example) and wait for a poll and response before lowering it again. Connect this line to Pin 6 of the radios header connector. This will allow each RTU to be polled once per hour, with a significant savings in power consumption. 9.0 DEALING WITH INTERFERENCE The transceiver shares the frequency spectrum with other services and other Part 15 (unlicensed) devices in the USA. As such, near 100% error free communications may not be achieved in a given location, and some level of interference should be expected. However, the radios flexible design and hopping techniques should allow adequate performance as long as care is taken in choosing a suitable location and in configuring the radios operating parameters. In general, keep the following points in mind when setting up your communications network:

1. Systems installed in rural areas are least likely to encounter interference;

those in suburban and urban environments are more likely to be affected by other devices operating in the license-free frequency band and by adjacent licensed services. 2. If possible, use a directional antenna at remote sites. They conne the transmission and reception pattern to a narrow lobe, which minimizes interference to (and from) stations located outside the pattern. 3. If interference is suspected from a nearby licensed system (such as a paging transmitter), it may be helpful to use horizontal polarization of all antennas in the network. Because most other services typically use vertical polarization in this band, an additional 20 dB of attenuation to interference can be achieved by using the horizontal plane. 4. Multiple spread spectrum systems can co-exist in close proximity to each other with only minor interference, provided they are each assigned a unique network address. Each network address has a different hop pattern associated with it. 32 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01

 

 

5. If constant interference is present in a particular frequency zone, it may be necessary to lock out that zone from the radios hopping pattern. The radio includes built-in tools to help users do this. Refer to the discussion of the SKIP command (Page 49) for more information. In the USA, a maximum of four zones may be skipped, per FCC rules. Check the regulatory requirements for your region. 6. Interference can also come from out-of-band RF sources such as paging systems. Installation of a bandpass filter, such as Part No. 20-2822A02 in the antenna system may provide relief from this type of interference. 7. Proper use of the RETRY and REPEAT commands may be helpful in areas with heavy interference. The RETRY command sets the maximum number of times (1 to 10) that a radio will re-transmit upstream data over the air. Values greater than 1 successively improve the chances of a message getting through when interference is a problem. The REPEAT command sets a xed number of unconditional retransmissions for downstream data. 8. The RF power output of all radios in a system should be set for the lowest level necessary for reliable communications. This lessens the chance of causing unnecessary interference to nearby systems and keeps power consumption to a minimum. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 33 10.0 PROGRAMMING REFERENCE All programming and control of the transceiver is performed through a PC terminal connected to the radio or the Evaluation Board DIAG connector. There are no manual adjustments or jumper settings used for configuration. This section explains how to establish terminal communication, and provides a complete list of user commands. 10.1 Programming Methods Terminal Interface Mode A PC may be used by operating it in a basic terminal mode (e.g., a HyperTerminal session) and entering the radio commands listed in the tables contained in this section. The PC must be connected to the radio via its 16-pin header connector, or, if using the Evaluation Board, via the modular diagnostics connector. In the latter case, an RJ-11 to DB-9 Adapter Cable

(Part No. 03-3246A01) is required. A cable of this type may be constructed using the information shown in Figure 10 on Page 11. Once a PC terminal is connected, communication (baud rate) is automatically established through the command interface. To access the command interface, press the ESCAPE key, followed by one or more ENTER keystrokes

(delivered at about half-second intervals), until the > prompt is displayed. NOTE: The diagnostic interface uses 8 data bits, 1 stop bit, and no parity. It automati-

cally configures itself to function at 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps. If the DLINK setting is ON, the interface will start out in Diagnostic Link mode. This is a special protocol used to support Network-Wide Diagnostics. The pro-

cess described in the paragraph above causes the radio to exit diagnostic link mode and enter command mode. If there is no input in command mode for 5 minutes, the interface will revert back to diagnostic link mode. PC-Based Configuration Software The Windows-based TransNET Configuration Software

(P/N 06-4059A01) is designed for use with the OEM Transceiver. This software provides access to all of the radios capabilities with the benefit of context-sensitive help. The program is shipped as part of the TransNET Support Package CD included with every order. 10.2 User Commands A series of tables begin on the next page listing the various user commands for the OEM transceiver. The tables provide abbreviated command descriptions.

However, proper use of the additional commands allows you to tailor the transceiver for a specific use, or to conduct basic diagnostics on the radio. This section gives more detailed information for the commands listed above in section 9.2. Most of the commands below can be used in two ways. First, you can type only the command name (for example, ADDR) to view the currently programmed data. Second, you can set or change the existing data by typing the command, followed by a space, and then the desired entry (for example, ADDR 1234). In the list below, allowable programming variables, if any, are shown in brackets [ ] following the command name. ADDR [165000]

This command sets or displays the radios network address. The network address can range from 1 to 65000. A network address must be programmed at the time of installation and must be common across each radio in a given network. Radios are typically shipped with the network address unprogrammed, causing the address to display as NONE. If the address is not set (or is set to a wrong value) it leaves the system in an invalid state, preventing operation and generating an alarm. NOTE: It is recommended that the last four digits of the master radios serial number be used for the network address. This helps avoid conflicts with other users. 40 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 AMASK [0000 0000FFFF FFFF]

This command sets the alarm bits that cause the alarm output signal to be triggered. The PWR LED will still flash for all alarms, but the alarm output signal will only be activated for those alarms that have the corresponding mask bit set. The hex value for the mask aligns directly with the hex value for the ALARM command. The default is FFFF FFFF. Through proper use of the AMASK command, it is possible to tailor the alarm response of the radio. Contact the factory for more information on configuring the alarm mask. ASENSE [HI/LO]

This command is used to set the sense of the radios alarm output at Pin 3 of the 16-pin header connector. The default setting is HI which means an alarm exists when an RS-232 high is on Pin 3. BAND [abc]

The BAND command is used to select one of three frequency ranges that the transceiver will operate in (A, B, or C). All transceivers in a given network must have the same band setting or communication will not be possible. Conversely, radios may be set to different bands to enable up to three separate radio networks to operate in the same vicinity, without cross-network interference. Each frequency band is approximately 26 MHz wide, and contains eight zones within. These zones are described in more detail under the ZONE DATA command (see Page 51). The frequency ranges for each band are as follows:

Band A: 2.40162.4270 GHz Band B: 2.42722.4526 GHz Band C: 2.45282.478.2 GHz BAUD [xxxxx abc]

This command sets or displays the communication attributes for the normal payload communications through the DATA port. The command has no effect on the RJ-11 DIAG(NOSTICS) port. The first parameter (xxxxx) is baud rate. Baud rate is specified in bits-per-second and must be one of the following speeds: 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200. At baud rates of 19200 bps or less, the radio can support unlimited continuous data transmission at any hop rate. The second parameter of the BAUD command (abc) is a 3-character block indicating how the data is encoded. The following is a breakdown of each characters meaning:

a = Data bits (7 or 8) b = Parity (N for None, O for Odd, E for Even) c = Stop bits (1 or 2) The factory default setting is 9600 baud, 8 data bits, no parity, 1 stop bit

(Example: 19200 8N1). MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 41 NOTE: 7N1, 8O2, and 8E2 are invalid communication settings and are not supported by the transceiver. BUFF [ON, OFF]

This command sets or displays the received data handling mode of the radio. The command parameter is either ON or OFF. (The default is OFF.) The setting of this parameter affects the timing of received data sent out the DATA connector. Data transmitted over the air by the radio is unaffected by the BUFF setting. If data buffering is set to OFF, the radio will operate with the lowest possible average latency. Data bytes are sent out the DATA port as soon as an incoming RF data frame is processed. Average and typical latency will both be below 10 ms, but idle character gaps may be introduced into the outgoing data flow. If data buffering is ON, the radio will operate in a seamless mode. That is, data bytes will be sent over the air as quickly as possible, but the receiver will buffer the data until the entire packet has been collected. The delay introduced by data buffering is variable and depends on message size and the number of retransmissions required, but the radio will not create any gaps in the output data stream. This mode of operation is required for protocols such as MODBUS that do not allow gaps in their data transmission. Seamless mode (BUFF ON) is intended only for applications where the message size is 256 characters or less. Enforcement of this rule is left up to the user. If more than 256 characters are transmitted data delivery will not be seamless and data may be lost. Changes to the BUFF setting may only be made at the master radio. This is because the master radio broadcasts the buffer setting for the entire network. At remote radios, the buffer setting may be read when the radio is in synchronization with the master, but it may not be changed. CODE [NONE, 1255]

The CODE command is used to select or display the security/encryption setting in the radio. The default is CODE NONE. Setting CODE to a value other than NONE provides an extra level security beyond that provided by the Network Address

(ADDR). The disadvantage is increased complexity in managing the network. The CODE command takes an argument 1255, or NONE. Entering CODE without an argument will display either NONE or ACTIVE. ACTIVE means that security/encryption has been enabled, but the radio will not display the security argument. When a CODE value is active, all radios in the system must use the same code value. If the code value is not properly programmed, a remote radio will not synchronize with the master. CAUTION: Record the CODE value and store it in a safe place. If the code is later forgotten, and a unit is to be added to the system, all radios in the network must be set to NONE and then reprogrammed to a new value. 42 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 CTS [0255]

The CTS (clear-to-send) command sets or displays the timer value associated with the CTS line response. The command parameter ranges from 0 to 255 milliseconds. For DCE operation, the timer specifies how long to wait after the RTS line goes high before asserting the CTS line. A timer value of zero means that the CTS line will be asserted immediately following the assertion of RTS. For CTS Key operation (see the DEVICE command), the timer specifies how long to wait after asserting the CTS line before sending data out the DATA port. A timer value of zero means that data will be sent out the data port without imposing a key-up delay. (Other delays may be in effect from other radio operating parameters.) CTSHOLD [060000]

Used in DEVICE CTS KEY mode, this command sets the amount of time in milliseconds that CTS remains present following transmission of the last character out the RXD pin of the DATA port. This hold time can be used to prevent squelch tail data corruption when communicating with other radios. The CTSHOLD setting can range from 0 to 60000 (i.e., 60 seconds). The default value is 0, which means that CTS will drop immediately after the last character is transmitted. If the command is entered when the radio is in DEVICE DCE mode, the response CTSHOLD N/A will be displayed. DEVICE [DCE, CTS KEY]

The DEVICE command sets or displays the device behavior of the radio. The command parameter is either DCE or CTS KEY. The default selection is DCE. In this mode, CTS will go high following RTS, subject to the CTS programmable delay time. Keying is stimulated by the input of characters at the data port. Hardware flow control is implemented by dropping the CTS line if data arrives faster than it can be transmitted. If CTS KEY is selected, the radio is assumed to be controlling another radio, such as in a repeater or tail-end link system. The RTS line is ignored and the CTS line is used as a keyline control for the other radio. CTS is asserted immediately after the receipt of RF data, but data will not be sent out the DATA port until after the CTS programmable delay time has expired. (This gives the other radio time to key.) Following transmission of the last byte of data, CTS will remain asserted for the duration specified by the CTSHOLD command. CTSHOLD should be set sufficiently high. DLINK [xxxxx/ON/OFF]

DLINK ON enables use of Diagnostic Link mode and establishes it as the default protocol on the RJ-11 DIAG port. Diagnostic Link mode is a special protocol used to support Network-Wide Diagnostics. DLINK must be set to ON to support connection to InSite or to support chained diagnostics between radio networks. DLINK OFF disables this feature. The default setting is ON. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 43 The following DLINK baud rates selections are allowed:

19200 (default) 1200 38400 4800 57600 9600 115200 Example: DLINK 4800 sets the RJ-11 DIAG port to operate at 4800 bps when diagnostics is closed. This setting will not affect the ports autobaud operation. Use only of DLINK ON, will enable the use 19200 or the most recently programmed value. The default is DLINK 19200 and DLINK ON. NOTE: The same baud rate must be entered into the InSite Equipment Lists BAUD field. NOTE: The DLINK rate must match the rate of any connected device to the diagnostic port. This may be either another radios diagnostic port, the InSite computer, or another data link device that eventually connects to the InSite computer. DKEY Disables the transmitter when it is keyed. See also KEY command. DTYPE [NODE/ROOT]

The DTYPE command specifies the radios operational characteristics for network-wide diagnostics. The transceiver uses the following types:

NODEThe most common setting, and the default. This is the basic system radio device-type. Typically, the radio network is comprised of nodes and one root. Intrusive diagnostics can originate from any node. However, non-intrusive diagnostics can only be conducted from the root node. ROOTAlways one, and only one, per network (including units associated through Extension units.) The root is the focal point of network-wide diagnostics information. Intrusive diagnostics can originate from any radio, including the root. However, the root is the only radio through which non-intrusive diagnostics can be conducted. FEC [ON, OFF]

This command is used to view the FEC setting, or turn it on or off. The default setting is FEC ON. (It needs to be turned off when throughputs exceed 57,600 bps.) FEC is set at the master and is automatically passed on to all of the remotes in a network. Setting FEC to ON improves sensitivity at the cost of reduced throughput. Typical SCADA/telemetry applications use low data rates and, as such, the FEC setting is normally transparent to them. HOPTIME [7, 28]

The HOPTIME command is used to set or display the hop-time setting. The command is a digit corresponding to the hop-time setting in milliseconds. The default HOPTIME setting is 7. A setting of 28 must be used when throughputs exceed 57,600 bps. 44 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Changes to the HOPTIME setting may only be made at the master radio. (This is because the Master radio establishes the hop-time setting for the entire network.) At remote radios, the hop-time setting may be read when the radio is in synchronization with the master, but it may not be changed. INIT The INIT command is used to reset the radios operating parameters to the factory defaults listed in Table 16 on Page 46. This may be helpful when trying to resolve configuration problems that resulted from the entry of one or more improper command settings. If you are unsure of which command setting caused the problem, this command allows you to get back to a known working state. NOTE: Caution should be exercised when using the INIT command on radios in a sys-

tem employing the Store-and-Forward feature. Settings relating to the use of Extension services will be lost and will need to be re-entered. Inventory and record the settings for XADDR, XPRI and XMAP before using the INIT com-

mand. SPECIAL NOTE: Installing firmware of Revision 2.0 or later into a radio with Revi-

sions 1.x firmware will preserve the radios compatibility with other radios run-

ning Revision 1.x firmware. If updating the radios firmware is part of a system-wide upgrade, the last step should be to use the INIT command at the Master station. Use of the INIT command causes the changes shown in Table 16 on Page 46 to be applied HREV Shows the Hardware revision of the radio. KEY Enables the transmitter. (Radio must be in Setup mode.) See also DKEY command. LEDS [ON, OFF]

This command is used to view the LED setting, or to enable/disable LED operation. In power-critical applications (battery/solar powered sites, for example), it may be desirable to turn off the LEDs. MODE [M, R, X]

The MODE command sets or displays the operating mode of the radio. A master radio is set by MODE M; a remote set by MODE R, and an Extension is set by MODE X. All units default to remotes; other modes must be specifically programmed with the MODE command. If MODE X is used, the MODE X radio should be programmed with an Extended Address (XADDR). Units that need to hear this MODE X radio must be programmed with an appropriate XPRI and/or XMAP value. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 45 OWM [xxxxx]

The OWM command sets or displays an optional owners message, such as the system name. The entry can contain up to 30 characters. OWN [xxxxx]

The OWN command sets or displays an optional owners name, such as the site name. The entry can contain up to 30 characters. PORT [RS232, RS485]

Select or identify the current data interface signaling mode: RS232 or RS485. This is the port though which the payload data will pass. Pin descriptions for EIA-232 are on Page13 and EIA-485 can be found on Page13. Note: This command will always show TTL if the radio is only equipped for TTL servicesee model number configuration code on Page 3. PWR [1721]

This command displays or sets the desired RF forward output power setting of the radio. The PWR command parameter is specified in dBm and can range from 20 dBm through 27 in 1 dBm steps. The default setting is 27 dBm (0.5 watt). To read the actual (measured) power output of the radio, use the SHOW PWR command. In the USA, maximum allowable power is governed by FCC limits on Effective Isotropic Radiated Power output (EIRP). The EIRP limit of

+36 dBm means that any user with a net antenna gain greater than 10 dBi must decrease the PWR setting accordingly. Table 16.

The REPEAT command affects downstream data. The command causes a Master or Extension to always repeat transmissions for the specified number of times (range is 0 to 10; default selection is 3). Unlike the RETRY command, there is no acknowledgment that a message has been received. To display the current setting, use the REPEAT command without entering a value. RETRY [010]

The RETRY command affects upstream data. The command selects, or displays, the maximum number of times (0 to 10) that a remote radio will re-transmit data. The default setting is 10. This command is associated with ARQ (Automatic Repeat Request) operation of the radio and is intended for use in areas with heavy radio interference. When the RETRY command is issued without parameters, the maximum retransmission count is shown. A value of 0 represents no retries, while values of 1 or greater successively improve the chance of data delivery in spectrally harsh environments (at the expense of possibly increased latency). The RETRY value is only settable at the Master. It is readable by a synchronized Remote. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 47 RSSI This command displays the radios Received Signal Strength Indication in dBm (decibels relative to 1 mW). The output can range from 40 dBm to 120 dBm. Command availability and results depend on the mode of operation (master or remote). The closer to 0 dBm, the stronger the signal, thus a reading of 70 dBm is stronger than 80 dBm. For a remote radio, under normal operation, RSSI is based on the average signal strength of the SYNC message received in each of the eight frequency zones. (RSSI is sampled each time a SYNC message is received.) When using the RSSI reading to align a directional antenna, it is important to make changes slowly so that the RSSI reading will provide meaningful results. It will take several seconds to indicate a change in signal level. The radio stays in RSSI mode until For a master radio, under normal operation, entering the RSSI command causes the response NOT AVAILABLE to be returned. This is because a master is normally receiving signals from several remote stations and an RSSI reading would be continually changing. The only exception is when the SETUP command has been asserted. This disables hopping and allows reading a raw RSSI signal level in real time from a master or remote radio. is pressed. ENTER NOTE: RSSI readings will not indicate signals stronger than 40 dBm. RTU [ON, OFF, 0-80]

This command re-enables or disables the radios internal RTU simulator, which runs with proprietary polling programs such as poll.exe and rsim.exe. The internal RTU simulator is available whenever a radio has diagnostics enabled. This command also sets the RTU address that the radio will respond to. The internal RTU can be used for testing system payload data or pseudo bit error rate (BER) testing. It can be helpful in isolating a problem to either the external RTU or the radio. The default RTU setting is OFF. RX [xxxx]

This command sets or displays the test receive frequency used in place of hopping when the radio is in SETUP mode. The test receive frequency can be reprogrammed to any value between 2.4016 GHz and 2.4782 GHz, inclusive. The factory default setting is 2.42420 GHz. RXTOT [NONE, 01440]

This command sets or displays the amount of time (in minutes) to wait for the next received data packet before issuing a receiver time-out alarm. The default setting is NONE. 48 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 SAF [ON, OFF]

This command enables/disables the operation of the Store-and-Forward services. It can be set only at the networks Master station, but will effect all radios in the associated network. The default setting is OFF. See related commands: XADDR [031] on Page 51, XPRI [031] on Page 51, and XMAP [00000000-FFFFFFFF] on Page 51. SETUP This command sets up the transceiver for checking antenna SWR or trans-

mitter power with external measuring equipment. Do not use this mode during normal operation. When the SETUP command is entered, the prompt changes to SETUP>, and:

Hopping is disabled. Synthesizer frequencies are reset to the test frequencies specified by the TX and RX commands described earlier. The radio can be keyed using the KEY command. DKEY is used to unkey the radio. (If the radio is left in a keyed state it is automatically unkeyed after several minutes.) The RSSI is sampled in a raw, continuous fashion regardless of whether the unit is a master or a remote. Entering Q or QUIT returns the system to normal operation. A timer keeps the Setup mode from accidentally leaving the system disabled. After 10 minutes the system behaves as if Q or QUIT had been entered, returning to normal operation. SER Displays the Serial Number of the radio. SHOW PWR The SHOW PWR command displays the actual (measured) RF power output in dBm. Unlike the PWR command, this command shows the actual level being measured, not the programmed RF power setting. SHOW SYNC When used at a Remote station, this command will display Extended Address and Unit Address of the Master or Extension radio to which the Remote is synchronized. The network depth at the remote, defined as the number of downstream links from the Master, is displayed in parentheses. SKIP [NONE, 1...8]

This command sets or displays which, if any, of the eight 3.2 MHz-wide zones will be skipped from the radios hopping sequence. Skipping zones is one way of dealing with constant interference on one or more frequencies. See DEALING WITH INTERFERENCE on Page 32 for more information on dealing with interference. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 49 The command parameter is either the keyword NONE or an undelimited string of up to four digits where each digit 1...8 represents a corresponding zone to skip. (For zone parameter input, the digits can appear in any order and can be optionally separated by a blank space.) The SKIP command is display-only at remote radios. (Remotes must be synchronized with the master radio to display the skip status.) In the USA, a maximum of four zones may be skipped, per FCC rules. Check the regulatory requirements for your region before deleting zones. SLEEP [ON, OFF]

This command is used to set or display the radios Sleep Mode setting. The default setting is SLEEP OFF. When this mode is enabled (ON), a ground or logic low on Pin 6 of the 16-pin header connector (J3) suspends all normal radio functions, and power consumption is reduced to approximately 8 mA. The radio remains in this state until the low is removed. This function cannot be turned on for a Master or Extension radio. SREV This command displays the version of the firmware currently loaded into the transceiver. A display of 06-4040A01, 2.0.0 is an example of the firmware version identifierpart number followed by release/version number. STAT This command is used to check the alarm status of the radio. If no alarms exist, the message NO ALARMS PRESENT is returned. If an alarm does exist, a two-digit alarm code (0031) is displayed and the event is identified as a Major or Minor alarm. A brief description of the event is also given. If more than one alarm exists, the word MORE appears, and additional alarms may be viewed by pressing the alarm codes are provided in Table 17 on Page 54. key. Detailed descriptions of the ENTER TEMP This command displays the internal temperature of the transceiver in degrees Celsius. (Note that the radio is specified to operate in an environment between 30 C and +60 C). This internal reading may be higher than the outside temperature by several degrees. TX [xxxx]

This command sets or displays the test transmit frequency used in place of hopping whenever the radio is in Setup mode. The test transmit frequency can be reprogrammed to any value between 2.4016 GHz and 2.4782 GHz, inclusive. The factory default setting is 2.42420 GHz. 50 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 UNIT [1000065000]

This command sets the unit addressing for network-wide diagnostics. The unit address is factory programmed to the last four digits of the serial number. If re-programmed in the field, the entry must consist of five digits between 10000 and 65000. XADDR [031]

Display or program the Extended Address of this radio that will serve as a common address for the sub-network synchronized to this Master or Extension. This value can be listed in the XPRI parameter of associated Extension or Remote radios to allow them to synchronize to this radio. We recommend setting the Master to zero (0). It is easy to remember, and is the default address when the INIT command is used. (Programmed only in Master and Extension radios.) XMAP [00000000-FFFFFFFF]

XMAP is a 32-bit hex entry where the least significant bit represents XADDR 0 and the most significant bit represents XADDR 31. The full 32-bit hex value represents the entire list of extensions with which the radio will be allowed to communicate. (Remotes and Extensions only.) This parameter is easily programmed through the TransNET Configuration Softwares Store and Forward Settings panel. XPRI [031]

Display or program the extended address of a primary radio with which this radio will attempt to synchronize and communicate. A setting of NONE will allow the unit to synchronize with any Master or Extension in the XMAP list.

(Parameter only meaningful for a Remote or Extension.) XRSSI [NONE, 40...120]

The XRSSI command is used to set the RSSI minimum signal level required to preserve synchronization with a non-primary Extension radio. This parameter will be ignored if XPRI is set to NONE. ZONE CLEAR The ZONE CLEAR command clears the zone data for all zones in the Zone Data Log, resetting the count to 0. (Zone data is also cleared automatically upon reboot.) ZONE DATA The transceiver divides its frequency operating spectrum into eight 3.2 MHz-wide zones. (These are the same zones referenced by the SKIP command described earlier.) Data frame statistics are maintained for each zone to indicate the transmission quality of data through the network. This information is useful for identifying zones where significant interference exists. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 51 Zone quality information can be accessed using the ZONE DATA command. For each zone (18), it shows you the number of data frames sent, the number received, and the number received with errors. If an excessive number of errors are seen in one or more frequency zones, it may indicate interference, and you should consider skipping those zones using the SKIP command. Note: If a frequency zone has been skipped, all counts for that zone will be zeros. The ZONE DATA format is displayed as follows:

1:TX TOTAL 00000000 1:RX TOTAL 00000000 1:RX ERROR 00000000 x:

x:

x:

8:TX TOTAL 00000000 8:RX TOTAL 00000000 8:RX ERROR 00000000 All data is based on payload packets. Incoming network data may be divided up into multiple packets for over-the-air transfers. The number before the colon represents the zone. TX TOTAL is the transmit packet total. RX TOTAL is the receive packet total. RX ERROR is the total number of received packets with CRC errors. All zone data is reset with the ZONE CLEAR command. 11.0 TROUBLESHOOTING Successful troubleshooting of the radio system is not difficult, but requires a logical approach. It is best to begin troubleshooting at the master station, as the rest of the system depends on the master for polling instructions and synchronization data. If the master station has problems, the operation of the entire network will be affected. When communication problems are found, it is good practice to begin by checking the simple things. All radios in the network must meet these basic requirements:

Adequate and stable primary power An efficient and properly aligned antenna system Secure connections (RF, data & power) Proper programming of the radios operating parameters, especially Mode selection (MODE), Network Address (ADDR), and interface Baud Rate (BAUD) The correct interface between the radio and the connected data equipment (proper cable wiring, data format and timing). In store-and-forward systems there are several areas that must be carefully evaluated:

52 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Duplicate XADDR values on MODE M and MODE X radios will cause failures unless the radios are far enough apart to not hear each other. Errors in the synchronization qualiers, XPRI and XMAP, on corresponding Remote radios. SAF must be enabled at the Master 11.1 Alarm Codes When an alarm condition exists, the transceiver creates an alarm code. These codes can be very helpful in resolving many system difficulties. Checking for AlarmsSTAT command To check for the presence of alarms, enter STAT. If no alarms exist, the message NO ALARMS PRESENT appears at the top of the display. If an alarm does exist, a two-digit alarm code (0031) is displayed, and it is identified as a major or minor alarm. A brief description of the alarm is also given. Alarm codes and their meanings are listed in Table 17. If more than one alarm exists, the word MORE appears at the bottom of the screen; additional alarms can be viewed by pressing ENTER

. Major Alarms vs. Minor Alarms Major alarms report serious conditions that generally indicate a hardware failure, or other abnormal condition that will prevent (or seriously hamper) further operation of the transceiver. With the exception of alarm code 00 (network address not programmed), major alarms generally indicate the need for factory repair. Contact your factory representative for further assistance. Minor alarms report conditions which, under most circumstances, will not prevent transceiver operation. This includes out-of-tolerance conditions, baud rate mismatches, etc. The cause of these alarms should be investigated and corrected to prevent system failure. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 53 Alarm Code Definitions Table 17 contains a listing of all event codes that may be reported by the transceiver.Additional alarm codes may be used in future firmware releases or are used by the factory. Table 17. Alarm Codes Alarm Code Alarm Type Description 00 01 04 08 10 12 16 17 18 29 30 31 Major Major Major Major Major Major Minor Minor Minor Minor Minor Minor The network address is not programmed. Improper firmware detected for this radio model. One or more of the programmable synthesizer loops is reporting an out-of-lock condition. The system is reporting that it has not been calibrated. Factory calibration is required for proper radio operation. The DSP was unable to properly program the system to the ap-

propriate defaults. A hardware problem may exist. Receiver time-out alarm. The unit address is not programmed. A data parity fault has been detected on the DATA connector. This usually indicates a parity setting mismatch between the ra-

dio and the RTU. A data framing error has been detected on the DATA connector. This may indicate a baud rate mismatch between the radio and the RTU. RF output power fault detected. (Power differs by more than 2 dB from set level.) Often caused by high antenna system SWR. Check antenna, feedline and connectors. The system is reporting an RSSI reading below 105 dBm. The transceivers internal temperature is approaching an out-of-tolerance condition. If the temperature drifts outside of the recommended operating range, system operation may fail. 54 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 11.2 LED Indicators The LED indicators on the transceiver board (CR3, CR-4, CR-5 and CR-6) are an important troubleshooting tool and should be checked whenever a problem is suspected. Table 18 describes the function of each status LED. Table 18.

If problems persist, contact the factory for further assistance. Refer to the inside back cover of this guide for contact information. MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 55 Table 19. Troubleshooting chart Difficulty Recommended System Checks Unit is inoperative. a.Check for the proper supply voltage at the transceiver, J3 Pins 5 and11. b.If using the Evaluation Board, the surface mount fuse may have opened. Refer to Section 4.3 below for replacement instruc-

tions. Interference is suspected. a.Verify that the system has a unique network address. Nearby systems with the same address will cause interference. No synchroniza-

tion with master, or poor overall performance. b.Check for interference and lockout any affected zone(s) using the SKIP command (Page 49). c. If omnidirectional antennas are used on remote stations, con-

sider changing to directional antennas. This will often limit inter-

ference to and from other stations. a.Check for secure interface connections at the radio and the connected device. b.Check the antenna, feedline and connectors. Reflected power should be less than 10% of the forward power reading

(SWR 2:1 or lower). c. If the remote radio is in synchronization, but performance is poor, check the received signal strength using the RSSI com-

mand (Page 48). If RSSI is low, it may indicate antenna prob-

lems, or misalignment of directional antenna headings. d.Verify proper programming of system parameters: mode, net-

work address, data interface baud rate, transmitter power, CTS delay, etc. For store-and-forward applications, also verify the following: SAF is ON; extended address is properly pro-

grammed at each extension; remotes are using the proper val-

ues for XPRI and XMAP. e.Check for alarms using the STAT command (Page 50) BER is too high. Data throughput is spotty. a.The RETRY and REPEAT commands may be increased to deal with interference, or decreased to increase throughput and reduce latency. b.Try turning on FEC. FEC on gives some coding gain, but comes at the cost of reduced throughput. Latency is too high. a.Reduce the REPEAT count. b.Turn BUFF OFF. BUFF ON insures that no gaps occur in the data, but this comes at the cost of increased latency. c. Make sure HOPTIME is set to 7. 11.4 Network-Wide Remote Diagnostics Diagnostics data from a remote radio can be obtained by connecting a laptop or personal computer running InSite diagnostics software (V6.6 or later) at any radio in the network. 56 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 NOTE: The diagnostics feature may not be available in all radios. The ability to query and configure a radio via Network-wide Diagnostics is based on the feature op-

tions purchased in the radio being polled. If a PC is connected to any radio in the network, intrusive polling (polling which briefly interrupts payload data transmission) can be performed. To perform diagnostics without interrupting payload data transmission, connect the PC to a radio defined as the root radio. A radio is defined as a root radio using the DTYPE ROOT command locally, at the radio. A complete explanation of remote diagnostics can be found in the Network-Wide Diagnostics System Handbook (Part No. 05-3467A01). Table 20. Network-Wide Diagnostics Commands Command Description DLINK [xxxxx/ON/OFF]

Details, page 43 Set baud rate of diagnostics link DTYPE [NODE/ROOT]

Details, page 44 Set radios operational characteristics for net-

work-wide diagnostics 1. Program one radio in the network as the root radio by entering the DTYPE ROOT command at the radio. 2. At the root radio, use the DLINK ON and DLINK [baud rate] commands to congure the diagnostic link protocol on the RJ-11 port. 3. Program all other radios in the network as nodes by entering the DTYPE NODE command at each radio. 4. Use the DLINK ON and DLINK [baud rate] commands to congure the diagnostic link protocol on the RJ-11 port of each node radio. 5. Connect a PC on which InSite software is installed to the root radio, or to one of the nodes, at the radios diagnostics port. To connect a PC to the radios DIAG port, an RJ-11 to DB-9 adapter (Part No. 03-3246A01) is required. If desired, an adapter cable may be constructed from scratch, using the information shown in Figure 10 on Page 11. 6. Launch the InSite program at the PC. (Refer to the InSite users manual for details.) MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 57 12.0 FIRMWARE UPGRADES From time to time, the factory releases new firmware for its radio products. An upgraded file can be installed in existing radios to take advantage of engineering improvements or additional features. 12.1 Obtaining new firmware The latest firmware for each radio type may be obtained free of charge from our website: www.microwavedata.com/service/technical/support/downloads/. Firmware is also available on disks from the factory that are bundled with an installation utility (Radio Software Upgradeupgrade.exe) for transferring the firmware file on the disk to the radio. Saving a Web-site firmware file to your PC Firmware upgrades are distributed as a plain-text (ASCII) file with a .S28 extension. Browse to find the desired .S28 file for your radio on the factory website at www.microwavedata.com. After finding your selection, use the right mouse button to select a path on your computer on which to save the file.

(If this isnt done, your browser may display the firmware file contents as text on the screen instead of downloading it to your local hard drive.) After the .S28 file has been saved to your computer, you may use either TransNET Configuration Software or Radio Software Upgrade programs to install this firmware in your radios. 12.2 Installing firmware in your radio 1. Connect a PC to radios diagnostic interface. 2. Start the TransNET Conguration Software. Open diagnostics port to the radio. The program will automatically read the radios prole. 3. From the File menu select Radio Firmware Upgrade and follow the prompts to install the new rmware into the radio. Do not press the Cancel button once the installation has started or it will leave the radio without any code. When the installation is complete, another radio may be connected to your PC and programmed. NOTE: If a firmware installation fails, the radio is left unprogrammed and inoperative. This is indicated by the PWR LED flashing slowly (1 second on/1 second off). This condition is only likely to occur if there is a power failure to the computer or radio during the installation process. The installation should be attempted again. 13.0 Security Today, the operation and management of an enterprise is becoming increasing dependent on electronic information flow. An accompanying concern becomes the security of the communication infrastructure and the security of the data itself. We take this matter seriously, and provide several means for protecting the data carried over our wireless products. 58 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 Our radios address this issue primarily through the use of the following items:

1) A proprietary modem/data link layerData signals are processed using code and hardware specically designed by the manufacturer. 2) A unique Network AddressThis provides a unique identier for each radio in a network. A radio is not addressable unless this unique code is included in the data string. 3) An optional encryption value (code)Setting an encryption code requires the use of the CODE command. This command scrambles the radios hop pattern and encrypts payload data content. A radio requires the correct Network Address (ADDR) and CODE value in order to synchronize. When the CODE command is used, the same value must be programmed into all radios in the network. See CODE [NONE, 1255] on Page 42 for more details. The effective combination of CODE and ADDR discourage the use of an exhaustive search to gain access to a system. The items described above provide sufficient security for most systems. For highly-sensitive applications, system designers should consider employing application level encryption into their polling protocols to further protect their systems. Third party software tools are available for adding encryption, and these should be considered as part of any advanced encryption scheme. 14.0 Product Specifications GENERAL Frequency Hopping Range:

MDS products are designed for long life and trouble-free operation. However, this equipment, as with all electronic equipment, may have an occasional component failure. The following information will assist you in the event that servicing becomes necessary. CUSTOMER ASSISTANCE Assistance for MDS products is available from our Customer Support Team during business hours (8:00 A.M.5:30 P.M. Eastern Time). When calling, please give the complete model number of the radio, along with a description of the trouble/symptom(s) that you are experiencing. In many cases, problems can be resolved over the telephone, without the need for returning the unit to the factory. Please use one of the following means for product assistance:

Phone: 585 241-5510 FAX: 585 242-8369 E-Mail: techsupport@microwavedata.com Web: www.microwavedata.com FACTORY SERVICE Component level repair of radio equipment is not recommended in the field. Many components are installed using surface mount technology, which requires specialized training and equipment for proper servicing. For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper operating specifications. If return of the equipment is necessary, you will be issued a Service Request Order (SRO) number. The SRO number will help expedite the repair so that the equipment can be repaired and returned to you as quickly as possible. Please be sure to include the SRO number on the outside of the shipping box, and on any correspondence relating to the repair. No equipment will be accepted for repair without an SRO number. A statement should accompany the radio describing, in detail, the trouble symptom(s), and a description of any associated equipment normally connected to the radio. It is also important to include the name and telephone number of a person in your organization who can be contacted if additional information is required. The radio must be properly packed for return to the factory. The original ship-

ping container and packaging materials should be used whenever possible. All factory returns should be addressed to:
