8 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 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 board’s RF/Antenna connection is not brought onto the 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. Figure 7. OEM Evaluation Board (P/N 03-4051A01) Table 2.

10 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 3.2 Cable Connections for Benchtop Testing There are four basic requirements for operating the transceiver and evaluation board in a benchtop test environment. They are:• Adequate and stable primary power• A proper antenna system or RF load (50 Ohms)• The correct interface wiring between the transceiver and the connected DTE device (RTU, PLC, etc.)• A connected PC terminal to read/set transceiver parameters.Figure 9 shows a typical setup for bench testing an OEM Transceiver. Two such setups will be required if you intend to establish over-the-air communications with another OEM transceiver. Invisible place holder Figure 9. Typical Test Setup Antenna Connection (J200 on the transceiver module) The Antenna connector is located at the upper left corner of the transceiver module and is a female MMCX-type coaxial connector. Connect an antenna or other suitable RF load to this connector.

MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 11 Do not apply DC power to the transceiver without first attaching a proper RF load, or the transceiver may be damaged. 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 Figure 10. RJ-11 to DB-9 Diagnostic Cable—Wiring Details (A pre-constructed cable is also available, Part No. 03-3246A01) Diagnostic Communication Modes Two methods may be used to communicate with the radio’s diagnostic port:• Terminal Interface —The PC is used in its basic terminal emulation 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 TransNET Support Package 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.CAUTIONPOSSIBLEEQUIPMENTDAMAGERXDTXDGND235DB-9 FEMALE(TO COMPUTER)TXDRXDGND456RJ-11 PLUG(TO TRANSCEIVER)RJ-11 PIN LAYOUT16
12 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01 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 data—RXD) and Pin 3 (transmit data—TXD). Additionally, some systems may require the use of Pin 7 (Request-to-send—RTS). If hardware flow control is desired, Pin 7 (RTS) and Pin 8 (CTS) may also need connection.Table 3 gives pin details for radios configured for RS/EIA-232 service. Table 4 gives details for radios configured for RS/EIA-485 service. NOTE: Radios equipped with a payload TTL interface are presented as RS-232 mode from the Evaluation Board.Figure 11.

MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 15The transceiver must be used only with negative-ground systems. Make certain that the polarity of the power source is correct.Invisible place holderFigure 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 transceiver’s current draw during bench testing.3.3 Initial Power-Up & ConfigurationWhen 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.CAUTIONPOSSIBLEEQUIPMENTDAMAGELeadScrews (2)BindingWire Ports (2)(Polarity: Left +, Right –)RetainingScrews (2)

See Configuration Settings below for programming details.4. Observe the transceiver’s 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 SettingsThis 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:Mode—Master, Remote, or ExtensionNetwork Address—a unique number from 1–65000Data Interface Parameters—bps, data bits, parity, stop bitsBand—set 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 (1–65000) using ADDR command. Each radio in the system must have the same network address. Tip: Use the last four digits of the master station’s serial number to help avoid conflicts 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 (1200–115200 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.
MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 17RXDTXDDCDGPConfiguring Multiple Remote UnitsIn 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 equipment—such as the Master, Remote, and any Extensions—on 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 PC’s 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 IndicatorsThe LED indicators are located to the right of the transceiver’s 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:•GP lamp lit continuously•DCD lamp lit continuously (if unit is synchronized with another station)• Remote radio(s) transmitting data (TXD) and receiving data (RXD) with another station.Table 5.
