Welcome to the Quick Start Guide for RAD-ISM-900-DATA-BD Data Transceiver. Quick Start Guide for RAD-ISM-900-DATA-BD Data Transceiver. Quick Start Guide for RAD-ISM-900-DATA-BD Data TransceiverThis guide provides step-by-step instructions with simple explanations to start up a functional system. For detailed information, please refer to the RAD-ISM-900-DATA Series Operation Guide.

The RAD-ISM-900-RS232-BD and RAD-ISM-900-DATA-BD are wireless transceiver modems intended for interfacing with PLCs/RTUs. A typical network will consist of one master transceiver that connects to a PC or PLC through its RS-232 or RS-485 port. There can be up to 254 slave sites and each slave site can also function as a repeater for more distant sites.

The Difference Between RAD-ISM-900-RS232-BD andRAD-ISM-900-DATA-BDThe RAD-ISM-900-RS232-BD is a radio modem with an RS-232 port for programming and for data transfer. It offers a remote diagnostics port with a mini-DIN connector, however, data can only be transferred using the RS-232 port.

The RAD-ISM-900-DATA-BD is a radio modem that has both an RS-232 port and an RS-485 port. Either port may be used to transfer data, however, the unit must be programmed through the RS-232 port.

Power Connections:The RAD-ISM-900-RS232-BD and RAD-ISM-900-DATA-BD can accept input power from 9 to 30 VDC, although 12 VDC or 24 VDC power supplies are recommended. The power supply should not fl uctuate by more than 10% of its rated power.

Connecting your Devices to the RAD-ISM-900-RS232-BD or RAD-ISM-900-DATA-BDRS-232 Port ConnectionsSome devices will require the use of a straight-through 9-pin serial cable to connect between the device and the transceiver, whereas other devices will require a null modem cable. The quickest method to get an operational system is to try both cables. Plug either cable into both devices and apply power to the transceiver. When the RX LED turns on, the transceiver has power applied. If the TX LED turns on, the transceiver has power applied and you have the correct cable. If the TX LED does not turn on, try the other cable. Do not proceed until the TX LED is on solid green.

RS-485 Port Connections (on the RAD-ISM-900-DATA-BD only)If the RS-485 port is being used to transfer data, use the following wire diagrams.

DIP Switch Settings (RAD-ISM-900-DATA-BD only)

Figure 7. Tabs pressed in, housing slide down

There are four DIP switches located inside the RAD-ISM-900-DATA-BD transceiver. They determine which port (RS-232 or RS-485) is to be used to send data through, and if RS-485, whether 2-wire or 4-wire operation is desired.

To access the switches, press in the insert tabs located just below the terminal block on each side of the transceiver and partially remove the housing.

Set the DIP switches to the desired position:

OFF ON

Switch 1 RS-232 port RS-422/485

Switch 2 2-wire half duplex 4-wire full duplex

Switches 3 and 4 have no connection.

Programming the RAD-ISM-900-RS232-BD orRAD-ISM-900-DATA-BDThe RADLink software must be used to program each transceiver operation.

Installing the softwareVisit www.phoenixcon.com/wireless, download RADLINK.exe. Once download is complete, double-click the RADLINK.exe fi le. Follow the instructions on the screen.

Running the softwareSelect “Start”, “Programs”, “Phoenix Contact”, “RADLink” to run the program.

There are a number of parameters that must be entered into the RADLink software and then downloaded to each transceiver. This Quick Start Guide assumes a basic network layout of one master transceiver communicating to any number of slaves, with no repeaters.

Figure 8. DIP switches being adjusted

Figure 9. Setting parameters

Getting Your PC to Communicate with the TransceiverThe port settings on your PC must match the port settings on the transceiver in order for it to communicate. These settings include baud rate, data, stop and parity bits. The transceivers factory default settings are 9600, 8 data bits, 1 stop bit and no parity. The port settings of the PLC/RTU that is connected to each slave transceiver must also match the transceiver’s port settings.

1. Select “Project”, “Confi gure Comm Port...”. If the settings such as baud rate, parity, etc. are grayed-out, that comm port is not available. Select an available comm port.

2. Set the comm port to match the settings on the transceiver - or select “Auto Confi gure” to have the computer try every combination to determine what the transceiver is set to. If you select “Default”, it will set your comm port to the transceiver’s factory default port settings (9600 baud, 8 data bits, 1 stop bit and no parity).

Note: If you change the baud rate settings on your transceiver and download them to the unit, you will no longer be able to communicate with it until you change your PC comm port settings to match.

Transceiver Group Parameters1. Enter a Group ID between 1 and 63. This distinguishes your network from

another network in the same area. All transceivers in a group that are to communicate with each other must have the same ID.

2. Enter a Security ID between 0 and 65,534. This prevents other users from communicating with your transceivers. All transceivers in a group that are to communicate with each other must have the same security ID.

3. Enter an RF Band between 1 and 4. This determines which band of frequencies your network will be using. All transceivers in a group that are to communicate with each other must use the same RF Band.

4. Turn off ReTX Broadcasts. This is specifi c to the master transceiver only when using Modbus or AB’s DF1 protocol.

5. Select “No” repeaters. This Quick Start Guide assumes a basic network with no repeaters.

Individual Transceiver Parameters1. Enter a transceiver ID. Each transceiver in a group (master and slaves)

must have a different ID.

2. Enter Transceiver Mode (master/slave). There can only be one master transceiver in a group - all other transceivers are slaves or repeaters. Program each transceiver accordingly.

3. Port Protocol. Select “None” for all transceivers. The network can be optimized if you are using MODBUS or DF1 by changing this setting, but for system commissioning, set it to “None”.

4. RAD-ISM-900 Transceiver Type Setting. Select DATA-BD to match the model number of your transceiver. This setting applies to both types of transceivers covered in this Quick Start Guide.

5. Handshaking. If the devices you are connecting to the transceiver require hardware handshaking on the CTS/RTS pins of the RS-232 port, select “Yes”. Large fi le transfers such as downloading a data logger will require handshaking, as will streaming data from a device such as a weigh scale. The majority of industrial applications do not require handshaking.

6. Buffer Mode. If your protocol is Modbus or a Modbus derivative, select packet mode. For other protocols, select character.

7. Baud Rate. Select the desired baud rate - note that each transceiver can have a different baud rate - this has to match the device it will be connected to.

8. Data Bits. Select the number of data bits that will be included in each character. Typical setting is 8 data bits, with 7 data bits used only in rare circumstances such as Modbus ASCII protocol.

9. Stop Bits. Select the number of stop bits that will be used at the end of each character. The vast majority of applications use 1 stop bit.

10. Parity. Select whether a parity bit is used in each character, and, if so, even or odd. (Note: The majority of devices use no parity.)

Select “Set Radio” and allow up to 10 seconds for the parameters to be downloaded. You should see your computer screen fl icker as each parameter is downloaded. The more parameters you change from your transceiver’s previous settings the longer it will take to download.

• Cycle the power on the transceiver.

• Select “Project”, “Get Local Radio Parameters”

• Verify that all the settings were downloaded to the transceiver, then proceed to program the next transceiver.

Mounting and Environmental ConcernsThe transceiver mounts onto a 35mm DIN-rail and can be removed by depressing the spring-loaded release clip using a slotted screwdriver. It is rated NEMA 1, and must be protected from the weather conditions. The temperature rating is -40° to +158°F (-40° to +70°C).

Figure 10. RSSI Test Points

Establishing the Radio Link1. Connect the antenna to each transceiver. It does not impact the

transceiver’s RF performance if the shield of the antenna is grounded or not. This is only done for lightning protection reasons. If the center conductor of the co-axial cable is grounded, range and propagation will be reduced.

2. Apply power to all transceivers and observe the RF LED. On the master transceiver the RF LED will be on solid green regardless of whether an RF link has been established with any of the slave transceivers. When each slave transceiver has established an RF link with the master, its RF LED will go solid green. When each slave has a solid green RF LED, proceed to the next step. If the RF LED on the slave transceiver fl ashed slowly (once every two seconds), the slave transceiver has power applied, but is not locked on to a master. Try increasing the antenna gain or the mounting height of the antenna to improved reception.

3. Antenna recommendations for master and slave. The master transceiver should us an omni-directional antenna if there are multiple slave transceivers and they are outside of the beam width of a yagi antenna. A high gain omni antenna should be considered for the master, since it will have to communicate with the most distant slave transceiver. The slave transceivers should use yagi antennas to focus their RF energy in the direction of the master.

4. Measure the Received Signal Strength Indicator (RSSI) . On the top or side of each transceiver, there is a multi-meter test point labeled RSSI. This test point provides a 0-5VDC output that is proportional to the received signal strength. On the master transceiver, this measurement is not indicative of reception, not indicative of reception, notsince you will not know which slave the master is polling. Measure this voltage on the slave transceivers only. Place the negative lead of your multi-meter on the power supply negative terminal and place the positive lead on the RSSI test point. A voltage reading of 2.0 to 2.5 VDC indicates marginal radio link, and a reading of higher than 2.5 VDC indicates a strong (desired) radio link. Try increasing the antenna gain or the mounting height of the antenna to improved reception.

Sending Data Through the TransceiversWith the transceivers powered up and radio links established,try sending a command from the master PLC/PC to gather data from a remote device. View the master transceiver’s TX LED. If the LED does not fl ash, adjust the port settings on the master transceiver to ensure they match the PLC/RTU it is connected to (baud rate and data format).

Once the master transceiver has its TX LED fl ashing as data is passed, the RX LED on slave you are communicating with should also fl ash. This indicates that the slave is receiving data. If the slave transceiver’s TX LED fl ashes, you should also see the master transceiver’s RX LED fl ash, which means data has successfully passed in both directions.

If the slave transceiver’s TX LED does not fl ash, check the following:

1. The port settings on the slave transceiver must match the port settings of the remote PLC/RTU (baud rate, data format).

2. The address of the command coming from the master PC/PLC must match that of the remote device, otherwise, the remote device will ignore the command.

If the slave transceiver’s TX LED does fl ash and the RX LED on the master transceiver also fl ashes, but communication errors on the PLC result, try increasing the timeout on the PLC to a higher setting.

1) This jumper is necessary for programming over wireless due to the fact that the controller will Auto-logout on a cable break. This Auto-logout is not a disconnect; it simply prevents writing to the controller or changing the state of the controller from Run to Stop, etc.

2) These jumpers are optional depending on the handshaking that is selected in the device

1) Placing a 120 ohm resistor between 1 & 2 on the Momentum side and 13 & 14 on the RAD-ISM-900 side is required to truly meet the RS422/485 standard. This is a 4-wire full duplex connection.

2) The Modicon Momentum does not support Auto-logout on ports using RS485 protocol; therefore. if

programming using this link, the user must be sure to log off the PLC connection. If this is not done, the PLC may lockout future attempts to program it until power has been cycled to the Momentum.
