Quick Start Guide 1919B                                            June 2004
                                                                     Transceiver
Welcome to the Quick Start Guide for RAD-ISM-900-DATA-BD Data Transceiver.
This 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 and
RAD-ISM-900-DATA-BD
The 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 fluctuate by more than 10% of its
rated power.

Connecting your Devices to the RAD-ISM-900-RS232-BD or
RAD-ISM-900-DATA-BD
RS-232 Port Connections
Some 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)
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.

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

Installing the software
Visit www.phoenixcon.com/wireless, download RADLINK.exe. Once download
is complete, double-click the RADLINK.exe file. Follow the instructions on the
screen.

Running the software
Select “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 9. Setting parameters




Getting Your PC to Communicate with the Transceiver
The 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”, “Configure 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
   Configure” 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 Parameters
1. 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 specific 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 Parameters
1. 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 file 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 flicker 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 Concerns
The 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).
Establishing the Radio Link
1. 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 flashed 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,
     since 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          Figure 10. RSSI Test Points
     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 Transceivers
With 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 flash, 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 flashing as data is passed, the
RX LED on slave you are communicating with should also flash. This indicates
that the slave is receiving data. If the slave transceiver’s TX LED flashes, you
should also see the master transceiver’s RX LED flash, which means data has
successfully passed in both directions.

If the slave transceiver’s TX LED does not flash, 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 flash and the RX LED on the master
transceiver also flashes, 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
configurations.

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.
If used in a Class I, Div. 2 area, do not
disconnect equipment unless power has
been switched off or the area is known
to be non-hazardous.
