The generic reference of RM-232 will be used throughout this manual when referring

to any one of the RM-232-xxx modem variants mentioned above. Specific information

relating to a specific radio modem type will be noted by using the full radio modem

name.

The RM-232-xxx Radio Modem

The RM-232 Radio Modem provides the capability of a short range, reliable wireless

point-to-point and point-to-multipoint RF data communications link.

The RM-232 can be used in a variety of data communications applications that require

a simple to use invisible data link. The radio modem is designed to interface to a

variety of host devices. These devices include computers, PDA’s, personal organisers,

PLC’s, data loggers, SCADA devices and intelligent control & transducer systems.

The serial data transferred over the radio link is not altered; the output serial data

stream is the same as the input serial data stream. The radio modems provide a two-

way data communications links, where each unit can accept serial data and also

output serial data.

The RM-232 radio modems are fully self-contained units, requiring only an external

12VDC power source or a PP3 battery to operate. The radio modules used in the radio

modems have been selected to meet the requirements of unlicensed operation in the

international ISM bands, and are therefore acceptable for use in many countries.

Installation and Operation

This chapter describes basic connection procedures and operation. It also covers the

front panel indicator lights and physical mounting and positioning of the radio modem.

Serial Interface

The RM-232 radio modem interfaces to external DTE equipment using a 9 way D type

female connector. The serial interface is configured as DCE equipment with the pin

out shown in the table below.

Pin Name DCE Function

2 RXD Receive Data (out)

3 TXD Transmit Data (in)

4 DTR Data Terminal Ready (in)

5 SG Signal Ground

7 RTS Ready To Send (in)

8 CTS Clear To Send (out)

The serial protocol supported by the radio modem is fixed at 8 data bit, 1 stop bit and

no parity. Flow control can be user selected as either hardware (RTS/CTS), software

(XON/XOFF) and none. The serial baud rate is also user configurable and supports

the following rates: 600, 1200, 2400, 4800, 9600, 14400, 38400, 57600, and 115200.

When operating the radio modem at a DTE baud rate greater than the configured on-

air data throughput, data received by the radio modem will be buffered internally. At

the higher DTE baud rates either hardware or software flow control should be used to

prevent receive buffer overflows in the radio modem.

Connecting for the First Time

Follow the steps below to connect the RM-232 radio modem to your computer.

Connecting to your computer or terminal equipment

Connect the supplied 9 way data cable to the radio

modem and to a suitable serial data port on your

computer. If the serial data port on your computer is a

25 way connector, you will require a suitable 9 way to

25 way adapter. The D9 DTE (host) to D9 DCE (radio

modem) pin connection diagram is shown in the

diagram opposite.

Supplying power to the Radio Modems

The RM-232 radio modem requires either an internal 9V PP3 battery or a 9-

12VDC mains adapter to operate. An external power source is strongly advised

when running the radio modem continuously.

When using a PP3 battery to power the RM-232 we recommend either an

Alkaline or NiMH battery. Before installing a battery ensure the radio modem

User’s Guide Installation 2-2

power switch is in the OFF position. Open the battery compartment on the back

of the radio modem, connect and insert the battery before replacing the battery

cover. The diagram below shows the recommended placement and orientation

of the PP3 battery.

Battery

Recommended battery placement.

The Radio Modem is fitted with a DC power socket for use with an external

regulated 9-12VDC power source. The diagram below shows the power socket

polarity. Plugging an external power source into the DC jack effectively

disconnects the internal battery (if one is installed).

Power socket type and polarity.

Contact your distributor if you require an appropriate regulated mains power

supply to suit.

User’s Guide Installation 2-3

Starting your computer

Switch your computer on if it is not already running, and start your favorite

communications application (such as Hyperteminal for Windows). The radio

modems are factory set to a default serial baud rate of 9600 bps, 8 data bits, 1

stop bit, no parity and no flow control. Ensure your communication application

or remote terminal device is configured to these settings. Your radio modems

are now ready for use. Default operating mode for the RM-232 is in point-to-

point mode.

If you require different interface settings to the factory set defaults, you will

need to refer to the later chapter covering the radio modem configuration

commands.

Switching on the Radio Modems

Slide the power switch on the side of the Radio Modem to the ON position (as

shown in the diagram below).

Slide the power switch to the ON position.

Once power is applied to the radio modem you should see a welcome message

appear on the communications application display (as shown below). The

displayed mode of operation will change to reflect the currently configured

mode of the radio modem.

Signon message as displayed upon power-up

As the signon message is provided purely as a diagnostic aid during initial

connection and setup of the radio modem, it should be disabled from within the

configurator before final commisioning.

The status LED indicator on the front of the radio modem should be showing 1

short pulse every 2 seconds (approximately). This indicates the radio modem is

in standby mode. The receive LED indicator (green) will also be flashing

regularly indicating it is listening for radio transmissions.

User’s Guide Installation 2-4

Sending Serial Data

Assuming both radio modems are connected and operating correctly, you are

now ready to send some data. Ensure the two radio modems are spaced with

at least 5 or more metres between them.

Entering keystrokes in the communications application on one computer should

result in those characters appearing in the communications application on the

remote computer.

Front Panel Indicator Lights

The radio modem has 3 indicator LEDs on the front panel. These LEDs are used to

give the radio modem operator an indication of the current state of operation of the

Radio Modem.

Indicator State Meaning

Transmit Red Radio transmitting.

Receive Green steady Link established and listening for data.

Receive Green flash Radio in standby mode waiting to establish a link.

Receive Red Radio receiving data.

Status Single pulsing Radio Modem is active but no link is established.

Status Double pulsing

Status On/Off (0.5 sec)

ttempting to connect to a remote Radio Modem.

Status On/Off (2 secs) Low battery indication. (Two second flash rate)

Status On Radio Modem is in setup and configuration mode.

Mounting the Radio Modem

Each radio modem is supplied with two lengths of adhesive backed Velcro. This

Velcro can be used to mount the radio modem on a wall, window, carpet covered

divider, or onto anything the hooked Velcro itself, or the Velcro adhesive will adhere to.

When applying the Velcro to the rear of the radio modem, ensure it does not obstruct

the battery compartment, as access will be required in order to change batteries.

Figure 1 shows the recommended placement of the Velcro to the rear of each radio

modem.
