Quick Start

When purchased as a pair the FreeWave® Wireless Data Transceivers are

shipped from the factory pre-configured to operate together in point-to-point

applications. The Transceivers are preset for high-speed data communications

and to communicate only with each other.

FreeWave will potentially operate in virtually any environment where RS232 data

communications occur. The transceivers function as a 9 pin null modem cable.

If FreeWave is to be used in an application where a null modem cable is used

(such as communication between two computers), then FreeWave can be

connected directly. If FreeWave is to be used to replace a straight-through

RS232 cable, then a null modem cable must be placed between the transceiver

and the DCE instrument to which it is connected.

To establish communications between a pair of FreeWave Wireless Data

Transceivers just received from the factory:

1. Set the baud rate on each transceiver to match the baud rate of the instrument to

which it is attached. Please note that when you are setting the transceiver's baud

rate you are setting its RS232 data rate, which must match the rate for the

instrument to which it is attached. This in turn means that the baud rate does not

have to be on the same setting for the two transceivers.

2. Verify that the RS232 connector on the cable supplied will fit the RS232 interface

on the instrument to which it is being connected. The cable supplied will fit a 9

pin male RS232 connector, any other format will need an adapter or different

cable.

3. Connect Antennas to the modems. Any FreeWave transceiver may be operated

without an antenna for benchtop testing without concern for damaging the

product.

4. Connect the Transceiver to the instrument with the RS232 cable and attach the

power adapter to the Transceiver. Shortly after both modems are plugged in they

should establish a communications link with each other and your connection is

complete!

Note: The terms Modem and Transceiver are used interchangeably in this

manual and in the text of the setup menu. While the words have different

meanings, the two terms should be treated as one and the same for the

purposes of use of the FreeWave product.
