Quick Start on a Point-to-Point Network
When purchased as a pair, the FreeWave®
Wireless Data Transceivers are shipped from the factory pre-
configured with most of the settings to operate in Point-to-Point applications. To establish
communications between a pair of FreeWave Wireless Data Transceivers just received from the factory:
communications between a pair of FreeWave Wireless Data Transceivers just received from the factory:
1.
Connect the transceiver to the instrument with the RS232 cable and also attach power. The
cable supplied with enclosed transceivers (except Waterproof) is a 9-pin male serial; professional
board level transceivers will need a separate programming cable (sold separately).

2.
Set the Modem mode in each transceiver. One should be set as a Point-to-Point Master (Mode
0) and the other set as a Point-to-Point Slave (Mode 1).
0) and the other set as a Point-to-Point Slave (Mode 1).
3.
Set the baud rate on each transceiver to match the baud rate of the instrument to which it is
attached. Please note, when setting the transceiver's baud rate, its RS232 data rate is set. The
baud rate does not have to be on the same setting for the two transceivers.

4.
Edit the Call Book. Enter the Slave serial number in the Master’s Call Book. Enter the Master’s
Serial number in the Slave’s Call Book, or disable Slave Security (in the Slave).
Serial number in the Slave’s Call Book, or disable Slave Security (in the Slave).
5.
Connect an antenna to each of the transceivers. Any unlicensed band FreeWave transceiver may
be operated without an antenna for bench-top testing without concern for damaging the product.
Noise potential may be reduced on the bench by lowering the Xmit power.

Noise potential may be reduced on the bench by lowering the Xmit power.
6.
Shortly after both transceivers are plugged in, they should establish a communications link with
each other and the connection is complete. Using the table below, verify that the radios are
operating as expected.
