760 Mhz Data Transceiver Users Manual 
LUM0000XX Rev A 
Version 1.0 
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 to operate in Point-to-Point applications.  To establish 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). 
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). 
5. 
Connect antennas to the transceiver. Any 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. 
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.
