Figure 9: Repeater
The repeater timing is such that both the master and slave radios transmit and receive
simultaneously. Therefore the repeater radios will not interfere with each other. It is
important that both the master and slave radios have the same SFD code. The repeater
cards are powered by 5V and a DC converter is used in 12V operations.

Operation
3.1 Configuring and Accessing the Trailblazer Unit
3.1.1 Connecting the Serial Cable
You can access your Trailblazer with the GUI program, included on the Carlson Wireless
product CD, and the included serial cable. Simply plug the DB 9 connector of the serial
cable into the serial port on your computer and the three pin connector to the three pin
connector (COM1) on the radio board (bottom board) as shown.
NOTE: Unpredictable results may occur if you are using a USB to serial
COM Port adapter!
If you find that you need to replace the serial cable contact Carlson Wireless directly, or
see
Section 6.3.1
in the Appendix, for a pin-out and description on how to make one the
serial cable.
