Wiring Notes

All units are supplied with a 4-conductor cable.

For the transmitter/transponder, the simplest configuration is just supplying power to the transmitter. In operating scenarios, serial communication is only used for commanding sync and the serial data lines can be left unconnected. However, if you are planning to use the GPS re-tweets you will need to connect the serial lines.

Warning: If using an external power source for either the transmitter or receiver, it is essential to connect the power source ground to the serial signals ground. See figure below.
