Sync Connections
There are two sync connectors: Sync In and Sync Out. The Sync In connector is normally connected to
a (custom) GPS antenna system, or to the Sync Out connector of a collocated radio.

For internal sync, connect pins 2 and 6 and cross over pins 3 and 5.
For GPS connections, the interconnection cable between radios must cross over pins 3 and 5, with all
other pins wired straight through.
All configurations do not require connections on pins 4, 7, and 8.
