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.
Figure 45 Sync In connector
Figure 46 Sync Out connector
For internal sync, pins 2 and 6 are the only required connections. Connect these pins
using a straight cable. A straight cable can be used for all pin connections.
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.
