GP-20U7 Four terminals

Post by chlopez » Fri Aug 04, 2017 5:43 am

I'm about to use the GP-20U7 GPS module to connect to a Kenwood TH-D7A HT (built-in TNC)... the GP-20U7 module has four terminals (only three have cables connected, V, TX, GND).

The fourth terminal is for RX: Does that have any function in my proposed use? (The HT does have connections for GND, TX, RC)
