Trimble GFX 750

[Massey 6470]

I’m led to believe that the round pin on the back of the 750 will do external switch coverage mapping, GPS speed output and rs 232 port/ nmea output. Can anyone verify this and point me in the direction of the cable required

I think you need the expansion port to that

On the ezpilot pro loom (10) which I have I see nmea out but I can’t find any more info on it or a rs 232 to Deutch connector adapter
