All,

I am setting up a voter system using the RTCM and GPS 18x LVC. Has anyone used the Garmin GPS 18x LVC to interface with the RTCM?

Here is the pinout I have. want to make sure it is correct. 

RTCM GPS 18x LVC
7 PTT Out <-- Pulse Output 1 Yellow
13 5Vdc --> Vin 2 Red
8 Ground Ground 3 Black
6 Rx Data <-- TX Data 4 White
8 Ground Ground 5 Black
14 TX Data --> Rx Data 6 Red

Thanks,

Mike - KD5DFB
