Jim,

Thanks for looking at the issue. That was the problem! I have updated the pinout for anyone else that might need it. Also, does the RTCM just need the 1 PPS or does it need both 1 PPS and the NEMA string? 

RTCM GPS 18x LVC
7 GPPS <-- Pulse Output 1 Yellow
13 +5V --> Vin 2 Red
8 GND Ground 3 Black
14 GTX --> TX Data 4 White
8 GND Ground 5 Black
6 GRX <-- Rx Data 6 Green

Dont quote me on this, but I SWEAR (from questionable memory) that the pin that
the data goes from the "puck" to the RTCM on is on the BOTTOM row, not the top
(next to the PPS), so I would (off hand) say that you have your TX and RX reversed.

Again, this is entirely from memory. I may VERY WELL be wrong.

The best thing to do is try it.

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,
