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
