Mark, The GPS 18x LVC is not hooked up to the RTCM correctly. The Garmin pin labeling is backwards to what you think. I learned this by trial and error on my setup. See below. Swap 6 and 14. RTCM GPS 18x LVC 6 GRX <-- Rx Data 6 Green 7 GPPS <-- Pulse Output 1 Yellow 8 GND Ground 3 Black 8 GND Ground 5 Black 13 +5V --> Vin 2 Red 14 GTX --> TX Data 4 White Then log into the rtcm and do 98 and you should see this Current Time: Sun Apr 20, 2014 04:37:02.820 Last Rx Pkt System time: 04/20/2014 03:55:35.580, diff: 2487260 msec Last Rx Pkt Timestamp time: 04/20/2014 03:55:32.064, diff: 3515 msec Last Rx Pkt index: 160, inbounds: 1 You change your debug mode to 40 and see the gps setences Mike On Sat, Apr 19, 2014 at 10:55 PM, Mark Johnston <markjohnston73@gmail.com>wrote:

--- No the LED's do not come on for GPS/HST rechecked the wiring all looks right assuming GTX is transmit that goes to the GPS rx line and vice versa
GPPS pin 7 is labeled as PTT out in the documentation - not sure what that means, I thought it was Gps 1pps?
