Hi Mark, Mine seems to be working, and the wiring is as above. Here is my RTCM GPS configuration 8 - GPS Data Protocol (0=NMEA, 1=TSIP) (0) 9 - GPS Serial Polarity (0=Non-Inverted, 1=Inverted) (0) 10 - GPS PPS Polarity (0=Non-Inverted, 1=Inverted, 2=NONE) (1) 11 - GPS Baud Rate (4800) Does it match? This is what I get on boot: GPS signal acquired, number of satellites in view = 11 03/29/2016 23:37:20.300 Warning: GPS Data time period elapsed 03/29/2016 23:37:20.300 Warning: GPS PPS Signal time period elapsed 03/29/2016 23:38:06.980 Time now syncronized to GPS 73, Skyler On Tue, Mar 29, 2016 at 2:41 PM, Mark DuMoulin @ WB2ERS <wb2ers@metcom.com> wrote:
Skyler,
Good afternoon.
I saw your post regarding the RTCM-GPS-18x LVC question.
I would use the app_rpt site but cannot seem to get registered.
I have tried many times to get registered on the app_rpt users but it always comes back no such user!!!
Here’s the question:
I have two of the same RTCM and Garmin GPS 18x LVC.
I have been completely unable to get either to work.
I followed your wiring:
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
No joy. Did you get yours working?
Anything you can share?
I have a feeling that the Garmin’s have been reprogrammed to something other than factory default 4800 in the PGRMF.
Tnx,
Mark DuMoulin Sr.
