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,

 

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,
