What to do if Raven TM-1 Control Unit shows no GPS/GGA?
- MMichael BartlettAug 3, 2025
If your Raven Control Unit is not displaying GPS/GGA information, verify that the GPS receiver is outputting GGA messages and that the serial connector is properly installed on the GPS input. Also, check that the GPS receiver baud rate is set between 9600 and 57600 baud.
