NMEA input needed for CH250 TLL output

Question

What is required for my CH250 to output Target Latitude and Longitude TLL to my plotter?

Solution

The CH250 needs both an NMEA GPS position input and an NMEA heading input to be able to output the TLL sentence.

Position Sentences: GGA, GLL, RMC
Heading Sentences: HDG, HDM

Note: The CH250 has only one NMEA input port so the GPS and Heading sentences will need to be combined.
