How do you set up and log NMEA data from an LD5 unit?
The configuration method differs slightly, depending on the LD5 variant. On A Variants navigate to GNSS > Config. On B & C Variants navigate to GNSS > Config > NMEA.

Once the comport is selected press the Tick button to expose the list of available data steams, select GNSS NMEAa or GNSS NMEAb depending which option you selected in the earlier step and select Next:
