I have a SC-30 compass and IF-NMEA2K2 converter that I am trying to use to supply a NMEA 0183 HEHDT string to a stabilized VSAT antenna that only accepts NMEA 0183. I am getting 0183 output from the NMEA converter to my PC over RS-232. I would like to program the device to only give an HEHDT output, as the antennas tend to experience intermittent issues when strings other than HEHDT are present. Is it possible to do this?
