In my never ending quest for my GRT to work with my Tru Trak vision 385 and use the GPSS function I am asking our GRT experts for any help.
I have confirmed the unit is wired correctly for ARINC 429 Data so it has to be a configuration setting issue.
The input for serial port 5 is GPS1 Aviation / MapCom
The output for serial port 5 is set to (Autopilot) NMEA0182.
I believe it should be set to (Autopilot) Aviation.
I think this would provide the GPSS data I am missing?
Normally Systems generate GPSS by manipulating the Heading signals from the heading source(HSI). That is why I made the comment the GRT should generate GPSS.
If the Tru-track is getting Aviation data it makes me wonder it is generating GPSS? Then you would toggle the Tru-Track between Heading mode and GPSS.
