I have been trying to find out if anyone has ever been able to make a working serial connection between a Blue Mountain EFIS and a TruTrak autopilot. I have made many phone calls and searched all the web sites.
According the BMA the G3 Lite will provide a gps output through one of its two serial ports in either GPSS (UPS GPS) or standard NMEA-0183 format.
According to TruTrak their autopilots will accept and read GPSS or NMEA-0183 format (with the correct baud setting programed into the autopilot).
Here's the strange part. None of the tech reps at either company can confirm that their units will work with the other. Nor do they know if anyone anywhere has ever made a working connection between the two systems. I find this very odd that the manufacturers don't know the basic compatibility of the equipment they sell.
Here is my question for the Forum. Do you know or have you heard of anyone who has ever made a working gps serial connection between any Blue Mountain EFIS and any TruTrak autopilot? If so, I would love to hear from you.
