[DG] [DG11] Es127 interfaced with st5000 autopilot

[Hannibal]

Hi, we have just installed a es98 and es127 mfd replacing two pathfinder series displays. The issue we have is the mfd locked autopilot heading is reading the same 266 deg locked heading regardless of boat heading. If we active the autopilot auto heading, mfd displays the right heading for about 2 seconds then reverts back to 266. Heading reading on autopilot and data box on mfd read correct, just the pop up autopilot box locked heading is incorrect.
The st5000 is on seatalk1 with converter to seatalk sting. It also has a older gps antenna on nmea0183. It doesn’t change if I specify internal gps on the data master mfd. The system also has a HD radar installed. Haven’t tried swinging compass yet, but noted deviation was at 0. Cheers.
