T&T: Chartplotter connection to an autopilot

[Peter Bennett]

I would connect:
Northstar Output A (violet) to autopilot Input +
Northstar Output B (gery) to autopilot Input -
Ignore the Northstar grounds.

You may also connect:
Autpoilot Out + to Northstar Input A
Autopilot Out - to Northstar Input B
This will probably pass the autopilot's compass reading to the
Northstar, but if the Northstar has its own compass, this is probably
not needed.
