John — you’ll have to check whatever documentation you can find on the B&G, and 
see if it: #1 — even has an NMEA0183 output; and #2 — can output the “RSA” 
(rudder sensor angle) sentence.

Usually, NMEA0183 implementation on older autopilots is limited to input of 
NMEA0183 sentences having to do with navigation to a waypoint.

If you find documentation and need some translation, let me know.
