I?m having a heck of a time getting my Trutrak VSGV to work.
I am not absolutely certain that I have made the proper ARINC settings on the GTN. I feel that I have the correct RS232 setting.
What confuses me is the ARINC ?A? & ARINC ?B?. On the GTN ARINC configuration screen, there is no reference to ?A? or ?B?. I see ?ARINC 429 in 1? & ?ARINC 429 in 2? along with ?ARINC 429 out 1? & ?ARINC 429 out 2?.
Does the 1 & 2 refer to A & B or port number?
When I look at the pin-out list in the GTN install manual, I see reference to ARINC ?A? & ?B?.
I have tried a couple of different settings but get the same result: a right nose-down bank carnival ride.
I do get the A/P ?GPS OK? * a flashing asterisk; also get the TRK with the correct heading and a ?+? when a flight plan is entered. I have NEVER seen ?GPSS? show up on the A/P.
The three wires going from the GTN to A/P have continuity & go to the correct pinouts as far as I know.
The A/P has been back to Trutrack & Zack the tech guy says it?s ?ok?.
Also re-checked wiring to servos. All OK.
Any insight to my problem would be most appreciated.

PS
I recently emailed the avionics supplier & kindly asked to be ?walked-through? the configuration screens. I was told to refer to the (convoluted) configuration sheet that was provided and that was ?all that there is to do?. Some service after dropping $12k+ on this place.
I only regret that I didn?t buy my avionics stack from Walt or Stein, or someone that has presence on the forum. If you?re an avionics novice such as I, don?t be suckered into low prices.
