Brief Description: Wiring AP to GRT EFIS - check other wiring
I received a response from Carlos at GRT that pin 32 on the Sport is an acceptable RX serial in port to take the serial data from the auto pilot servos. I attached a yellow wire, about 4 inches long, with a grt pin to that port. I used a butt splice to connect the grn/blk wire from the pitch servo to the yellow wire and hence to pin 32 on the Sport. I covered the splice with black shrink.
The GRT Auto Pilot servo wiring is complete at this point. I will have to add the wiring from the roll servo which will mount in the wing at a later time. Those connections will be made at the connector block under the pilots seat.
My efforts to verify that the green and green/black wires from the stick are indeed the two wires for the green switch on the stick, proved unsuccessful. I connected the stick bundle to the forward bundle with the cannon plug which is inline. I know the stick bundle connection is made because I tested it and observed that the hat switch will change the sl 30 flip flop and the audio panel will switch from com1 to com2.
That leaves two issues regarding the stick. One is the PTT and the other is the two wires mentioned above.
I noticed that the clock/G metr has not yet been wired. That will be four wires.
