Wiring Digiflight II for GPS and Nav

Hi everyone,

This has got me stumped.
I have an AFS 3500 with ARINC 429, Garmin 695, Garmin SL30 and a Digiflight II.
I am trying to figure out how to wire up the system so that I can fly a flight plan programmed in the 695, or fly a heading/maintain a radial from the SL30, selected on the 3500.

My current plan is the following:
Wire the SL30 serial into serial port 3 on the AFS.
Wire the blue serial output on the 695 to Serial port 1 on the AFS.
Wire the ARINC 429 pins 9, 10 and 22, to the serial port 4 on the AFS

Add GPS blue serial input to pin 17 gps serial input on the Digiflight II.
Wire ARINC out A/B (obs/ap) pins 13 and 25, to pins 14 and 15 on the Digiflight II.

Will wiring the system this way work?

This is all super confusing to me, as I still do not understand well enough how the individual devices use the signals between them.

Any help would be greatly appreciated.
 
I have none of this equipment. But I know you never wire ARINC to RS232 - they don?t speak the same language. And RS232 is always ?out? to ?in?. Never in to in.
 
Hi Bob,
The ARINC to serial port is the ARiNC serial to AFS 3500 serial connection in the install manual for the 3500. I should have been more clear.
Thanks for the feedback.
