G5, GSU 25, GDU 460 Wiring (Electrical)
4.0 Hours

Today, I added the CAN bus, and RS-232 connection to the G5 connector. I added in the CAN bus terminator and fired everything up (GMU-11, GSA 28, and GEA 24) to see if the CAN bus would work. Initially, the G5 was throwing a ton of CAN bus errors, so I turned it off and checked the wires. Turned out I had accidentally swapped the HI and LO sides of the CAN bus at the G5 connector. I switched them back and suddenly the CAN bus was working fine.

Then, I wired the CAN bus, power, and RS-232 out from the GSU 25 ADAHRS.

Then I spent an hour or so looking for the config module for the GDU 460 connector. I know I received it in my avionics shipment, but I can't find it anywhere. I guess I'll have to blow $100 on another one.

I started working on the GDU 460 CAN bus, power, and RS-232 from the GEA-24. I didn't quite have time to fire it up and see if it runs, yet.
