I’m installing a GX3 system with 1 GDU 460, a GAD29, GEA24, GSU25, GTR200, GMC 507, and GNX 375 navigator. Plus a ARTEX 345 ELT, GD-40 CO2 detector, Vertical Power system.
As I am installing I am looking the RS232 allocation. The GDU has 5 RS232 connections, well technically 6 if you count the one that is the backup for the GSU25. 2 of them are taken by the 375 navigator. 1 is taken by the Vertical Power. So that leaves 2 left. Here are the things that could be hooked up.
GEA24 Backup
GTR200 Backup -This might be the first to eliminated since I can manually tune the radio if needed in the event of CanBus failure.
CO2 (RX only)
ELT (TX only)
So here are a couple of questions.
1. There is one spare RS232 spot on the 375. It has 4 I believe and I am only using 3. Can I use that for the ELT instead of the GDU?
2. Can I split a RS232 configuration. In other words for example on RS232 #5, TX on RS232 #5 to the ELT and then use the RX side of that RS232 #5 to receive from the CO2 detector.
3. And lastly concerning the CANBUS. This is a bit confusing but the way I read it, I can us the P4X01 connection Pin 1 and 2 on the GSU25 and wire it directly to the P4X01 Pin 1 and 2 on the GDU 460. Not splicing this line it, its just an additional pathway into the CANBUS. Then use the the P4X02 On the GDU, pins 45 and 46 to put the GDU in the CANBUS daisy chain and skip the GSU25. Pretty sure that’s correct but if someone can back me up.
Thanks,
