I'm in the early stage of (paper) wiring up my G3X system and would like to open this up as a thread - I invite advice and critiques, and I'll share the information as I get answers from the G3Xperts.
My planned system:
GDU 460 - 1
G5 - 2
GTR 20 - 1
GEA 24 engine interface
GAD 29 acars / data concentrator
GMA 240 audio panel
GMC 307 autopilot panel
GSA 28 - 2 servos
GSU 25 adhars
GMU
GNC 255A
GTN 625
My preliminary interconnect drawing (based on the Garmin basic drawing):
I just sent an email to [email protected] with a question about the connections between the GDU and the GTN nav. I asked about the diagram on page 24-25 of the G3X manual that shows two RS232 connections to two separate GDUs. One is the MXMAP format channel, and the other is a Connext channel. I asked if I need both channels to my single GDU. If it requires two channels, I am out of serial channels to the GDU which has 5 max.
I have also asked about routing the GNC 255 to the GAD 29 instead of using a serial channel to the GDU. I'll post the answers I get as I get them.
I find this stuff fascinating, but it do make your head buzz once in a while and I can see why a lot of folks go to Stein and others to have it done.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
