All,
Can someone double-check interconnects for me?
The G3X installation manual , Rev AD, page 25-80, "LRU Pinouts for the GTX 23" states:
"RS-232 input channel 1 is used to receive pressure altitude and control commands, and to provide status,
TIS-A traffic, and other data. RS-232 output channel 1 provides unit status and TIS data. RS-232 channel
1 input and output are also used for software upgrades. RS-232 port channel 1 on the GTX should be
connected to the channel 1 RS-232 port on ADAHRS 1.
"
But, page 25-57 "LRU Pinouts for the GSU 25" states:
The GTX 23 installation manual, revision G page 4-5 doesn't specify which port to use on the controlling device (G3X in my case) -- which makes sense.
So should the GTX connect to Channel 3 or Channel 1 of the GSU 25? I thought that Channel 1 was the backup RS232 path for the GDU for a CAN failure.
Thanks,
Chris

2 Channels of RS-232 RX, and 3 Channels of RS-232 TX data.
RS-232 1: Can optionally be connected to a GDU display to provide a redundant path for attitude data.
Also used to configure a GSU 25 as ADAHRS #3.
RS-232 2: Transmits data to the GMU 22.
RS-232 3: Connects to a GTX transponder to provide pressure altitude data and remote transponder
control. Transponder should only be connected to ADAHRS 1 (not 2 or 3).
