I have a new 5600T EFIS, looking at pins 11,12, 23, and 24 of the EFIS main connector DB25....

I see what seems to be conflicting schematics; it's either RS232, RS422, or specifically for the remote AHRS.
Does it matter? Is or can this port be used as a standard rs-232 serial port?


I need this "port 0" to connected to one of these:
- trigg 22 transponder
- GPS
- VPX
- EIS-4000
- remote Audio panel (PAC15ex)

The others will go on ports 1 --> 4

(radio and ADAHRS will go on SV-network)

Thanks,
Jeff
