I have been trying for hours to get ahold of GRT to answer a simple question about the ARINC module for their Sport EFIS. I have left messages and have called probably 20 times and can't get a soul to answer the phone. Maybe someone on here can help.
The installation page for the ARINC module has two wires to hook up to the Sport serial port 4 in and out, and two wire to hook up to serial port 4 in and out. I know it sounds like the same thing, but that's what it says. Does anybody know what the second two wires are supposed to do?
Any help would be appreciated.
