GRT Avionics

I am installing an ATEX 345 406 ELT. Mine can receive Aviation format GPS at 9600 Baud Rate with the RS-232 connection. (NMEA at 4800 Baud Rate can be configured before purchase). I connected it to the Horizon, but I currently have a TruTrak AutoPilot, so am using the the Autopilot (Aviation) 'role' for that and the Horizon will not allow the same role to be used in two different ports. I scrolled through all the other 'roles' as an option for output, but cannot find one that will deliver what I am hoping. Any options?

We don't have multiple Aviation outputs. You would have to splice the wire going to the TruTrak to send it to both.

Will do. Thanks!
