MGL Avionics User Forum

Hi,

I want them to send the GPS signal from the LX to MGL FF4 in order to calculate range. I don’t have a MGL RDAC. I have a LXNAV RS485 splitting unit, but I think I don’t need to use it.

If anyone has done something similar can you guide me, step by step, how to do it?

I think I need to use 1 cable connected to the PDA port in the LX and use cable on pin 5 (Output - data out RS232 - transmit line) . This cable I should connect to the purple cable (12) in FF4 (CAN Lo). And what about ground? Do I also need to connect? In this case it would be cable 1 (or 2] on the LX side to cable black (2) on the FF4.

For the LX please check page 52 of installation manual: https://gliding.lxnav.com/wp-content/up ... _rev39.pdf

Is this correct?

Thanks in advance,
Joaquim

Hello.
You want to connect the LX RS232 Output to the FF-4 RS232 Input, e.g DB15-Pin 4.
The harness delivered with the FF-4 may not contains a wire to DB15 pin 4
Make sure both devices use same Baud Rate
