Trying to use Serial5 on cube orange ac405


I’m trying to use serial5 connector for rangefinder LW20 without succes
can you help me?

I tryed the same setup on serial2 and it work perfectly.

So Maybe we can’t use it for range finder?

Try swapping RX/TX if you haven’t already. You can use an LW20 on any serial port.

If you have the carrier board with ADSB receiver then it is hardwired to Serial5
