Rover 4.6.3 SF40 Issue on Serial2 with CubeOrangePlus

Hello All,

I have an SF40 installed on an Ardurover 4.6.3. I can test the SF40 in the lightware studio and it works Great and with the same wiring i have it connected on the Telemetry port 2 of a Cube Orange Plus. I tested also switching Tx/Rx but i can make it work on Telem2. Spoke with Lightware support and they told me they tested 4.6.3 and Telem2 and for them also did not work. But they tested on GPS2 and for them it worked. Any ideas on what might be the cause specifically on Serial2 with this firmware?
