PH4 Mini - set UART port as Telemetry 2 port

Hi guys, i want to use my Holybro Micro OSD and mini Pix4 for FPV with my PH4 mini using Fatshark fpv google but i have an error on the display: “Waiting for Mavlink heartbeat”.

OSD is link to UART port because primary telemetru to GS is on Tel1 port.

How can i set UART port to became a Tel 2 port? Is it possible?

Waiting repaly!:slight_smile:

If you mean the UART port (next to Tel1), I think it should be TELEM4
