How to Display OSD on Walksnail Avatar Goggles X

ArduPlane Plane 4.5

Good morning, I connected the Walksnail Avatar HD Pro Kit to the TX1 and RX1 pads and configured the parameters as shown here: DisplayPort OSD — Copter documentation. I configured serial3_protocol=42, but I can’t see anything on the glasses.
Can you please help me?
Thanks

TX1 and RX1 would probably indicate serial1 not serial3, but from what I saw this is not true for all FC.

According to what’s written here: Mateksys H743-Wing/SLIM/MINI/WLITE — Copter documentation , it should be serial 2. I’ll try when I get home.
Thanks

If not already configured, I’d also make sure OSD_TYPE: 5.

Solved. The UART1 port (tx1-rx1) on the Mateksys H743 Wing V3 is mapped to serial2. So: serial2_protocol=42; serial2_baud=115; osd_type=5 and everything works.
Thanks
