Radiolink Mini Pix Troubleshooting

Hi -
Radio AT10 ii
RX R12DS

Plugging an ESC in the RX the radio can control the ESC.

I believe all is wired correct with the Mini Pix however the radio calibration in mission planner does not see any controls from my radio. Please help

Thank you
Keith

It was not in SBUS mode - once I did that it worked.
