Radio Calibration Green Bars but NO MOVEMENT [RESOLVED]

Hello All,

I am currently working on a project involving Ardupilot and have a problem getting the green bars on the radio calibration screen to move with the sticks on the transmitter. Here are the systems I am working with:
Microcontroller: Matek H743 Slim
Receiver: Spektrum 4651T
Transmitter: NX10

The receiver is wired as such:
Ground to Ground
Power to 5V
Signal to Tx6

And Configuration is:
SERIAL6_BAUD = 115
SERIAL6_PROTOCOL = 23
SERIAL6_OPTIONS = 4

Any ideas on how I could resolve this and get the green bars moving with the transmitter?

Resolved: Tx6 is Serial 7 in ardupilot NOT Serial 6.

Isn’t it covered here?
Matek H743

Figured it out thank you for the helpful site link. I was using serial 6 for the tx6 pin when I should’ve been using serial 7.
