Pixhawk 4 mini to Spektrum SRXL2

Gents MikeOxlong here,

I have a Pixhawk 4 mini that Im trying to pair with a Spektrum SRXL2 receiver I got from GETFPV.com

I have it in the “RC IN” port. Wired the following:
Ground, V+, and signal per the pixhawk manual.

now the N/C (whatever that does) is not plugged in because I only have 3 pins going to the Pixhawk.
It powers up and binds to my Jumper t-16 as X11 ms

The issue at hand is that on QGC its not showing any input. Plus when you click spektrum bind nothing happens.

Any ideas?
