Noob with a new transmitter setup help

So I bought myself a Turnigy 9XR Pro and got a Frsky DJT ACCST module and a D4R-II 4CH Receiver.
I’m able to bind to just fine, but I don’t think the parts are talking to one another.
Probably cuz I have no idea what I need to do in the settings of my transmitter.
For instance, I know what TAER stands for, but what order should it be in and what difference does that make?

Are you trying to get this working on cleanflight? If so the TAER stands for Throttle, Aileron, Elevator, Rudder. And that just specofies the receiver channel order that cleanflight reads. So if you move the throttle stick on your radio and the aileron channel moves in cleanflight you will either need to change the settings on your radio, or change the channel mapping in cleanflight to be ATER, as you can just type the mapping into that field within the cleanflight gui
