Ras Pi to modem via USB...900mhz to nodelink 0-10v out

I want to take digital output from my rasberry pi, route it via USB to a 900mhz transmitter, then receive it at a nodelink (I think) and get a 0-10V analog output that will mimic an ebike throttle control (1-5V hall sensor output) to operate a brushless motor controller.

or is there a direct add on for ras pi so I don’t even need the USB link??

What do I need?
PR55-21A_mega or PR55-17A and one of those end node units ( can’t find a part number)
