Trying to wire up the EDU450 carrier board with the Airunit 1.1. The documentation says, " **Please connect receiver to PPM（as picture showed），other 2 “SBUS” s are Sbus out**

What does this mean? It came with a cable that plugs into the Airunit’s Sbus port and breaks out into two connectors that can connect to the header area in the image routed by the black/yellow wires.

Does connector go on the Sbus header and the other on PPM header?

Plug in the s.bus 1 cable to ppm in… nothing else
