Can the 10PX set the channel directly to one of these s.bus Decoders?

It does not seem to work for me. When I read via the direct connection, the LEDs on the decoder blink real fast but the 10PX always says it did not discover anything. I also tried it on CH1 of a R304SB but got similar results. It would seem this decoder should look just like an s.bus servo to the transmitter.

My next step was to buy a Futaba SBC-1 but it seems like this should work.

Thanks for any tips. This is the first time I have worked with s.bus.
