How to get Ch9 & 10 with SBUS from X4RSB receiver

[Allan Bennett]

I started out writing this to ask for help: I'm using my X4RSB receiver to send SBUS to a flybarless flight controller, but I also want to bypass the flight controller for 2 more channels by using CH9 & 10 PWM which should be on Ch 2 and 3 of the X4RSB.

The Rx was talking to my flight controller okay, using six channels through the SBUS connection, but I couldn't get Ch9 to respond through a PWM connection to Ch2. This afternoon it dawned on me that binding it to my Taranis in Ch9-16 mode with a jumpber across output pins 2 & 3, instead of binding in Ch1-8 mode with a jumper across output pins 2 & 3, might do the trick. And it did, so I'm posting here in case anyone else has this problem, since the instruction leaflet doesn't mention it.
