So does your receiver only put out SBus and you previously used an SBus to PWM converter?
Or your receiver can put out PPM and you want to switch to PPM?
This is a Spektrum receiver. They sometimes use DSM.
the instructions say to plug the receiver into channel 9 I'm using the spektrum spm4649t, and it says to plug the ppm cable into channel 10 on the adapter.
Sorry. This confuses me. "plug the receiver into channel 9?" Receivers are usually the things that you say have a servo channel, so this comes out like plugging a receiver into itself. Maybe you are saying to plug the receiver into connector #9 on the adapter?
"plug the ppm cable into channel 10 on the adapter?" So are you saying that you want to use the adapter to convert SBus from the receiver into PPM? Why not just connect the SBus from the receiver straight into MainPort on the CC3D?
So you need SBus and not PPM going into CC3D?
SBus must use MainPort. PPM can use either MainPort or FlexiPort.
So reading between the lines, you have an SBus signal coming from the receiver. It used to go into an SBus to PWM adapter (which also can put out PPM) and the many PWM signals are plugged into the CC3D PWM input.
Of course you could still use that. I would probably use receiver SBus straight to CC3D MainPort.
