X10 SBUS input gives steady flickering

[flyingw]

SBUS requires a frame rate that is different that what the Taranis outputs in XJT-D16 mode.  SBUS specification is either 7ms (fast) or 14ms (normal).  Anything outside of these is not guaranteed to work properly.

Jim,

Ok, let's see if I understand this:

 - The Taranis outputs XJT-D16 through its external module bay to the XPS-J1 transmitter module at the frame rate of the Taranis XJT-D16 protocol.

 - Then the XPS-J1 module uses that same XJT-D16 frame rate to talk to the RFU.

 - Then the RFU outputs SBUS to the X10 at that same XJT-D16 frame rate.

 - Then the X10's green led blinks because the XJT-D16 frame rate is not consistent with the standard SBUS frame.

I reckon that the SBUS frame rate seen at the X10 is determined by the frame rate that the XPS-J1 module gets from the Taranis, is that correct?

I tried the test with the Taranis outputting PPM to the XPS-J1 module and the behavior was the same - blinking X10 led indicating frames lost.

Then it follows that the Taranis would have to send XJT-D16 or PPM SBUS frames to the XPS-J1 module at 14ms (or 7ms) in order for the X10 to be happy with the incoming SBUS frame rate.

Then why are there no lost frames (X10 led solid green) when the Taranis outputs either XJT-D16 or PPM to the XPS-J1 module, and the RFU talks Extreme protocol to the X10?  Is it because Extreme can adapt to either frame rate?

Thanks,
