I've just found this on the Emcotec website and thought it may be of interest to SBUS users.

It is similar to the SBD decoders but has 4 outputs and also appears to have the ability to change the servo parameters (e.g. reverse/end points etc) which I understand the SBD can't do.

It could effectively be used as 2 matchboxes in one unit (if using an SBUS receiver) which will be very helpful for me to free up a couple of channels.
