RE: Multiplex help... really technical
Going back to my days at UNIVAC and doing TTL logic design The rules were that you could connect up to 10 circuits to a TTL output BUT they had to be in series with a terminating resistor at the end You were not allowed to have parrallel circuits since the signal went down one line bounced back and made all kinds of reflections and much trouble. It sounds like the output of the receiver in question could have a open collector output in which case you would not see a signal with a scope. Try putting a resistor from the output pin to the voltage(red wire) a 5k would work OK If you are going to connect more than one servo to a receiver output you will be creatting a parallel ciruit and you could have problems with signal levels and servo operation use the Y harness that have IC in them as this gives each servo it's own output I have never tried this but putting a resistor from the signal pin to the red wire would probably help also
