ORIGINAL: rctom What Alan is saying is if you don't use the SPC port for receiver power the jumper plug that came with the receiver must be plugged into the SPC port. Did you do that? TF
not sure what you mean or are comparing, that is one in the same.... either plug into the SPC port with a male to male or solder int he extra connector to your battery source, one in the same... I know that...
What I am asking is this: The daRn receivers should work even if I do NOT (not not not not) plug into the SPC port, as I did with ALL my 6 & 7 channel optima receivers until I got around to undoing my standing 7-channel systems and soldering into my battery source to make a connector for the SPC port, BUT please understand my QUESTION.... so far, all my 6 & 7 channel receivers ALL work via channel 3 throttle port or the battery 7th channel port, but why doesn't the 9-channel also work...
yes yes yes yes I understand the SPC you want for avoiding brown-outs, not asking this... thank you
Thank you all for your reply's.
Thanks again in advance for helping me determine this 9-channel scenario I am facing [

What I tried to convey, and again by rctom, andyou still have not clarified - is the SPCplug inserted when trying to power all fromthe servoside only?
The Optimatransceiverssignal connection to the servo port power bus is made through the jumper being inserted into the SPC port,
if the jumper is removed then the RX is isolated from the servo bus and the receiver will not work..
The SPC port can have a battery plugged into it which will power the RX so it can send signals. This battery connection does not provide any power to the servo bus. i.e. there must always be a SPC Plug or a battery (switch)plug connecting appropriate two pins in the SPCPort. The SPC and Battery Plugs Are Wired Differently..
