Thanks for the great feedback Hngrdg, ?I am hoping it is not a port failure. ?Unfortunately my programmer has become very busy over the last few years to do these minor tweaks for him. I think he is a great guy and awesome programmer but just has outgrown small residential jobs unfortunately. I had a similar problem happen to me withy Bipad ?where one of the ports stopped working so I did have him a few years ago move it from port 4 to 10, and instantly it had started working. When my new emitters come in and I get the previous three ports wired up I am hoping everything should work if not I will then try your Apple phone trick
" Just to recap press a command on ML600 and look at Emitter with iPhone camera in selfie mode ?select FaceTime and see if it flashes? "
As for having Stripped wire going to the correct port, after 15 hours of trouble shooting I am pretty sure I had tried every combination possible, that being said I could've made a mistake you never know?
I was curious I can test each port for example E,F,G,H separated with a two plug Phoenix connector they don't have to be all plugged in at the same time with 8 pin Phoenix connector, I assume every signal port is independent of each other ??
Thanks Again
