That is the cable I bought yesterday and tried last night, but, I still cannot get it work. Maybe something is wrong in the 950? I will try and meter it when I get a chance.

Most likely there is something odd going on with the 5100. I remember struggling with it a bit when I first got it. Per your previous post, the 950 is plugged into an "always on" outlet on the 5100 and the 950's main trigger output is connected to the 5100's trigger input, so the wiring is all correct. Do you have the front pushbotton on the 5100 in the "on" position? If it is still in the "off" position, the trigger will not work and the switched outlets will be off all the time.

Gonk, yes, I have the 950 plugged into an "always on" outlet and the 950's main trigger going to the 5100. as soon as I plug into the 5100, it shuts off like it is getting no signal regardless of whether I have the 950 on or in standby, the power button on the 5100 is "on". since I have tried two different cables I'm guessing the fault is with either the output of the 950 or the input of the 5100.thanks for the reply.

Well, I tested the voltage coming out of the 950 and I am getting 11.71 volts so, I guess there is a problem with the input on the 5100. I will investigate that further and see if it is something I can fix.

OK, just an update here.For whatever reason,the two different cables I tried would not make a connection into the 5100, however as soon as I put a 3.5mm to 3.5mm female to male adapter into the equation it worked. don't know why.. it might be a millimeter longer, but,it finally works!
