Does anyone know how to wire up this camera to a standard Multiplexer? I have the pin out from the Samsung manual, and have provided 12VDC on pin 6 with pin 4 as 12VDC ground. I wired up pin 2 as the video output with pin 3 as the video signal ground. However, I get nothing out of the camera with this wiring setup. When I plug the camera back into the RJ-11 jack on the 'giant/over-sized' Samsung box (which not only is unsightly, but has a blown CRT), the camera functions fine (there is a BNC pass through on the Samsung box (or now it is looking like there is a little something more going on with the signal coming from the camera before it is output on the BNC jacks). I'd greatly appreciate anyone's help who has had experience doing this. I have several of these cameras I want to tie into a standard multiplexor for digital recording, and I don't want to have the giant boxes with the ugly CRTs anymore. Thanks! Mike

Is the signal from pins 2 and 3 of the camera 'a balanced signal' (identical signals, but out of phase with each other - and therefore looks like 'no signal')? If that is the case, then I would say that Samsung labeled the pinout incorrectly in their manual because pin 3 shouldn't say 'GND', it should say 'signal -' or something like that, right? If the camera does output a balanced signal on pins 2 and 3, I believe I need a 'balun' (center tap transformer) to 'pick off' one side of the signal to be able to display it? - I think I may be on to something...I just read a great web page...http://www.ramelectronics.net/av-baluns.ep If it is this simple - then I don't need an expensive converter - just a small 'center tap transfomer' - and I'll be off and running...any recommendations where to find those? Again, Thanks! Mike

I appreciate your reply. I already have the 'power supply' made, do you have a 'converter' you'd recommend? Thanks!
