Scott tks for reply , new to the site so cant pm you yet. I'm telco interconnect guy, key and pbx systems etc, RJ11 is standard phone connections but the unit I was looking at specififed an RJ11E.
it is the connection for the camera. it used a 6 conductor modular end(which fits in a RJ11 jack) (a Rj45 8 pin connection is not needed)
The back of the monitor and the camera both have modular jacks, no BNC used. When we first connected a camera we did have an image but then lost it. I hope some one can let me know what signal is on what pin,
eg. + - voltage to power the camera, video xmit pair, there is also a mic
on the camera, etc. I'm hoping that the ports were not fried.
