The connections were checked and tested with the (+) and (-) both ways on the Rx on the back box. Both ways they are hooked up result in the same thing... when I try to control the camera through the KBD, the screen flickers a little like it's receiving some type of signal, but isn't responding to it. The camera's address and the protocol (Pelco P) are verified to match the PSM file on the System Manager. The port# on the camera's entry on the PSM file also matches the port# on the CDU to which the control wires are connected.

It's the only camera on an Altronix 15a, 6 input box.

It's run to a 24v controller.... no more than 15 feet from the camera using 16ga wire.

I have a Pelco Spec IV camera that I cannot control. The camera has picture on the monitors, and the control wire is uninterrupted from the camera all the way to the Code Distribution Unit. When I try to control the camera using a Pelco CM9760-KBD, the screen flickers, but will not allow me to control the camera. The camera is brand new out of the box, as is the back box/PCB. The control wire is a shielded pair that runs into a twisted pair/punchdown block where it travels to the CDU. The distance isn't an issue, as I have other PTZs coming from the same location Any suggestions would be greatly appreciated. Thanks in advance.
