their is a Serial conector on the end of the ptz camera, but it has a conector on it that splilts the plug into a coaxal line then 4 other lines Red, Black, Green, White. I think the Red and Black are 12v power and the others are the Data lines. This is the same for all 4 PTZ's, in need to fine a wiring diagram to wire it the the serial conector or to a card, but i need to connect all 4 ptz. I am just not sure if i can daisy chain the Ptzs, if so how?
to the serial port.
