I am installing several american dynamic PTZs. I am able to get them on by plugging them into a jbox but I'm not sure how to get control of them. There is a cable that leads out of the jbox which I assume is what needs to be connected to something but I dont know what. I intend to use an ad2088 controller hooked up to megapower 3200 matrix switcher. Does anyone know where the cable from the jbox needs to go?
