The model is wmn-5090. When I give it power and press the setup button (only button on it) it moves out and swings back and forth left and right. I understand it's programing itself to know when it hits the wall for both left and right swings. There is a connector socket with a ex-link label on it. I assume that would be for a cable coming from a Samsung TV and the mount could be controlled via the TV remote control. What signal it's getting from the TV (left,right,up,down,each of 3 programmed positions) I don't know. Thanks for your interest, Phil
