Great, I begin to see the light at the end of the tunnel - thanks, FaT Air. So, since I'm using a DMX741, I will not connect the servo wires, right (I don't have one)? The motor wires, if my understanding is correct, are interchangeable - one extends the arm, the other, retracts - is this correct? This means I have to connect in such a way that pushing the left button on the positioner equals arm extension, i.e., eastward movement, correct? About the sensor wiring, which one goes on top and which one goes to the bottom? Will it depend on how the wiring in the actuator is done? And why are these needed? - Could I just move the dish to one side or to the other manually? I apologize for my ignorance on the subject, I'm new to C-band, as ku band stopped being a challenge. Thanks.
