Pictor 201XT cable questions

I have picked up a 201XT autoguider along with a Pictor 416XT imager and there are two telephone style cables. One of the cables has reversed wires and the other doesn't. Which cable connects the 201XT to the 416XT control box and which cable connects the control box to the LX200 mount? Thanks.

David,

It has been many.......many years since I used a 201XT but I recall that the cable from the 201XT does not go to the 416XT box but instead goes directly to the LX200 control panel. I "vaguely" remember that it takes a crossover cable. If you use the wrong cable the DEC axis will run wild because you are powering a normally active-low pin with steady +5V. You should not harm the electronics as long as you don't swap cables when the 201XT or LX200 are powered up but """"CHECK THE MANUALS""" first to avoid damage.

Do you have the manuals? They have the pinout diagrams. I still have the manuals and can help if necessary.
