I recently purchased a Walthers cornerstone 90' turntable (933-3171) with the motorizing kit (933-1050).  I assembled the motor in the turntable and am wondering, how to get the direction of travel with two wires.  I was told that I needed a decoder to get the direction of the motor.  Any information that you could give me on whether I need a decoder would be greatly appreciated.  Also, how to wire the decoder if it required.

Thank you,

Chuck

On the I/O port is a cad5 plug . Will a R12 plug work on the i/o port for the loconet on the digatrax system???.
