Look at computer-properties-hardware-device manager. Look for Ports. Your USB port should show up. Click on it and check if the "Device is Working Properly". Check the baud rate,parity, etc settings, as well as the Com port number. Match them with the RS-Linx settings.
You will need a compatible motor drive that works for 4 quadrant operation. That's because you will be forcing the motor to rotate the opposite direction from which it is powering rotation. I have built tensioners using drives from KB Electronics that can be run in torque mode. DC permanent...
