EC2 Cable

This cable connects the back of a touch monitor to an external controller. It is a straight through cable, and all nine pins are used. Check this cable with an ohmmeter.

The internal construction of the EC2 cable is specific to the IntelliTouch system, and other common computer data cables should not be substituted.
