controller). A complete integration kit is also available: P/N 69-901.
• A 3M™ MicroTouch™ surface capacitive touch sensor
• A method of establishing the serial data communication between the controller and
your system. The 3M™ MicroTouch™ RS-232 serial cable (P/N 7311273) is
recommended.

• A touch driver with a calibration routine. You can use 3M™ MicroTouch™ MT 7
