3M™ MicroTouch™ Controller EX Serial Reference Guide
Mounting the Sensor
Turning On Your System
Status Light (LED) Diagnostics
There are several methods for mounting the sensor depending on your application. If you
need instructions or recommendations from 3M Touch Systems on how to incorporate a
sensor into your design, refer to the 3M™ MicroTouch™ System 3250EX Integration
Guide (P/N 19-278). All 3M Touch Systems documentation is available from the
corporate website at www.3Mtouch.com.
Before you turn on your touch system, ensure that all cables are connected properly and
that the controller is properly mounted. Be sure to tighten all cable connector screws.
To start up your system:
1. Turn on your display and computer.
2. Adjust the contrast and brightness to suit your personal preference and working
3. Adjust the horizontal and vertical position controls on the display to center the image
3M™ MicroTouch™ controllers are highly reliable units; however, there may be
occasions when the controller does not perform exactly as you expected. The EX serial
controller provides diagnostic feedback with a light emitting diode (LED) on the
component side of the board that indicates the status of the touch system.
If the LED is on, and remains dimly lit, the controller has power and is operating
properly. If the LED is off, the controller is not receiving power.
When you power-up the unit, the LED is bright until the controller start-up sequence is
completed. Following start-up, the LED becomes dim and remains dim as long as you do
not touch the sensor. When you touch the sensor, the LED becomes bright as long as a
touch is detected.
A flashing (or blinking) LED during power-up indicates the controller’s power-on
self-test failed. Refer to Table 4 for a description of each error code.
