Mounting the Touch Screen

There are several methods for mounting the touch screen depending on your application (CRT displays or flat panel displays, each in a variety of sizes). If you need instructions or recommendations from 3M Touch Systems on how to incorporate a touch screen into your OEM design, refer to the Touch Screen Kits Installation Guide (P/N 19-215) or the Flat Panel Display Integration Reference Guide (P/N 19-250). All 3M Touch Systems documentation is available from the corporate website at www.3Mtouch.com or from the Touch Solutions CD (P/N 19-640).

Handling and ESD Protection

When mounting the sensor and controller, use normal precautions for handling electrostatic sensitive devices. The EX II 3000SP has internal protection to 27 kV for ESD discharges that may occur during normal operation of the touch screen.

Turning On Your System

Before you turn on your custom 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 monitor and computer.

2.Adjust the contrast and brightness to suit your personal preference and working environment.

3.Adjust the horizontal and vertical position controls on the monitor to center the image on the screen.

The EX II 3000SP controller has a light emitting diode (LED) on one edge of the board that indicates the status of the touch screen unit.

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.

Status Light (LED) Diagnostics

3M Touch Systems controllers are highly reliable units; however, there may be occasions when the controller does not perform exactly as you expected. The EX II 3000SP controller provides diagnostic feedback with an LED indicator on the controller.
