Integrating the SC400 Controller
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 design, refer to the MicroTouch Resistive Integration Guide (P/N 19-441). All 3M
Touch Systems documentation is available from the corporate website at
www.3Mtouch.com
It is critical for you to understand the tail orientation of your touch screen prior to
connecting the controller. This will affect how the controller interprets your touch on the
screen. Refer to the Chapter on controller communications for additional details.
Touch Screen Cable Connector
The touch screen cable has a 4-pin single row locking female connector that plugs into
the controller. The controller is compatible with the "XYXY" latched connector pinout,
not the ""XXYY" style, non-latched connector pinout. Here, X or Y refers to one or the
other sheet, and + or – refers one or the other side of a sheet. The calibration process sorts
out left/right and up/down.
Connector pins 1 & 3 must be connected to one sheet and pins 2 & 4 must be connected
to the other sheet.

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.
