Video Alignment - 3M PX5 Series Reference Manual

3M™ Multi-Touch ASIC Controller Reference Guide

Video Alignment

The 3M Multi-Touch PCT PX Series System does not require video alignment if you are
able to accurately touch icons on the sensor. If after integrating the system you cannot do
this, the touch sensor's active area may not be correctly aligned to the underlying video.
To compensate for any variability in touch sensor placement during integration, you
should perform a video alignment of the sensor to the display to ensure touch accuracy.
There are three ways to perform a video alignment. Regardless of the operating system,
after you connect your touch display:
1. If you are using Windows®, you may calibrate by accessing the Software Diagnostic
Utility (SDU) found on our website.
Launch the SDU. Select the Tools menu and highlight Calibration. The screen below
appears and you should touch the 2 targets as they appear. Press Escape to cancel
Calibration.
