What's Next?
Since this is a HID (human interface device) compatible controller, the controller will
operate independent of a 3M Touch Systems driver. You must obtain a HID
calibration utility from the 3M Touch Systems website for initial calibration.
Additional 3M Touch Systems documentation is available from the corporate website
at www.3Mtouch.com or from the Touch Solutions CD (P/N 19-640).
