3. Precautions
Operation may become unstable, depending on the surrounding environment.
Do not use the controller under environments that affect capacitance values (The affecting factors are such
as power-supply noises).
The application tool, TPOffset must be executed before operating DMC’s touch screens of capacitive
multi-touch type (EXC series and DUS series) with the DUS series controller.
TPOffset is the application software executable on Windows. It can be downloaded from the DMC’s website
below.
