Menu path: Setup > User Interface > Input > Touchscreen
To ensure that you can open the setup and navigate within it, the initial configuration should take place with a mouse and keyboard connected. The setup procedure with an on-screen keyboard is described below.
Touchscreen already calibrated If you enable the touchscreen function, the touchscreen must be calibrated first. Unless you enable this option, calibration will begin automatically after each system boot.
Swap X and Y values Enable this option if the mouse pointer moves vertically when you move your finger in a horizontal direction.
Minimum/maximum X value/Y value These values are determined by the calibration tool. However, you can also change them manually.
Let-go limit The maximum permitted time (in milliseconds) between two instances of contact in order to still be registered a single touch. When moving windows by drag-and-drop, for example, your contact with the screen may inadvertently be interrupted. Increasing this value prevents the thin client from registering two individual contacts in this case.
Contact limit Determines how long (in milliseconds) the screen needs to be touched in order for the contact to be recognized.
Baud rate (for serial touchscreens only) Determines the speed of communication via the selected connection. (If in doubt, read the monitor manual.)
Touchscreen connection You can connect the touchscreen either to COM1 or COM2. Select your preferred connection here.
Set driver-specific default settings Click on this button once after changing the touchscreen type or to restore the default settings.
