Touch screen
The DLoG ITC 7 is optionally available with a resistive touch screen.
The resistive touch screens from DLoG have a sandwich construction. The front control
panel is made of polyester and is separated from the back through very small spacer
dots. The rear of the front and the face of the back are covered which a conductive layer.
Voltage is applied at the corners of the back. By creating the contact between the surface
of the front and the conductive layer the electric circuit is closed, and the contact point
can be calculated from the voltage differences.
The touch screen can be operated with or without a keyboard and is compatible with a
mouse.
11.1.
Operation
When used improperly, for example with sharp objects such as screwdrivers, the
resistive touch screen will be irreparably damaged. Please observe chapter
.
11.2.
Mouse compatibility
It depends on the touch controller configuration if it is possible to connect a PS/2 mouse.
If the touch controller is configured as PS/2 touch (via jumpers) a
mouse cannot be connected to the external PS/2 mouse port. Of
course it is always possible to use a serial or a USB mouse at the
same time as the touch screen.
