Pin assignment on rear of the touch panel
The touch panel address
The touch panel address for interconnection is set on the 4-pole dip switch on the
rear of the touch panel.
If several touch panels (parallel switching of up to 3 touch panels) are used in the
controller, the setting must only be carried out on touch panel 1. All other touch
panels can keep their standard setting (all 8 DIP switches OFF).
