External Brightness Adjustment - Omron NS - REV 12 Setup Manual

3-10 External Brightness Adjustment

3-10 External Brightness Adjustment

Connect a variable resistor to the external brightness adjustment connector on the NS-series PT to externally
adjust the brightness of the backlight in the touch panel. This allows the brightness to be set lower than the
Low selection in the backlight brightness settings ( High, Medium, and Low ) under the operating settings for
NS-series PTs. Brightness can be adjusted externally only with the NS15.
