External Brightness Adjustment - Omron NS - SETUP Setup Manual

3-10 External Brightness Adjustment

Connect a variable resistor to the external brightness adjustment connector on the NS-series PT to exter-
nally 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.
