Note 2 Only for the Vision 312Plus products.
Note 3 The lifetime of a LED, when operated at an ambient temperature of 25 ±2
○
C, is
defined as the time until the brightness reaches less than 50% of its original value.
Note that the LED lifetime will be shorter than specified in this document if the LED
operates in a higher ambient temperature.
For power supply below 7.5 V, see section 6.1.2.1.
9.2 Ambient light sensor
The ambient light sensor detects the ambient light intensity and adjusts the LCD brightness via application
software.

9.3 Status LED
The Status LED is an RGB LED. The color is programmable by the customer and its brightness is ad-
justable.
9.4 Touchscreen
The Vision 312 device is equipped with a projective capacitive touchscreen designed to be used as an
input device for the application running on the device. It can be operated with bare fingers and gloves.
The touchscreen supports multi-touch gestures with two fingers.
Water drops do not trigger touch functions. The touchscreen also supports palm suppression (the palm
on the touchscreen does not lead to erratic behavior).
