16.3 Wall Control
e wall control consists of a front panel with LED display and keys for user input. e electronic cir-
cuit with a micro-controller is located behind the front panel. It is responsible for processing the user
input for camera and light controls and for output certain operating conditions on the LEDs. Commu-
nication with the primary electronic control system takes place via the CAN bus. e electronic con-
trol system of the terminal has a 9-pole sub-D plug. All control signals (CAN, serial) and the voltage
supply utilize this plug. e circuits are connected separately to comply with EMC regulations.
e terminal has two equivalent electronic control systems, because every light system consists of two
independent lights.
e functions of the terminal are briey described in the following diagram.
