From the project

DMX Demonstrator

The Voltage IO module can generate a 0 to adjustable positive voltage which tracks the level of a channel. It is configurable to generate multiple output voltages to adapt it to any voltage range required. The default values listed in the schematic generate 0 to +10V since this is a common lighting control signal.
