The voltage monitor (part of the Caterpillar board) allows the CaterpillarR to read a supply or battery voltage and report it through the ASCOM Safety Monitor interface. This can be used to trigger automatic close procedures if the supply voltage drops below a safe threshold.

Need: connector pinout, acceptable input voltage range, how to configure the threshold in software, and whether a resistor divider is needed for higher voltages. REVISAR.
