*Factory Default Settings
• The Node and Inputs Aux Power pins supply power to the node electronics. These pins
must be powered at all times for communication node and Inputs to be functional.
• The internal electronic fuses exist to protect against damage due to catastrophic failure
of internal components. External fuses are always recommended for protection against
power supply failure and over-current conditions.
