Used for parallel control/PV/PC functions
They are used for control and monitoring functions. Please refer
to 4.1.2 and 4.1.3.
Indicate the status of the supply and load condition.
Used to adjust output voltage. The one on the top for fine-tune,
the other for coarse-tune.
Position 1~3 are for device addressing when using communication
interface.
Position 4 is an internal termination resistor that prevents signal
rebound for differential signals of CAN bus and Modbus.
