RS-422 Serial Commands
Note: In the following commands, “nn” represents the net node of the power
supply that is to receive the command. To send a global command to all power
supplies in a network configuration, “nn” should be set to C8 hex (200 decimal).
The “-- --” in the hex string is the MSB followed by the LSB of a type int. The
integer is the value found in the additional information column.
