Table 4-3: Configuration Control Modes.
Note that the active configuration mode is saved when saving a setup to a non-volatile register. If
the firmware of the KDC power supply is updated in the field, it may be necessary to reset NVM
settings with the correct configuration setting. This can be done by changing the power on default
to RST, cycling the power, setting the unit up as desired, saving the new setup in REG0 and then
assigning REG0 as the power on setting. See 4.2.7 for details on using setup registers.
Note: Switching modes between MASTER, AUX AS and AUX AT can be done by
changing the configuration setting only. Switching to AUX AP mode
however requires changes to the controller jumper settings. See section
5.2.1 for hardware configuration details.
