Table 3.5	Programming Commands
Command	Description

AUXA	Selects the state of the AUXA output signal on the J21-7 connector.

AUXB	Selects the state of the AUXB output signal on the J21-8 connector.

CLR	Initializes the power supply to its Power ON (PON) state.

DLY	Sets a programmable time delay which is executed by the supply
	before reporting fault conditions after a new output voltage or current is
	specified.
FOLD	Sets foldback mode for the supply.

HOLD	Enables or disables voltage/current setting hold mode for the supply.

IMAX	Sets an upper soft limit on the programmed output current for the
	supply.

ISET	Sets the output current of the supply in amps (default) or in milliamps.

OUT	Enables or disables voltage/current output for the supply.

OVSET	Sets the over voltage protection trip point for the supply in volts
	(default) or in millivolts.
RST	Resets the supply to the present voltage and current settings if the
	output is disabled by OVP or foldback protection.

SRQ	Enables or disables the power supply's ability to generate a service
	request.
TRG	Implements programmed voltage and current settings which had been
	in hold mode.
VMAX	Sets an upper soft limit on the supply’s programmed output voltage.

VSET	Sets the output voltage of the power supply in volts (default) or in
	millivolts.
