Operation

Table 3-7Command Reference

Command	Description
REN <1/ON>, <0/ R mote Enable. When set to REN 0, the power supply is in local mode. If a
OFF>	command is sent from the computer, the power supply does not respond but
	remains in local mode. When set to REN 1, the power supply will enter remote
	mode if a mmand is sent from the computer. See also “Remote/Local Operation”
	on page 2–20.
REN?	Asks for he state of the remote enable. See REN command.
	R ponse: REN <state>
ROM?	Asks for he version number of the master and slave EPROMs located on the
	interface PCB.
	R ponse: ROM M:<version> S:<version>
RST	R ets the supply to present voltage and current settings if the output is disabled by
	over voltage or foldback protection. Output values may be changed via VSET,
	ISET, and OVSET while the unit is disabled, but those values will not take effect
	until RST is applied.
STS?	Asks for he supply’s present status register. Status conditions are stored in the
	status reg ster. Each bit represents a separate condition. When the condition is true,
	the correspo ding bit is 1 (true). Bits remain set in the status register as long as the
	condition is true. See “Accumulated Status, Status, and Fault Registers” on page 3–
	17.
	Response: STS <status mask> where status mask is the decimal equivalent of the
	total bit weights for the operating conditions as listed in the status register.
TRG	Implements programmed voltage and current settings which had been in hold
	mode. The supply operates with previous values until the TRG (trigger) command
	is sent.
UNMASK	Enables you to select the supply operating conditions that you are most interested
<mnemonics>	in monitoring for fault occurrence. Mnemonics describing the conditions are
	separated from each other by commas, and may be sent in any order.
	Specifying one or more mnemonics which describe the conditions (or the decimal
	equivalent of their total bit weight) enables the selected conditions to set bits in the
	supply’s fault and status registers during operation. A bit is set in the fault register
	when the corresponding bit in the status register changes from 0 to 1 and the
	corresponding bit in the mask register is 1. See “Accumulated Status, Status, and
	Fault Registers” on page 3–17.
