Pre | Xantrex Technology XMP 2600 manual

Alphabetical reference		Commands and Queries Reference
*PRE	assign new value to the Parallel Poll Enable Register. Re-calculates
	<ist>.
	Syntax	*PRE <int>
	Parameters	the value to be assigned to the Register - a decimal
		number in the range 0 to 255 representing bits in the
		Register.
	Category	Status	Type: Sequential
*PRE?	return the	value of the Parallel Poll Enable Register. The value
	returned is a decimal number in the range 0 to 255 representing the
	bits of the Register.
	Syntax	*PRE?
	Parameters	none
	Category	Status	Type: Sequential
*PSC	controls whether or not the XMP 2600 will clear all the Event Enable
	Registers and the SRQ and Parallel Poll Enable Registers at Power
	On.
	Syntax	*PSC <int>
	Parameters	a value of 0 disables the XMP 2600 from clearing
		the Registers at Power On. Any other value (in the
		range 1 to 255) enables clearing of the Register.
	Category	Status	Type: Sequential
*PSC?	return the	value of the Power On Status Clear Enable Flag: “0”
	(disabled) or “1” (enabled).
	Syntax	*PSC?
	Parameters	none
	Category	Status	Type: Sequential
*RCL	restores settings of all the Power Modules (same as RCL command).
	Syntax	*RCL <int>
	Parameters	a decimal number in the range 0 to 9 specifying the
		storage number the XMP 2600 will restore the
		settings from.
	Category	System	Type: Overlapped
*RST	returns the XMP 2600 to its		Power On state: send a Fault Reset
	Command to all faulty Power Modules, if the Primary was shut down
	then try to revive it, Initialize or Retain Power Modules Settings,
	return the Front Panel Display to Normal Status Mode. Does not clear
	the status structures (except for the Primary status).
	Syntax	*RST
	Parameters	none
	Category	System	Type: Sequential
