Command Syntax

Command The device-dependent language for the RS-232 Interface consists of commands and Format and parameters. A command is a one word code which either gives instructions to the Parameters interface or asks for information from the interface. A command may be followed by

one or more parameters, a short code that changes the state of the power supply or the state of the bit register. Table 3.1, “Command Parameters” lists the parameters that affect the command set.

Format:

COMMAND or

COMMAND <parameter> or

COMMAND <parameter>,<parameter>

•You can enter commands in upper or lower case lettering.

Example: MASK FOLD = mask fold

•Do not further abbreviate command names or parameters.

Example:	MASK FOLD ≠ MK FOLD
	MASK FOLD ≠ MASK FD

•Use a space between the command and the first parameter. Any number of consecutive spaces is treated as one space. Numeric data may contain leading spaces. Embedded spaces between digits or between a digit and a decimal point are not accepted.

Example:	MASK FOLD = MASK		FOLD
	VOUT 3.4	= VOUT	3.4
	VOUT 3.4	≠ VOUT 3.	4

•Use commas between parameters in those commands with more than one parameter, and between mnemonic parameters as in the MASK and UNMASK commands. Only one comma is allowed and it may be preceded or followed by any number of spaces.

Example: MASK CV, OV, FOLD
