Operating Manual for RS-232 for XPD Series Power Supply

Command

Format and
Parameters

The device-dependent language for the RS-232 Interface consists of commands and
parameters. A command is a one word code which either gives instructions to the
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 or

COMMAND ,

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
