M9B-HFS INTERFACE M9B-HFS OPERATION
Release 1.0 (97/10) 3-1
3. M9B-HFS OPERATION
The M9B-HFS interface controller card enables you to send and receive data via the fiber optic communication
line which connects your supply to a computer. You can use the computer controller to issue commands to the
power supply for programming, queries, calibration, or status. The power supply responds to the complete set of
device dependent software commands shown in Section
3.3 Command Reference.
3.1 Command Syntax
3.1.1 Manual Conventions
The manual uses these conventions when displaying command information. These characters are not part of the
command but are used to denote parameters used with the command.
< > (angle brackets) Angle brackets enclose a parameter. Do not include the angle brackets in the
command line you send to the computer.
/ (slash) Separates two alternative parameters. When a slash separates two parameters, you
can use either parameter to achieve the same result.
Example: <1/ON>
Entering 1 or ON will achieve the same result.
COMPUTER ENTRY Words typed on the computer are shown in Arial text, full capitals.
3.1.2 Command Format and Parameters
The device-dependent language for the M9B-HFS 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 3.1-1 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
