Serial Commands - Alphabetic Listing
Each command description provides the structure (long and short format), a description of the
command purpose, a command example, an example of what the command returns (as applicable to
query commands), and notes specific to the command. The list below applies to each group of
commands:
L Numeric data, specified by the mnemonic, <num>, uses ASCII characters to represent numbers.
Numbers may contain a plus or minus (+ or -) sign, decimal point (.), and exponent (E or e) with its
sign. If a fractional component is received when only an integer is required, the number is rounded to
the nearest integer without any resulting error message. The mnemonics DEF, MIN, and MAX are
often acceptable for the default, minimum, and maximum value respectively. Unit suffixes, such as V or
OHM, can be appended to numeric parameters and are accepted without error but ignored.
• Unrecognized commands or commands with incorrect syntax or invalid parameters generate error
messages in the error queue.
• Upper case letters designate syntax that is required when issuing the command.
• Lower case letters are optional and may be omitted.
• < > indicates a required parameter.
• [ ] indicates optional parameters.
• ( ) indicates a group of parameters that must be used together.
• For query commands, specifying the MIN, MAX, or DEF parameter causes the Product to respond
with the minimum, maximum, or default setting respectively.
• For set commands, specifying the MIN, MAX, or DEF parameters causes the Product to use the
minimum, maximum, or default setting respectively.
• | indicates alternate parameter values.
