Detailed information about each command is given below. Functionality is continually being added to each
command and the feature is denoted by a firmware version where it first appears.

A table listing valid values follows the syntax of each command. Default values appear in boldface type.
The syntax of each command is presented in terms of what is required and what is optional. Every
command must be enclosed in curly brackets, “{“ and “}”. The command # and the option parameters are
comma delimited.

Syntax: { command #, [option [,option…]] }

The command # represents the command to be issued to LabPro. The reset command has the simplest
syntax: s{0}.

[option] indicates an optional parameter. In many instances, using one optional parameter requires
additional optional parameters be specified. The channel setup command is a good example. It can take
one, two or five optional parameters.
