5.2.2. Syntax Conventions

The following outlines the proper syntax of the commands for the

488.2 protocol:

•

Words in the format XXXxxxxx represent keywords. The upper case

part is required; the lower case part is optional. Any combination

of upper and lower case characters is acceptable (example:

CONnect - the CON is required and minimally acceptable).

• Italicized words represent values (example: output)

• [ ] represents optional words or combinations, | means that a

choice can be made among the possibilities.

• Numbers must be whole numbers in base 10. Leading zeros are

ignored. As a departure from the 488.2 protocol, decimal

numbers, scientific notation and arithmetic expressions are not

accepted.

• Where spaces are shown, at least one space must appear unless

there's a comma. An arbitrary number of spaces can be used in

addition to the required one.

• A "compound" command may be formed by placing a ;

between commands.

• A command must be terminated with the ASCII linefeed

character (0x0a, 10, or Ctrl-J).

• Responses are sent only in reply to queries (commands which end

with “?”).

The switching mode for the system may be enabled in AUTO-

ROUTE or GANGED mode. AUTO-ROUTE mode does not need the

“MODule” parameter in the command syntax for the following

commands:

• CONnect

• DISconnect

• QUEry

MODES, please refer to the REMOTE CONTROL INFORMATION
