Commands

Remote Operation

Programming Syntax

A command is composed of a header, any associated data, and a terminator. The header is the mnemonic or mnemonics that represent the operation to be performed by the switch driver. The different types of headers are discussed in the following paragraphs.

Compound Command Header

Compound command headers are a combination of two or more program mnemonics. The first mnemonic selects the subsystem, and the last mnemonic selects the function within that subsystem. Additional mnemonics appear between the subsystem mnemonic and the function mnemonic when there are additional levels within the subsystem that must be transversed. The mnemonics within the compound message are separated by colons.

Example To execute a single function within a subsystem:

:<subsystem>:<function><separator><program data><terminator>

ROUTE:GROUP <group name>:AUTOSELECT:OFF;

Example To transverse down a level of a subsystem to execute a subsystem within that subsystem:

:<subsystem>:<subsystem>:<function><separator><program data> <terminator>

ROUTE:GROUP:LABEL “Atten 0 to 110 dB by 10 dB steps”;

Selecting Multiple Subsystems

You can send multiple program commands and program queries for different switch driver subsystems on the same line by separating each command with a semicolon.

Example The colon following the semicolon enables you to enter a new subsystem.

:<subsystem>:<function><separator><data>;

<function><separator><data><terminator>

ROUTE:DRIVE:OFF:ALL;:SYSTEM:VERSION?

Common Command Header

Common command headers control IEEE 488.2 functions within the switch driver (such as clear status, etc.). Their syntax is:

*<command header><terminator>

No space or separator is allowed between the asterisk and the command header.
