Addressing the Switch Driver

Remote Operation

Programming Syntax

Since GPIB can address multiple devices through the same interface card, the device selector passed with the program message must include not only the correct interface code, but also the correct instrument address.

Interface Select Code (Selects Interface)

Each interface card has a unique interface select code. This code is used by the controller to direct commands and communications to the proper interface. The default is typically 7 for GPIB controllers.

Instrument Address (Selects Instrument)

Each instrument on an GPIB bus must have a unique instrument address between decimal 0 and 30. The address must not be the address of the controller. (Refer to Chapter 2, “Installing the 87130A Attenuator/Switch Driver.”) The device address passed with the program message must include both the correct instrument address and the correct interface select code.

Example DEVICE SELECTOR = (Interface Select Code x 100) + (Instrument Address)

Program Message Syntax

If the instrument address for the switch driver is 9 and the interface select code is 7, when the program message is passed, the routine performs its function on the instrument at device selector 709.

For the switch driver, the instrument address is typically set to 9 at the factory. The program examples in this manual assume the switch driver is set to device address 709.

To program the switch driver over the bus, you must have an understanding of the command format and structure expected by the switch driver.

The switch driver is remotely programmed with program messages. These are composed of sequences of program message units, with each unit representing a program command or query.

A program command or query is composed of a sequence of functional elements that include separators (a blank space which is required to separate the program mnemonic from the program data), headers, program data, and terminators. These elements are sent to the switch driver over the system interface as a sequence of ASCII data messages.
