Programming Guide

The following programming instructions for the SB switch are intended for users who are
familiar with the GPIB interface and how to send or receive messages over a device. A
detailed description of the GPIB interface is contained in ANSI/IEEE Std. 488.1-1987 IEEE
Standard Digital Interface for Programmable Instrumentation , published by the Institute of
Electrical and Electronics Engineers.
The SB switch is equipped with a GPIB parallel interface and an RS232C serial interface. The
switch accepts the same device dependent commands (commands that control the instrument)
over either interface.
The SB switch can be set to emulate the interface command sets, status reporting, and service
request control of the SC Series and SX Series switches. The active interface command set is
displayed when the switch is powered on. See the Setting the Interface Command Set
section for instructions on changing the interface command set.

GPIB Pin Assignment

Caution
Tighten the connector lock screws by hand. Do not use a screwdriver.

Setting the GPIB Address

To display or edit the GPIB interface address:
1. Press the GPIB ADDR key to set the switch to GPIB mode. The current GPIB address is
displayed. (The factory-set GPIB address is 7.)
2. To change the address, press the
