Operating and Maintenance Instructions  –  19

Programming Guide

The following programming instructions for the TB9 grating filter are intended for users who are
familiar with remote interfaces and how to send or receive messages over a device.

A detailed description of the GPIB interface is in 

ANSI/IEEE Std. 488.1-1987 IEEE Standard

Digital Interface for Programmable Instrumentation published by the Institute of Electrical and
Electronics Engineers.

There are two external interfaces for remote control of the TB9 filter: a GPIB parallel interface
and an RS232 serial interface. The TB9 grating filter accepts the same device dependent
commands—the commands that control the instrument—over either interface.

GPIB Interface

GPIB Interface Pin Assignment and Functions

The required GPIB pin assignment is shown in Figure 7 and the functions are listed in Table 6.
