Preparing for Use

What You'll Learn in This Chapter

This chapter tells you how to connect a computer to your instrument via the Hewlett-Packard

Interface Bus (HP-IB) or the RS-232 Interface and how to connect a printer or a plotter.The

remainder of the chapter covers procedures to follow if a problem is encountered.

Connecting Your Instrument to a Computer

The instrument works with many popular computers. However, the steps required to connect

your instrument to a specic computer depend on the computer you are using. Before turning

to the interconnection instructions for your computer, please read the following general

information.

All of the test programs for HP-IB and RS-232 interfaces are written using the BASIC language

of the computer under consideration. If you have never entered or run a BASIC program, refer

to your computer documentation.

Connecting the Computer to the Instrument

For the HP-IB Interface

Appendix A contains instructions for connecting the instrument's or to an HP Vectra PC

equipped with an HP 82300B BASIC Language Processor. If your computer is not listed, but

it supports an HP-IB interface, there is a good possibility that it can be connected to the

instrument. Consult your computer documentation to determine how to connect external

devices on the bus.

For the RS-232 Interface

Appendix B contains instructions for connecting the instrument's RS-232 interface to an

HP Vectra PC or IBM PC/AT or compatible computers. If your computer is not listed, but

it supports a standard RS-232 interface, there is a good possibility that the instrument may

be connected to the computer. Consult your computer documentation to determine how to

connect external devices to your computer's RS-232 connector.

Preparing for Use 1-1

There are two types of RS-232 devices: data terminal equipment (DTE) and data

communication equipment (DCE). Types of DTE devices include display terminals.DCE

equipment includes modems and, generally, other computer RS-232 devices. The instrument

RS-232 port is the DTE-type. Connections from the computer (DCE) to the instrument (DTE)

are shown in Figure 1-4.

Test Program

The program shown below works with the following computers:

HP Vectra PC using a version of BASIC (HP 45952A) for the Vectra PC. The MS BASIC

Interpreter (HP 35190A) is compatible with the version of BASIC for the Vectra PC.

IBM PC/AT and compatible computers using BASICA (version 2.0 or later) or GW BASIC.

To test the interconnection, rst load the BASIC language for your computer and specify a

communications buer of 4096 bytes. Use the following command:

BASICA/C:4096

Preparing for Use 1-9

Set the instrument baud rate to 1200, to match the baud rate set up for the computer port in

the test program. In line 20, the \1200" indicates 1200 baud for the computer port. Press the
