Appendix A

Remote Operating Procedures

The following instructions explain how to use the GPIB feature to remotely control

the calorimeter. All front panel key functions, except the display ON/OFF, can be

controlled via the GPIB. Before proceeding with the remote operating procedures

make sure you are throughly familiar with the normal operating procedures of this

equipment.

Sample GPIB program statements are included for two of the more common GPIB

controllers; National GPIB-PCII and Hewlett Packard Model 9000, Series 200/300.

The National GPIB-PC is a controller card that installs into an expansion slot of an

IBM PC/XT/AT or compatible computer. The HP 9000, Series 200/300 is a stand

alone scientific computer. In each sample statement, it is assumed that the device ad-

dress code is set to 24.

All sample statements are presented in the BASIC/BASICA programming language.

For National GPIB-PC programs, UD% is the Calorimeter unit descriptor and BRD%

is the controller card descriptor. Consult National GPIB-PCII documentation for

more information about the UD% and BRD% descriptors.

GPIB Overview The general purpose interface bus (GPIB) is a standard cable for parallel control of

electronic equipment. Up to 15 pieces of equipment can be controlled and monitored

for automated testing or data retrieval. A GPIB controller, usually a computer, is

used to take over instrument controls and retrieve measurement data.

GPIB Capabilities The Calorimeter's GPIB capabilities comply with the requirements of IEEE-488

1978, Standard Digital Interface For Programmable Instrumentation. Table 6 lists

the GPIB capabilities supported by the calorimeter.
