IEEE INTERFACE
6.1 Introduction
The PRS-330 is a IEEE-488.2-1987 and SCPI
1994.0 compatible instrument. The PRS-330
IEEE-488 interface is based upon the ICS
Ethernet/GPIB/USB to Serial Interface Card.
More information can be found at www.icselect.
com on the 9006 Ethernet/GPIB/USB to Serial
Interface Card.
The IEEE STD 488.2 covers the electrical and
mechanical bus speci
fi cations, and state diagrams
for each GPIB bus function. It also establishes
data formats, common commands for each 488.2
device and controller protocols. The standard is
available on-line at http://www.ieee.org.
The SCPI standard provides a tree like series
of standard commands for programmable
instruments so that similar instruments by
different manufacturers can be controlled by the
same program. SCPI information and a command
reference are located in Appendix A.
Other tutorials are available on-line; consult IET
for additional information. A software GPIB
“keyboard” can be found at www.ietlabs.com
6.2 Capabilities
The IEEE option provides remote control over
all functions except
POWER . The IEEE option
responds to all Basic Commands in Appendix
B and all IEEE.2 Mandated common commands
in Appendix A.
6.3 Address Switch and Communications
Settings
The default GPIB address is 4. This address can
be changed remotely by sending the command
SYSTem:ADDR <n> where n is 0 - 30.
6.4 GPIB Test Keyboard
To aid the user in operating the PRS, a GPIB
“Keyboard” Controller program - the easiest
way to control GPIB devices without writing
a program - is available from IET. This GPIB
Keyboard program automatically finds your
device at start-up and it lets you enter just the data
that you want to send to the device. This program
works with ICS, Measurement Computing and
National Instruments controllers.
To implement, request a download of ICS_
GPIBkybd_Install.zip from IET Labs Tech
Support.
