IEEE INTERFACE OPTION
6.1 Introduction
The IEEE interface option makes the
PRS-300 a IEEE-488.2-1987 and SCPI 1994.0
compatible instrument. The PRS-300 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 program-
mable 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; con-
sult IET for additional information. A software
GPIB “keyboard” can be found at www.ietlabs.

6.2 Capabilities
The IEEE option provides remote control
over all functions except
POWER
. The IEEE
option responds to all Basic Commands in Ap-
pendix 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 ad-
dress 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
fi
nds
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 control-
lers.
To implement, request a download of
ICS_GPIBkybd_Install.zip
from IET Labs
Tech Support.
