Introduction; Scope Of Manual; Chapter 1: The Ieee-488.2 Interface - TDK-Lambda Z+ series User Manual

The internal factory installed General Purpose Interface Bus (GPIB) allows operation of the Z
Supply from a computer via IEEE-488.
The interface allows the user complete remote control of the Power Supply, including output
voltage and current setting and monitoring, protection setting, trigger, waveform list operation,
Power Supply status and SRQ reporting.
Communication over the GPIB interface meets IEEE 488.2 standards for Programmable Instrumentation
(SCPI) compliant.
This manual contains the information needed to operate the optional embedded IEEE(GPIB)
Interface used in the Power Supply. It includes the following:
•
A general description of the GPIB.
•
Connection.
•
Configuration.
•
Listing and description of SCPI command.
•
Communication Example.
The IEEE-488 digital programming interface (also called the GPIB interface) is a popular way to
connect instruments to a computer. It uses a specialized 24-pin cable with connectors that allow
cables to be 'stacked' together. There are eight data wires; eight control wires and eight ground
wires. If the system runs from a personal computer, there are numerous vendors of IEEE controller
cards and software.
The IEEE-488 standard has gone through several upgrades. The IEEE-488.1 focused on the
handshaking of the eight control lines. The IEEE-488.2 added status registers inside each instrument
and it added common commands to make programming groups of instruments easier. The latest
specification, SCPI, adds guidelines for the command syntax so one vendor's Power Supply will
use the same commands as another's. The Interface follows all of these standards.
Because many instruments may be connected and independently controlled by a single IEEE
controller, each instrument must have a unique address. The IEEE controller automatically sets
its address equal to the Power Supply address.
