CHAPTER 7:
7.1

General

General Purpose Interface Bus (GPIB, also referred as IEEE), factory installed as an option, allows
operation of the
The interface allows the user a remote control of the power supply, including output voltage,
current setting and monitoring, protection setting, trigger, waveform list operation, power supply
status, SRQ reporting, and more.
Communication over the GPIB interface meets the IEEE 488.2 standard for Programmable
Instrumentation (SCPI) compliant.

IEEE-488.2 Interface

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.
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, identical to the power supply address.
For complete and specific information, refer to the following documents: ANSI/IEEE Std 488.1-1987
IEEE Standard Digital Interface for Programmable Instrumentation and ANSI/IEEE Std 488.2-1987
IEEE Standard Codes, Formats, Protocols and Common Commands.

• Each power supply must be configured to IEEE communication interface.
• Each unit must have a unique address, ranging from 0 to 31.
• Baud rate and language are automatically fixed to "115200" and "SCPI".
Address 31 must be avoided because it is used for special command messages.
