GPIB (General Purpose Interface Bus) interface is also known as IEEE 488.
The original 488.1 specification defines the mechanical and electrical
characteristics of the interface and its fundamental protocols.
The 488.2 specification defines a minimum configuration, and adds
specifications for a basic set of instrument commands and common data
formats.
In order to communicate with the power supply over GPIB interface, a
GPIB interface card must be placed in the computer.
A GPIB system allows interconnection of instruments and other devices to a
controlling computer.
Here are some specifications of IEEE 488.1:

§
Up to 15 devices may be interconnected in a GPIB network
Configuration of the bus network may be linear or bus
24 bus lines: 8 data lines, 8 control and management lines, 8 GND
lines
Data transfer mode: 8-bit parallel
Handshake: '3 wire handshake'; reception of each data byte is
acknowledged.
total transmission path length: 20m, or L < 2N
L – total transmission path length
N – nu mber of devices
Maximum transmission rate: 1 megabyte per second. The actual
data rate is determined by the slowest device.
Each device connected to the interface must have a unique address
between 0 to 30 (decimal value).
