General Purpose Interface Bus (GPIB) or Hewlett-Packard Interface Bus (HP-IB) is a short-range digital communications 8-bit parallel multi-master interface bus specification originally developed by Hewlett-Packard and standardized in IEEE 488.1-2003. It subsequently became the subject of several standards.

Easy-to-understand overview of GPIB communication, explanation of terminology, and basic knowledge regarding GPIB required for programming. What is GPIB? GPIB (General Purpose Interface Bus) was developed as an interface between computers and measuring instruments. It is mainly used to connect PCs and measuring instruments.

The GPIB interface, sometimes called the General Purpose Interface Bus (GPIB), is a general purpose digital interface system that can be used to transfer data between two or more devices. It is particularly wellsuited for interconnecting computers and instruments.

May 27, 2022 · What is GPIB or IEEE 488 Bus? The IEEE 488 (GPIB) bus is an 8-bit parallel multi-master interface bus that is used for short-distance communications. As the bus became the key interface meeting multiple standards, it was termed as General Purpose Interface Bus.

Jun 7, 2023 · GPIB is an 8-bit parallel interface employing 16 signal lines and eight return (ground) lines. Figure 1 shows the connector and pin numbers, signal names, and signal descriptions. The GPIB interface includes eight bidirectional data lines (orange), five bus-management lines (blue), three handshake lines (red), and eight ground lines (gray).

Today, the name G eneral P urpose I nterface B us (GPIB) is more widely used than HP-IB. ANSI/IEEE 488.2 -1987 strengthened the original standard by defining precisely how controllers and instruments communicate.

IEEE 488, also known as the General-Purpose Interface Bus (GPIB), provides high-speed parallel communication using a 24-pin connector. An IEEE 488 cable generally has eight single wires for data transfer, eight twisted-pairs for interface handshaking and management, and a drain (ground) wire, all enclosed in an insulating protective jacket.

Nov 13, 2018 · The IEEE-488 standard interface bus, popularly known as GPIB (General Purpose Interface Bus), was originally developed by Hewlett-Packard to allow maximum flexibility in data transfer between various laboratory instruments and their computers.

What is a GPIB? General Purpose Interface Bus: A standard bus for controlling electronic instruments with a computer. Also called IEEE-488 bus because it is defined by ANSI/IEEE Standards 488-1978, and 488.2-1987. Also called HP-IB, a trademarked term of Hewlett-Packard, which invented the protocol.

Mar 4, 2024 · IEEE-488 bus is a standard 8-bit, bidirectional, asynchronous bus (HP-IB) that enables a number of HP-IB compatible instruments to communicate with a controlling computer & with one another.
