GPIBn

GPIBn, also known as General Purpose Interface Bus, is a standard for connecting electronic devices to computers and other devices. It was developed by the Hewlett-Packard Company in the 1960s and has since become widely used in various industries, including electronics, telecommunications, and scientific research. The standard defines a parallel bus that allows multiple devices to communicate with each other, with one device acting as the controller and others as listeners or talkers.

The GPIBn standard specifies the electrical and mechanical characteristics of the bus, as well as the communication protocol. It uses an 8-bit parallel data path and supports data transfer rates up to 1 Mbyte per second. The bus can connect up to 15 devices, with one device acting as the controller and the others as listeners or talkers. The controller initiates communication and can address each device individually.

GPIBn has several advantages over other communication standards, including its ability to connect multiple devices to a single bus, its high data transfer rates, and its ability to support a wide range of devices. However, it also has some limitations, including its relatively short cable length and its susceptibility to electromagnetic interference.

GPIBn has been largely replaced by more modern communication standards, such as USB and Ethernet, in many applications. However, it remains in use in some legacy systems and in applications where its unique features are required.
