What are the uses of the GPIB bus?

What are the uses of the GPIB bus?

GPIB – Designed specifically for test and measurement and instrument control applications, the General Purpose Interface Bus (GPIB) has been a robust and reliable communication bus for 30 years and is still going strong. Using a parallel bus, GPIB provides an instrumentation bus with low latency.

What kind of bus interface does EIA / tia-422 support?

EIA/TIA-422 define a Balanced (differential) interface; specifying a single, unidirectional driver with multiple receivers (up to 32). RS-422 will support Point-to-Point, Multi-Drop circuits, but not Multi-Point [EIA485].

How many devices can be connected to a bus interface?

Up to 32 transmitters and 32 receivers may be interconnected in any combination, including one driver and multiple receivers (multi-drop), or one receiver and multiple drivers. The maximum of 32 devices is defined based on the Unit Load [UL] of each device [12K ohms].

What was version 1 of the I2C bus?

The I2C-bus specification 1 PREFACE 1.1 Version 1.0 – 1992 This version of the 1992 I2C-bus specification includes the following modifications: •Programming of a slave address by software has been omitted. The realization of this feature is rather complicated and has not been used. •The “low-speed mode” has been omitted.

How is the IEEE-488 general purpose interface bus used?

IEEE-488 General purpose interface bus and appropriate protocol are widely used in hardware-software systems for the connection of PC and work station with measurement instruments (e.g. in data acquisition systems). The protocol was developed in 60s in Hewlett-Packard and its initial name was HPIB (Hewlett-Packard Interace Bus).

When did national instruments introduce the GPIb protocol?

GPIB (HS-488), so-called high-speed protocol, offered by National Instruments in 1996, allows increasing bus bandwidth up to 8 MB/s using standard cables and hardware base. For one operation “talker” is capable of sending as many data bytes as “listener” may accept, depending on the availability of free buffers.

How many wires are in a GPIB bus?

The bus consists of 24 wires (16 signal lines for data transfer: 8 straight and 8 return; 3 matching; 5 for the bus control) and configured in such a way that it can serve up to 15 clients with addresses from 0 till 30 inclusive (the devices addresses should be different).
