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.
The VISA standard [1] includes specifications for communication with resources (usually, but not always, instruments) over T&M-specific I/O interfaces such as GPIB and VXI. There are also some specifications for T&M-specific protocols over PC-standard I/O, such as HiSLIP [2] or VXI-11 [3] (over TCP/IP) and USBTMC [4] (over USB).
The “synchronous channel” carries normal bi-directional ASCII command traffic (e.g., SCPI), and synchronous GPIB meta-messages (END, triggers, etc.). The “asynchronous channel” carries GPIB-like meta-messages that need to be treated at higher priority and independent of the data path (e.g., device clear, service request).
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
USB was designed to standardize the connection of peripherals to personal computers, both to exchange data and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on various devices.
While it was originally created for the IEEE-488.1 (GPIB) bus, [5] SCPI can also be used with RS-232, RS-422, RS-485, USB, Ethernet, VXIbus, HiSLIP, etc. [5] SCPI commands are ASCII textual strings, [5] which are sent to the instrument over the physical layer. [5] Commands are a series of one or more keywords, many of which take parameters.
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
Users interface to hardware by either writing direct bus commands (USB, GPIB, Serial) or using high-level, device-specific drivers that provide native "G" function nodes for controlling the device. National Instruments makes thousands of device drivers available for download on their Instrument Driver Network (IDNet). [10]
