This project defines a serial, full-duplex, asynchronous, 9-pin DTE communications port that follows EIA 574 and related standards. Portions of several standards will be referenced along with specific extensions applying to programmable instruments. The resulting draft will apply to point-to-point instrument systems composed of a measurement, stimulus or interconnect device and an instrumentation controller. It may also apply to certain devices outside the scope of the instrument system… read more environment. The document will cover mechanical, electrical and functional requirements of the interface. read less

This standard describes a series of mandatory and optional programming instructions and associated data registers that define a standard methodology for accessing and configuring programmable devices. These additional registers and instructions extend the capabilities of devices that comply with IEEE Std 1149.1TM - 2001 such that the IEEE Std 1149.1-2001 Test Access Port may be used for configuration activities. A data description format and extensions to Boundary-Scan Description Language (… read more BSDL) are also specified that provide for the development of standardized automation tools for device programming. read less

This standard will build on the interface functions defined in IEEE Std. 488.1-1987 to define a set of interface functions that will enable higher transfer rates between devices adhering to this specification while still maintaining the ability for these devices to communicate with existing IEEE Std. 488.1 devices. Topics within the scope of this standard include: Extensions to the interface functions defined in IEEE Std. 488.1; Definition of new interface functions; Possible extensions to the… read more remote message codes defined in IEEE Std. 488.1; Guidelines for calculating delays required to implement the new protocol at different distances. read less

This standard serves to amplify criteria in IEEE Std 603(TM)-2009, to address the use of programmable digital devices as part of safety systems in nuclear power generating stations. The criteria contained herein, in conjunction with criteria in IEEE Std 603-2009, establish minimum functional and design requirements for programmable digital devices used as components of a safety system.

This standard applies to interface systems used to interconnect both programmable and nonprogrammable electronic measuring apparatus with other apparatus and accessories necessary to assemble instrumentation systems. It applies to the interface of instrumentation systems, or portions of them, in which the a) Data exchanged among the interconnected apparatus is digital (as distinct from analog) b) Number of devices that may be interconnected by one contiguous bus does not exceed 15 c) Total… read more transmission path lengths over the interconnecting cables does not exceed 20 m d) Data rate among devices does not exceed 8 000 000 B/s. The basic functional specifications of this standard may be used in digital interface applications that require longer distances, more devices, increased noise immunity, or combinations of these. Different electrical and mechanical specifications may be required (for example, symmetrical circuit configurations, high threshold logic, special connectors, or cable configurations) for these extended applications. read less

This standard specifies a set of codes and formats to be used by devices connected via the IEEE 488.1 bus. This standard also defines communication protocols necessary to effect application independent device-dependent message exchanges and further defines common commands and characteristics useful in instrument system applications. This standard is intended to apply directly to small-scale to medium-scale instrument systems. It applies to systems comprised mainly of measurement, stimulus, and… read more interconnect devices with an instrumentation controller. The standard may also apply to certain devices outside the scope of the instrument system environment. As well as defining a variety of device-dependent messages, this standard extends and further interprets certain interface functions contained in IEEE Std 488.1 while remaining compatible with that standard. read less
