Alternately, internally single-terminated couplers (with or without the non-functional bus connectors) can be supplied. Even if only one non-terminated coupler acts as the bus because all devices (bus controller, remote terminals, etc.) are connected to the coupler stubs, the external bus connections of the coupler must be terminated.
Diagrams of different Parallel SCSI symbols [1]. Parallel SCSI is not a single standard, but a suite of closely related standards. There are a dozen SCSI interface names, most with ambiguous wording (like Fast SCSI, Fast Wide SCSI, Ultra SCSI, and Ultra Wide SCSI); three SCSI standards, each of which has a collection of modular, optional features; several different connector types; and three ...
At the two ends of the bus, resistors connect between the positive (high) and negative (low) signal wires either in internally terminated bus couplers or external connectorized terminators. The MIL-STD-1553B bus must be terminated at both ends to minimize the effects of signal reflections that can cause waveform distortion and disruption or ...
VPX computer bus standard - V -VME and P -PCI and X the extents for both buses standards. VXI: 1987 [13] 160 MByte/s [14] Multivendor standard for automated testing expansion cards. Working group is VXIConsortium.
The STEbus (also called the IEEE-1000 bus [1]) is a non-proprietary, processor-independent, computer bus with 8 data lines and 20 address lines. It was popular for industrial control systems in the late 1980s and early 1990s before the ubiquitous IBM PC dominated this market.
The NMEA 2000 network, like the SAE J1939 network on which it is based, is organized around a bus topology, and requires a single 120Ω termination resistor at each end of the bus. (The resistors are in parallel, so a properly terminated bus should have a total resistance of 60Ω). The maximum distance for any device from the bus is six metres.

The technology [2] uses two [a] sets of thick, multi-connector copper cables, one [b] set, carrying data, called the bus, and the other set, carrying control information, called the tag. [3] Bus and tag terminator blocks. Bus and Tag cables are "daisy chained"; and one interface can attach up to eight peripheral control units. The last control ...
