It is aIn-Line / Lineardigital interface for programmable instrumentation utilizingConfigurationa parallel bus that permits multiple devices to bePrinter Plotter Scannerinterconnected. A GPIB bus can be configured as a physicalstar, tree, in-line (linear), or a combination of these.Adapter: A device used to interconnect two differentconnector types.American Wire Gauge (AWG): A U.S. standard set of non-ferrous wire conductor sizes. Typical data wiring is AWGnumber 24, 26 or 28. The higher the gauge number, thesmaller the diameter and the thinner the wire.Backshell (Hood): A mechanical backing that is sometimesput onto a connector. The device protects the conductorsand can be assembled or injection molded.Bus: Also called a "Daisy Chain". A network topology where Physical / Stareach node is connected to one another in line. A major Configurationdisadvantage is that when there is a break in the bus theentire network goes down.Cable: A set of insulated wires or conductors within anextruded jacket. Many types of cable utilize shielding aroundthe wires and under the cable jacket.Cable Assembly: A piece of cable that has been terminatedwith one or more connectors.Conductor: A metal path (usually copper) that passeselectricity. When discussing data cabling, "wire" ...
