Coax Interface

  
The Zebra Coax Interface permits the Zebra R-140, 105SL, and XiII/XiIII/XiIIIPlus Series printers to communicate with an IBM 3270 Mainframe, or associated controller. It provides IMB 3287, Model 2, printer compatibility including LU1 (SCS) and LU3 (3270 data stream) modes.

Coaxial Cable is a high frequency connecting cable in which an insulated wire runs through the middle of the cable. Surrounding the insulated wire is a second wire made of solid or mesh metal.

It is called "coaxial" because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by another concentric physical channel, both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters, can carry information for a great distance.

Coaxial cables are required for high-bandwidth broadband systems and for fast baseband systems, such as Ethernet.
