hub through a coaxial cable.

Station Connections with
Twisted-Pair Cable

Connect each station to the Ethernet Hub by
means of a twisted-pair straight cable (10BaseT
cable, Category 3, 4, or 5). Plug one RJ-45
connector into a front-panel port of the Ethernet
Hub, and plug the other RJ-45 connector into the
station’s Ethernet adapter.
