4.10.2 Single Hub and Switched Connections
The next level of complexity is a single hub or switch system. Hubs and switches
are commonly available with any
where from 4 to 24 connections.
The multiple Ethernet ports on a hub allow physical star type network wiring. The
hub is typically placed in the center of the system. Individual cables are run
between the hub and each controller.
Crossovers are made internal to the hub. Therefore, in a single hub system, all
connections are straight-through. Remember that for 10Base-T, each cable
connection is limited to 100 meters in length.
