Linear Bus Network

The typical network configuration for 10BASE2 networks is a Linear Bus

topology in which nodes are connected via thin coaxial cabling using the BNC

connector. A 50Ω (Ohm) terminator must be attached to each end of the trunk

segment and one of the terminators must be grounded. The maximum cable

length is 185M per segment. To minimize cable-related problems, do not mix

single filament (black PVC jacket) with stranded filament (DEC grey) coaxial

cables on the same network.

Horizontal Cascading

The EtheRx hubs can be horizontally cascaded to other hubs as long as the

Ethernet 5-4-3 Rule is met. This connection can be made through the BNC

port, AUI port, or one of the UTP ports. To cascade to another hub, use the

last UTP port which has a cascade switch to support either straight-thru or

crossover cable types. Figure 6 below is an example of horizontal cascading

using the KNE24TP/RS under the Ethernet 5-4-3 rule.
