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 50
Ω (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.
