12 Network Configurations
Kingston Technology Company EtheRx User’s Guide - Rev. B00
Linear Bus Network
The typical network configuration for 10BASE2 networks is a Linear Bus
topology in which nodes are connected to the BNC connector via a thin coaxial
cable. This configuration allows 10BASE2 nodes to communicate with a
10BASE-T segment. A BNC 50Ω (Ohm) terminator must be attached to each
end of the trunk segment. One of the terminators must be grounded. The
purpose of the terminators is to terminate the network and block electrical
interference.

Horizontal Cascading
The EtheRx hubs can be horizontally cascaded to other hubs as long as the
Ethernet 5-4-3 Rule is met (Refer to page 11). This connection can be made
through the BNC port, AUI port (16-Port models only), 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 through or crossover cable types. Figure 3-3
below is an example of horizontal cascading using the KNE16TP/WG under
the Ethernet 5-4-3 rule.
