COMMUNICATIONS SETUP
When looking at this connector, pin 1 is at the left,
and pin 8 is at the right.
THE HUB
A Hub is a common connection point for devices in a
network. Hubs are commonly used to connect
segments of a LAN (Local Area Network). A hub
contains multiple ports. When a data packet arrives at
one port, it is copied to the other ports so that all
segments of the LAN can see all packets.
THE SWITCH
Network Switches look nearly identical to hubs, but a
switch generally contains more intelligence than a
hub. Unlike hubs, network switches are capable of
inspecting the data packets as they are received,
determining the source and destination device of that
packet, and forwarding that packet appropriately. By
delivering messages only to the connected device
that it was intended for, network switches conserve
network bandwidth and offer generally better
performance than hubs.
The Switch takes the signal from each
computer/Quantum™ LX and sends it to all of the
other computers/Quantum’s in your plant or office.
Switches come in several sizes, noted by the number
of ports available -- a four-port Switch can connect
four computers, an eight-port Switch can connect up
to eight computers and so on. So, if you start with a
four-port Switch but eventually add more Quantum’s,
you can buy another Switch and connect it to the one
you already have, increasing the potential number of
Quantum’s on your network.
Typical Switch
Note: If you want to connect one computer to
one Quantum™, you can avoid the switch and
use a crossover Cat 5 cable. With a crossover
cable, you directly connect one Ethernet device
to the other without a Switch. To connect more
than two you need a Switch. Refer to the
following pictorial to construct a crossover cable.

Because of the large number of possible
configurations in an Ethernet network, you most likely
will not have any type of automated installation
software. This means that you will need to manually
configure all the options. To configure these options
for the Quantum™, please refer to the section in this
manual entitled Internet Setup.
