Ethernet Wiring
These switches provide connections to Ethernet devices on the battlefield. Typically a port
is used to connect to another Ethernet switch or hub that is connected to the main Ethernet
backbone. The other Ethernet ports are then connected to Ethernet devices such as
communication systems, Ethernet I/O, or industrial computers. Electrical isolation is
provided on the Ethernet ports for increased reliability.
lease follow normal Ethernet wiring practices when installing these switches.
P
Use data-quality (not voice-quality) twisted pair cable rated category 5 (or better) with
standard RJ45 connectors. You can use all standard existing RJ45 Cat5e cordset and
transform it into an environmental connector, without any cabling operation, and without
any tool!
Please note that these cables are available as straight-thru or cross-over configurations.
Either type can be used because these switches support auto-mdi/mdix-crossover. For
reference, the pin-outs of the two cable types are listed below.

Note: Hubs and switches are different devices. Hubs simply broadcast all messages
out all ports. switches intelligently route messages only out the appropriate port.
