Ethernet Wiring
These switches provide connections to Ethernet devices on the factory floor. 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
PLCs, Ethernet I/O, or industrial computers. Electrical isolation is provided on the Ethernet
ports for increased reliability.
Please follow normal Ethernet wiring practices when installing these switches.
Note: All 5 ports on the 5-port switch and ports 1-8 on the 9-port switch support auto-speed & duplex
detection, auto-mdi/mdix-corssover and auto-polarity. Port 9 is an uplink port and will auto-speed and
crossover detect but require full duplex and the correct polarity.
Use data-quality (not voice-quality) twisted pair cable rated category 5 (or better) with
standard RJ45 connectors. For best performance use shielded cable. 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.
