Communication Ports Wiring
Overview
The industrial Ethernet switches and media converters provide connections to standard
Ethernet devices such as PLCs, Ethernet I/O, industrial computers and much more. RJ45
(copper) Ethernet ports and fiber optic Ethernet ports are available depending on model.
RJ45 Ethernet Wiring
Use data-quality (not voice-quality) twisted pair cable rated category 5e (or better) with
standard RJ45 connectors. Straight-through or crossover Ethernet cable can be used for all
devices the switch is connected to because all the ports are capable of auto-mdi/mdix-crossover
detection.
The RJ45 Ethernet port connector bodies on these products are metallic and connected to the
Chassis GND terminal. Therefore, shielded cables may be used to provide further protection.
To prevent ground loops, the cable shield should be tied to the metal connector body at one
end of the cable only. Electrical isolation is also provided on the Ethernet ports for increased
reliability.
NOTE: For reference only. Either cable wiring will work.
RJ45 Cable Distance
The maximum cable length for 10/100BaseT is 100 meters (328 ft.).
