Copper Ethernet Ports
The RUGGEDCOM RSG2288 supports several 10/100/1000Base-TX Ethernet ports
that allow connection to standard Category 5 (CAT-5) unshielded twisted-pair (UTP)
cables with either RJ45 male connectors. The RJ45 connectors are directly connected
to the chassis ground on the device and can accept CAT-5 shielded twisted-pair (STP)
cables.
WARNING
Electric shock hazard – risk of serious personal injury and/or equipment
interference
If shielded cables are used, make sure the shielded cables do not form a ground loop
via the shield wire and the RJ45 receptacles at either end. Ground loops can cause
excessive noise and interference, but more importantly, create a potential shock
hazard that can result in serious injury.
Pin-Out
The following is the pin-out description for the RJ45 connectors:
