4.1 Copper Ethernet Ports
The RUGGEDCOM RS969 supports eight 10/100Base-TX Ethernet ports that allow
connection to standard Category 5 (CAT-5) unshielded twisted-pair (UTP) cables
with RJ45 male connectors or M12 male connectors. The RJ45/M12 connectors are
directly connected to 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/M12 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.
