RJ45 male connectors. The RJ45 receptacles 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.
