2.6. RJ45 Ports: Signal Description

The RS900GP has several 10/100BaseTX ports that allow connection to standard CAT-5 UTP cable with RJ45 male connectors. The RJ45 receptacles are directly connected to the chassis ground on the unit and can accept shielded CAT-5 cables. If shielded cables are used, care must be taken to ensure the shielded cables do not form a ground loop via the shield wire and the RJ45 receptacles at either end.

Table 2.2. RJ45 Ethernet Pin Assignment

RuggedCom does not recommend the use of CAT-5 cabling of any length for critical real-time substation automation applications. However, transient suppression circuitry is present on all copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1 conformance. This means that during the transient event communications errors or interruptions may occur but recovery is automatic.

RuggedCom also does not recommended to use these ports to interface to field devices across distances which could produce high levels of ground potential rise, (i.e. greater than 2500V) during line to ground fault conditions.
