front port

A special cable is requested to connect two physical Ethernet interfaces together

without a hub, router, bridge or switch in between. The Tx and Rx signal wires

must be crossed in the cable to connect Tx with Rx on the other side and vice

versa. These cables are known as null-modem cable or cross-wired cable. The

minimum length should be about 2 m. The connector type is RJ-45, see

IED

Point to point link between IED and PCM600 using a null-modem

cable

The following description is an example valid for standard PCs using Microsoft

Windows operating system. The example is taken from a Laptop with one Ethernet

interface.

Administrator rights are requested to change the PC communication

setup. Some PCs have the feature to automatically detect that Tx

signals from the IED are received on the Tx pin on the PC. Thus

straight (standard) Ethernet cable can be used.

The IEDs DHCP server for the front port assigns an IP address for the computer.

The computer must be configured to obtain its IP address automatically as

described in the following procedure.
