Westermo’s DDW-242 and DDW-242-485 industrial Ethernet line extenders are used to establish long-distance, high-speed remote connections between simple or complex Ethernet networks using existing copper cables. The DDW-242 and DDW-242-485 are designed to operate in extreme industrial environments, which makes them suitable for mission-critical applications. The devices have an operating temperature range of -40 to +70 C, and have been tested to meet electromagnetic compatibility (EMC), isolation, vibration and shock standards. The line extenders enable Ethernet networks to be connected over distances of up to 15km, at data rates up to 15.3 Mbit/s on a single twisted pair cable. An integral switch allows two Ethernet devices to be attached, and a choice of either 232 or 485 serial port enables legacy equipment to be incorporated into the IP network. The devices include a built-in port-based firewall securing data between trusted and un-trusted networks. The WeOS operating system also provides advanced switching and routing functionality that enables complex industrial networks to be managed.
