WESTERMO DDW-226 INDUSTRIAL ETHERNET EXTENDER

DDW-226 Industrial Ethernet Extender - Wolverine series of Ethernet extenders allow cost effective Ethernet networks to be created over long distances at high data rates

Introduction

The DDW-226 is an Industrial Ethernet SHDSL extender with support for redundant rings. The redundant protocol can be used either on the SHDSL interface or on the Ethernet interface. Our unique FRNT (Fast Recovery of Network Topology) technology is the fastest protocol on the market to re-configure a network in the event of any failure of a link or hardware. Also included in the DDW-226 is a RS-232 serial adapter and a 10-port Virtual Com port re-director software. The unit supports TCP client, TCP server and UDP protocol modes allowing it to be used in a wide variety of applications.

The DDW-226 allows the cables of existing serial networks to be reused to create an Ethernet network while still allowing the legacy serial device to function on the new network. The DDW-226 Ethernet Extender is the ideal solution for extending your Ethernet network over copper

cables where in the past the only option would have been fibre. At shorter range the transfer rate will be as fast as 5.7 Mbit/s in both directions. Transmission distances up to 15 km are possible, however at a reduced data rate. The SHDSL transmission technology makes the DDW-226 perfect for the re-use of existing copper cable installations from older communications networks. The Ethernet Extender supports two SHDSL interfaces and can therefore be used to create a daisy chain or ring network.

The DDW-226 uses the Westermo WeOS operating system already employed in our range of RedFox industrial Routing Switches. Using WeOS provides the DDW-226 with all the advanced switching and routing functionality supported by the Redfox. These functions include VLAN support, Layer 3 switching, Static Routing, Firewall functions, IGMP Snooping, VPN support and SNMP V3.
