DDW-221 and DDW-222 have been added to Westermo’s Wolverine series of Ethernet extenders. They have all the same features as their predecessor, the DDW-220, but also provide integrated serial port and redundant rings support. The redundant protocol can be used either on the SHDSL interface or on the built-in Ethernet switch. It uses Westermo’s FRNT (Fast Recovery of Network Topology) technology, which is claimed to be the fastest protocol on the market to re-configure a network in the event of any link or hardware failure.
Further, the DDW-222 includes a RS-232 serial adapter and 10-port Virtual Com port re-director software which re-directs a Com port to an IP address. Pre-existing programs that use Com ports can then be reused in IP networks. The cables of existing serial networks can be reused to create an Ethernet network while still allowing the legacy serial device to function on the new network. The unit supports TCP client, TCP server and UDP protocol modes allowing it to be used in a wide variety of applications.
