Description
The DDW-221 is an Industrial Ethernet SHDSL extender with support for redundancy.
The redundant protocol can be used ether on the SHDSL interface or on the built-in
Ethernet switch.
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.
SHDSL represents the best of several symmetric DSL technologies. This unit provides the
ability to reuse existing twisted copper pair with data rates from 192 kbit/s to 5.7 Mbit/s
in both directions. The DDW-221 makes it possible to communicate over 10 km
(6.2 miles) on twisted pair cable.
The DDW-221 is a bridge not router and so is simple to install. All configuration is done
using a web interface.
The DIN rail mounted DDW-221 is designed for harsh environments and can be used
in industrial and railway applications. It can be powered from two separate supplies and
handle an operating voltage range of 16 – 60 VDC.

** To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m
boundary to the rails and connected to this port. The cable shield should be properly connected (360°) to an
earthing point within 1 m from this port. This earthing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should
be connected to the earthing system of an installation and may be directly connected to the protective earth.
CAT 5 cable is recommended.
Unshielded (UTP) or shielded (STP) connectors
can be used.

In an SHDSL connection one unit shall be configured as CO (Central Office)
and one as CPE (Customer Premises Equipment). DDW-22x factory default is,
DSL1 configured as CPE and DSL2 configured as CO.
Redundant SHDSL connection
The DDW-221 are available with redundant ring technology. This eliminates
network failure caused by communication failures on the ring ports. In a ring
application one unit must be configured as focal point, all other units will be configured as members.

Configuration
The unit can easily be configured via the onboard Web based configuration tool. Local
IP addresses can also be configured by using the Westermo IP Config too. From the IP
Config tool it is then possible to browse into the unit for further configuration.
IP Address
When delivered, the default IP address of the DDW-2XX is 192.168.2.200.
The default gateway is 192.168.2.200
If the default address of the unit is valid in the connected network it is possible to access
the unit directly from a web browser.
Change local IP address
The local address of DDW-2XX can be configured using the IP Configuration tool.
The IP Configuration program is available on the CD or for download from the
WESTERMO web page: http://www.westermo.com, (choose Downloads/Software/
Ethernet/Ethernet switches/)
Name: setup.exe
Install the software and start the application from a PC on the network connected to
where the DDW-2XX is installed. Make sure that the Default IP of the configuration software (see figure below) is in the same subnet as your PC.
Note! If you are not sure about the subnet – consult your network administrator.
Note! IP Config version must be 10.0.0 or higher.
By clicking the Scan for switches button the IP Configuration Software will detect the
Westermo switches on the network. The software will list all Westermo managed switches or routers connected to the network. Information as in figure 1 will appear for each
detected unit connected to the same network as your PC.
If you only want to change the IP address and the subnet mask, this
can be done within the IP config tool.

The DDW-2XX supports Simple Network Management Protocol version 1 and 2c
(SNMPv1 and SNMPv2c). SNMP is an Internet standard protocol (IP) developed to
manage IP nodes (servers, workstations, routers, switches and hubs etc.) on an
Ethernet network.
SNMP enables network administrators and control engineers to manage network
performance, find and solve network problems, and plan for network growth.
The DDW-2XX MIB’s are divided into groups allowing the SNMP manager to poll
the SNMP agents for information.

Factory default
It is possible to set the unit to factory default settings by using two Ethernet cables and
connect to the unit.
To set the unit to factory default do the following:
1. Connect Ethernet cable from port 1 to port 4.
2. Connect Ethernet cable from port 2 to port 3.
3. Power up the unit.
4. Wait for the unit to start up. Control that the PWR led is flashing green.
The PWR flashing indicates that the unit will be set to factory default.
5. Remove the Ethernet cables, the unit will automatically start with factory
default settings.
Note! The Ethernet cables must be removed within 30 seconds from power up
or the unit will do a normal start up.
