Before installation:

Read this manual completely and gather all information on the unit. Make sure that
you understand it fully. Check that your application does not exceed the safe oper­ating specifications for this unit.

This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is

restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be

possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.

This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section).

Before mounting, using or removing this unit:

Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.

Care recommendations

Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.

This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause

damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-

proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical

part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo dis-

tributor office or Westermo Tech support.
A readily accessible disconnect device shall be incorporated external to the equipment.
This unit may have hot surfaces when used in high ambient temperature.

Description

The DDW-222 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. Also included are a RS-232 serial adapter and a 10-port Virtual Com
re-director software. The protocols used for network communication is UDP or TCP.
This allows the serial interface to be setup as a TCP-server or -client as well as an UDP
unit. 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-222 makes it possible to communicate over
10 km (6.2 miles) on twisted pair cable.
The DDW-222 is a bridge not router and so is simple to install. All configuration is done
using a web interface. The DIN rail mounted DDW-222 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.

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.

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-222 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.

Connect DSL 1 to DSL 2 on the following units to obtain a chain of linked units.

IP configuration

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.

1. Click the listed DDW-2XX that you wish to re-configure.

2. A pop-up screen will show with the message “Access switch via web”.

Figure 2

Click Cancel, figure 2.

3. Enter the preferred IP address, Subnet mask and IP gateway address, figure 3.
Click Set-button to confirm the settings in the unit, figure 3.
Click the Scan for switches button again and the settings you configured will appear in

the list. Now you can access the DDW-2XX via the browser for further configuration
by clicking the unit with an IP address that fits your subnet. Figure 2 will appear and now
you click the OK button and a web browser will be opened and redirected to the DDW­2XX unit login page, figure 5.

Click the Close button to get back to main view.
You will then be asked if you would like to quit.
Click the OK button, figure 4, and you will be
back to the main view of the IP Configuration
program (see figure 1).

Simple Network Management Protocol (SNMP)

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.
