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

SAFETY DURING INSTALLATION
The product must be installed by qualified service personnel and built into an apparatus cabinet or similar, where access is restricted to service personnel only.
During installation, ensure a protective earthing conductor is first connected to the protective earthing terminal (only valid for metallic housings). Westermo recommends a cross-sectional area of at least 4 mm2.
If the product does not have a protective earthing terminal, then the DIN-rail must be connected to the protective earth. Upon removal of the product, ensure that the protective earthing conductor, or the connection to earth via the DIN-rail, is disconnected last.

HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur when connected to a power supply.

PROTECTIVE FUSE
It must be possible to disconnect manually from the power supply. Ensure compliance with national installation regulations. Replacing the internal fuse must only be performed by Westermo qualified personnel.

REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords with a cable diameter of AWG 26 or larger. Regarding power cable dimensions, see Interface Specifications.

ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damage to internal electronic parts by discharging your body to a grounding point (e.g. use a wrist strap).

Care recommendations
Follow the care recommendations below to maintain the full operation of the product and fulfill the warranty obligations:

Do not drop, knock or shake the product. Rough handling above the specification may cause damage to internal circuit boards.
Use a dry or slightly water-damp cloth to clean the product. Do not use harsh chemicals, cleaning solvents, or strong detergents.
Do not paint the product. Paint can clog the product and prevent proper operation.

Description

Functional description

The DDW-120 Ethernet Extender is the ideal solution for extending your Ethernet network over copper cables where in the past the only option would have been fiber.
At a shorter range, the transfer rate will be as fast as 15.3 Mbit/s in both directions.
Depending on the quality of the cables distances up to 15 km are possible.
DDW-120 is transparent for multicast addressing, VLAN packets, VPN pass-through for IPSec, and for protocols like MODBUS/TCP and Profinet. The Link Fault Forward LFF) functionality in DDW-120 forwards information about the Ethernet link status, this is sent over the SHDSL link between two DDW-120 units. In many applications, it is a requirement to disconnect the link on the other side of the SHDSL link if the primary Ethernet link goes down.
The units will auto-negotiate the transmission speed but can also be forced to choose a slower (more reliable) or faster (less reliable) data rate.
Communication speed and distance depend on the cable characteristics, communication reach with different cables can be calculated with DDW-tool
DDW-120 has dual power input in case power supply redundancy is needed. In case only one power source is connected the unit will still operate according to specification.
DDW-120 can be used in point-to-point applications or as a start and termination unit together with other Wolverine products in daisy-chain applications.
Description of used nomenclature:
Noise margin:
The margin between signal and noise (dB)
CO/CPE:
CO (Central Office) answering central unit, the CO configures the CPE when establishing a connection. CPE (Customer Premises Equipment) is the unit that initiates the connection.

Getting started

The DDW-120 is easy to use and install, the units work in pairs, one has to be configured as CO (Central Office) and one as CPE (Customer Premises Equipment). This configuration is made with DIP switches situated under the lid of the DDW-120.

Connect the SHDSL Line
1) Connect the twisted pair to DSL screw terminals 1 and 2 (polarity independent) situated at the base of the DDW-120.
Connect the Ethernet Line
Connect Ethernet to the TX port on the front of the DDW-120.
The factory settings for the DDW-120 is plug and play mode where the TX port is enabled for:
Ethernet Auto-negotiation enabled.
Auto MDI/MDI-X.
Auto-polarity enabled.
The DDW-120 will automatically sense the data rate of the connected unit and cable type.
Settings in the units
The units operate in pairs, one as CO (Central Office) and one as CPE (Customer Premises Equipment). Factory setting in the DDW-120 is as CPE.
Note! Before connection and installation, one of the connecting units has to be reconfigured as a CO, see DIP-switch S1:4.
Depending on the quality of the line and the distance there is the possibility to select the autobaud function.
This is done via DIP switches in the unit configured as CO. Factory default is autobaud, reliable mode.
Note! If the DSL link is not established, the speed might be set too high for the distance.

Diagnostic information

The DDW-120 can display diagnostic information in two ways:
1) Using the Westermo diagnostic tool DDWtool.exe.
2) Using a terminal program.

Using DDW-tool
1) Connect the standard cable 1211-2027 to the diagnostic port, located under the lid of DDW-120.
2) Choose the corresponding Com port in the drop list of the tool. The tool will try to find the port used by the debug cable.
3) Click the button connect, if the correct com port is selected DDW-tool will be updated with actual status online information.

* To minimize the risk of interference, a shielded cable is recommended when the cable is located inside the 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.
