than mines susceptible to firedamp
3
Equipment category 3.
A category is the classification according to the required level of protection.
This unit ensures the requisite level of protection during normal operation and
is intended for use in areas in which explosive atmosphere caused by gases,
vapours, mists, or dust mixtures are unlikely to occure or, if they do occure, are
likely to do so only infrequently and for a short periode only.
GIndicates protection concerning explosive atmospheres caused by gases,
vapours or mists (G).
Ex Indicates that this unit is in conformity with relevant European Ex standard(s).
nA
Type of protection used.
This unit is a non-sparking device "nA" which is constructed to minimize the
risk of occurence of arcs or sparks capable of creating an ignition hazard during
conditions of normal operation.
IIC Gas group, a typical gas i hydrogen.
T4
Temperature class T4 (T4 = 135°C).
This unit is classified in accordance with its maximum surface temperature
(external and internal).
Gc
Equipment protection level Gc (EPL Gc).
Equipment for explosive gas atmospheres, having a "enhanced" level of protec-
tion, which is not a source of ignition in normal operation and which may have
some additional protection to ensure that it remains inactive as an ignition
source in the case of regular expected occurences. EPL Gc are analogous to the
ATEX Categories (Category 3 G = EPL Gc).

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 fibre.
At 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 depends on the cable characteristics, communication
reach with different cables can be calculated with DDW-tool
DDW-120 can be used in point-to-point applications or as start and termination unit
together with DDW-22x in a daisy-chain application.
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 establish-
ing a connection. CPE (Customer Premises Equipment) is the unit that initiates the con-
nection.

12 6621-2214
Getting started
The DDW-120 is easy to use and install, the units work in pairs, one as has to be config-
ured as CO (Central Office) and one as CPE (Customer Premises Equipment). This con-
figuration 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 terminal 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 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.
Depending on the quality of the line and the distance there is possibility to select auto-
baud function.
This is done via DIP switches in the unit configured as CO.
Factory default is autobaud, reliable mode.
Note! Before connection and installation one of the connecting units have to be
reconfigured as a CO, see DIP-switch S1:4.
Note!
If the DSL link is not established, the speed might be set to high for the distance.

6621-2214
Diagnostic information
The DDW-120 can display diagnostic information on two way:
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.

If a customer supervision system is used the DDW-120 can provide with diagnostic
status.
The DDW-120 support
Data rate: 115.2 kbit/s
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None
The unit is responing to two commandon
1) DIAG
2) RUNDIAG
Information from DIAG command
• Software release
• DIP switch settings
• If the unit is configured as CO or CPE
• If the unit is configured for Annex A or Annex B
• DSL link state
• DSL data rate (bit/s)
• DSL noise margin (dB)
• Ethetnet data rate
• Ethernet duplex
Information from RUNDIAG command
• DSL link state
• DSL Data rate (bit/s)
• DSL Noise margin (dB)
The DDW-120 is ready for commando then prompt “DDW” is transmitted to
supervisor system.
The commando RUNDIAG will continuously send the information. Approx update with
1s base. Commando is aborted by sending “any key to abort”.

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
