Safety
Before using this unit:
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.
Hazardous voltage may occur within this unit when connected to power supply
or TNV circuits.
Prevent access to hazardous voltage by disconnecting the unit from power supply
and all other electrical connections.
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap).
Before installation:
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 Installation section).
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.

Description
Functional description
SHDSL represents the best of several symmetric DSL technologies that has been com-
bined into a single industry standard. DDW-100 is designed as a transparent Ethernet
Extender for 10/100BaseTX networks, it is transparent for multicast addressing, VLAN
packages, VPN pass through for IPSec and for protocols like MODBUS.
SHDSL provides the possibility to re-use existing twisted copper pair with data rates
from 192 Kbit/s to 2.3 Mbit/s in both directions (Symmetric DSL), according to standard
ITU-T G.991.2.
Based on the quality of the line and the communication speed the distance up to 6.5 km,
the distanse depends of the quality of the line and cable characteristics, this will differ
from application to application, therefore a unique feature is implemented for reliable
mode, high speed mode or normal mode.
Distance depending on speed without noise, cable type is AWG24

Getting started
DDW-100 is easy to use and install, the units work in pair, one as have to be configured
as CO (Central Office) and one as CPE (Customer Premises Equipment).This configura-
tion is made by DIP-switches placed under the lid in DDW-100.
Connect the SHDSL Line
There is two options for connecting the SHDSL line:
1) Connect the twisted pair to DSL screw terminal 1 and 2 (polarity independent)
placed in the bottom of DDW-100.
2) Connect the line through RJ-11 to the DSL line placed in the front of DDW-100.
Note! These two connections are parallel, it is not possible to use both at the same
time.
Connect the Ethernet Line
Connect Ethernet to the TX port placed in the front of DDW-100.
Factory settings for DDW-100 is plug and play mode where TX port is enabled for:
… Ethernet Auto-negotiation enabled.
… Auto MDI/MDI-X.
… Auto-polarity enabled.
DDW-100 will automatically sense the speed of the connected unit and if a crossed cable
is used.
Settings in the units
The units operates in pairs, one is working as CO (Central Office) and one as CPE
(Customer Premises Equipment). Factory setting in DDW-100 is as CO.
Note! Before connection and installation one of the connected unit have to be
reconfigured as CPE
Depending on the quality of the line and the distance there is possibility to select the
optimised speed.
This is done via DIP switches in the unit configured as CO. Factory default is 192 kbit/s.
When selecting higher speed note if the DSL link is established, if not, the selected speed
is to high fore the distance.

Cooling
This unit uses convection cooling.To avoid obstructing the air-
flow around the unit, use the following spacing rules. Minimum
spacing 25 mm (1.0 inch) above /below and 10 mm (0.4 inches)
left /right the unit. Spacing is recommended for the use of unit
in full operating temperature range and service life.
Removal
Press down the black support at the top of the unit. See figure.
Mounting
This unit should be mounted on 35 mm DIN-rail, which is
horizontally mounted inside an apparatus cabinet, or similar.
Snap on mounting, see figure.

NOTE
Railway installation close to the rails.
For a cable located inside 3 m boundary and connected to this port, the use of shielded
cable is recommended, this is to minimise the risk of interference.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 con-
nected to the protective earth.

DIP-switch settings
Before DIP-switch settings:
Prevent damage to internal electronics from electrostatic discharges (ESD)
by discharging your body to a grounding point (e.g. use of wrist strap).
NOTE DIP-switch alterations are only effective after a power on.
A setting configured by any other method during normal operation, overrides
the DIP-switch setting. However, at power up, the DIP-switch settings have
precedence over the setting configured by any other method.
