4.5. Replacement of Product
Disconnect all cables and unscrew the product from the wall. MTTR (Mean Time To
Repair), i.e. time for replacement of product is < 10 minutes.
4.6. EN 45545-2 Mounting Notes
Two product can be mounted together and as a single interior non-listed group in the
sense of EN 45545-2 definitions. For multiple product, the spacing requirements for
interior non-listed groups must be met.
4.7. Getting Started
The DDW-002-B1 is easy to use and install. The units work in a pair over existing copper
cabling infrastructure and automatically connect to each other when the remote device is
sensed over the interconnecting lines.
The installation procedure to get the application up and running is simple.
1. Connect the cable (twisted pair or parallell cable) to X2 pin 1 and 3 (polarity
independent).
2. Connect Ethernet to the X1 port on the front of the DDW-002-B1.
3. Connect power to the devices.
The following settings are valid for the Ethernet interface:
• Ethernet auto-negotiation enabled
• Auto MDI/MDI-X
• Auto-polarity enabled
The DDW-002-B1 will automatically detect the possible data rate to the remote device
(over the X2 - PLC interface ).
The link performance can easily be measured after the powerline link is established.
Different types of methods and tools can be used.
One example of recommended software for throughput testing is Iperf. Please refer to
Iperf user documentation for instructions of usage.
NOTE
If the PLC link is not established or the established data rate is not
suffcient for the application, the distance might be too long between the
devices.
The device is an unmanaged unit. If data throughput performance needs to be adjusted or if
no powerline connection is established, check cabling between the devices.
