☑ The "Network Connections" window opens.
4. Double click on the LAN connection used to connect the Power Reducer Box to the computer.
• If Windows displays several LAN connections, there are probably several network
connections installed on the computer. Ensure that you select the correct network connection
that the computer is using to connect to the Power Reducer Box. If necessary, refer to the
manual of your computer.
• If no LAN connection is displayed, read Section 12.3 "General Troubleshooting", page 63.

5. In the "General" tab, select [Properties].
☑ The "Local Area Connection Properties" window opens.

☑ The "Internet Protocol Version 4 (TCP/IPv4) Properties" window opens.

Properties" window. With this, you can reset the computer to the previous network settings after
configuring the Power Reducer Box.
8. Adjust the following static network settings for the computer:
• Select the "Use the following IP address:" field.
• In the "IP address:" field, enter an IP address that is in the same subnet as the IP address for
the Power Reducer Box, e.g. "192.168.0.190". The Power Reducer Box is factory-set to the
IP address "192.168.0.200".
• Enter the subnet mask "255.255.255.0" into the "Subnet mask:" field.
• Delete any entries in the "Default gateway", "Preferred DNS server" and
"Alternate DNS server" fields.
Changing network settings
Do not change any of the network setting values if you are not sure of the consequences of the
changes. It is possible to adjust the settings in such a way that your existing network no longer
works at all or only partially. In the worst case, the computer will no longer be able to
communicate with the Power Reducer Box. In order to be able to make changes to the network
settings, you will require the necessary user rights on the computer. If in doubt, contact your
network administrator.
