Chapter 2 Connecting Mechanism
2.1 Introduction
The Powerline Adapter supports up to 200Mbps data rate. With this high speed connection rate, this Powerline Adapter allows you to set up a high speed home network by using your home existing electrical wiring. Simply plug this Powerline Adapter into an ordinary power outlet to extend your Cable/xDSL broadband connection or existing LAN network to any other electrical outlet in any room of your house.
Take notes that this Powerline Adapter works in pairs. You need to plug one Powerline Adapter into a power outlet for each computer and connect the Powerline Adapter to the computer’s LAN card with Ethernet cable; you will also need another Powerline Adapter connected to your Cable/xDSL broadband so as to extend your broadband connection or Internet surfing. With clean power line, the distance between two Powerline Adapters can reach 300 meters at lease, but the actual distance may vary due to the environment.
Section below describes the connection instructions and hardware connection mechanism.
2.2 Connection Instructions
To ensure the optimum performance of the Powerline Adapter and significantly improve the transmission capacity of the network, we recommend that you comply with the following connection rules:
yPlug the Powerline Adapter directly into a wall socket but not the multiple sockets.
yTo take full advantage of the filter function of the Powerline Adapter and to improve data transmission in the network, always plug the multiple sockets into the integrated electrical socket of the Powerline Adapter.
