    (web browser, second WebRelay-Quad , etc.). Final installation note. This ControlByWeb product supports connection to 10Mbps and 100Mbps networks. Although 100Mbps networks are faster, the amount of data transferred to and from this device is very minimal and little if any performance increase will be gained by setting it to 100Mbps.

    Revision 2.2b WebRelay-Quad Users Manual 1.4.1 Basic Setup The illustration below shows a simple WebRelay-Quad application. The example shows how a 3-color industrial light tower can be controlled remotely over an Ethernet network. The three lights are connected to three of the relays so each light can be controlled individually. The lights can be connected directly to the relay contacts because they are low power lights (LEDs).

    Revision 2.2b WebRelay-Quad Users Manual 1.4.2 Controlling High Power Devices WebRelay-Quad can be used to control high power devices by using an external relay. In this configuration, WebRelay-Quad does not control the load directly, but controls the external relay and the external relay controls the load.

    Without a Computer WebRelay-Quad can be used in conjunction with other ControlByWeb products such as WebRelay the Five- Input Module. This allows users to control devices at a remote location by using switches or buttons instead of using a computer. The illustration below shows how three switches can remotely control three indicator lights in a light tower at a remote location.

This avoids having multiple WebRelay-Quad units installed on the network with the same factory default IP address at the same time. It may be necessary to clear the arp cache each time you swap WebRelay-Quad units on the network (this is because each unit has the same default IP address but different mac address).
