Network Adapters connect diverse and previously unconnected devices and appliances in a network-based home, school or business. Using many commonly needed controls and sensor inputs in one box, the GC-100 provides an easy way for controlling real-world devices, reducing the time and complexity of an installation by eliminating piggybacked components and multiple power supplies. By simply sending commands over the network, your audio/visual equipment is turned to the proper volume by infrared (IR), shades are lowered with relays, and your favorite DVD is selected through serial communications; and all started with the push of a button. As a result of using open standards (for ex Ample, TCP/IP), any networked device, such as your PC, can send and retrieve GC-100 data. With the GC-100, a variety of devices can be connected to control and monitor the environment over a network or even the Internet.
