Essential Info

Looking for a way to access and manage common household devices via network-based software and an Ethernet network? This Home Network Adapter is exactly what you need! With two serial ports, three relays and six independent Infrared (IR) outputs, it can control IR, relay and serial devices, such as televisions, motorized blinds, security systems and more.

Unfortunately, most household devices such as TVs and stereos, and security systems can't communicate over networks. Top-to-bottom proprietary systems can control household devices, but are extremely expensive and require specialized dealer training for installation. Recently, more affordable home control and automation software, based on open systems and standards has become available. However, to use the new open systems software, multiple devices, and sometimes piggybacked equipment, is necessary to connect various types of household devices to a network. This method can be quite expensive, somewhat complex, and often unreliable. Global Caché’s cost effective and easy-to-use GC-100 is designed to solve those problems. Utilizing Global Caché’s GC-100 Network Adapter, the most commonly used devices can be easily managed and accessed via network-based software. Our unique modular mix-and-match design allows integrators, installers, and OEMs to control diverse systems such as entertainment, security, lighting, and irrigation in a cost effective manner.

This model includes:
  • Power input: 12 to 15V DC@500mA (wall power adapter included)
  • IR: 3.5mm mono jack, independent user selectable IR outputs or sensor inputs
  • Serial: Male DB9, RS232 up to 19.2Kbaud bi-directional hardware flow control
  • Relay: Screw terminal plug, 24V AC/DC@.5A N.O. contact with transient voltage suppression
  • LEDs: Link, network activity, power, IR, and sensor activity

    works great!

    In my rack controlling Set-top boxes, Amps and Ethernet Switch for my home distribution.
    JOHN S. -- half moon bay, CA   3/31/2011
    This device works flawlessly!
    DANIEL J -- temecula, CA   8/23/2010
    This worked as advertised. I'm happy with it. The only problem I had is that you can only send commands out one IR port at time. Same goes for flipping the relays. I put a 100ms delay between the events and that worked fine, but it was a pain to figure out and to have to add the extra code every time I want to do more than one thing at once. Besides that minor inconvenience, I wouldn't hesitate to buy another one of these.
    PIERRE -- sunnyvale, CA   5/7/2010
    Works as expected. Only complain I have is that the number of relay connectors provided with the product is less than the # of relay ports. Annoying.
    EVEN BREISJOEBE -- oslo, XX   4/10/2010
    The price was ok, but I understand now that you get what you pay for... Please be aware: You can not have more than one simultanious connection to this device! (i.e. one iPad). Another ting to mention is that the setup procedure is not very userfriendly either.. You have to use at least 4 differentprograms to even get started... And they are all VERY buggy. There was some kind of usermanual that came with the controller, but I found it not very helpful. I had to find answers online, by others who had experienced the same kind of trouble that I had. So because of all the limitations, and the lack of information given about this produckt, I'll only give one star. Basically I cant use it.
