Extend the power and scope of your home control system using the most reliable, economic and easy to install dedicated transmission line available! This 8-port expansion hub uses the RS-485 protocol, which is not only more powerful than the RS-232 protocol, but is also easier and more affordable to install. Because RS-485 signals travel farther along the line, you can run dedicated cable without having to purchase expensive repeaters, couplers, amplifiers. You'll also save big bucks by reducing the amount of wiring used, since devices connected to the RS-485 line can be daisy chained, instead of home run. 32 of these hubs can be connected to the Stargate controller.
