Control your lights and appliances without getting up from your computer! The Computer UPB Interface Module is a plug-in module that enables computer-based configuration and control of household lighting, appliances and other devices over the powerline using the highly reliable Universal Powerline Bus (UPB) technology. By plugging in the Computer UPB Interface Module and connecting it to your PC via the included DB-9 cable, you'll be capable of communicating with UPB plug-in modules and/or other UPB devices (sold separately) to control virtually anything that can be connected to existing wiring anywhere in the home, all via your PC. With the free, downloadable UpStart software, the computer can then be used to configure and/or control UPB devices. UPB technology delivers exceptional reliability and noise immunity at a much lower installed cost when compared to hardwired and RF solutions, and you'll experience no interference from adjacent homes. UPB technology is not X10 compatible. The Computer UPB Interface Module receives and transmits UPB digital commands and converts these signals to a serial RS-232C interface format. A pass-through (non-controlled) power outlet is provided on the face of the module, so you won't lose any outlets by installing this module. The Computer UPB Interface Module is USB compatible when used with an RS-232-to-USB adapter (sold separately).
