Self-Installable Interface for UPB-Controlled Devices Model UMC is a plug-in module that enables computer-based configuration and control of household lighting, appliances and other devices over the powerline. The module communicates using the highly-reliable Universal Powerline Bus (UPB) technology. UPB devices such as Model UMC are easily integrated to provide a flexible, low-cost alternative to hardwired or RF home automation strategies.

Model UMC receives and transmits UPB digital commands and converts these signals to a serial RS-232C interface format. With appropriate software, the computer can then be used to configure and/or control UPB devices in the home. A pass-through (non-contolled) power outlet is provided on the face of the module. The UMC-DB9-W is USB compatible when used with an RS-232-to-USB cable.
