The UMC series are plug-in modules designed to convert serial RS-232 or USB signals into highly-reliable, Universal Powerline Bus (UPB) signals. They provide a bridge between the PC/controller to the powerline via the module's plug-in AC connection. This enables computer-based configuration and control (use UMC-DB9 for control) of lighting scenes, switches, modules and other UPB devices, over the power line. UPB devices such as switches, multibutton controllers and schedulers are easily integrated in to a new home or can replace switches and timers in an existing home. UPB technology requires no new or special wiring, it provides a flexible, low-costs alternative to hardwired or RF home lighting and automation strategies. The UMC-DB9-W is ideal for controller applications since it uses the highly reliable RS-232C serial interface; common to most desktop PCs, home automation controllers and alarm panels. The UMCDB9 can also be used to configure any UPB devices.
