The Computer Interface Module, model UMC, is used to exchange digital commands between a PC (personal computer) or home automation controller and UPB (Universal Powerline Bus) devices in the home. The module communicates these commands over the AC power wiring.
Model UMC-DB9 provides a Serial RS-232 interface with a DB9 connector and cable, for both configuration and control of UPB lighting.
Model UMC-USB provides a USB interface with a USB cable, for configuration of UPB lighting only. The UMC-USB is not recommended for home automation controller interface applications (e.g. alarm system, PC or whole home controller).
UPB devices can be freely located anywhere in the home. No additional wiring is required and no radio frequency signals are used.
Note: When using a UPB enabled alarm system or home automation controller for systems other than lighting, it is recommended to use the RS-232 interface, as RS-232 is a more robust communication protocol.
