Essential Info

Simply Automated's UTR 3-Phase Repeater was designed to improve communication in a UPB home lighting system comprised of Transceiver Switches/Dimmers, Receiver Plug-In Modules, and more. This device not only repeats the UPB messages it also bridges your electrical phases allowing the UPB signal to travel along all three separate 120V legs of powerline. The UTR receives the UPB messages sent from a device on one electrical phase and repeats that message over all three electrical phases. This 3-Phase repeater also features a RS-232 serial port. This is used to receive and transmit UPB signals from a host computer or home automation controller. 4 LED indicators are housed in the device to offer a visual display for repeating over each phase and operation of the UTR.

More Info

The UTR phase coupler wires directly to the homes main service panel. Once installed UPB UpStart configuration software will enable this device to be used as a (CIM) Computer Interface Module. This software must also be used to configure the UTR for sending repeater messages. This software is available on the Simply Automated website. 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.
