Open Box Unit. Not Used.
THE CR234 is a coupler-repeater designed to receive A10 or X10 Powerline Control Component signals from one phase of a 120/240 VAC split-single phase power distribution system and retransmit them onto both phases (as low as 25 millivolts peak to peak) or SCC (Signal Coupling Conductor) lines (as low as 50 millivolts peak to peak). In doing so, it effectively amplifies the signal. The CR234 is also capable of receiving and retransmitting Dim and Bright signals nearly simultaneously. In addition to SCC connections the CR234 also has special signal processing functions to better operate in complex coupling situations (described in detail in the "Installation" section). Its signal output will be greater than 5 volts peak to peak @ 5 ohms. Actual output is dependent on facility impedance and use of SCC output. This unit is not intended for 120/208V, 120/208/240V High-Leg Delta, or 277/480V systems.
