Linear DNR00100 1-Channel MegaCode Plug-In Receiver (MDR/U)

The Linear 1-channel plug-in receiver (MDR/U, model DNR00100) provides a quick way to add MegaCode remote capability to almost any garage door operator. MegaCode operates at 318 MHz and supplies more than one million radio codes to virtually eliminate code conflicts. Programming is handled through a convenient learn mode that accepts up to 10 MegaCode transmitters. Unlike the older installation that required Linear's MDR receiver plus a separate power transformer, the MDR/U plugs directly into a standard electrical outlet and only needs a single two-conductor wire run to the operator's push-button input. The unit offers one normally open contact output that pulses for 0.5 seconds when activated. Features: universal MegaCode compatibility; compact plug-in housing for easy installation; single two-conductor connection to the operator; learn-mode setup with 10-transmitter capacity; normally open contact output (0.5 second pulse). Specs: Power: 110 VAC +/- 10 percent 60 Hz. RF frequency: 318 MHz. Dimensions: 2.52" W x 2.5" H x 1.61" D.
