MDR-U Linear Mega Code Universal Plug-in Receiver

The Linear MDR/U 1-Channel Plug-in Receiver is a versatile (universal) receiver that makes it very easy to equip nearly any garage door operator for use with Linear’s popular Mega Code format transmitters. Mega Code uses a frequency of 318 MHz and features over one million radio codes to all but eliminate any possibility of code duplication. It offers simplified programming via the receiver’s learn mode. It can be used to send a remote-control signal from up to 10 Mega Code transmitters. A learn mode dramatically simplifies programming to just a button press.
