Overview

  • Makes any garage door operator compatible with MegaCode transmitters
  • Get higher security RF capabilities without replacing your old garage door
  • Easy to install - one connection using two-conductor wire
  • Learn mode with 10-transmitter capacity

Essential Info

Often people think that retrofitting their old garage door involves a lot of hassle, since most retrofit kits have a box that contains the circuitry, plus the AC adapter "brick" needs to be mounted somewhere near the opener. Linear Corporation has created a one-channel universal receiver that has everything contained in the AC adapter, so you can just plug the unit into the same outlet as the opener. Then you simply run a single two-conductor wire from the MDR/U to your push-button input.

What's Included

  • 1x - MDR/U 1-channel 110V receiver - MDR/U
  • 1x - Retaining Screw
  • More Info


    This receiver makes any garage door operator compatible with MegaCode transmitters, which features over one million radio codes to all but eliminate any possibility of code duplication. With this updated system, you'll also be able to use the newer gadgetry that your old opener couldn't allow, such as keypads and keyfob transmitters. Two-conductor wire is required but sold separately.

    The Megacode receiver did not work for me so I returned it. Order cost was about $31.00 and I am only getting back $25.00. The difference must be a re-stocking fee which doesn't seem right. Not happy.
    MARK -- brighton, MI   2/3/2014
    Worked ok, but not impressed with the range. Have to be just outside garage door to get it to work.
    DAVID -- minster, OH   9/29/2013
    Fast shipping,good price and works great. Thanks Dave

    This product allowed me to consolidate my gate opener and garage door opener into one device.
    BARRY -- monroeville, PA   10/17/2011
    I recently bought a house that had 2 very old but functioning garage door openers. The remotes were long gone and because of their age, none of the generic remotes were compatible. I was just about to replace both openers at great expense when I stumbled on to this product. I figured it was worth a try. Installation took 5 minutes and the openers work like new. It solved the problem, works perfectly and saved me money. I'm very satisfied.
    HARRISON -- colorado springs, CO   10/13/2011
    Works like a charm with my 1980s garage door opener, though some times I have to engage several times to get it to engage the opener. There is a difference in the closed relay and the push button engaging the opener.
    ALAN -- brookfield, WI   8/18/2011
    Exactly as advertised. Terrific addition to my garage.
    PETER -- cortland, NY   10/29/2010
    Receiver plugs in and works well with the new Xmitters. Don't have to replace the 30 yr old garage opener. I'm happy.
    ELMAR -- malibu, CA   9/30/2010
    Simple and Perfect Solution!
    BRENDA -- las vegas, NV   9/28/2009
    Did not work for our Legacy garage door opener.
    THOMAS -- ridgewood, NJ   12/6/2008
    Does what it says, easy to install.
    WILLIAM -- st louis, MO   8/16/2008
    Now both garage door's have a Megacode Receiver. Both work very well.
    PETER -- mclean, VA   1/3/2008
    instructions did not exactly match the receiver
    JAMES -- binghamton, NY   12/7/2007
    Quick, easy installation and the unit performs as advertised. Great way to keep your old garage door opener working rather than replacing the entire unit because the receiver is failing. It also provides upgraded security if you have an old receiver that is programmed with dip switches.
    JOSEPH G. -- seattle, WA   10/17/2007
    Installation is a snap, works as advertised!
    JOSEPH -- defiance, OH   7/5/2007
    Works very well, using it with the 7444K Wireless Keypad, very easy to set up.
    MACIEJ -- runnemede, NJ   5/4/2007
    Took more time to open the package than it took to install. Excellent product!!!
    PHYLLIS B. -- longmeadow, MA   4/11/2007
    I am very thrilled with both the transmitter and receiver. It saves me from having to purchase a new garage door opener. Thank you for your great product and excellent service. I would not hesitate to order from you again and would recommend you highlyto my friends.
    ERIC -- los altos, CA   3/7/2007
