| The MDRU is a versatile (universal) receiver that makes it very easy to equip nearly any garage door opener for use wit Linear's popular MegaCode format transmitters. |
| MegaCode uses a frequency of 318 MHz and features over one million radio codes to all but eliminate any possiblilty of code duplication. It offers simplified programming via the receiver's learn mode. |
| The MDRU replaces the MDR and plugs directly into any electrical outlet. All that is required is running a single two-conductor wire from the MDRU to the opener's push button input. |
| The MDRU has one normally open contact output. It can be used to send a remote control signal from up to 10 MegaCode transmitters. A learn mode dramatically simplifies programming to just a button press. |
| Makes any garage door operator compatible with MegaCode transmitters. |
| Simple Plug-in design. |
| Easy to install - one connection using two-conductor wire. |
