The MDR is a MegaCode receiver which can activate the gate motors if the right code is received.
Product page: http://www.linearcorp.com/product_detail.php?productId=941
Manual: http://www.linearcorp.com/pdf/manuals/MDR_MDR-2_MDRM.pdf
Codes can be programmed in the receiver by pressing the "learn" button and activating the remote, which will transmit the signal.
The device requires a 24V power source, but it can go down to 17V.
@ -128,6 +131,9 @@ A LM78L05ACZ voltage regulator will provide 5V for the logic, except the relay.
The PICkit2 does not provide enough current to power the logic, but a USB port does.
The MDR-U is a more compact and semi-SMT version of the MDR.
Product page: http://www.linearcorp.com/product_detail.php?productId=942
Manual: http://www.linearcorp.com/pdf/manuals/MDRU.pdf
It plugs in a wall socket instead of requiring 24V.
Beware, the neutral blade is used as GND on the board.
Do not connect an oscilloscope earth to the PCB ground as you will short the mains.
