How Cloning Remote Control Works

Here at Solidremote, we provide cloning remote control or remote control duplicator that works with many fixed code original remotes, such as Came Top432na etc. the basic instruction is very simple, just put original and our duplicator together and click a few buttons, you will get a exact duplicate of original remote that just works same as original.

Have you ever wondered why the new remotes just works, you will ask the same question if you want to dig deeper and have a bit more interest, so here below we will have a short introduction to how cloner remotes works.


Above photo is taken on Aug 3rd 2013 showing the inner circuit of our SR-C1 Came Top432na cloning remote control, we will take this model as an example to show how cloning remote works.

As you can easily imagine, the most difference between cloner remote and ordinary remote must be the former can recognize the signal transmitted by other remote, then record the signal as recorder, after that, it can transmit the exact same signal to open the door.

After you received your new cloner remote, the first step would be clear code, which just simply clears all codes stored in memory in factory for testing purposes, and of course you won’t need these codes since you will copy your own remote controls.

After sucessfully cleared the codes, your remote control has automatically entered cloning mode, pressing any button would be ready to receive the signal from existing remote, so here comes the receiver part – that can read the signal transmitted by other remotes, the receiver part is a very simple LC OOK data pickup circuit which transforms radio waves into digital data like 0101.. – since the cloner are called face-to-face, which means the receiver range is pretty much 1cm or less, so the receiver’s sensitivity can be not as high as what we used on actual receiver – that normally works in range of 100m+

The LC receiver circuit is called diode detector, which can demodulate waves carried by amplitude modulation and OOK of course, the circuit is composed of one diode and several capacitors and resistors, this receiver type can be normally found in our radio, especially those simple ones used in school labs.

And the transformed high and low voltage data is connected to certain pin of chip, then piped into the chip and processed there, if the signal transmitted can be recognized by chip as valid signal, by valid it means there is a same segment in signal that repeats a lot of times, which is also known as the minimum working unit, then it will store the code in EEPROM, which is a storage unit will keeps the data for years if wanted.

Then after sucessfully cloned, the transmitter will transmit the exact same signal when next button press, other parts are just the same as normal transmitters you can find out there.

Simple enough huh, the cloner remote can be considered just the same as recorder, the only difference is ours record RF signal, while your recorder records sound waves.
