What do you think? I have drawn a ev157 circuit showing this idea, check http: I think it maybe easier if you ask the seller directly.

I think your car remotes maybe not compatible with alarms, so it can not be controlled. This means that I will need a switches for each of datasheef setting to connect to EV What are these combination keys?

Identify RF Remote Control

Datasheet of EV usually only covers the encoder part, not the RF transmit circuit, maybe you can buy a Daasheet transmitter module to test first. April 16, at I heard there is one remote from Italy called evo works with both, you can try find on eBay, thanks.

It seems hard to get…?!

Not sure where to get a code reading device that displays the code anyway, but you might. I have some false alarms. RF Encoder, contains unique random address, 4 bit data, 12V operation, Eqv.

Available We dispatch same day if ordered by 4PM excluding holidaysthen courier usually takes days. Reduced size and weight High reliability and ruggedness No tuning or readjustment required Mass production capable. April 15, at Learning code remote control using EV chip is also known as self-learning copy remote, which can copy fixed code or learning code remote controls face to face.

Hi William, thanks for your fast answer. This information is used in remote control applications. Identify Oscillation Resistance The darasheet resistor value determines the transmitting OSC frequency, a higher oscillator resistor value will result in a lower OSC frequency, thus a longer wavelength, which will make the receiver pickup the signal easier.

Combination keys are what we usually called in factory, actually it is combination of IOs. Code reader would increase the system complexity and overall cost, which I think not worth it.

July 28, at EV chip is a learning code IC which is widely used in self-learning copy remote or universal RF darasheet control duplicator.


Thank you for your help. July 28, at 1: Listens to modulated infrared signals Khz and removes its carrier frequency to output data. Fixed frequency model usually uses SAW Surface Acoustic Wave resonators to stabilize transmitting frequency, and is easier for operating frequency identification, while adjustable frequency model uses LC circuit, center frequency change is done using adjustable capacitor or adjustable inductor, and the operating frequency can be detected by spectrum or oscilloscope.

The typical inner photo of RF remote control is listed as follows. April 15, at 9: November 9, at daasheet Rolling code remote control is usually duplicated using remote control duplicator, the number of rolling code remote control which can be duplicated is also limited. So it should be enough for your project, even using low combination system like The receiver board usually stores the transmitter ID in its memory before so receiver only responds to known transmitter IDs for secure datasbeet.
