MCT-201 is a Miniature Pendant PowerCode Wireless Transmitter by Visonic. It is designed for emergency and control applications in wireless security systems, and home automation and remote control systems.

Characteristics

Transmitter ID: 24-bit digital word, PWMPulse Width Modulation w/with possible 1 lead bit and 1/2 FECForward Error Correction convolution. Each frame transmits 37 bits. Transmission Duration is limited by timer to 5 seconds from holding the button down.

MCT-201 Analysis

Spectrum of MCT-201 PWMPulse Width Modulation signal. Here you can see each of the pulse trains. These transmissions transmit as long as the button is pressed. Here you can see one pulse train's frames. There are a total of 8 frames. Each frame is identical, since this transmitter simply transmits the same 24-bit ID over and over again. Here you can see the width of each pulse train is 392 msmilliseconds (.001 of a second). Here you can see the width of the gap between pulse trains. It is measured to be 231 msmilliseconds (.001 of a second). Here is a single pulse frame, which a pulse train has 8 of. The width of a pulse frame is 45.25 msmilliseconds (.001 of a second). The gap between pulse frames is measured to be 4 msmilliseconds (.001 of a second). This is the waveform of a MCT-201 frame. Here you can see the PWMPulse Width Modulation waveform. The width of the short pulse is 400 us. The width of the long pulse is 800 us.
