Synchronization of anti-theft systems

Synchronous data transmission is a method of transferring digital data over a serial interface, in which the receiver and transmitter know the time of data transmission, that is, the transmitter and receiver work synchronously, in time. Synchronization of the receiver and transmitter is achieved either by entering a synchronizing sequence (for example, at the beginning of the data transfer, a deterministic signal is transmitted with a known switching state from "zero" to "one", the timing of the arrival is synchronized between the receiver and transmitter, by setting the Gating pulses to the center of the bit interval), or by applying a method of encoding with self-synchronization when transferring each bit of data

For the correct operation of the anti-Theft system, synchronization is extremely important. Anti-theft antennas work on the principle of "radar" sending a signal at a certain frequency trying to determine the interference (anti-theft sensor) in the controlled area.
If there are several such nearby antennas-"radars", then the signal sent from one antenna may coincide with the process of "listening" to the control zone of another antenna. And this signal will be perceived by the antenna as a hindrance or as an anti-theft sensor.
In order to prevent this from happening and requires a structured sequence of the signal.
This sequence, in our case – is called synchronization.
Synchronization can be wired when the priority command of the signal from the Main antenna to the other antennas in the line is sent over the wires.
Or, as in the case of RS-Mono antennas, synchronization is based on a software pulse algorithm that allows you to reduce the probability of coincidence of simultaneous supply of pulses of two antennas – to zero. Thus eliminating false positives antennas at each other.
