Working Principle of 74525305

74525305 uses an integrated GPRS/GSM/GPS module, which allows communication over the public mobile phone network. It sends data signals between the host device and the remote device. It also adopts a proprietary protocol to communicate with the host device and the remote device for data transmission and control.The basic operation of 74525305 is divided into three steps: the user authenticates the device, the host device performs the access authorization and control operation, and the remote device performs the corresponding action. In the first step, the user connects to the device via a transponder card or Bluetooth reader. Then the device will perform user authentication by comparing the data stored in the card with the data stored in the host device. In the second step, the host device will transmit all the information to the remote device to perform access authorization. The remote device will then check the data and reply with access control information. If the information is correct, the remote device will open the electric lock and grant access to the user. On the other hand, if the information is incorrect, the remote device will not authorize access and will reply to the host device accordingly. In the last step, the host device will provide feedback according to the return value from the remote device. Finally, the user can gain access to the premises or be informed that access is denied.

Conclusion

74525305 is an advanced access control device with powerful features, which can be applied in many fields such as office, residential areas, and industrial automation, etc. The working principle of 74525305 is based on the authentication, authorization, and feedback mechanism. With its application, it provides more convenience and security.
