Operation mode


The reader transmits 125 KHz low-frequency signal uninterruptedly (or triggered by switching signals of infrared or ultrasonic sensors) to form a low-frequency cover zone. Any semi-active electronic tag entering the cover zone will receive low-frequency ID code. And the RSSI value of low-frequency signal strength, tag battery voltage status, tag anti-dismantle status and other information will be analyzed. All information is replied to the reader immediately with 2.4 GHz signal. It can also receive the signal from the active tag in real time and transfer the received data to the backstage management system. In special applications, data can also be written to tags or parameters of it can be changed.


Recognition range


In a good visual environment, the maximum identification distance of 2.4 GHz RF terminal can reach up to150 meters. It can extend a built-in 125 KHz low frequency antenna, and the transmitting distance can reach up to 5 meters.


If necessary, the low-frequency antenna with 1-3 channels of 125 KHz can be extended to multiply the low-frequency transmission distance. Multiple readers can be combined into identification zone for access control or channel control.

Recognition speed & capability:

When the active tag runs at a speed of up to 200 km/h within the effective range of the reader, stable recognition are ensured.

The reader can read more than 500 active or semi-active tags at the same time. In a quite short time, it can ensure all recognition with no omission. 


Communication security

When the reader and the active tag communicate, special communication protocol is used to verify the legitimacy of the device. The meticulous encryption algorithm is developed to ensure data security in the communication process.


Reliability

The product fully considers the application requirements of industrial environment such as lightning protection, waterproofing and shock protection.

  


Interface standard

The reader provides standard hardware interfaces such as RS485, weigand26/34 or RJ45. Other interfaces such as RS232, TTL or extended WiFi can be provided on demand. The company provides standard software interface that conforms to windows operating system platforms. Underlying communication protocols are provided.
