Most of the access controllers on the market use Wiegand interface to connect with the card reader.
The nominal distance of Wiegand transmission is 100 meters, actually between 20-60 meters, so during system deployment, the distance between the access controller and the card reader is usually too long, which may cause This results in the access controller not receiving information from the card reader.
The Wiegand signal extender converts the Wiegand output of the device into a 485 signal, and the transmission distance of the Wiegand signal is greatly increased to a theoretical maximum of 1200 meters by twisted pair transmission.
The extender adopts anti-interference MCU processing chip, built-in monitoring circuit, and automatically detects the working status of the device.
When the operation is abnormal, it is automatically reset to ensure that the converter never crashes and can work 7 days × 24 hours.

Central control Honeywell, Hikvision, Da Shi Smart, Kesong, Pike, Jieshun and other well-known brand card readers, fingerprint reader devices, facial recognition devices, Bluetooth card reader devices and other equipment with Wiegand protocol.
This converter - extender automatically recognizes extended Wiegand formats.
The Wiegand protocol is a communication protocol created, patented and introduced to the market by the HID company. It is unidirectional and allows data transmission between a reader.
(card reader) and a controller (access control). The protocol establishes data, power and signaling lines.
The Wiegand interface is a wiring standard used to interconnect peripherals such as fingerprint readers or card readers and uses three wires:
The communication protocol used in a Wiegand interface is the Wiegand Protocol.
