Wiegand do 485 Signal Extender, Kontrola dostępu Czytnik Wiegand do RS485

The Wiegand to RS485 Signal Extender uses high anti-interference MCU processing chip, built-in watchdog circuit, automatically detects the working state of the device, automatically resets when the operation is abnormal, to ensure that the converter will never crash. The circuit board is produced by full-patch process, the wiring is reasonable, neat and beautiful, and the circuit works stably and reliably. The special joint is used to ensure convenient and reliable wiring, and it can work stably for 7×24H for a long time.
This signal extender automatically recognizes most Wiegand signal formats, from Wiegand26 to Wiegand80. Different manufacturers of different brands of access control readers can be automatically identified, no need to set up to use. This product can be custom made.
Most of the access controllers sold in the market are connected to the card reader by the Wiegand interface. The nominal transmission distance of the Wiegand signal is 100 metrów, which is actually between 20 i 60 metrów. In practical applications, the distance between the access controller and the card reader is often too long, which may cause the controller to fail to receive the card reader information. W związku z tym, Seabreeze Smart Card Co.,Ltd developed the Wiegand signal extender. The principle is to convert the Wiegand signal of the access card reader into RS485 signal, transmit it through the twisted pair, and then switch back to the Wiegand signal, so that the transmission advantage of RS485 can be fully utilized to improve the Wiegand signal. Transmission distance solves the problem of Wiegand signal transmission over long distances. Field test, this Wiegand signal extender transmission distance of more than 500 metrów.

With the Seabreeze Smart Card Co.,Ltd's solution, in addition to solving the problem of reliable signal transmission, there are obvious cost advantages:
1. Wiegand signal extender is inexpensive.
2. Wiegand signal extender is easy to install and use.
3. Use low-cost super 5 network cable as the transmission line.
4. A standard network cable can transmit up to two sets of access control devices.
