What is a Wiegand card reader?
Wiegand refers to the technology used in card readers and sensors. This system is a wired communication interface that operates between a reader and a controller. In summary, Wiegand devices are cards and any kind of data reader that operates on a special wire communication system.
How do Wiegand cards work?
Wiegand, who in the 1970’s discovered that wires made of a cobalt, iron and vanadium alloy will switch polarity when run through strong magnetic fields. Placing a sensor coil nearby will be capable of picking up the change in polarity as a high-voltage pulse, and then translate that pulse into data.
Is Wiegand a RS485?
Wiegand is a standard interface used in contactless card readers. Wiegand to RS485 bidirectional interface converter. Thus, standard contactless card readers can be easily connected to a PC or similar system wia RS485 interface.
How do you wire Wiegand readers?
1. Wire the Access Controller to 12v DC power supply. 2. Route the interface cable from the reader to access controller device….Step by Step instruction.
