What is Wiegand?
Wiegand is the most common method of communication used by access control devices.
The Door Interface Board (DIB) in the ICU allows for both wiegand input and output. A card reader (such as prox card) can pass the user ID # to the IrisAcccess system for verification and the DIB can also output the user ID # to access panels that emulate a card reader.
Proximity and magnetic stripe readers use as number of wiegand entry access (EAC) control formats to communicate with various (EAC) vendor door controllers.
Wiegand timing, number of bits, facility code length and wiegand format can vary greatly from access panel and reader manufacturers.
