What is Wiegand input and output?

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. Wiegand timing, number of bits, facility code length and wiegand format can vary greatly from access panel and reader manufacturers.

What is Wiegand output?

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. Typically, Wiegand technology is found in cards, fingerprint readers, or any other data-capturing devices.

How do you test Wiegand output?

Procedure

1. Check the pulse interval and width of the 3rd party controller.
2. Set up the pulse width and pulse interval accordingly.
3. Since the suprema device is sending the signal out to the controller, the Wiegand signal should be set to *Out*.
4. Check that you have selected the correct Wiegand format and click apply.

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.

What is Wiegand 26 bit?

The “26-bit” referred to the protocol of the data on the card. The data encoded using 26-bit format consists of 255 possible facility codes and within each there is a total of 65,535 unique card numbers. This is a relatively small number of unique cards, so additional authentication is often used.

What is Wiegand communication?

Wiegand refers to the technology used in card readers and sensors. Wiegand technology is a wired communication interface that operates between a reader and a controller. Typically, Wiegand technology is found in cards, fingerprint readers, or any other data-capturing devices.

Is Wiegand secure?

Wiegand swipe cards cannot be erased by magnetic fields and are more durable than other key cards because they do not contain microchips. This made them reliable, easy choices for equipping systems with swipe cards.

What is H10301 Format?

The standard 26 bit Wiegand format is H10301. The format consists of 2 parity bits, 8 bit Facility Code and 16 bit Cardholder ID fields.

Why are twisted pair cables unsuitable for wiring Wiegand readers?

Twisted cat5e and cat6 are not good to be used for wiegand readers. The twist by the data can cause problems with the data packets. If you have to use cat5e or cat6, make sure to have the data running on two different twists. Usually the longer the run, the bigger chance of there being reader issues.

What is Osdp reader?

Open Supervised Device Protocol (OSDP) and Wiegand are technologies used to link access control systems together. While Wiegand readers are one-way communication devices, OSDP readers offer two-way communication. In other words, OSDP readers can send and receive communication from the controller.

How far is Wiegand?

500 feet
The theoretical limit for Wiegand signal wire to a reader from the panel is 500 feet assuming you are using an 18 AWG shielded, excellent quality cable in a noise-free environment. If you use 22 AWG, that distance drops dramatically to 250 feet.

What is a Wiegand interface module?

The Dual Wiegand Interface is a module which allows Wiegand technology readers to be connected to a ChallengerPlus or Network Access Controller system. This module also provides inputs and outputs which may be used for door functions such as, connecting door sensors, warning devices and controlling locks.
