Wiegand Port
Wiegand Port Wiegand Port
Wiegand Port Data Zero and Data One outputs
Configuration type 5Y (See App A of AC-01 Wiegand Specification)
Outputs Optically isolated open-collector outputs
capable of sinking 25mA
These outputs will need to be pulled up to 5V at
the inputs of the terminating Wiegand panel.
Optimum pull-up resistor values lie in the range
470Ω to 1kΩ.
Tpw (Output Pulse Width) 40 µs -255µs in 5µs increments
(with 470Ω pull-up resistor)
Tpi (Output Pulse Interval) 200µs to 20ms in 200µs steps
Hold-off time 50ms-20s in 50ms steps
