3.2.8 Wiegand Output Connection
The equipment provides standard Wiegand26 output, which can
be connected to most of the current access controller, in the same
way as connecting an IC reader or a password keyboard.
Generally, it is preferable to limit the length of any connection line
to an access controller within 90 meters. (A Wiegan signal
extender can be used for a longer transmission distance or a
place with strong interference.)
Note

）
The distance between device and access controller or card reader
shouldn’t be over 90 meters (If a longer distance is needed or there is
interference in using environment, please use Wiegand signal de lay.).
2) To ensure the stability of the Wiegand signal, the device must share the
GND with controller or Wiegand reader.
3) If the distance of Wiegand output or 485 communication is over 90 meters,
in order to reduce the interference caused by the long distance, it is
suggested to use the cable with shield and connect the shield cable to the
SGND terminal.
