d) Wiegand interface
There are two application options for the Wiegand interface of the access system:
1) The access system is used as an external card reader
The access system can be connected to a compatible
Wiegand controller and used as an external card reader.
The Wiegand controller must support a 26-bit protocol
that is used for the transmission of transponder data.
Follow the operating instructions for your
Wiegand controller.
1 Access system
2 Wiegand controller
3 Power adapter
The access system has the operating voltage of 12 - 18 V/DC. If the Wiegand controller does not support
this operating voltage, the access system will require a separate power supply unit. The wiring diagram will
then be different from the one shown in the figure.
2) An external card reader is connected to the access system
The access system functions as a Wiegand controller and can be operated with an external card reader (with 26- or
34-bit protocol, automatic recognition).
Both card readers for 125 kHz transponders and card readers with MIFARE
®
smart card technology
(13.561 MHz) are supported.
When a MIFARE
®
smart card reader is used, new transponders can only be paired via this card reader.
However, when a card reader for 125 kHz transponders is used, transponders can be paired both via the
access system and the card reader (should you face any problems, use only the external card reader for
pairing).
Make sure the two data cables D0 and D1 are not swapped; D0 must always be connected to D0 and D1 must always
be connected to D1. Other connections can be carried out as shown in section 7. b). Always follow the operating
instructions for the external card reader.
