6.3.2 Connecting readers with Wiegand interface
The electrical properties of Wiegand standard interface provide a guaranteed reader connectivity
range up to 60 m, which is sufficient in most cases. When using appropriate cables and laying
conditions, the connection range can be increased up to 150 meters (see Sec. 16 Appendix 4.
Summary for cable selection).
