Connections
The number of connections available varies between controller models but all controllers have the same basic confi guration. Each
controller can support at least one reader per door. Each door can also support push to exit, door sensor, lock output or an additional
reader for two way systems.
When connecting Dahua readers to Dahua controllers, Wiegand connections are not required if RS485 is used.
