Connecting as a standalone
BioStation A2 can be connected to the door lock, door button, and door sensor directly without connecting a separate I/O device.
•
BioStation A2 can be used as a multi-door controller with the slave devices with the RS485 cable. The slave devices are used as dummy readers and
authentication is performed in the master device.
•
If Xpass is connected to the master device, only card authentication can be used.
•
The maximum number of slave devices available to connect varies according to the authentication method, number of users, and number of
devices. Also note that the number of slave devices affects the fingerprint authentication speed.
•
A master device can control 31 slave devices. The bandwidth of RS485 allows for up to 7 fingerprint authentication devices to be connected.
