Connecting to Secure I/O 2
Secure I/O 2 is an I/O device, can be connected to BioEntry W2 with the RS-485 cable. Security can be maintained even if the connection
between BioEntry W2 and Secure I/O 2 has been lost or the power supply to BioEntry W2 has been shut off due to external factors.
•
Use an AWG24 twisted pair with a maximum length of 1.2 km for the RS-485 cable.
•
If connecting with a RS-485 daisy chain, connect the termination resistor (120 Ω) to both ends of the daisy chain connection. If
connected to the middle line, the signal level becomes smaller and the communication performance will deteriorate. Make sure to
connect it to both ends of the daisy chain connection.
•
BioEntry W2 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.
