3. Functionality
The EFIS321 scanner provides to get the fingerprint images using Ethernet interface. EFISC Scanner
control SDK lets have to simple interface to device.
The scanner supports two modes of work
-
active mode (scanner works as TCP client)
-
passive mode (scanner works as TCP server)
In active mode the scanner waits the finger on the sensor. When the finger is detected, scanner will try to
establish the connection with TCP server. The EFIS321 has TCP server address in current configuration
of device in flash memory. TCP server provides the connection and takes the fingerprint image for
processing.
In passive mode the scanner works as TCP server and waits a connection from TCP client. If TCP client
has the connection from EFIS321 the client application can get the fingerprint image and control other
feature of device by SDK.
If your network has DHCP server you can switch on DHCP service in EFIS321.
Note: Better to use the DHCP service in active mode.
