2. No warning is received when placing a finger on the biometric sensor
It the optical barrier has stopped working, an
event will have
been generated at some moment to indicate the error status. The most frequent causes
of this fault are:
- The finger is left on the biometric sensor for too long.
events are
generated until a Watchdog appears and equipment switches to error status. It
returns to normal when the finger has been removed.
- There is too much ambient light on the biometric sensor. This light stops the opti-
cal barrier from working correctly and probably also stops the FingerVein sen-
sor from making a correct identification. We advise you to protect the
BioMax2
/ KBio2-Online
terminal against excessive light, especially sunlight.
- Dirt on the optical barrier. Clean both lenses of the optical barrier with a wet cloth.
Even if we cannot solve the problem, an alternative way exists: the green key (for
example) could be used to trigger fingerprint identification as well.
4. BioMax2 / KBio2-Online electronics does not recognise the proximity card
Ensure the following:
- The reader is correctly connected to the
BioMax2 / KBio2-Online
electronics,
either via the Clock&Data or the RS-232. See
chapter 4.1.: “Connector signals,
BioMax2” , chapter 4.4.: “Connector signals, KBio2-Online” .
- In the case of UART0, make sure that no two readers are simultaneously connec-
ted to the same port, one through J14 connector and the other through terminal
block J3.
- In the case of UART1, make sure that no two readers are simultaneously connec-
ted to the same port, one through J7 connector and the other through terminal
block J1.
- In the case of UART0 / UART1, check that their configuration parameters are cor-
). In particular, ensure that the UART and reader
transmission speeds coincide.
- In any event (RS-232 or Clock&Data), check that the reader configuration param-
eters have the ports required enabled (see
)
5. BioMax2 / KBio2-Online electronics does not generate events
To generate an event,
BioMax2 / KBio2-Online
electronics must know several things:
- Via which protocol to generate the event (Bio-OCX UART0, Bio-OCX IP, KSP-
IP): it is always generated depending on the last communication received from
