- If Auto-On could not be enabled, an
time we contact the FIM module through
- If two FIM modules are connected to BioMax2, both may activate the Auto-On
mechanism. In such case, the key value that is reported by the auxiliary FIM is
one count higher than the one of the main FIM (by default, values
$41
for the
main FIM and
$42
for the auxiliary FIM are used, corresponding to green and
red keys on the BioMax2 keypad).
5.4. Connection to an auxiliary board, Bio-OCX protocol
It is worth remarking that various electronic devices, based on protocol Bio-OCX, can be
easily connected to the RS-232 ports. That provides Ethernet connectivity to legacy
electronics such as the old
BioMax
and
KBio
, which may be converted to KSP nodes
when connected to UART0 of
BioMax2
or
KBio2-Online
.
We may also adapt to very particular installations, for instance by connecting a
Series-
16R board
for additional relays.
5.5. BiomaxPlus-DB module
Kimaldi Electronics offers the
BiomaxPlus-DB
module, which provides an offline
behaviour, so that it acts as a back-up host when the main one is out of reach.
The
BioMax2
+
BiomaxPlus-DB
assembly is commercially known as
BiomaxPlus
.
The
BioMaxPlus-DB
module is recommended for online access control applications,
where offline control must take over if communication to the main Host is lost. In
particular, if biometric identification is required, the template database must be located
in the FIM module as well.
When using the
BioMaxPlus-DB
module, the following parameters must be correctly
configured:
•
: UART2 is configured to link with
BioMaxPlus-DB
.
- Recommended value:
$D1
(19200 baud communication)
: It sets the maximum response time (in tenths of second), allowed for
Host response, upon event issued by
BioMax2
(key pressed, finger detected, etc.). If
the Host does not reply promptly, it is assumed to be lost, and operation mode
switches to Offline.
- Recommended value:
$0A
(1 second)
•
: It sets the maximum time between Host instructions (we assume
that the Host is regularly sending Keep-Alive frames to
BioMax2
). After such
period of time, the Host is assumed to be lost, and operation mode switches to
Offline.
- Recommended value:
$64
(10 seconds)
