1. About this Manual
This manual applies to BioMax2 and KBio2-Online access and presence control
electronics, firmware versions 0x61.43 and 0x62.43 respectively.
2. Description
BioMax2/KBio2 electronics are designed as Online access and/or presence control
terminals..
• BioMax2 is versatile enough to control up to two Clock&Data readers and two RS-
232 devices, whether RFID readers or FIM modules for biometric identification.
It is also equipped with a 2x20-character alphanumeric display and a 4x4
numerical keypad.
• KBio2-Online is a more compact piece of hardware, only supporting one
Clock&Data reader and two RS232 devices (RFID readers or FIM modules).
User interface is simpler, solely based on LEDs.
• Default connectivity is based on both TCP/IP and UDP. Alternatively,
communication may be carried out via RS232. KiWi2 electronics can also be
connected for WiFi communications.
• It is possible to add the BiomaxPlus-DB device, intended for Semi-Offline access
control. That is, the system switches to Offline mode whenever communication
with main Host is lost. That way, it is BioMax2 itself managing and logging
access activity, until communication with main Host is recovered.
BioMax2 and KBio2-Online electronics are recommended for all access control
applications on electric locks, displays, leds, buzzers and ticker printers, etc. requiring
online operation. In particular, whenever biometrical identification is required, the
search engine may be installed in the main Host1or in the FIM module.
BioMax2 and KBio2-Online electronics may be controlled with serial commands or with
the help of the Active-X, Kimaldi Bio-OCX controller or its equivalent .NET version,
the latter method being recommended.
Except for their hardware differences, BioMax2 and KBio2-Online are equivalent in
terms of functionality and programming interface. With regards to BioMaxPlus, it
behaves as BioMax2 in all aspects, although it offers additional features.
1. Nitgen’s eNSearch and eNBSP libraries are available for that purpose.

5. Operation
Thanks to its IP connectivity, BioMax2 and KBio2-Online electronics make it possible to
install a network of biometric sensors or different types of card readers, accompanied by
the corresponding actuators or user interfaces. All the peripherals are Host-managed,
except for the biometric search engine, which may optionally be located in the FIM it-
self 1.
Normal operations consist of sending the events that occur to the Host. Normally, these
will be linked to a user ID. The user can simply put his or her finger on the biometric
sensor or start the identification by presenting the card or pressing any key. From hereon,
the Host will launch the identification and save its result. Once the identity of the person
is known, it will be possible to act on an access relay, display a personalised message on
screen or even ask for a code using the keycard.
An aspect that deserves special attention is the possibility to connect a choice of RS-232
peripheral devices to BioMax2, as indicated in chapter 7.
5.1. Connection of a FIM module
The most usual implementation of BioMax2 is BioMax2-FP, which features a FIM
module for biometric identification. The same statement applies to KBio2-Online. In
both cases, several types of use are allowed:
• Host-based template database:
- 1-to-N identification (1:N): the user places his or her finger on top of the
biometric sensor. An optical barrier activation event occurs, after which the
Host orders the capture of the user's fingerprint. The host will compare the
scanned template with all the fingerprints in its database (in the order of 25,000
users).
- 1-to-1 Identification (1:1): the user is identified using the card or by entering a
code. The Host receives the identification code and retrieves the corresponding
identification code from its database. This fingerprint is sent to the biometric
sensor, after which the sensor itself scans the user's finger to check its identify
with a 1 to 1 comparison (“Instant Matching”).
• FIM-based template database:
- 1-to-N identification (1:N): the user places his or her finger on top of the
biometric sensor. An optical barrier activation event occurs, after which the
Host orders the capture and immediate identification of the user's fingerprint.
- 1-to-1 Identification (1:1): the user is identified using the card or by entering a
code. The Host receives the identification code and triggers a comparison
between a template in the FIM module and the scanned fingerprint.
1. Offline behaviour is allowed when the search engine is located in the FIM. Typically, the
offline mode is enhanced by means of the BiomaxPlus-DB auxiliary board. See section 5.5

5.2. Connection to a configurable RS-232 reader
Kimaldi Electronics offers a series of readers (for example, KRD13M and SC42) that
have automatic operating modes and that also allow for two-way communications
between the Host and the reader (normally for configuration tasks).
BioMax2 and KBio2-Online are capable of capturing the events generated by these
readers and applying them with the same treatment as if they came from a Clock&Data
reader: automatic buzzer activation and LEDs and multiread filtering, etc.. These
readings are notified from the Card Reading event.
At the same time, two-way communications are permitted between the Host and the
reader from the combination of the Send to UART command and the Reception from
UART event.
5.3. Finger presence detection
BioMax2 and KBio2-Online electronics support two different means of finger presence
detection, depending on the installed hardware:
• LED optical barrier: This is the legacy method, the only one available for old FIM
versions (FIM20xx, FIM22xx y FIM30xx). The LED barrier is going to be
obsoleted. Please find more details in Subsection 5.3.1.
• Auto-On funcion: Newer FIM versions (FIM 5360 and later) provide an Auto-
Identify function based on an embedded capacitive sensor. This is going to be the
default detection method for BioMax2 and KBio2-Online. Please find more
details in Subsection 5.3.2.
5.3.1. Optical Barrier
BioMax2 and KBio2 terminals allow you to control an optical barrier to detect the
presence of a finger on the biometric sensor. In addition to the normal operating
conditions, the optical barrier manages two possible error situations:
1.- Permanent obstruction of the beam. In its idle state, the optical barrier detects the
beam of light from the LED emitter. If it does not detect the beam for some time, it
may be due to a mechanical or electronic fault. In normal conditions, 2 or 3 consec-
utive identification attempts can be made, without removing your finger from the
biometric sensor, before this error is triggered. This parameter can be configured, as
explained in the chapter 8.
2.- Interference by external light sources . If you expose the terminal to extreme light
conditions, the receptor element can be saturated, so it cannot detect the presence of
a finger.
Both permanently blocking the beam and saturating the receptor trigger an error
situation, in the event of which the Host will receive a notification (event Optical Barrier
Status, code 0xED ). The yellow LED on KBio2-Online’s User Interface (“Ready”) will

BioMax2 / KBio2-Online
Installation and Programming Manual
www.kimaldi.com Page 18 of 91
flash to indicate this. In this situation, you must press the green key (“Enter”) to initiate
biometric identification.
It will automatically return to normal when the beam of light is no longer obstructed or
the external interference is removed (event Optical Barrier Status, code 0x0D).
In order to activate this detection method, it is necessary to configure the following
parameters:
• Parameter$03 (CFG_Opt_T_Watchdog): it allows activation of the LED optical
barrier. So:
- LED operation: $80 (LED optical barrier on, obstruction timeout to 12.8 sec.).
If a second FIM module is connected, a special cable assembly allows using a Digital
Input to detect finger presence.
5.3.2. FIM Module
BioMax2 and KBio2-Online also allow finger presence detection by means of the
capacitive sensor embedded both in the OPP06 optical sensor and the capacitive sensors
that can be attached to the FIM5360 module (and later).
If two FIM devices are connected to a single BioMax2 or KBio2-Online, the same
detection mechanism can be used.
In order to activate this detection method, the following parameters must be correctly
configured:
• Parameter$03 (CFG_Opt_T_Watchdog): it allows to select the finger detection
method, or disable it altogether.
- Required value: $FF (Auto-On enabled).
• Parameter$1B (CFG_Serial_Port_Reader): it is necessary to configure UART1 for
a FIM module, at the correct baud rate.
- Possible values: $88 to $8B.
- Recommended value: $8A.
• Parameter$1D (CFG_Main_Reader): the FIM module must be declared here.
- Required value: $05 (FIM module on UART1 for the main reader).
Optionally, a second FIM module with Auto-On detection may be connected. In this
event, UART0 will be used:
• Parameter$1A (CFG_Serial_Port_Host):it is necessary to configure UART0 for a
FIM module, at the correct baud rate.
- Possible values: $88 to $8B.
- Recommended value: $8A.
• Parameter$1E (CFG_Aux_Reader): the second FIM module must be declared here.
- Required value: $04 (FIM module on UART0 for the auxiliary reader).

5.3.3. Setup and operation
Once configured, the BioMax2 or KBio2-Online electronics must be reset (use command
ApplyCFG), in order to start operation.
Optical barrier
The LED optical barrier will operate immediately, and it will be promptly generate a Key
Pressing event as soon as the infra-red beam is blocked. Any key value may be
announced, as configured through Parameter$05 (CFG_OPT_KeyCode). Its default
value is $41 (‘A’ : green key).
Upon finger detection, operation is suspended during a guard time period, which is
configured through Parameter$02 (CFG_OPT_T_GUARD). Such guard time may be
overridden from the application by disabling the optical barrier prior to communication
with the FIM module (Disable optical barrier). When done, re-enable operation (Enable
optical barrier) to resume detection.
FIM Auto-On
Automatic finger detection by the biometric sensor is a more complex process:
- Upon startup, a boot-up time is required for the FIM module. We may configure
such value through Parameter$0E (CFG_IDNT_-BOOTUP_TIME). The
recommended value depends on the FIM model and the database capacity.
- If a finger is presented during the boot-up period, an Optical Barrier Status event
showing status $FC, will appear.
- After boot-up, Auto-On starts automatically. If we force Enable optical barrier, we
get its current status in response. Value $00 is the correct operation status,
while $FD means that boot-up operation did not end correctly, so Auto-On is
not available. That can be due to a communication error (baudrate mismatch,
broken cable...) or to an old version of FIM that does not support this feature.
- Finger detection occurs when the finger is placed on the surface of the sensor. If
there is no clear perception of change (for instance, if the finger does is not
removed between one failed identification and the next retry), the finger is not
detected. Therefore, it is necessary to remove and re-place the finger for each
identification that we try. Upon detection, a Key Pressing event appears. The
value of the pressed key is configurable through Parameter$05 (CFG_
OPT_KeyCode), and its default value is $41 (‘A’ : green key).
- Upon finger detection, operation is suspended during a guard time period, which
is configured through Parameter$02 (CFG_OPT_T_GUARD). Such guard time
may be overridden from the application by disabling the optical barrier prior to
communication with the FIM module (Disable optical barrier). When done, re-
enable operation (Enable optical barrier) to resume detection.

BioMax2 / KBio2-Online
Installation and Programming Manual
www.kimaldi.com Page 20 of 91
- If Auto-On could not be enabled, an Optical Barrier Status event appears every
time we contact the FIM module through Send to UART.
- 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:
• Parameter$1C: UART2 is configured to link with BioMaxPlus-DB.
- Recommended value: $D1 (19200 baud communication)
• Parameter$12: 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)
• Parameter$13: 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)
