biometric access controller is designed to meet various requirements for a robust integrated security
solution for access control and time & attendance.
This user-friendly device is capable of storing up to 10,000 to 50,000 cardholders. Depending on
the total number of cardholders, up to 10,000 to 50,000 events and alarms can be buffered in the
memory so that they can be uploaded to the PC when communication is established.
With a built-in 4” proximity card reader, a keypad for Personal Identification Number (PIN)
verification and a fingerprint recognition module, the state-of-the-art device allows users to utilize
any combination of RF card / PIN, password and fingerprint verification depending on the desired
level of security and convenience for individual users or different groups of users. The
FINGER007SRB uses PRG2000B to encode fingerprint information onto the card.
The IDTECK FINGER007SRB is capable of controlling one External Reader for Anti-Pass Back
application. Four independent input ports can be utilized for a wide variety of applications including
Exit Buttons, Door Contacts, PIR Sensors and Fire Detection equipment. Actions to be taken and
time settings can be programmed with the front keypad or via the intuitive Windows-based software
program.
The intelligent access controller has the capability to supervise the input and report any
disconnection or malfunction of the input to the host or other devices. Events from high priority input
devices such as Fire Alarm Sensor, Emergency Key, etc. can be reported to the host prior to all
other events. You can use the unit standalone but you can also connect it to the network via RS232
or RS422 communication or on an Ethernet network through an optional TCP/IP module.

6. PRODUCT OVERVIEW
6.1. FUNCTIONS
Standalone Operation
The FINGER007SRB is capable of having two readers (i.e. One built-in reader inside the unit and an
External Reader connectable using the External Reader port). The unit receives card data signals
from the Proximity Readers and determines whether or not to unlock the door. When an input signal
is sent, for example from and activated sensor or if the Exit Button pressed, the controller generates
and logs an appropriate response. All events are kept in its memory and sent to the PC. The access
controller is a true standalone device that in the event of a malfunction, will not affect other units,
even if used in conjunction with one another.
Operation with PC
All event transactions can be managed via the PC. The data transmitted from the controller can be
processed, displayed (In the form of cardholder status, alarm status, etc.) and stored on the PC.
Data Retention
All user information and event/alarm data are retained even in the event of Power Failure unless the
memory or the device itself is damaged.
Keypad
The built-in Keypad and LCD let you perform manual programming without connection to the PC.

10
Anti-Pass Back
Anti-Pass Back is a function that is used to prevent a user entering an area by using their card and
passing that card back to another person to use. If the Anti-Pass Back is applied, cardholders cannot
gain entry or exit twice in a row, and even if someone tailgates someone into the controlled area
without going through the proper authentication procedure, he or she will not be able to gain access
when exiting the area. If this is the case, the FINGER007SRB generates an error message without
granting access and then stores an Anti-Pass Back error record in the memory. You can also
program the FINGER007SRB to generate certain output signals in the event of an Anti-Pass Back
error.
External Input / Output
The FINGER007SRB has 4built-in inputs and 4outputs (2Relay Outputs and 2TTL Outputs) which
can be used for a wide variety of purposes and applications. For example, the input ports can be
used for interface with external devices such as Request-To-Exit Button, Fire Detection Sensor, etc.
while the relay output ports can be connected to a Door Lock and/or an Alarm System. When you
use Weigand output function, 26 Bit Weigand will be generated from dual TTL output.
Time Schedule
You can program 10 Time Schedules and apply one Time Schedule to each user. Each Time
Schedule has 8 different time zones from Monday to Sunday (7 Time Zones) and one holiday. Each
time zone has 5 different time codes so you can program 5 different time codes to each day. Also you
can program Time Schedule for individual inputs and outputs. Note that the Time Schedule for input
is activated time code for input device so that the input is activated during the time code on this Time
Schedule. Each Time Schedule is linked to one of holiday schedule and this linked holiday only
validates to holiday time code of the Time Schedule.
Access Time Limitation for Cardholders – You can assign a time schedule code to each
Cardholder during the card registration process. Cardholders are granted access only during the time
defined in the assigned time schedules. If a Cardholder attempts to gain access out of the set time,
access will be denied with a time schedule error.
Operating Time Limit for Input/ Output Ports – If you assign a time schedule code to an input/
output code, the Input/ Output Port generates constant output signals during the set time.
(For example, this feature can be used to keep a door open for a certain period of time.)
Operating Time Limit for Authentication Modes -If you set the FINGER007SRB to the RF + P/W

11
mode and apply a time schedule code for the Authentication Mode, the FINGER007SRB will operate
in the RF-Only mode (Using RF Card verification alone) during the set time and shift into the RF +
P/W mode (Using both RF Card and Password) out of the set time.
Holiday Schedule Setup
Excepting Sunday, you can program 32 holidays to one Holiday Schedule. Each Holiday Schedule is linked
to one time schedule which has time code for holidays. So you can program all holidays to Holiday Schedule
and the time code for holidays is programmed to holiday time zone of time schedule.
Example: A: Holiday Schedule 01 linked to Time Schedule 01,
Holiday Schedule 02 linked to Time Schedule 02.
B: Holiday Schedule 02 linked to Time Schedule 01,
Holiday Schedule 01 linked to Time Schedule 02.
Door Open Alarm & Forced Door Open Alarm
The FINGER007SRB can report the open status of the door if the door is not closed within a certain
length of time (default: 3 sec) after the door is opened following a normal access procedure. (If this is
the case, an alarm signal can be sent to the output port and the alarm event will be saved in the
event buffer so that it can be uploaded to the PC when communication is established.) If the door
contact sensor detects forced opening of the door, the Forced Door Open Alarm can be generated.
Duress Alarm
In the event of duress, you can enter the 2Digit Duress Password and press <ENT> and open the
door using general process. If your access is granted, the door will be opened as usual but duress
output will be generated and an alarm event will be sent to the PC.
Weigand Output Function
You can use a Weigand Output Function in the "SETUP MODE F2".
Card Encoding
The FINGER007SRB uses the PRG2000B KIT to encode the fingerprint onto the card.
(Please refer to the PRG200B KIT manual for more detail.)

7.2 CHECK POINT DURING INSTALLATION
7.2.1 TERMINATION RESISTOR
Termination Resistors are used to match impedance of the network to the impedance of the
transmission line being used. When impedance is mismatched, the transmitted signal is not
completely absorbed by the receiver and a portion of signal is reflected back into the transmission
line.

17
The decision whether or not to use Termination Resistors should be based on the cable length and
data rate used by the communication system.
For example, if you use 9,600 baud rate and 1,200m length of cable, the propagation velocity of
cable is 0.66 x speed of light (This value is specified by the cable manufacturer), if we assume the
reflections will damp out in three round trip up and down the cable length, the transmitted signal will
stabilize 18.6us after the leading edge of a Bit. Since the data Bit is captured in the middle of the Bit
which is approximately 52us after the leading edge of a Bit. The reflection stabilizing time 18.6us is
much before the center of the Bit therefore the Termination Resistors are not required.
However, if you install the cable to maximum length, the impedance of cable and network is
mismatched and the transmitted signal is overlapped by the reflected signal. In this case, it is
recommended to add Termination Resistors to the end of the receiver lines. A 120Ωresistor can be
used for Termination Resistor in parallel between the receiver lines “A” and “B” for 2 wires RS485
system or “RX+” and “RX-” for 4 wires RS422 system. A Termination Resistor of less than 90Ω
should not be used and no more than 2 terminations should be used in one networking system.
7.2.2 HOW TO CONNECT TERMINATION RESISTORS
Figure: Termination Resistors for 2 Wire RS485 Communication System
Figure: Termination Resistors for 4 Wire RS422 Communication System
7.2.3 GROUNDING SYSTEM FOR COMMUNICATION CABLE
We recommend to using proper Grounding System on the communication cable. The best method
for Grounding System is to put the shield wire of the communication cable to the 1st class earth
grounding; however it is not so easy to bring the earth ground to the communication cable and also
the installation cost is raised.
There will be three grounding point where you can find during installation;
1) Earth Ground

18
2) Chassis Round
3) Power Ground
The most important point for Grounding System is not to connect both ends of shield wires to the
Grounding System; in this case there will be a current flow through the shield wire when the voltage
level of both ends of shield wire is not equal and this current flow will create noise and interfere to
communications.
For the good grounding, we recommend to connecting only one end of shield wire of communication
cable to Grounding System; If you find earth ground nearby, then connect one end of shield wire to
earth ground; If you do not have earth ground nearby, then find chassis ground and connect one end
of shield wire to chassis ground; If you do not find both earth ground and chassis ground, then
connect one end of shield wire to power ground. (GND of FINGER007SRB)
Note: if the chassis ground is not properly connected to the earth and floated from the ground level,
then grounding to the chassis ground will give the worst communication; in this case we recommend
to using power ground instead of chassis ground.
Figure: Grounding System
7.2.4 REVERSE DIODE CONNECTION
If you connect an inductor (Door Locks or Alarm Device) to the output relays, there will be a high
surge voltage created while the inductor is turning on and off. If you do not connect Reverse Diode,
the surge voltage will transfer and damage to the electronic circuit of the controller. It is strongly
recommended to add a Reverse Diode between the inductor coils to absorb this surge voltage.

:
Before mounting the FINGER007SRB unit to the Wall Mount bracket, an operational test
of the unit should be completed, because the locking pins will lock the unit to the Wall
Mount. Removing the unit from the Wall Mount bracket after it has been snapped in
place may cause damage to the bracket and prevent reattachment.
