If the biometric reader is installed and used outdoor, the
reader MUST be tted with the ATPD-MINI polycarbonate
cover available in our accessories in order to protect the
sensor from direct rainfall. The operating temperature
of the product is between -15ºC - +50ºC. If the reader
is installed in an environment where the temperature
can drop below -10ºC or/and if the sensor could only be
exposed to direct sunlight, it is strongly recommended to
install the reader inside a third party sealed wall mount
box (tted with additional heater if very low temperature)
to keep a constant sensor level performance. Camden™
cannot guarantee the functionality of the product if
measures and advice before are not followed.
It is also strongly recommended to use double technology
biometric readers when use outdoor to offer rst higher
security but alsothe possibility to use different readers
depending on users.

• The Biometric readers are connected through RS485
bus. The same RS485 bus that the CV-350 controllers
are connected to.
• Maximum units in one network (CV-350 + Biometric
readers) is 32.
• If there are more than 32 units in one network, please
utilize RS 485 HUB to connect.
• The RS485 Line should be congured in the form of a
daisy chain, NOT in a form of a star. If star must be
used in some points, keep the stubs from the RS485
backbone as short as possible. Maximum length of
the stub is dependant of the installation (total number
of devices in RS485 line (total cable length,

termination, cable type...) so recommendation is to
keep stubs shorter than 5 meters, keeping in mind that
this can be possible reason for errors in communication
with PC software
• The cable must be twisted and shielded with a
min. 0.01” in (0.2 mm) 2 cross section.
• Connect the ground (0V) of each unit in the RS 485
Line using a third wire in the same cable.
• The shield of the communication cable between two
devices must be connected to the EARTH from ONE
side of the RS485 Line.
• Use the side that has earth connection to the building’s
grounding network.

• When all the controllers are connected via TCP/IP, then
the RS485 network becomes local (from Reader 1 to
the Controller then to the Reader 2).
• Connect the readers directly to the Rs485 terminals in
each controller.
50m
max.
• If the distance Reader-Controller is high (50 meters)
and if the communication with the reader can not be
established, then terminate the RS485 network by
closing the jumper in the CV-350 Controller or as
described in chapter 4.

User Manual
10. WIEGAND Protocol Description
The data is sent over the lines DATA 0 for the logic “0”
and DATA 1 for the logic “1”. Both lines use inverted
logic, meaning that a pulse low on DATA 0 indicates a “0”
and a pulse low on DATA 1 indicates a “1”.When the lines
Fig. 9.12 a
Fig. 9.12 b
Fig. 9.12 c
are high, no data is being sent. Only 1 of the 2 lines
(DATA 0 / DATA 1 ) can pulse at the same time.
Example: data 0010....
00
5V
D0
0V
1 ms
100 us
5V
D1
0V
Data bit 0 = approximately 100 us (microseconds)
Data bit 1 = approximately 100 us (microseconds)
1
Time between two data bits: approximately 1 ms
(millisecond). Both data lines (D0 and D1) are high.

Description for the 26 bits Wiegand format
Each data block consists of a first parity bit P1, a fixed 8 bits header, 16 bits of user code and a 2nd parity bit P2. Such
a data block is shown bellow:
Parity bit (bit 1) + 8 bits header + 16 bits user code = 2 bytes + Parity bit (bit 26)
P1 XXXXXXXX XXXXYYYY YYYYYYYY P2
Example: 170 31527
1 1 0 1 0 1 0 1 0 0 1 1 1 1 0 1 1 0 0 1 0 0 1 1 1 0
Note: Parity bits are calculated as follows:
P1 = even parity calculated over the bits 2 to 13 (X) P2 = odd parity calculated over the bits 14 to 25 (Y)
E A A A A A A A A B B B B B B B B B B B B B B B B O

12. Troubleshooting
CV-940-20 Series
The Red Led on the Biometric Reader
is blinking all the time
The keypad of the Biometric Reader
is not working
Enrollment from desktop reader can be
done, but the Fingerprints are not sent
to all Biometric Readers in the network
The Biometric Reader is not powered
ON. The tricolour LED is OFF.
Fingerprint (or PIN Code) is recognized
(the tricolor LED is green), but the
controller reports other ID number and
the access is denied
Electro static discharge influences the
Fingerprint Scan.
PIN Codes are working correctly, finger
scan does not work. The triocolour LED
is OFF.
There were 15 unsuccessful attempts of authentication (Finger or PIN).
The Red LED will turn off after the first accepted finger or PIN.
The operation Mode of the Biometric Reader is set as “Finger”. Please
select “Keycode OR Finger” mode
• Check the Ser.No of the Readers.
• Check if proper termination is done as described before
• Check if the Communication wires (A & B) are properly connected
to the reader
Check the power Supply (red & black wire)
• If the user is not deleted from the reader and the same user is
enrolled again with new ID, the reader will recognize the finger with
the first ID. To resolve this, delete all users from the reader and
upload all users to the reader
• Check the Wiegand Bus (yellow & white wire)
• Check if the ground of the controller and the Biometric
Reader is the same
• Check if the length between Biometric Reader and the
controller is less than 50 m
Connect the housing of the Biometric Reader to the earth wire
• Fingerprint Sensor malfunction
• Check the Sensor position and its physical condition Reset the
system. Contact your installer
• Check if fingerprint reading area is dirty. Do not clean the
Reader reading performance is
decreased
device with any form of liquid. Use soft and dry cloth only
Reading area is damaged. If the damage is minor, try to calibrate
the sensor
• Retry after drying the wetness of your finger
Fingerprint is not recognized normally
• When your finger is too dry, touch your forehead and try again
When you have a cut on your registered finger, register another
fingerprint
