1. Description
CV-940 is a Wiegand biometric reader for indoors access
control applications. It offers storage of up to 9500
ngerprints and a programmable Wiegand Output
(8 to 128 bits).
Conguration of the readers and ngerprint enrollment
is done through PC Software. Connection between the
biometric readers is RS485 and it is used for ngerprint
transfer and conguration. When used with third party
controllers, the connection between the Biometric readers
and the PC is done through a RS485 converter. Only one
converter is needed per system (one converter for 1, 2,
3...30, 31 Biometric readers.
The tamper switch output can trigger the alarm system, if an
attempt is made to open or remove the unit from the wall.

5. Connecting Biometric Readers to CV-350 Controller
• The Biometric readers can be connected to virtually
any controller that conforms to Wiegand format
standards (standard Wiegand 26bit or self-dened
Wiegand).
• The lines D0 and D1 are the Wiegand lines and the
Wiegand Number is sent through them.
• The RS485 line (A, B) is used for ngerprint transfer
and reader settings.
• The Biometric readers must be powered from
the controller.
• If you use a different power supply for the biometric
reader, connect the GND from the both devices to
ensure correct transfer of the wiegand signal.
• When you have connected the reader and powere is on,
the LED should ash an orange light + 2 beeps. This
lets you know it’s on and ready for use.
• Fingerprint enrollment is done from the PC Software.
Connection between the Biometric readers and the PC
must be established.

(5m) max.
• The Biometric readers are connected through a 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 a RS485 HUB to connect.
• The RS485 Line should be congured in the form of a
daisy chain, NOT in a form of a star. If a 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
3,280 ft. (1 km) max. / 32 Units

termination, cable type...) so recommendation is to
keep stubs shorter than 16 1/2 meters, keeping
in mind that this can cause 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 RS485
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.

• The Biometric readers communicate with each other

a Converter.
• The RS485 Line should be congured in the form of
a daisy chain, NOT in a form of a star. Keep the stubs
from the RS485 backbone as short as possible (not
more than 16 ft. (5 meters).
• Only one converter per installation is needed,
not per reader.
