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-defined
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 fingerprint 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 flash 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.
