Connect the lines D0, D1, Gnd and +12V to the third party controller.
Connect the RS485 Line (A, B) to the converter. Connect the converter in the PC.
Fingerprint enrollment is done from the PC Software. Connection between the Biometric readers and the PC must be established.
The Biometric readers communicate with each other with a RS485 and with the PC Software through a Converter.
The RS485 Line should be configured 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 5 meters)
Only one converter per installation is needed, not per reader.
