• 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 16 ft. (5 meters).
• Only one converter per installation is needed,
not per reader.
