Important Notes
1.
There are six DIP switches on the back
of RS485 fingerprint reader, Switches
1-4 is for RS485 address, switch 5 is
reserved, switch 6 is at the End-Of-
Line for reducing noise on long RS485
cable.
2.
Set the odd number for IN reader, and
the even number for OUT reader (for
eg. For two readers for one door- the
RS485 address 1 is for IN reader, RS485
address 2 is for OUT reader)
3.
If RS485 fingerprint reader is powered
from InBio460Pro panel, the length of
wire should be less than 100 meters
or 330 ft.
4.
The External RS485 interface can
supply maximum 500mA current,
The RS485 fingerprint reader’s start-
up current is 240mA. So InBio460Pro
only can power two RS485 fingerprint
readers.
5.
If the cable length is more than 200
meters or 600 ft , the number 6 switch
should be ON as below:
Distance: More than 200 meters
