Important Notes
1.
There are six DIP switches on the
back of RS485 fi ngerprint reader,
Switches 1-4 is for RS485 address,
switch 5 is reserved, switch 6 is 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 fi ngerprint reader is pow-
ered 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 fi ngerprint reader’s
startup current is 240mA. So InBio-
460Pro only can power two RS485
fi ngerprint 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
