considered that the starting current is bigger, there are only four readers can connect for power supply
through the EXT RS485 interface. So the power of control panel can only connect up to 4 readers.
If RS485 reader is connected externally and shares the power supply with the device, it is recommended that
the connection between the EXT RS485 port and the reader be no longer than 100m. Otherwise, it is
recommended that using a separate power supply for the reader.
For some of the devices with much greater consumption, we suggest to use the separately power supplies, to
make sure the steady operation.
Connection with Wiegand Readers
The InBio160 Pro can connect two Wiegand readers in the one-door two-way mode. The InBio260 Pro
provides four readers, which can be connected in the two-door two-way mode. The InBio460 Pro provides
four readers, which can be connected in the two-door two-way or four-door one-way mode.
The Wiegand interfaces provided by the InBio160/260/460 Pro series can be connected to different types
of readers. If your card reader does not use the voltage of DC 12V, an external power supply is needed. A
reader should be installed at a height of about 1.4m above the ground and at a distance of 30-50mm
away from a door frame.
