3.6 Connection with Wiegand Readers
C3-100 can connect two Wiegand readers in the one-door two-way mode. C3-200
provides four readers, which can be connected in the two-door two-way mode.
C3-400 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 C3 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.
