Wiegand Interface for Card Readers

Notice!
If your reader requires a voltage other than 12V or is the power
consumption more than 200 mA then it will require an external
power supply.
The AMC2-4WE provides four ports for connecting a maximum
of 4 readers with Wiegand interfaces. Each interface is
connected using a 10-pin pluggable screw connector (S2, S7,
S14, and S19) - refer to Connecting Diagrams, page 48.

These interfaces are point-to-point connections, and each can
support only a single reader with a maximum cable length of
90 m (300 ft) for 24 AWG or 150 m (500 ft) for 22 AWG. Readers
are addressed according to their respective interface numbers.
