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 AMC2-4W provides four ports for connecting a maximum of 4 readers with Wiegand
interfaces. Each interface is connected using a 10-pin pluggable screw - refer to Connecting
Diagrams, page 43 .

Readers are addressed according to their respective interface numbers.
