POWER, READER, AND I/O CONNECTION
Power Connection
Check the location of the power port.
- Connect the plus (+) line of DC 12V to the corresponding port (+12V).
- Connect the plus (-) line of DC 12V to the GND (-) port.
Reader Connection
- You can safely use other power sources for the reader than supplied from the specifi ed port; however, all
power sources should be connected to the common GND port. Failure of the GND grounding will cause a
transfer error of Wigand data to the controller due to a voltage difference.
Connect Wiegand Data Output 0 of the proximity reader to the D0 port and connect Wiegand Data Output
1 to the D1 port of P102(T).
