Operation Instructions
After wiring the unit to a controller (POWER, GND, D0, D1), you should test
the reader.
To test the reader:
1.
Power up the reader. One beep is emitted and then it begins an auto-
calibration procedure. After 2 seconds, the reader enters working mode.
2.
Present the appropriate type of credential to the reader. A short beep is
emitted, indicating that the credential is read properly.
