4. OPERATION
Reader operation without external indication control:
1. When power is supplied and there's no card in the working zone, the LED shines red.
2. On card approach, its number is acquired. If done successfully, the LED turns green for a
short time, then switches itself off, at the same time a short beep also sounds.
3. While the card remains within the reader working zone, the LED stays off.
External indication control for the buzzer and red/green colours of the LEDs is done by shorting
the corresponding terminal (BEEP (blue), LED R (yellow), LED G (green)) to the common
ground terminal (GND (black)).
