Indicator LEDs:
The three indicator LEDs on the reader part together with the LED on the controller part are
used to display error states at the start-up of the reader system. LSB (bit 0) is the controller LED
and reader LEDs D1 – D3 are bit 1 – bit 3. If an error occurs during the start-up the LEDs are
slowly flashing the error code.
