4. Normal Operating Mode
Idle State (no Transponder detected):
In idle state the reader is searching permanently for a Transponder. In this case the red
LED is active.
Transponder detected:
After a Transponder is detected by the ID CPR.03.20-CD the data's are transmitted via
data-/clock interface once and the beeper sounds for a short time. At the same time the
red LED turns off for a period of 2 sec.
To transmit the data's a second time the Transponder must leave the detection field of the
ID CPR.03.20-CD for more then 1,5 seconds.
UID Length Error
If the Transponder UID is shorter than configured in ID CPR.03.20-CD a length error is
signalized with 2 short beeps. In this case no data's are transmitted via data-/clock inter-
face.
