Transponder recognized
As soon as the reader has recognized a transponder type included in the
configuration, the beeper issues a short noise (approx. 20 ms). This function offers
the user an acknowledgement that the transponder has been recognized and the
service engineer an option for checking the reading range.
The transponder data is output once only. Further data output is only possible if the
transponder has left the detection range for more than 1.5 secs and is then read
again.
LED displays:
As soon as a transponder is recognized the red LED extinguishes and waits for
timeout (2 secs) at the digital input LED red or LED green.
If no input to the LED control is active:
Red LED goes on again after timeout is complete.
–
Input for LED red:
As soon as the input becomes active the red LED lights up.
Input for LED green:
As soon as the input becomes active the red LED lights up and the red LED
extinguishes.
Once the input has become inactive the green LED extinguishes and the red
LED lights up.
UID length error
If the reader has recognized a transponder with a UID having less bits than the
sum of D_START and D_LGT a UID length error is signalled (2 * short beep).
In this case no data is output via the Data / Clock interface and no signalling takes
place via the LED.
Example:
Transponder to ISO 14443-A, with UID length of 4 bytes (32 bits)
D_START = 16, D_LGT = 24 Þ D_START + D_SLGT = 40 Þ UID not output.
