3.2 Enumeration (USB Only)
This is only applicable for the USB version: Once the device has been
powered up, it is waiting for completion of the enumeration by the USB
host. As long as the device is not enumerated, it is entering a minimum
power consumption mode.
3.3 Initialization
After powering up and enumeration (in USB mode), the device is turning on
the built-in transponder reader logic. Some transponder reader modules
need some kind of initialization, which is performed in this step.
3.4 Normal Operation
As soon as the device has completed the initialization, it is entering normal
operation. During normal operation the device is searching for a
transponder continuously.
3.5 Detection of a Transponder
If a transponder is detected by the reader, following actions are performed
• Send the ID to the host. By default, the USB device sends by
emulating keystrokes of a keyboard.
Within the two seconds timeout, the transponder, which just has been
recognized will not be accepted again. This prevents the reader from
sending identical IDs more than one time to the host.
If during the two seconds timeout a different transponder is detected, the
complete sequence restarts immediately.
