Within the two seconds timeout, where the red LED is blinking, 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 of the red LED a different transponder is detected, the complete sequence restarts immediately.

SUSPEND MODE
The USB version of the reader supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, then the reader
is turning off most of its power consuming peripherals. During this operation mode, no detection of transponders is possible and all
LEDs are turned off.
Once the host is resuming to normal operation mode, this is also signaled via the USB bus. Therefore, the reader will resume to normal
operation too.
