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.

3.6 Suspend Mode (USB Only)
The USB version of the transponder reader supports the USB suspend
mode. If the USB host is signaling suspend via the USB bus, the
transponder reader is turning off most of its power consuming peripherals.
During this operation mode, no detection of transponders is possible. Once
the host is resuming to normal operation mode, this is also signaled via the
USB bus. Therefore, the transponder reader will resume to normal
operation, too.

Final Compliance of end product
The integrator is responsible for the final compliance of the end product
including this certified transmitter module. CFR 47 §15.101 give guidance
in terms of applicable equipment authorization procedures of different end-
products. Typically compliance to subpart 15 B (§15.107 and 15.109) Class
A or B including verification of the subpart 15 C compliance (field strength
of fundamental and out-of-band emissions) of the transmitter parameters
apply.
Simultaneous transmission
When the host product supports simultaneous-transmission operations the
host manufacturer needs to check if there are additional RF exposure filing
requirements due to the simultaneous transmissions. When additional
application filing for RF exposure compliance demonstration is not required
(e. g. if the TWN4 MultiTech 3 module in combination with all
simultaneously operating transmitters complies with the RF exposure
simultaneous transmission SAR test exclusion requirements), the host
manufacturer may do his own evaluation without any filing, using
reasonable engineering judgment and testing for confirming compliance
with out-of-band, restricted band, and spurious emission requirements in
the simultaneous-transmission operating modes.
