URB – EPC
Bulk reading
The command URB starts a reading of EPC transponders over a predetermined
period of time. The EPC of all detected transponders is reported after the
completion of the time.
1) These data are displayed in the order listed for each identified EPC
transponder.
2) The response of the transponder is optional and only appears at result "00".
3) The result and Ex flag is only available in the first transmitted message in
messages with several frames.
Example:
