Operation
URY - Read data
range (defined EPC
code)
The URY command starts the reading of a defined data range of the current EPC
transponders which have a defined EPC code. Several EPC transponders can be
located in the reading area of the antenna when using this command.
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: Read access password
