UKZ – Killing all
EPC transponders
(defined EPC code)
The UKZ command starts to kill all EPC transponders with the corresponding EPC
code located in the field. Several EPC transponders can be located in the write
area of the antenna when using this command. The kill command is only
performed if the kill password was previously written! The transponder can no
longer be addressed after a successful kill 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.
