Operation
UAL – Lock EPC The UAL command starts the asynchronous lock EPC (polling) of defined EPC
transponders at the respective antenna port. The polling lock EPC is executed as
long as it is not ended or a reset is executed. Transponder messages only appear
if EPC transponders are actually moved in the field. The polling is briefly stopped
for intermediate read requests and is continued after the action.
1) These data are displayed in the order listed for each identified EPC
transponder.
Example: Lock kill password (Payload 0x0C0300 Permalock=1)
>> UWW0100000000000000000002FEFEFEFE
<< uww000000101000005358004D9DDB233083000
Kill password written
>> UAL010000000000030C
<< ual000
Polling successfully initiated
 Since Permalock was set, the kill password cannot be read or written after the
locking process!
