Operation
UCE - Activate
polling NXP-
UCODE-G2X EAS
alarm
The UCE command starts the asynchronous transponder function (polling
operation) "EAS alarm" of all NXP-UCODE-G2X transponders in the field at the
respective antenna port. The polling "EAS alarm" is executed as long as it is not
ended or a reset is executed.
Transponder messages only appear if NXP-UCODE-G2X transponders are actually
moved in the field. The polling is briefly stopped for intermediate read requests
and is continued after the action.
Example:
>> UCE01
<< uce000
