Polling NXP-
UCODE-G2X
Change EAS
The UCC command starts the asynchronous transponder function (polling
operation) "Change EAS" of all NXP-UCODE-G2X transponders in the field at the
respective antenna port. The polling "Change EAS" 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.
1) These data are displayed in the order listed for each identified EPC
transponder.
