Operation
UCX – Activate
polling NXP-
UCODE-G2X Read
Protect
The UCX command starts the asynchronous transponder function (polling
operation) "ReadProtect" of all NXP-UCODE-G2X transponders in the field at the
respective antenna port. The polling "ReadProtect" 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.
