Tag/Message Buffer
In basic communication protocol, the Encompass 4 Reader does not provide tag mem-
ory storage beyond the quantity required for uniqueness checking. This feature allows
adequate buffering of tag data under normal operating conditions. The Encompass 4
Reader cannot operate as a stand-alone component. When the buffer fills, subsequent
tag IDs will be lost.
In error correcting protocol (ECP), a buffer of up to three additional tag reads will be
held in case a host system is unable to acknowledge tag reads in real time.
