Tag Buffer
26 Functionality of the Embedded Modules
Tag Buffer Entry
In addition to the tag EPC data each entry contains meta data about how, where and
when the tag was read. When using the
Get Tag Buffer (29h) command you can choose to
get the following tag meta data returned with each tag extracted from the tag buffer:
Total Entry
Size
Field Size Description
18 bytes
(Max EPC
Length = 96bits)
EPC
Length
2 bytes Indicates the actual EPC length of the tag
read. Cannot exceed the Max EPC length
setting.
PC Word 2 bytes Contains the Protocol Control bits for the tag.
EPC 12 bytes Contains the tag’s EPC value padded with
trailing zeros if the size is less than the Max
EPC Length size.
Tag CRC 2 bytes The tag’s CRC.
68 bytes
(Max EPC
Length = 496bits)
EPC
Length
2 bytes Indicates the actual EPC length of the tag
read. Cannot exceed the Max EPC length
setting. Varies by Protocol:
• Gen2 = PCWord + EPC ID + CRC
• Other = EPC ID + CRC
PC Word 2 bytes Contains the Protocol Control bits for the tag.
EPC 62 bytes Contains the tag’s EPC value padded with
trailing zeros if the size is less than the Max
EPC Length size.
Tag CRC 2 bytes The tag’s CRC.
