Application Tag Commands

Command Set

95

Write Tag Data (24h)

to write 0x12345678 into the Reserved Memory Bank starting at

Word address 0x00000002 (Access Password)

The response contains the number of tags found matching the Select criteria specified
and the number of embedded command operations which succeeded and failed. Use

Get

Tag Buffer (29h)

to access the tag EPCs and Tag Read Meta Data for the Tags Found.

Tags in the buffer may or may not have had successful execution of the embedded
command on them:

Note

Depending on the Gen2 Session/User Mode used the Operations
Succeeded/Failed counts can be misleading since in Session 0, for
example, the tag may respond many times during an inventory round and
the command may be attempted many times. This would result in counts
higher than the actual number of tags the operation succeeded or failed on.
The above commands were run in User Mode = Portal.

Note

When embedding write operations, including Lock and Kill, in Read Tag
Multiple the Read TX Power will be used for the entire operations: inventory
and the write. The power will not switch to the Write TX Power for each Write
operation.
