Gen2 Tag Commands
124
Get Tag Data
The following example will attempt to read the Kill Password (the first 2 words) from
Reserved Memory. It will read this data from a tag matching the following criteria for a
max timeout of 1000 ms.
Memory Bank = User Memory.
Starting Address = bit 32
Select Data = 0x1234
The Reserved Memory bank is not locked so the Access Password is zero
If Option=0x00 or 0x01 is used then the unused
Tag Singulation Fields (including the
Access Password) must be removed from the request.
The response to this Read Data command example is:
Read Tag Data Response
The length field of the data returned is 2 times the WordCount value in the original
command, because the return packet length is counted in bytes, plus 1 byte for the
Option specified.
Get Tag Data and Meta Data
In addition to getting the tag data returned you can also get Tag Read Meta Data for the
found tag. This version of Read Tag Data requires bit 4 of the Option flag to be set and
takes an additional Metadata Flags field which defines what metadata will be returned.
The following table lists the supported values for these fields.
