Chapter 4 — BRI Commands
Basic Reader Interface Programmer Reference Manual

This error indicates that the data read from the tag was invalid.
Error 3:
MEMOVRN<CRLF>
OK><CRLF>
This error indicates that the address used in the read command was not available on
the tag. This tag is only returned when the TAGTYPE attribute contains EPCC1G2.
Error 4:
DISPLAYERR<CRLF>
OK><CRLF>
This error indicates that the amount of data requested from the tag will not fit into
the output buffer in the BRI service. Clients should execute additional read
commands with smaller access requests. The BRI output buffer is 512 bytes.
Error 5:
The read command may also the error below when the NOTAGRPT attribute is ON.
NOTAG<CRLF>
OK><CRLF>
Examples:
These examples demonstrate how to use the READ command.
Example 1:
READ TAGID
This READ command with a TAGID parameter and no <DATA CONDITION>
parameter finds all tags in the field and returns a tag ID for each tag found. Each tag
ID is terminated with a <CRLF>. When all tags are returned, the BRI returns
OK><CRLF>. If no tags are found, the BRI returns NOTAG<CRLF>OK><CRLF>.
For example:
1234567890ABCDEFH<CRLF>
OK><CRLF>
Example 2:
READ TAGID WHERE TAGID=H1234567890ABCDEF
This READ command with a <DATA CONDITION> parameter defined above finds
a tag with the specified tag identifier. If a tag with the specified TAGID is found, the
BRI returns the tag identifier followed by OK><CRLF>. If the tag identifier is not
found, the BRI returns NOTAG<CRLF>OK><CRLF>. For example:
1234567890ABCDEFH<CRLF>
OK><CRLF>
Reader attributes affect the command responses:
If the IDREPORT attribute is enabled, each response is prefixed with the tag ID
or EPC code. For help, see
“IDREPORT” on page 91
.
Note:
The INT, HEX, and STRING data types in the [READ FIELD] parameters in
the some of these examples do not include the optional
memory_bank
parameter
that applies only to EPCglobal Class 1 Gen 2 tags. For help understanding the
memory bank, see the description of the
memory_bank
parameter on
“HEX(memory_bank:address, length)” on page 24
