Page 108 highlights

Chapter 4 - BRI Commands SELTRIES SESSION TAGTYPE When SCHEDULEOPT is set to 2, inventory behaves just like SCHEDULEOPT=1 except that any consecutive inventory rounds on the same antenna will toggle between targeting tags in the A state and tags in the B state. This value only applies to EPCC1G2 tags and is useful when dealing with tags that exhibit excessive persistence. For example, some battery powered EPCC1G2 tags have infinite persistence in sessions 1, 2, and 3. Once inventoried from A to B, these tags will stay in the B state and may not be identified if the reader does not run an inventory round targeting B tags. Sets the number of times a group select is attempted. A group select is the command used to start the identify process. Range is 1 to 254. Default is 1. ATTRIBUTE SELTRIES=1 Note: This attribute can be used for EPCglobal Class 1 Gen 2 tags, but is not recommended. Sets the command session parameter to a corresponding EPCglobal Class 1 Gen 2 air protocol command. You can set this attribute to 0, 1, 2, or 3. Default is 2. The following example specifies an EPCglobal Class 1 Gen 2 Select command: ATTRIBUTE SESSION=0 For details about SESSION, see the EPCglobal Inc. specification, EPC™ RadioFrequency Identity Protocols Class-1 Generation-2 UHF RFID Protocol for Communications at 860 MHz-960 MHz Version 1.1.0. Defines the types of RFID tags used in an application. Certain performance improvements can be realized if it is known ahead of time what types of tags are in use.

Basic Reader Interface Programmer Reference Manual
When SCHEDULEOPT is set to 2, inventory behaves just like SCHEDULEOPT=1
except that any consecutive inventory rounds on the same antenna will toggle
between targeting tags in the A state and tags in the B state. This value only applies
to EPCC1G2 tags and is useful when dealing with tags that exhibit excessive
persistence. For example, some battery powered EPCC1G2 tags have infinite
persistence in sessions 1, 2, and 3. Once inventoried from A to B, these tags will stay
in the B state and may not be identified if the reader does not run an inventory
round targeting B tags.
SELTRIES
Sets the number of times a group select is attempted. A group select is the command
used to start the identify process. Range is 1 to 254. Default is 1.
ATTRIBUTE SELTRIES=1
SESSION
Sets the command session parameter to a corresponding EPCglobal Class 1 Gen 2
air protocol command.
You can set this attribute to 0, 1, 2, or 3. Default is 2.
The following example specifies an EPCglobal Class 1 Gen 2 Select command:
ATTRIBUTE SESSION=0<CRLF>
For details about SESSION, see the EPCglobal Inc. specification,
EPC™ Radio-
Frequency Identity Protocols Class-1 Generation-2 UHF RFID Protocol for Communications at
860 MHz–960 MHz Version 1.1.0
.
TAGTYPE
Defines the types of RFID tags used in an application. Certain performance
improvements can be realized if it is known ahead of time what types of tags are in
use. Follow this syntax:
ATTRIBUTE TAGTYPE=
identifier
[,
identifier
...]
where
identifier
is one of the values listed in the next table.
Note:
This attribute can be used for EPCglobal Class 1 Gen 2 tags, but is not
recommended.
