Lock Tries
Sets the maximum number of times the lock algorithm is
executed before a response is returned to a Lock command. Valid
range is 1 to 254. The default is 3.
This setting is equivalent to the LOCKTRIES BRI attribute.
Select Tries
(Not supported by EPCglobal Class 1 Gen 2 tags) Sets the
number of times a group select is attempted. A group select is the
command that starts the identity process. Valid range is 1
(default) to 254.
This setting is equivalent to the SELTRIES BRI attribute.
Unselect Tries
(Not supported by EPCglobal Class 1 Gen 2 tags) Sets the
number of times a group unselects is attempted. Valid range is 1
(default) to 254.
This setting is equivalent to the UNSELTRIES BRI attribute.
Initial Queue
(EPCglobal Class 1 Gen 2 tags only) Sets the initial Q parameter
value used by the Query command. Valid range is 0 to 15. The
default is 4. If you know there is only one tag in the field, set this
attribute to 0 for best performance.
This setting is equivalent to the INITIALQ BRI attribute.
Session
(EPCglobal Class 1 Gen 2 tags only) Sets the command session
parameter to the corresponding EPCglobal Class 1 Gen 2 air
protocol command (default is QueryAdjust).
This setting is equivalent to the SESSION BRI attribute. For
more information on this setting, see the EPCglobal Class 1 Gen
2 documentation.
Field Strength
Sets the RF power level (measured as a percentage of maximum
power) for all antennas. Valid range is 1 to 100 (default).
Use this setting to antennuate the antenna field strength. In some
situations, full output power can cause unnecessary interference.
For example, if the tag is close to the antenna, full output power
might overload the tag and cause unreliable behavior.
