Lock Trie s Sets the maximum number of times the lock
algorithm is executed before a response is
returned to a Lock command.
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.
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 unselect is
attempted.
ID Tries Sets the maximum number of times the reader
executes the identify algorithm before a response
is returned to a Read or Write command.
In practice, this is the number of times a tag ID
attempt is made for the antenna.
This setting is equivalent to the IDTRIES BRI
attribute.
Initial Q (EPCglobal Class 1 Gen 2 tags only) Sets the
initial Q parameter value used by the Query
command.
Ifyou 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.
Field Strength dB Sets the RF power level (in dBm) for each of the 4
antenna ports.
Use this setting to attenuate 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.
This setting is equivalent to the
FIELDSTRENGTH BRI attribute
