Initial Queue; Field Strength; Session; Enable Antenna Port N - Intermec IF5 User Manual

Chapter 3 — Developing and Using RFID Applications

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
(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.

Field Strength

Sets the RF power level (measured as a percentage of maximum
power) for all antennas. Valid range is 0 to 100 (default is 100).
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.

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.
Enable Antenna Port
Enables or disables the antenna connected to antenna port n.
Check the check box to enable that antenna. Antenna Port 1 is
enabled by default.
If more than one antenna is enabled, the antennas always fire in
sequence numerically (1, 2, 3, 4). To change this sequence, you
need to set the ANTS BRI attribute. For more information, see
the BRI programmer's reference manual.
