from the minimum RF output power to maximum RF output power or until
it finds a tag, increasing the RF power of 1 dB every 500ms with fixed Q
selection algorithm and Q=0. It is an ‘on request’ function which
temporarily
suspends the ‘continuous’ mode.
•
‘RF Sensitivity’ test: allows the user to easily and quickly test the minimum
RF input sensitivity needed to read a tag in a fixed position. The reader
sweeps from the minimum RF input sensitivity to maximum RF input
sensitivity or until it finds a tag, increasing the RF sensitivity of 1 dB every
500ms with fixed Q selection algorithm and Q=0. It is an ‘on request’
function which temporarily suspends the ‘continuous’ mode.
•
Read Reflected Power: allows the user to read the reflected power of the
antenna at a given frequency to check the antenna connection.
•
Read RSSI: allows the user to read the signal strengh received by the
antenna at a given frequency to check the presence of external RF sources.
The
BLUEBOX
integrates a reconfigurable RF carrier leakage canceler feature
which allows the usage of the reader in many different environments and
configurations. The RF carrier leakage canceler adaption is done at every power
on and during normal operations of the reader based on RF tuning configuration
parameters described in next sections.
Only items 5227U with hardware version 2 and firmware version
2.xx integrates the reconfigurable RF carrier leakage canceler
feature!

General Parameters
This section provides details on the configurable general parameters of the
BLUEBOX
.
The general parameters are managed through the OD 2200h.
The changed general parameters become effective only after a
reset of the
BLUEBOX
. Reset the
BLUEBOX
using the ‘Reset
Device’ command or via a hardware reset.
Value Definition:
Sub-index 00h contains the number of valid object entries within the record. The
number of valid objects entries shall be the number of the general configuration
parameters. Its value is 02h.
