information
Diagnostic result
Contains the result for communication diagnostic in 4-digits hexadecimal.
0000 hex : Normal communications
0001 hex : Insufficient power to send
0002 hex : Insufficient power to receive
0003 hex : Too much noise
0004 hex : Insufficient signal-to-noise ratio.
•
The value is 0000 hex (fixed) when the communications result shows normal
communications.
•
If a communications precaution is given for the communications result, the result
indicates the cause.
Send power level
Contains the send power level for communication diagnostic in 4-digits hexadecimal.
0 to 10
•
This is the corrected lowest value of DAC (10-bit) where communications with the RF Tag
were successful out of the multiple send power levels.
•
The value is 0000 hex (fixed) when the communications result shows an RF Tag missing
error.
Receive power
level
Contains the receive power level for communication diagnostic in 4-digits hexadecimal.
0 to 10
•
This is the corrected ADC (10-bit) value for response communications with the RF Tag.
•
The value is 0000 hex (fixed) when the communications result shows an RF Tag missing
error.
Noise level
Contains the noise level for communication diagnostic in 4-digits hexadecimal.
0 to 10
•
This is the corrected ADC (10-bit) value before communications with the RF Tag were
executed.
Power level
Contains the power level for communication diagnostic in 4-digits hexadecimal.
0 to 10
•
This parameters contains the overall value of the send and receive power levels
calculated with the following formula.
(Send power level + Receive power level)/2
Tag ID data
Contains the Tag ID data of the recognized RF Tag for communication diagnostic in 16-
digits hexadecimal.
•
The value is 0000000000000000 hex (fixed) when the communications result shows an
RF Tag missing error.
