You can check information on measurements and diagnostics that were performed in RF Tag com-
munications for the last communications command that was executed by the Reader/Writer.
You can check the communications diagnostic information by sending a command from the host
device.
The following table lists the information that you can get in the communications diagnostic informa-
tion.
A/B Communications performance was
reduced because of the influence of metal
around the RF Tag. Remove all metal from around the RF Tag.
* If the recommended RF Tag
(V780-A-JIME-BLI-10) is mounted on a metallic
material, install it on an Attachment
(V780-A-TA-133-10).
A/B Communications performance was
reduced because of the influence of metal
around the Reader/Writer. Remove all metal from around the Reader/Writer.
* Metal behind the Reader/Writer will not influence
performance.
A/B/C/E Communications performance was
reduced due to the influence of reflected
radio waves. Change the position of physical structures or the
Reader/Writer and find the best radio wave environ-
ment.
C Communications performance was
reduced by the influence of radio wave
interference from a wireless device near
the Reader/Writer. Move wireless devices away from the
Reader/Writer.
C Communications performance was
reduced by the influence of interference
from a low-frequency device near the
Reader/Writer. Move low-frequency devices away from the
Reader/Writer.
D The RF Tag is traveling too quickly. Reduce the speed of the RF Tag.
E The RF Tags are too close to each other. Separate the RF Tags farther from each other.
Getting RF Communications Diagnostic Information
Item Description Remarks
Time Indicates the time that the Reader/Writer communi-
cated with the RF Tag.
Command code Indicates the code that identifies the communications
command that was executed.
Communications result
(error code) Indicates the code that identifies the communications
command that was executed.
Diagnostic result Indicates the code that identifies the result of commu-
nications diagnostics.
Communications normal, communications error, insuf-
ficient power to send, insufficient power to receive, too
much noise, insufficient signal-to-noise ratio, insuffi-
cient read data, or excessive read data
Diagnostic details Indicates all diagnostic results detection status as bit
information.
