Section 6
Functions
Communication diagnostic is disabled in the default settings. To use communication diagnostic, you must enable it in
advance.
Refer to RF Tag Communications View in Section 8 Web Browser Interface for the setting procedure for communication
diagnostic.
p.196
Use the results of communication diagnostic as a guideline.
An indication of a stable communication (green) does not necessarily mean that communications are normal.
Yellow, which indicates an unstable communication, does not necessarily mean that communications are not possible. It
merely means that there is little leeway in communications.
If you want to ensure more stable communications, we recommend that you use the Reader/Writer so that stable
communications (green) are indicated.
The communication time is approximately 200 ms longer when enabling Communication Diagnostic function.
