When a communications command is executed, communications diagnostics are performed to diag-
nose how much leeway there is in RF communications.
Monitoring status during operation helps create a more stable Reader/Writer and RF Tag installa-
tion.
*1. If you enable communications diagnostics, the communications time will be longer than when they are dis-
abled.
You can specify the transmission power for read communications and write communications. If you
adjust the transmission power according to the communications distance, you can suppress radio
wave interference and reduce reading non-target RF Tags.
*1. The communications distance is shorter when writing data to an RF Tag in comparison with reading data from
an RF Tag. The difference in the communications distance varies depending on the RF Tag.
