Communications Diagnostics

Outline
This function diagnoses the communications leeway whenever the Reader/Writer communicates
with an RF Tag, displays the results on an operation indicator, and reports the results to the host
device.
With a UHF RFID system, the communications performance is affected by various environmental
factors (e.g., installation distance between Reader/Writer and RF Tag, installation objects, and radio
wave interference from other wireless devices). You can use the communications diagnostics to
check the leeway in communications and achieve more stable RFID system operation.
The communications diagnostics information reports three main results: stable communications,
unstable communications, and communications errors.
The NORM/ERR operation indicators light green for a stable communication, yellow for an unstable
communication, and red for a communications error.
