Details of Errors
Fatal Errors
If a CPU error or internal memory error occurs, the RUN/RST indicator will go out and RUN outputs will
turn OFF. For internal memory errors, the COMM indicator will light red.
For Antenna supply voltage errors, the RUN/RST indicator will light green. RUN outputs will not turn
OFF.
Nonfatal Errors
If an error occurs in communications between the ID Controller and host device or between the
Antenna and a Tag, an error code will be displayed on the monitor display (error code display mode).
Details of up to 30 errors can be stored in memory and can be read with a command from the host
device.
