Types of Errors
■ Fatal Operation Errors
If a CPU error or internal memory error occurs, the RUN/RST indicator will go OFF and the RUN output
will turn OFF. If an internal memory error occurs, the COM indicator will also light red.
If an antenna power supply voltage error occurs, the RUN/RST indicator will light green. The RUN
output will not turn OFF.
■ Non-fatal Operation Errors
If an error occurs in communications between the ID Controller and host device or in communications
between a Read/Write Head and Data Carrier, the error code will be displayed on the monitor display.
(Assuming the ID Controller is in Error Code Display Mode.) Up to 30 error records will be saved in the
error log in the ID Controller and can be read using commands from the host device.
