Error code name Error code Description
Unfixed operation mode error
8001 hex
The control signal was not stable when the Reader/Writer was started. A
record is stored only in the system error log.
User setting error
8002 hex
An error was detected in user configuration memory when the Reader/
Writer was started. A record is stored only in the system error log.
The classification of the setting is given in attached information 1.
0000 0001 hex: Network setting
0000 0002 hex: RF Tag communications setting
0000 0003 hex: Multi-Reader/Writer setting
Multi-Reader/Writer execution
error
8003 hex
A set value was detected when the Reader/Writer was started that
prevents execution of multi-Reader/Writer operation.
The reason for the error is given in attached information 1.
0000 0001 hex: The combination of the Multi-Reader/Writer Mode and
the communications option prevented execution.
0000 0002 hex: This Reader/Writer has the same IP address as the
Slave Reader/Writer.
