Specification to record RFID data log
• For logging RFID data, select [Data To Record] and [Log RFID Data] from [Interface] > [RFID]
section.
• If RFID data log (Log RFID Data) is enabled, the 5KB buffer (the storage area for 100 logs to
store both EPC and TID) will be saved in printer's RAM. When the buffer is filled with logs, the
new log will overwrite from the oldest log.
• When RFID data log (Log RFID Data) is enabled, the log data is returned in chronological order
when it receives [DC2] PK. After the log data returns, the buffer is thoroughly cleared.
• When RFID data log (Log RFID Data) is disabled, it returns 1 log. It doesn't get cleared after the
data is returned with [DC2] PK.
• If the printer is powered off, all log data will be lost.
• When <RU>,00 is set, the whole log buffer will be cleared.
• If EPC/TID read is not successful, space (0x20) will be returned instead of EPC/TID reply.
• No log is recorded when EPC code write is specified without print data.
