Specification to record RFID data log
1. For logging RFID data, select "Data To Record" and "Log RFID Data" from "Interfaces"->"RFID" section.
2. If RFID data log(Log RFID Data) is enabled, the buffer (the storage area for 100 logs to store UID) will be saved in
printer's RAM. When the buffer is filled with logs, the new log data will overwrite from the oldest log.
3. 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
4. When RFID data log (LogRFID Data) is disabled, it returns 1 log. It doesn't get cleared after the data is returned with
[DC2] PK.
5. If the printer is powered off, all log data will be lost.
6. When" <RU>,00" is set, the whole log buffer will be cleared.
7. No log is recorded when code write is specified without print data.
[Format of [DC2]PK return data when RFID data log is enabled (normal state)]
