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 MCS is disabled, printer will write the data to tag first then read EPC/TID when <IP0> command is received. If
MCS is enabled, printer reads the TID first then writes the data to tag.
3. If MCS is enabled but fails to read TID, EPC will not be written and it will print as invalid tag.
4. 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.
5. 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.
6. 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.
7. If the printer is powered off, all log data will be lost.
8. When <RU>,00 is set, the whole log buffer will be cleared.
9. If EPC/TID read is not successful, space (0x20) will be returned instead of EPC/TID reply.
10. No log is recorded when EPC code write is specified without print data.
