I'm sorry for bumping an old thread...

Can someone tell me more about Texas Instruments TIRIS 4C contents?



For exsample we have ___ 7E 39 32 ED 09 00 00 00 00 D2 46 7E 00 00 ___ readed from TIRIS 4C RFID.

Byte 1 is START_BYTE.
7E means that it is READ_ONLY.
FE means that it is READ_WRITE.

Bytes 2-5 is key in TIRIS format.

Bytes 6-9 is ??????? (always zero?)

Bytes 10-11 is DATA_BCC (CRC-CCITT (XModem) checksum algorithm for 2-9 bytes)

Byte 12 is STOP_BYTE??????? (copy of Byte 1?)

Bytes 13-14 is ???????



Maybe somebody knows what is Bytes 6-14 means?

Thanks!

I think this is not exactly CRC-CCITT (XModem), CRC-CCITT(Kermit) would be correct
