Transponders
4.2.2.2 Configuration
The Configuration Byte is represented by the first 8 bits of Page 3 of the transponder memory.
Configuration Byte:
Configuration Byte / Bit 6:
Bit= ‘0’: Page 3 is read/write.
Bit= ‘1’: Page 3 can only be read. This process is irreversible !
ATTENTION: Do not set Bit 6 of the Configuration Byte to ‘1’ before having written the
final data into Page 3 (including the Configuration Byte and Password TAG) of the
transponder.
Configuration Byte / Bit 7:
Bit= ‘0’: Pages 1 and 2 are read/write.
Bit= ‘1’: Pages 1 and 2 are locked against writing. This process is irreversible !
ATTENTION: Do not set Bit 7 of the Configuration Byte to ‘1’ before having written the
final data into Pages 1 and 2 of the transponder.
