HITAG 2 Transponders
Product Specification 3.0
July 2006
5.2 Operation Modes and Configuration
With the Configuration Byte the operation mode and the access rights to the memory can be
selected. During Power-Up of the transponder the Configuration Byte is read from the EEPROM
of the transponder.
If you change the configuration, keys or passwords, you have to place the
transponder directly on the antenna (0-distance)! In order to avoid any errors do not
move the transponder during this write process and be sure that you are in a safe
environment without electrical noise.
5.2.1 Modes of Operation
The HT2DC20S20 can be operated in several modes.
Crypto Mode:
Mode for writing or reading the transponder with encrypted data transmission.
Password Mode:
Mode for writing or reading the transponder with plain data transmission.
Public Mode A (Manchester):
Read only mode emulating Philips MIRO transponders resp. µEM H400x transponders.
The 64 bits of the user Pages 4 and 5 are cyclically transmitted to the read/write device.
Public Mode B (Biphase):
Read only mode according to ISO standards 11784 and 11785 for animal identification.
The 128 bits of the user Pages 4 to 7 are cyclically transmitted to the read/write device.
Public Mode C (Biphase):
Read only mode emulating the read operation of the PCF793X (with a slightly different Program
Mode Check).
In the Public Mode C the 128 bits of the user Pages 4 to 7 are cyclically transmitted to the
read/write device.
