2 1. Functions 1.1. Security Functions 96 Bytes can be configured as read-only. Redundant data transfer by data inversion between reader and transponder. Coding of data-current during read and write procedures of the coded area. (size of the pseudo - random generator 2 48 ) copy protection by Password (length of Password: 32 Bit). 16 Byte can be configured as read-only Halt Command "halt" switches-off the data transmission of the transponder. After this command the transponder must be put out of the reader range, otherwise a new data transmission is impossible. Command "halt" makes it possible to communicate with several transponder of type ID DTx.C, which are within reading range at the same time. Therefore, switch-off the finished transponder (by command "halt") and select the next one. H e-ID.doc-ID Page 2 of 8 FEIG ELECTRONIC GmbH

3 2. working modes 2.1. Password- / Secret-Mode The transponder ID DTx.C can work in the password mode or secret mode. Both modes are alternatively configurable where the Secret mode is supported only by readers with a specific crypto processor password mode Before the first access onto the transponder the reader must login with the valid password. The login state is maintained as long as the transponder is in the range of a reader. The password mode offers safety against unauthorized reading and varying the data on the transponder secret mode (crypto function) Data stream is encoded in the secret mode between reader and transponder. A secret encryption algorithm is used for data stream coding. Before first data transfer in the secret mode the reader has to authenticate it self by the transponder. According to authentication, the access to Secret data is free. The secret mode offers safety against monitoring data transfer and unauthorised reading and varying the data on the transponder.

4 2.2. ID CTx.A Emulation This mode allows the emulation of read-only transponders like the type ID CTx.A. For this purpose, the serial number of the ID CTx.A must be programmed into the address D0 and D1 (64 bits) of the ID DTx.C according to the following scheme. Adr.: D007 D006 D005 D004 D003 D002 D001 D000 D017 Data: D016 D015 D014 D013 D012 S00 S01 S02 S03 PR0 D011 D010 D027 D026 D025 S10 S11 S12 S13 PR1 D024 D023 D022 D021 D020 S20 S21 S22 S23 PR2 D037 D036 D035 D034 D033 S30 S31 S32 S33 PR3 D032 D031 D030 D107 D106 S40 S41 S42 S43 PR4 D105 D104 D103 D102 D101 S50 S51 S52 S53 PR5 D100 D117 D116 D115 D114 S60 S61 S62 S63 PR6 D113 D112 D111 D110 D127 S70 S71 S72 S73 PR7 D126 D125 D124 D123 D122 S80 S81 S82 S83 PR8 D121 D120 D137 D136 D135 S90 S91 S92 S93 PR9 D134 D133 D132 D131 D130 PC0 PC1 PC2 PC3 0 address: Series-No data bit.: row parity (even): column parity (even): D n n n S n n PR n PC n Bit Byte Block row column row column Note: If ID CTx.A emulation is configured, OBID standard reader reads this transponder as a transponder of the model ID CTx.A. If you want to use it in ID DTx.C-Mode you have to use the reader command [0x1B]: ID DTx.C select. H e-ID.doc-ID Page 4 of 8 FEIG ELECTRONIC GmbH

5 3. memory model The memory is subdivide into areas with access size of 4 Byte. Numbering system of the data in a data block: Byte: Bit: Address-Layout: The User-Memory (address D0 - D3 resp. S0 - S3) is able for using as Data or one ID-Number. Address Contents Description Note - S-No. Serial-No (4 Byte) read-only D0 / S0 D1 / S1 D2 / S2 D3 / S3 Data public/secret User-Memory: Data ID-Number S-No. for ID CTx.A Emulation read/write read-only configurable secret configurable C0 Config see C0 read/write secret configurable C1 - " - Key 32 / Password read-only configurable C2 - " - Key 16 read/write-log 3 configurable Notes: During the writing of data on a transponder, it must be ensured that the transponder stays complete in the antenna field for the whole time. Changes in Config Data (C0 - C2) takes effect after the transponder had leave the antenna field 3 Data are read an write protected FEIG ELECTRONIC GmbH Page 5 of 8 FEIG ELECTRONIC GmbH

6 3.1. serial number The serial number is the one time programmed, unique number of each transponders with a length of 4 Byte. 3.2.User Memory: address ID-Number / D0 - D3 / S0 - S3 The 16 Byte User-Memory could be used alternative as: ID-Number free-definable, copy and check-sum secured authorisation number, e. g. for access control and time processing systems. By changing the transponder configuration the memory area can be classified as read-only, or moved to secret Data: D0 - D3 (public) User memory "D" is a free definable read- / writeable memory which can be addressed in 4 byte data blocks. By changing the transponder configuration the memory can be classified as read-only, or moved to secret area "S" Data: S0 - S3 (secret) User Memory "S" is a read- / writeable memory for use with crypto systems. It can be addressed in 4 Byte data blocks. The coded data can only be received with a special reader. This reader must be equipped with "Crypto" -processor Configurations and Coding Data: "C" In this memory area the configuration and coding data "C" and the code words for (use with datacurrent coded systems) of the code carrier are stored.

7 C0: Config / PW24 The Config address C0 defines the working modes of the transponder and password "PW24" for the Secret mode. C0: Byte 0 Config Bit Default 0 = Manchester Code 1 = Biphase Code (only for special mode) 0 0 = special mode I (1) 0 1 = ID CTx.A emulation (1) 1 0 = special mode II (1) 1 1 = ID DTx.C standard mode 0 = password mode 1 = secret mode see note (2) 0 = read/write 1 = read-only 0 = read/write 1 = read-only 0 = read/write 1 = read-only 0 = read/write 1 = C1 read/write-log (4) C2 read-only (password mode) C2 read/write-log (4) (secret mode) address: D2 - D3 address: D0 - D1 address: C0 1 = irreversible! (3) Address: C1 - C2 1 = irreversible! Note: (1) If you want to use it in ID DTx.C standard mode you have to use the reader command [0x1B]: ID DTx.C select. (2) The secret mode should only be activated if a reader with crypto function is available. Otherwise, the transponder becomes useless by activating this mode! (3) Bit 6 could only switched one time from 0 to 1. After this address C0 read-only irreversible. (4) Data are read and write protected. If you want to use secret mode, set Bit 6 to 1.

8 C1: Password / Key32 Address C1 has a double function: 1. password-mode: password 32 Bit password, for reader login, before the reader can read ore write data addresses D0 to D3 and C0 to C2. 2. Secret-Mode: Key32 32 Bit key for Authentifikation of the reader on the transponder The 48 bits key for the secret mode put together for itself from Key32 and Key16 (see C2). C1: Byte address C1 0x4D 0x49 0x4B 0x52 Default C2: Key16 Address C2 includes the second part of the 48 Bit key for secret mode.
