7.4 Structure of the data base

1 Byte for Attribute (# = no attribute, ‘A’ ... ‘Z’) - transmitted as 1 ASCII-

character

6 Byte for Date/clock in BCD-Format - transmitted as 12 ASCII- characters

1 Byte for Code length (1 ... 16) - transmitted as 1 ASCII- character '0' .. '9',

'A' .. 'F'

The code length is encoded as follows: Value of the ASCII-character =

hex character describing (length – 1).

Example: length =16; length - 1 =15; hex character = 0xF; ASCII-

character = 'F' = CHR(0x46).

8 Byte for the Code (up to 16 nibbles, starting left ) - transmitted as 16 ASCII-

characters

1 Byte for Type of transponder - transmitted as 1 ASCII- character

0 = no known transponder

1 = ISO-FDX

2 = ASK 64Bit

3 = Trovan

4 = Datamars

5 = Destron

6 = ISO-Hdx

7 = Hitag 1/S

8 = Hitag 2

9 = Pontech

A = PSK 2

B = PSK 1

C = PSK 2

D = BDE FDX

E = BDE HDX

F = ISO 14443A 4 Byte

G = ISO 14443A 7 Byte

H = ISO 15693

U = EM 4305

14 Byte for Text (up to 14ASCII’s in the range 0x20 ... 0x7F) - transmitted as

14 ASCII- character
