Output Format

The Output Format register shares the same specification among most templates; this paragraph details this common implementation.

For templates that have their own specification for Output Format, it is detailed directly in the template’s chapter.

Register t1: output format

Register 03t1 defines the output format.

This register has 2 different specifications:

  • Numeric output (raw/hexadecimal or decimal) is selected if bit 6 in byte 0 is 0
  • String output (ASCII or UTF8) is selected if bit 6 in byte 0 is 1

Numeric output (raw/hexadecimal or decimal)

For a numeric output, the register has 1 or 2 bytes. If only byte 0 is defined, byte 1 defaults to 00.

Byte Bits Content
0 7 Direction
0 : direct direction (send the data bytes as they are retrieved from the RF card)
1 : reverse direction (swap bytes)
6 Numeric output, must be 0
5 RFU, must be 0
4 Suppress leading zeros
0 : keep all digits
1 : suppress digit 0 on the left
3-0 Format and length
0000 : Decimal, 4 bytes as 10 digits
0001 : Raw/Hexadecimal, 4 bytes
0010 : Raw/Hexadecimal, 8 bytes
0011 : Raw/Hexadecimal, 5 bytes
0100 : Raw/Hexadecimal, 10 bytes
0101 : Raw/Hexadecimal, 7 bytes
0110 : Raw/Hexadecimal, 11 bytes
0111 : RFU
1000 : Raw/Hexadecimal, 16 bytes
1001 : Raw/Hexadecimal, 20 bytes
1010 : Raw/Hexadecimal, 24 bytes
1011 : Raw/Hexadecimal, 32 bytes
1100 : Decimal, 5 bytes as 12 digits
1101 : Decimal, 5 bytes as 13 digits
1110 : Decimal, variable length
1111 : Raw/Hexadecimal, variable length
1 7 RFU, must be 0
6-4 Drop first bits (000 i.e. 0 to 111 i.e. 7)
3-0 Drop first bytes (0000 i.e. 0 to 1111 i.e. 15)

String output (ASCII or UTF8), variable length

For a variable-length string output, the register has 1 or 2 bytes. If only byte 0 is defined, byte 1 defaults to 00.

Byte Bits Content
0 7 Direction
0 : direct direction (send the data bytes as they are retrieved from the RF card)
1 : reverse direction (swap bytes)
6 String output, must be 1
5 RFU, must be 0
4 Variable length string, must be 1
3-0 RFU, must be 0000
1 7-0 Max output length from 01 to FF. Use 00 for ‘no limit’.

String output (ASCII or UTF8), fixed length

For a fixed-length string output, the register has 1 byte only.

Byte Bits Content
0 7 Direction
0 : direct direction (send the data bytes as they are retrieved from the RF card)
1 : reverse direction (swap bytes)
6 String output, must be 1
5 Padding with SPACE char, if too short
0 : padd on the left (before the string)
1 : padd on the right (after the string)
4 Fixed length string, must be 1
3-0 Length
0000 : 16 characters
0001 : 1 character
0010 : 2 characters
0011 : 3 characters
0100 : 4 characters
0101 : 5 characters
0110 : 6 characters
0111 : 7 characters
1000 : 8 characters
1001 : 9 characters
1010 : 10 characters
1011 : 11 characters
1100 : 12 characters
1101 : 13 characters
1110 : 14 characters
1111 : 15 characters
