The CAT interface requires the availability of the following number formats:

ASCII

BINARY

BCD

Decimal

Hex

ASCII is a standard 8 bit representation of characters and symbols in computing.

Binary is the digital representation of a number as a string of '0' and '1'. The base is 2.

BCD is a binary format for the representation of a decimal number.

Decimal is the common decimal representation of the numbersystem 0....9 to the base of 10.

Hex is a number representation to the base of 16. The hex number set is normally noted as 0...9,A,B,C,D,E,F.

For the CAT operations we also need the following notations for numbers:

# followed by a number is interpreted as a decimal number, not as ASCII-character nor as Hex number!

#$ followed by a number is interpreted as a hex number, not as ASCII-character nor as decimal number!

The following notations apply for the representation of numbers in parameter strings:

Leading blanks in a frequency string noted as f:

'ffffffff' ---------> ' 1234'

Leading '0'or #0 in a frequency string noted as F:

'FFFFFFFF' --------> '00001234'

Leading blanks in a RIT frequency string noted as r:

'rrrr' --------> ' 12'

Leading '0'or #0 in a RIT frequency string noted as R:

'RRRR' --------> '0012'

Leading blanks in a mode byte noted as m:

'mm' ---------> ' 1'

Leading '0'or #0 in a mode byte noted as M:

'MM' ---------> '01'

Leading blanks in a field strength string noted as s:

'sss' ---------> ' 1'

Leading '0'or #0 in a field strength string noted as S:

'SSS' ---------> '001'
