In the basic setting, all data is output in the form of ASCII characters. Depending on
the data format, this is either a decimal number or in hexadecimal form. In binary
mode, all data is transferred without conversion into ASCII characters. The distinction
between decimal and hexadecimal numbers does not apply. Binary mode is not per-
missible in data format 10, the basic setting. The code is always sent in the form of
ASCII characters.
In
Data Format 10
the first 12 bits (A01h = 1010 0000 0001b) are transmitted as a
hexadecimal number. The next 16 bits (1C3Eh = 0001 1100 0011 1110b) are convert-
ed into a decimal number (1C3Eh =7230d). The code is NOT preceded by a read
head number. Therefore, the use of “X” as the read head number is only of use when
only one read head is connected. Thus, in this example, the following character string
is transmitted:
There is no provision for the
binary mode
in data format 10.
In
Data Format 28
, the first 12 bits (A01h = 1010 0000 0001b) and the next 16 bits
(1C3Eh = 0001 1100 0011 1110b) are converted separately into decimal numbers
(A01h = 2561d and 1C3Eh =7230d). The code is preceded by the read head number,
followed by a space. The character string transmitted is as follows:
Data format
Description
10
This format is active when the control interface unit is switched on
and after transmission of a reset command (RST). The 64 bits of a
code carrier are read, but only 28 bits of data are output. The read
head number is not output. The first 12 bits are transmitted in
hexadecimal notation and the next 16 bits in decimal. All informa-
tion is transmitted in ASCII format: binary mode is not permissible.
If binary mode is selected, an error message is output.
28
The 64 bits of a code carrier are read, but only 28 bits of data are
output as a decimal number. There is no decimal conversion in
binary mode. The code is preceded by the number of the read
head, followed by a space.
