Data formats DF
The data format can be specified in any command which expects a read code as pe-
sonse. If the data format is not specified, the previously selected format remains ef-
fective. When the format is specified, it must be preceded by a comma in order to
distinguish it from the read head number. At system switch on, format 10 is adopted
and the data output is in ASCII characters. The binary representation can be selected
by an SB command.
In the basic setting, all data is delivered as ASCII characters but depending upon the
data format this takes place in denary or hexadecimal form. In the binary mode all
data is transmitted without conversion into ASCII characters. No distinction is made
between denary and hexadecimal. In data format 10 - the basic setting - the binary
mode is not admissible and the code is always transmitted as ASCII characters.
R1<CR><LF>
The read head 1 reads a code if a code carrier is available. If
no code carrier is available within range of the read head an
error message will be issued.
arx<CR><LF>
If, for example, the read heads 1, 3 and 4 are connected,
they will be activated one by another. When a code carrier
comes within range of the read head it will be read and
transmitted.
Data format
Explanation
10
This format is active following switching on and of the con-
trol interface after sending an RST command. All 64 bits of a
cod carrier are read but only the 28 bits of user data are
returned. A read head number is not returned. The first 12
bits are sent in hexadecimal and remaining 16 bits in
denary. All information is then transferred as ASCII charac-
ters, the binary mode not being admissible. In the event of
the binary mode being selected, an error message will be
returned.
28
All 64 code carrier bits are read but only the 28 user data
bits are returned. In the binary mode no denary conversion
takes place. The code follows the read head number and is
preceded by a space character.
64
A code carrier is read and all 64 bits returned in hexadeci-
mal form.
