There are also system commands, used to input control statements to the system,
such as restart, switch to binary mode, or output the software version number. The
system commands are executed in both normal and binary modes. In the case of the
system commands, no additional parameters are required.
6.1.4 Data formats for the basic fixed code operating mode
For each command, it is possible to specify the data format in which the codes, when
read, are to be transmitted via the serial interface. If the data format is not specified,
the previously selected format will be used. If it is specified, it must be preceded by a
comma to distinguish it from the read head number. When the system is switched on,
data format 10 is set, and the data output is in ASCII character format. Binary repre-
sentation can be selected with the command SB.
Command Description
RST Restart
This command cancels all previously programmed commands and
resets the control interface unit to the basic settings, i.e. with no
active read command and using data format 10. The control interface
unit recognizes the parity setting on the received characters R, S,
and T and adapts accordingly. Since this command enables the con-
trol interface unit to identify the parameters for serial transmission,
the command must be entered either all in upper case or all in lower
case.
SB Set binary mode
All the data read is transmitted one byte at a time, one byte consisting
of 8 data bits. This format is possible only if the serial interface is set
to transmit 8 data bits per byte, and should be used when transmis-
sion speed is a priority.
The command “SB” is valid only if data format 28 has previously been
set via a read command. The RST command is used to exit the
binary mode.
SD Set double sided mode
In this mode, code carriers ICC-50 and ICC-50F are read from the
back, i.e. the side away from that carrying the code. With these code
carriers, the same read distance may be achieved on either side.
Note that in the worst case, the read time may be doubled. The dou-
ble sided mode can be cancelled by transmitting the command RST.
VER Version number
This command is used to request output of the software version num-
ber.
