Make sure to enter the value "1" in the "Recognize double read" input box.
The acquisition interval must be sufficiently long for the 1D/2D codes in the image to be
read. The interval must be identical on all slave and master devices.

Output of the synchronized read result by the master reader

Output via the TCP interface
The master device synchronizes the results of the slave devices and outputs the synchronized
result via the TCP interface. The result string of the slave device that read the 1D/2D code first
is output. For this purpose, the master device compares the string between "\03" and "\04" of
the read 1D/2D codes. The entire result string is output, whereby the "\02", "\03" and "\04"
texts are first removed.
