10.7.2 Output of the synchronized read result by the master reader
Output via the TCP interface
The master reader synchronizes the results of the slave readers and outputs the
synchronized result via the TCP interface. The result string of the slave reader that first
reads the 1D/2D code is output. To compare the 1D/2D codes read, the master device
compares the string between "\03" and "\04". The entire result string is output although "\02",
"\03" and "\04" are first removed.
If a slave reader sends the result string "\02Slave01:\03DMC123\04" and read the"DMC123"
code first, the master reader sends the "Slave01:DMC123" string to its TCP partner.
