If Multiple Read Message is enabled and a third label belonging to the Code 128 symbology is
decoded, the Multiple Read string will be transmitted instead. If the Multiple Read Message is dis-
abled, the third code label is ignored and only the first two bar codes in the order that they are decoded
will be transmitted.
For advanced formatting, if the Send All Multiple Read Labels parameter is enabled, then all three
labels are sent in the output message; the multiple read label is separated by its own Multiple Read
Label Separator String which should be different from the Data Packet Separator (DPS).
