Operational Example 2 When the number of symbol readings reaches "04H" ("4") with multiple reads.
First Read
z
Symbol A and C were successfully read, Symbol B and D were not.
Because the number of symbol readings has not reached the maximum allowed, reading will continue.
Second Read
z
Because Symbol A and C were successfully read on the first try, they will not undergo second read processing.
Symbol B has again been successfully read. Because Symbol B has been read twice which is equivalent to the Sym-
bol Read Number, Reading will halt and result data will be output.
Reading Results of each symbol will be output in the order they were successfully read.
Outut Result is as follows
Global Symbol A
Prefix Reading Result
Global Symbol B
Prefix Reading Result
Regarding the Order of Output
If you read multiple symbols, note the following points.
Outupt result will output results in the order that they were successfully read.
Reading Success Order depends on various external factors such as image acquisition timing.
