Multi-line code reading

To specify multi-line code reading, specify “&” followed by the codes to be read. Up to three

rows can be specified.

[Syntax]

“&, code in 1

row, code in 2

row, [code in 3

row]”

Multi-line code reading is independent of single-row code reading.

[Ex.] Reading universal product code EAN-8 and EAN-13 (2 rows):

RdType = "&,A:B,A:A"

[Ex.] Reading 1 row of universal product code EAN-8 and 2 rows of Code 39:

RdType = "A:B,&,M,M"

A 2D code and multi-line code can be specified simultaneously.

[Ex.] Reading a QR code and 3 rows of code 39:

RdType = "Q,&,M,M,M "

When performing multi-line code reading, the read order can be specified using the first two

characters (start/stop in the case of Codabar).

[Ex.] Reading 3 rows of ITF (with character specification) in the following sequence: code

beginning with “12,” code with CD beginning with “21” of 6 – 10 digits in length, and code

beginning with “23” of 12 digits in length:

RdType = "&,I:;12,I:6-10C;21,I:12;23"

It is also possible to specify one character.

[Ex.] Reading a universal product code EAN and ITF (with character specification) in the

following order: EAN beginning with “49”, ITF of 6 – 10 digits in length beginning with “2”.:

RdType = "&,A:A49,I:6-10;2"

Data is output in the order in which the code is specified.

[Ex.] Data is to be output in the sequence of EAN-8 beginning with “12” - EAN-8 beginning

with “21.”

RdType = "&,A:B12,A:B21"

Note, however, that if same character and same number of digits is specified, the output

order will be unpredictable.

[Ex.] Reading 2 rows of ITF, both beginning with “49” and with a length of 6 digits:

RdType = "&,I:6;49,I:6;49"
