Multi-line code reading

To specify multi-line code reading, specify "&" followed by the code to be read.

Up to three lines can be set.

[Syntax]

"&, 1

line code, 2

line code[, 3

line code]"

Multi-line code specifications are independent from read code specifications read in a single line.

[Ex.] Read two lines of universal product codes EAN-8 and EAN-13.

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

[Ex.] Read one line of universal product code EAN-8 and two lines of Code 39.

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

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

[Ex.] Read a QR code and three lines of Code 39.

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

With multi-line code specification, by specifying the first two characters (start/stop character for

Codabar), it is possible to specify the read order.

[Ex.] Read three rows of ITF (with character specification) in the order "code beginning

with "12"", "6 to 10 digit code with check digit beginning with "21", "12 digit code

beginning with "23"".

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

It is also possible to specify a single character.

[Ex.] Read universal product codes EAN and ITF (with character specification) in the

order "EAN beginning with "49"", "6 to 10 digit ITF beginning with "2"".

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

Data is output in the order in which codes are specified.

[Ex.] Output in the order "EAN-8 beginning with "12", "EAN-8 beginning with "21"".

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

However, if the code type and character specification are the same, and the same

number of characters is also specified, the output order will be arbitrary.

[Ex.] Specify two rows of ITF with 6 digits beginning with "49".

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