3-2 Example 2: Multiple-parameter setting by scanning a QR code barcode
User can customize a QR code to set multiple parameters. The scanner can set multiple parameters by
scanning this single QR code barcode.
1. The data format of the QR code barcode is as following.
% Parameter set 1 % Parameter set 2 % Parameter set N %
<Option barcode index><D/H><Alpha. entries>
···
Note that:

<Option barcode index> means the corresponding 4 digits of Option barcode.

<D/H> means “D” or “H” character. D means that the type of alphanumeric entry is decimal; and H
means that the type of alphanumeric entry is hexadecimal.

<Alpha. entries> is a character string with various length of 2, 4, or other values.
Example: Set 0401->03 (decimal); 8002->0D0A (hexadecimal); 8202->01 (decimal). The customized
QR code barcode contents and symbol are as following.
%0401D03%8002H0D0A%8202D01%
2. Notes of making QR code barcode
The model is chosen as M2. Other requirements, e.g. ECC level, Start mode, etc, are not specified.
Other notes

The contents of a QR code barcode can include several same <Option barcode index> associated
with same or different <Alpha. entries>. In the case of with different <Alpha. entries>, the latest
<Alpha. entries> is the valid one.

If any one of the parameter settings is invalid, the total setting is failed. The invalid setting can be
caused by one of the following problems: invalid <Option barcode index>, invalid type of <D/H>,
invalid type, length or value range of <Alpha. entries>, etc.
