e Maximum number of digits
The maximum number of digits varies according to the ECC type or format ID.
Since each Kanji character uses 2 bytes, the maximum number of digits for it
becomes half of the following values.
ECC0 ECC50 ECC80 ECC100 ECC140
Format ID 1 500 457 402 300 144
Format ID 2 452 333 293 218 105
Format ID 3 394 291 256 190 91
Format ID 4 413 305 268 200 96
Format ID 5 310 228 201 150 72
Format ID 6 271 200 176 131 63
Numeric Alphanumeric 8 bit
ECC200 2000 2000 1556

f Connection setting
The connection setting is used to comprise data with a set of two-dimensional codes
when the data cannot be expressed with a two-dimensional code. When three two-
dimensional codes are used to comprise data, identification information of 1/3, 2/3,
and 3/3 is inserted into each two-dimensional code. The ID number is programmed
to include a proper combination of two-dimensional codes when one label contains
plural connecting symbols. For example, when there are two kinds of data
containing identification information for 1/2 and 2/2 in the same label, combination of
two-dimensional codes is unclear. By adding the ID number, the combination is
made clearer.
