[Description] • Sets the error correction level for PDF417.
• When m = 48, the error correction level is set by the “Level Setting” and the “Ratio
Setting” is canceled. The number of error correction codewords are as follows:
n Function Number of error correction codewords
48 Select error correction level 0 2
49 Select error correction level 1 4
50 Select error correction level 2 8
51 Select error correction level 3 16
52 Select error correction level 4 32
53 Select error correction level 5 64
54 Select error correction level 6 128
55 Select error correction level 7 256
56 Select error correction level 8 512
• When m = 49, the error correction level is set by the “Ratio Setting” to the level
indicated by the number for encoded data, and the “Level Setting” is canceled.
The rate is set to [n × 10%]. The error correction levels in the following table are
determined by the calculation [Data codeword × n × 0.1 = (A)] (fractions of 0.5 and
over are rounded up, and others are truncated.)
Result (A) Use the error correction level Number of error correction codeword
0 to 3 Error correction level 1 4
4 to 10 Error correction level 2 8
11 to 20 Error correction level 3 16
21 to 45 Error correction level 4 32
46 to 100 Error correction level 5 64
101 to 200 Error correction level 6 128
201 to 400 Error correction level 7 256
401 or more Error correction level 8 512
