The total length of all data fields plus the number of the character count bytes (= the number of the
fields) should be 255 bytes or less.
When you transfer five 50-digit (50-byte) fields, for example, the total length of all data fields is 250
(50 x 5) bytes and the number of the character count bytes is 5. Accordingly, the total is 255, so you
can transfer the file.
