Character Output
Characters are output in the ASCll format as follows:
• When read successfully
Header + character count + code quality + reading characters + FCS + footer + delimiters
• When not read successfully
Header + error code + error characters + FCS + footer + delimiters
Item
Header
Character count
Code quality
Reading character
Error code

2D Code
What is specified for the Header is output. (None may be specified.)
None is output for PLC link.
This is output only when "Character count output" is specified.
Only the reading characters are counted as part of the character count, and if "Output range specify" is
specified, the character count of only that range is output.
For example, if no character is present in the output range, such as when the read character count is 1
and the output range is 2 to 3, 0 will be output.
If "Reading character output" is not specified, 0 will be output.
If kanji characters are included in the reading characters, one kanji character is counted as 1. (This is
different from byte count.)
The output can be switched between 2 bytes and 4 bytes. 0 is added to the left digit if the character
count is less than the byte count (Example: 0010 for 10). "--" is output if the character count in 2-byte
output reaches 100 or more.
This is output only when the "Code quality output" is specified.
The output format is "CxxxFxxxExxx". C represents the contrast, while F and E represent the focus
and the cell recognition rate, respectively. xxx represents each value (0 to 100), and 0 is added to the
left digit if the value is less than 3 digits (Example: 005 for 5).
This is output only if "Reading character output" is specified.
If "Output range specify" is specified, only the characters of that range are output.
For example, if no character is present in the output range, such as when the read character count is 1
and the output range is 2 to 3, no character will be output.
This is output only when "Error code output" is specified.
This is output only when "Error character output" is specified.
This is output only when "FCS" is set to "Available".
The value obtained through an XOR in unit of bytes is output.
The applicable range includes the character count, code quality, reading characters, error codes and
error characters. 0 will be output if nothing that can be output is present in the applicable range.
None is output for PLC link.
What is specified for the Footer is output.
None is output for PLC link.
The delimiters specified in the system data are added only for serial communication non-procedure
output.
