NOTE
1) Termination code
• Robot transmit
When CRLF (carriage return + line feed) is selected:
Transmits data with a CR code (0xDH) and LF code (0xAH) added at the end of a line.
When CR (carriage return) is selected:
Transmits data with a CR code (0xDH) added at the end of a line.
• Robot receive
Receives data by treating entries made up to the CR code as 1 line and ignoring the LF code, regardless of
which termination code is selected.
2) If the "Display language" parameter is set to "JAPANESE" in SYSTEM mode, then set the character length to 8
bits. Katakana letters (Japanese phonetic) cannot be output from the communication port if set to 7 bits.
