CR+LF code
When a computer transmits data to the converter, some computers automatically provide either one or both of the codes CR (carriage return)
and LF (line feed) at the end of a data group. In this case, the same setting is required for data sent from the converter to the computer. Use
Pr.124 PU communication CR/LF selection
for the CR+LF code setting.
