5.5 Setting the Communication Conditions
When your plotter is connected via an RS-232C cable to a computer, be sure to set identical communication
conditions in the software and OS communication settings for the data transfer rate (baud rate), data length,
and parity. This section describes the settings on the plotter side. For setting instructions for the software
and OS side, consult the respective user's manuals. Three groups of communication settings can be
completed, allowing you to switch to a different group of settings in a single operation.
