Caution
Be sure to set the parameters to match your computer as follows:
Never change the RS-422A parameters for Apple Macintosh
computers. Because the RS-422A parameters have been correctly set
at the factory for Apple Macintosh computers, you do not need to
change the settings. You may skip this section. If you change
parameters for the RS-232C serial interface and you switch back to
RS-422A for Apple Macintosh computers, be sure to restore the
parameters to the factory settings.
Set the RS-232C parameters to match your computer. You can set
serial settings in several different places, within your DOS
application, within the Windows Printer Icon (for Windows
application software only), or within your AUTOEXEC.BAT file
using MODE commands. For information on serial interface
parameters, see the user’s guide of your computer or software.
