How to set the Serial Interface Parameters
 Note
This section is only for printer models which have had the serial interface installed.
!
Caution
Be sure to set the parameters to match your computer as follows:
• 
Never change the RS-422A parameters for Apple Macintosh computers.  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 change the serial
settings for your PC 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.
• 
Do not alter the dual in - line package (DIP) switch settings when the printer
power is on.
If necessary, set the serial interface parameters as follow:



  1.
Make sure that the printer is in the off-line state.



  2.
Set the serial interface parameters you require by referring to Table 1 below and by
moving up (on) or down (off) the selectors of the dual in-line package (DIP) switch.
The default settings for both RS-422A and RS-232C modes are all switches set to
OFF (down).
