Setting 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 setting. 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.

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 by moving up (on) or down (off) the selectors of the dual in-line package (DIP) switch.
