Setting the Serial Interface Parameters
(Only for MFC 6550MC/7550MC)
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 set correctly at the factory for Apple Macintosh computers, so you
do not have to change the setting. You may skip this section. If you change parameters
for the RS-232C serial interface and then switch back to RS-422A for Apple Macintosh
computers, be sure to restore the parameters to the factory setting.
• Set the RS-232C parameters to match your IBM compatible 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 setting serial interface parameters, see
the user’s guide for your computer or software.
