SERIAL INTERFACE BOARD RS100M (For HL-730 series Only)

To connect the printer to a DOS computer with a serial interface or to an Apple Macintosh computer, you need to install the optional serial interface board. When you have installed the serial interface board, you can share the printer between two computers (two IBM compatible PCs or one IBM compatible PC and one Apple Macintosh) using the parallel and serial interfaces at the same time. Automatic interface selection is a standard feature.

✒Note

∙The serial interface board for this printer is optional, but in some countries the serial interface board may have been installed by either the factory or dealer.

∙The serial interface for Apple Macintosh (RS-422A) will only print at 300 dpi.

The serial interface board is installed onto the main controller board inside the printer. For the details about installation, see the instruction guide which was provided with the serial interface board.

Selecting the RS-422A (Apple) or RS-232C (IBM) Serial Interface

✒Note

This section is only for printer models which have had the serial interface installed.

!Caution

Be sure to select the serial interface type to match your computer as follows:

∙For Apple Macintosh computers: you should not have to change any settings because the Apple (RS-422A) setting is factory selected (default).

∙For IBM compatible PCs you should move the switch to the IBM (RS- 232C) setting.

∙If you are using an Apple Macintosh on the RS-422A port and an IBM compatible PC on the parallel port, it is not necessary to make any changes to the switch setting.
