Automatic Interface Selection
This printer has an Automatic Interface Selection feature. When the
printer receives data from the computer, it automatically selects the
interface that is appropriate.
When you use the parallel interface, you can turn the high-speed and
bi-directional communications ON or OFF by using the control panel
Menu buttons to go to the INTERFACE menu. For more information,
see Chapter 3. Since the Automatic Interface Selection feature has
been set at the factory to ON, simply connect the interface cable to
the printer.
When you use the serial interface, you need to have the same
communications settings on both the printer and the computer. Since
the Automatic Interface Selection feature has been factory set, you
may be able to simply connect the interface cable to the printer if your
computer has the settings listed below.
If a network board (Brother NC-4100h) has been installed, use the
control panel to select NETWORK.
When necessary, use the control panel in the INTERFACE menu to
select the interface or the serial communications parameters
manually. For more information, see Chapter 3. For the computer
settings, see the manual for the computer or software you are using.
