Setting the DIP Switches
The DIP switches on the Equity I+ are set to provide your system
with information about itself. Each time you turn on your system, it checks
the DIP switch settings to determine the keyboard type, coprocessor status,
memory size, monitor type, number of floppy disk drives, and the typo of
interfaces being used. The DIP switches are located underneath the cover on
the front of your main unit, below the disk drives, as shown in Figure 1-11.

DIP switches
Your Epson dealer should have set these switches for you. However, read
this section to be sure the settings match your system configuration. If you
upgrade your computer later (by adding a hard disk drive for example) you
may need to alter the DIP switch settings.
Note: Set the DIP switches only while your computer is off. Software pro-
grams check the settings each time you turn on the system, so do not
change the settings while a program is running.
The Equity I+ has two sets of DIP switches; set 1 contains eight switches
which control the computer’s internal operations, and set 2 contains four
switches which control the parallel and serial ports. A label inside the DIP
switch cover show; the functions of each DIP switch and the factory settings.
See Figure 1-12.
