SETTING THE CONDITIONS DIP switch settings
The C82303* interface board has a set of DIP (Dual In-line
Package) switches, and 6 jumpers. This switch and jumpers
are used for selecting various interface operations.
Before you install the C82303* interface, you may need to
adjust some of the settings. When making DIP switch setting
changes, it is best to use a pointed device, such as a ball-point
pen or small screwdriver.

All changes of DIP switch and jumper settings should be made

About DIP switches
A set of DIP switches on the C82303* is labelled SW1. SW1
contains a number of individual toggle type switches that can
be set either on or off. The individual switches are referred to
by set (SW1) and number. Therefore, the switch in set SW1
marked by the small number 3 is called DIP switch 1-3.
