    DIP switch settings 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 or small screwdriver. Caution All changes of DIP switch and jumper settings should be made with the printer power turned off.
