If you can, change the settings on the computer rather than the interface board because the interface is set up at the factory to give optimum performance in a wide range of conditions. If your dealer has installed the interface for you, he or she should also be able to adjust the computer and interface to achieve a good match.

If you do need to change the settings on the interface yourself, (perhaps in order to use a different computer), the tables below will help you match the computer and interface. The settings given in the table cover the conventions used by the computer and printer as data is transferred. There are other DIP switches and jumpers, but for most purposes you only need change the settings described here. The other settings are described in the manual supplied with the interface.

The three following tables contain all the information you need for the optional interface settings.
