If you are using an optional interface, you may need to match the communications protocol of the printer and the computer so they can communicate properly. Use the information in your optional interface manual or the computer manual to match the computer with the interface.

For the #8143 optional interface board, use the DIP switch settings shown below. These DIP switches are on the interface board, not on the printer.
