Appendix F
Choosing and Setting Up Optional Interfaces
This appendix contains information on Epson interfaces compatible
with EX printers, instructions on choosing the right interface for a
particular job, and instructions for installing internally mounted
interface boards.
Compatible Interfaces
You can use a number of optional interfaces that supplement the EX's
built-in parallel and serial interfaces and the standard 8K data buffer.
These fall into three main categories:
l
IEEE-488 and other special interfaces, which allow connection to
computers with other interface requirements (the Apple interface is
installed in the computer rather than the printer)
l
Buffer interfaces, which provide a larger data buffer to release the
computer for other tasks when printing large amounts of text
l
Serial interfaces providing a wide range of baud rates and other
additional features not available with the standard interface.
The following Epson interfaces are compatible with EX printers. Note
that some of these are no longer available, and that others are not
available in all countries.

If you are using an optional internal interface, set DIP switches 2-5
and 2-6 OFF and do not connect anything to the parallel interface.
