The Interface Boards

A number of optional interfaces are available that supplement the
capabilities of your printer's built-in serial and parallel interfaces.

Choosing an Interface

Optional interfaces can be divided into three main categories which
are described briefly below.
IEEE-488 interfaces offer standardized connections, trouble-free
l
operation, and the ability to connect computers, printers, and
other devices on the same line so that they may share data
freely.
Third-party interfaces, such as Coax and Twinax, allow Epson
l
printers to function as local IBM printers without the addition of
any other circuitry or components.
Serial interfaces are required if your computer is not equipped
l
with a parallel interface or if you need an interface that conforms
to the Current Loop standard instead of RS-232C. These
interfaces also provide some combination of the following
features: X-ON/X-OFF data communication protocol, loopback
self test modes, and data buffers that increase the printer's data
buffering capacity by 8 KB.
If you are unsure whether you need an optional interface or would
like to know more about interfaces, contact your Epson dealer.

Compatible Interfaces

The current interfaces that are compatible with your printer are the
New serial interface (#8143), the Intelligent serial interface (#8148),
the Intelligent IEEE-488 interface (#8165), the Coax interface, and the
Twinax interface. New optional interfaces are introduced from time
to time. Check with your Epson dealer for the most up-to-date list.
