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. l IEEE-488 interfaces offer standardized connections, trouble-free operation, and the ability to connect computers, printers, and other devices on the same line so that they may share data freely. l Third-party interfaces, such as Coax and Twinax, allow Epson printers to function as local IBM printers without the addition of any other circuitry or components. l Serial interfaces are required if your computer is not equipped 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. 5-44 Using the Printer Options
