Interface Boards

You can use optional interface boards to supplement your printer’s built-in serial and parallel interfaces. If youdon’t know whether you need an optionalkterfac,e or if you want to know more about interfaces, contact your Epson dealer,

Choosing an interface

Optional interface boards can be divided into three main categories:

IEEE-488 interfaces that provide standardized connections, trouble-free operation, and the ability to connect computers, printers, and other devices on the same line so that they can share data freely.

Coax and twinax interfaces that connect directly to the printer and communicate with qn IBM minicomputer or mainframe via coax or twinax protoco1. These interfaces allow you to use Epson printers as local IBM printers without adding any other circuitry or components.

Serial interfaces, which are required only if you need an interface that conforms to the Current Loop standard instead of RS-232C or that provides X-on$#Gff data communications protocol.
