Choosing an interface board

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 they can share data freely.

•Coax and twinax interfaces that connect directly to the printer and communicate with an IBM minicomputer or mainframe via coax or twinax protocol. This allows Epson printers to function as local IBM printers without the addition of any other circuitry or components. These interfaces are currently available from manufacturers other than Epson.

•Serial interfaces, which are usually not necessary because the DFX-5000 has a built-in serial interface.

The following Epson interfaces are compatible with the DFX-5000.

Installing an interface board

The following steps explain how to install an optional interface board. Before you install the board, disconnect the printer cable from the printer’s built-in parallel interface. The built-in parallel and an optional interface should not be connected at the same time.

Note: If you install an optional interface board, make sure your printer’s DIP switches are set for parallel interface, even if you are installing a serial interface board.
