Installing An Interface Card - Epson DFX-9000 Reference Manual

Note:
Your printer has an auto interface mode function that allows you to
connect to more than one interface at a time. See "Changing the
settings in SelecType mode" on page 94 for details.
Coax and twinax interfaces enable the printer to 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.
