Epson C82346 - Manual (Page 18)

Connecting the network cable
Once the board is installed in your printer, you must attach the
network cable to the interface. The Ethernet Card can accept
either a 10BASE-T or 10BASE network cable.
The Ethernet Card is an intelligent interface that can detect
which kind of cable is attached; you do not need to make any
hardware or software settings to specify the cable type.
However, you must not attach more than one cable at a time.
Attach the network cable to the appropriate connector on the
interface, as shown in the diagram.

Setting up the printer
Some EPSON printers require you to use the printer’s control
panel or DIP switches to select the interface you plan to use.
The method of making control panel settings on EPSON
printers may be called SelecType or default-setting mode. See
your printer manual for instructions on making the necessary
interface settings.
