Interface Cards

Installing an interface card
Using a serial interface card

You can use optional interface cards to supplement your printer's built-in serial and parallel interfaces. The EPSON interface cards below are compatible with your printer. (Not all of these interfaces are available worldwide.)

Number	Name
C82305/C82306	Serial interface
C82307/C82308	32KB intelligent serial interface
C82312	LocalTalk interface
C82313	32KB IEEE-488 interface
C82314	Coax interface
C82315	Twinax interface
C82345	IEEE-1284 parallel interface
C82434	EpsonNet 10/100 Base Tx Int. Print Server 5

The asterisk (

) is a substitute for the last digit, which varies by country.

If you are not sure whether you need an optional interface or would like to know more about interfaces, contact your EPSON dealer.

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 the SelecType mode 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.

Installing an interface card

Follow the steps below to install an optional interface card.

Note:

If you install an optional interface card, make sure you set the interface you use in the SelecType mode. See Changing the settings in the SelecType mode for details.

Turn off both your printer and your computer. Then remove all power and interface cables from the printer.

Turn the printer so that the rear cover faces you.

Open the rear cover.

* rear cover

Be sure to set any switches and jumpers on the card, as necessary. See the interface card's manual for details. Make sure that you set jumper JG to on, or the card will not work properly. (To set the jumper to on, cover both wires of the terminal with the rectangular jumper plug.)

Use a screwdriver to remove the screws securing the interface shield plate; remove the shield plate.

Slide the interface card into the grooves in the interface slot. Push it in firmly to make sure it connects to the printer's internal socket.

Secure the interface with the screws provided with the card.

Plug the connector cable into the interface card as shown.

Plug the other end of the cable into your computer.

Close the interface cover.

Plug the power cord into your printer and an electrical outlet.

Using a serial interface card

To use a serial interface card (C82305 or C82306), see the sections below to set the correct baud rate, handshake timing, and error handling. For all other data transfer conventions, such as word structure and communications protocol, see your interface card manual.

Selecting a baud rate

You can select from the following baud rates: 300, 600, 1200, 2400, 4800, 9600, and 19200 bps (bits per second). To set the baud rate, see the bit-rate selection table in your interface card manual.

Handshake timing

When the unused area for data in the input buffer drops to 256 bytes, the printer outputs an X-OFF code or sets the DTR flag to 1 (MARK) to indicate that it cannot receive data. When the unused area increases to 512 bytes, the printer outputs an X-ON code or sets the DTR flag to 0 (SPACE) to indicate that it is ready to receive data.

Error handling

When the printer detects a parity error, it prints an asterisk (). The printer ignores all other errors, including framing and overrun errors.
