Epson C82314 - Manual (Page 9)

INSTALLING THE INTERFACE CARD
Install the coax interface card in the same way as any Epson optional interface.
This procedure is explained in detail for the individual Epson printers in either an
appendix or the section on Using Printer Options in the user’s manual that comes
with the printer. Please follow the instructions carefully to install the coax interface
card. Secure the interface with the thumb screws. Take precautions to protect the
interface card from static discharge by touching a grounded surface immediately
before installing.
The mini-Centronics connector on the coax interface card can be used for
automatic alternate host (PC) sharing by using the parallel printer share cable
included in the box with the interface.
The interface card is supplied with default setup selections stored in its nonvolatile
memory. These default selections will suffice for most user requirements. Refer
to Appendix A for a listing of the user definable setup selections and custom
features.
EXECUTING A SELF-TEST
Verify proper installation of the coax interface card by performing an interface card
self-test. The self-test also prints out the current setup selections.
1. Before testing the interface card, perform a test of the printer to confirm
that it is functional. Refer to instructions in the printer’s User’s Guide. Do
not proceed unless the printer is operational.
2. To test the coax interface, disconnect the coax and mini-Centronics
connectors from the interface and turn the printer on. After the printer is
ready, press the top (PA1) button on the interface and hold it for more
than two seconds. Release the button and the self test results are printed
as well as a listing of the setup selections.
3. The printer prints out the self-test page if the interface is installed
properly. See the self test printout example, Appendix C.
4. If nothing prints, the interface is not installed properly. A separate test of
the interface may be performed by disconnecting the coax and mini-
Centronics connectors and turning on the printer. If the LED displays red
and then goes out, it indicates successful completion of the self tests. If
the red LED remains on, the self tests found a problem with the interface.
