Network Card User Manual

INTRODUCTION
The Serial Interface Card C82307 * /C82308 * is an interface
that allows asynchronous serial data communication
between a host computer and an EPSON printer.
This interface card offers the following features:
•
A 32K byte buffer that frees up your computer for
other uses while your printer continues to print
•
Two self-test functions that can help solve interface
problems
•
Data transmission that can be set at either RS-232D,
RS-422A,
or 20-mA Current-Loop levels (RS-232D
has been revised from the former RS-232C. Set the
signal levels for RS-232D the same as for RS-232C.)
•
Handshaking protocol using X-on/X-off or DTR flag
control
•
Selectable data word structure that allows you to
choose parity (Odd, Even, None, or Ignore) and
word bit settings (either 7 or 8 bit)
•
Selection of baud-rate settings from 75 to 38,400 BPS
(Data transmission speed is limited to 19,200 BPS
when interface is set to either RS-232D or 20-mA
Current-Loop.)
•
DIP-switch 1 settings that you can change even after
installation
