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
