INTRODUCTION
EPSON
The Serial Interface C82302* / C82304* is an interface
board that allows asynchronous serial data communication between a host computer and an Epson printer.
This board features:
a 32K byte buffer that frees up your computer for
other uses while your printer continues to print.
32KB
Serial Interface

problems.
signal levels that can be set at either RS232C or 20
mA Current Loop.
handshaking protocol using X-on/X-off or DTR flag
control.
selectable data word structure. This allows you to
choose parity (Odd. Even, or None) and word bit
settings (either 7 or 8 bit).
selection of baud rate settings from 75 to 19,200 BPS.
(Data transmission speed is limited to 1,200 BPS
when the signal level is set to 20 mA Current Loop.)
This optional interface board is intended for use with the
following Epson printers:

(SW1 or SW2) and number. Therefore, the switch in set

disconnecting a circuit. The jumper is on when the
jumper plug covers both wires of the terminal. Jumper
settings can be changed by either attaching or removing
the rectangular jumper plug. If the jumper is to be

Handshaking p r o t o c o l
x-dx-df Protocol
X-on/X* protocol is a system in which the printer
transmits a code to the computer to indicate that it
cannot accept more data, and a second code when it is
once again ready. This protocol can be performed under
either RS232C or 20 mA Current Loop signal levels.
The C82302*/C82304* interface board sends an X-on
<11>H code when it is ready to receive data, and an Xoff <13>H when it is busy. The X-On/X-off Signals may
be transmitted from the TXD ten&al at RM32C signaJ

information
Figure 3. X-on/x-off timing
Note
X-on/X-off protocol cannot be performed when the
buffer operation is disabled. But the DTR flag protocol
is still possible.
After the X-on flag has been set, data can be accepted up
to the maximum capacity of the buffer.

Transmit timing of X-off signal
The X-off signal is transmitted when the vacant area
for bytes in the buffer drops to 512 or 16 bytes
(selectable with DIP switch 2-6).

Data can be sent to the printer even after the X-Off
signal is transmitted as long as sufficient room for
data remains in the buffer. However, if the transmitted data exceeds the vacant area in the buffer, it will
be discarded. X-off character will be transmitted
again when the remaining buffer capacity is actually
0 bytes. At the same time, BS code <08>H and “/”
character <2F> H will be sent to the printer.

DTR protocol
This interface board also provides for DTR handshaking
protocol using either RS-232C or Current Loop signal
levels
Under this system, when the printer is turned on the
DTR enters the SPACE state, meaning that data entry is
enabled. When the rate of data reception is greater than
that of printing, the buffer gradually fills up. once the
vacant area for transmitted bytes drops to 512 or 1
bytes, the DTR sets the status flag to prohibit further.

20) under RS-232C signal levels, and through the TTYTXD (pin No. 17) under Current Loop levels.

About data entry
To accommodate data entry, the C82302*/C82304*

cannot be accepted and is discarded. To prevent such
