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
