CHAPTER ONE

Introduction

The 

 

 and the 

 are high-performance expansion

boards for ISA or Micro Channel computers. The SYNC/570 adds two syn-

chronous/asynchronous serial ports while the 

 adds two or four

synchronous/ asynchronous ports. They are designed for applications

requiring cost-effective communications. Each board and connector

package is supplied with all the hardware and software needed for a

complete board installation.

The Hitachi HD64570 Serial Communications Adapter 

 provides a

highly-integrated advanced communications subsystem for the SYNC/570

and the 

 It further maximizes synchronous communications

performance by using protocol-specific features to minimize driver

overhead.

The 

 memory of both the SYNC/570 and the 

 is directly

addressable by both the system and the 

 DMA. Program-initiated DMA

transfers operate at 

 speed independently of other system

activity. This architecture provides low system overhead and high

performance.

The optional OEM software lock ensures that OEM software will operate

only with OEM-supplied boards.

 (and SYNC/570 optionally) includes 

 which is

designed to protect the board and the computer in which it is installed

against damage from data line surges.

Multiple SYNC/570 boards may share a common memory window. Micro

Channel boards may also share a common interrupt request line.

The two ports of the 

 each have a high density DB-15 connector

to connect any device with an EIA-232-D interface to your computer. The

board operates at line speeds from 4800 baud to over
