1 Introduction

Overview

Smartio - The Smart Multiport Async Solutions

The term Smartio stands for smart multiport serial I/O solution. The Smartio C168

Series multiport boards offer 8 serial ports for connecting terminals, modems,

printers, data acquisition equipment and any other serial devices to the PC/AT and

its compatible systems. With the well-designed and fine-tuned device driver, the

Smartio boards make full use of the 32 byte Tx/Rx FIFO and on-chip H/W flow

control, so that they can transfer data without data loss even at high speed such as

921.6 Kbps, which offers a reliable and high performance solution for serial

multiport communications.

The Smartio C168 Series is equipped with custom-designed ASIC chip which

replaces lots of conventional ICs and reduces the board to half-size. The whole

family supports 16 bit architecture. Full range of I/O addresses and IRQs are

available. In addition, with on-board EEPROM for storing the configuration data,

the family is designed without jumper or switch. These features make each port on

the board truly independent to any other port and thus compatible with most existing

multiport boards.

The Smartio C168 Series is also available in PCI bus. Please contact MOXA

dealer/distributor or MOXA Web site for more details.

New : set I/O address Traditional : set switch and

and IRQ via software and jumper manually for

Utility. I/O address and IRQ.

Instead of using traditional jumper or switch for IRQ and I/O address settings,

hardware configuration of each port is easily set by DOS utility, Io-irq.exe, which

read and write the on-board EEPROM for configuration information through the

CAP (Configuration Access Port) address. The CAP address is the only channel

via which the configuration utility Io-irq.exe can access the board, which is identical

to the first port's base I/O address.

The only jumper, JP1, is designed in case that users forget the CAP address.

Normally JP1 is left open. When JP1 is short, the CAP address is forced to a fixed

I/O address, 0xA700. However, to adopt quick installation (described later), it is a

must to keep JP1 always short.

Quick Installation

To ease the hardware configuration, users who install only one Smartio C168

Series board under Windows NT/95/98 are recommended to adopt quick

installation described in Chapter 2.

Because the family is so flexible in hardware configuration that they are compatible

virtually with all kinds of other manufacturer's multiport boards using 16450 or

16550 UART.

Introduction

Smartio C168H/HS User’s Manual 1-3

Surge Protection

To prevent the boards from damage caused by lighting or high potential voltage,

surge protection technology is introduced in some model to protect the board.

Operating System Support

The family is operational under most popular operating systems such as Windows

NT, Windows 95/98, SCO UNIX/XENIX/OpenServer, DOS, Linux, QNX,

FreeBSD, UNIX SVR4.2, However, MOXA device drivers for Windows NT,

Windows 95/98, Linux, SCO UNIX/OpenServer, UNIX SVR4.2 and DOS are

provided for easier installation, configuration and better performance. In this

manual, chapters for MOXA Windows NT,Windows 95/98,UNIX and DOS

device drivers are included. For other compatible systems not mentioned, please

refer to the respective operating system’s manual for how to install and configure

the standard driver.

MOXA Serial Comm Tools

For easy application development, MOXA provides an easy-use serial

communication library under Windows NT/95/98 (PComm) and DOS (API-232).

Users can use this library to develop your own applications using Microsoft C,

Turbo C, Assembly, QuickBASIC, Turbo Pascal, Clipper, Visual Basic, Visual C++,

Borland Delphi, etc. Utilities, such as diagnostic and monitor, are included for

diagnosing the board/port or monitoring the communication status.

Wide Applications

The Smartio C168 Series are suitable for many applications. Here are a few:

lInternet/Intranet Connection

lRemote Access Application

lMulti-user Application

lIndustrial Automation

lOffice Automation

lTelecommunication

lPC-based (vending) Machine or Kiosk System

lPoint-of-Sale (POS) System
