1 Introduction

Overview

The Standard Multiport Async Solutions

The standard C168P 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.

The Smartio C168P 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 C168 board is also available in PCI bus. Please contact MOXA

dealer/distributor or MOXA Web site for more details.

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

reads and writes 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 C168P 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

C168P User’s Manual 1-3

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, etc. However, MOXA device drivers for Windows NT, Windows 95/98,

Linux and DOS are provided for easier installation, configuration and better

performance. In this manual, chapters for MOXA Windows NT,Windows 95/98

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 C168P is 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
