1.1 Overview

The Standard Multiport Async Solutions

The standard C104P/C168P multiport boards offer 4/8 serial ports for

connecting terminals, modems, printers, data acquisition equipment and any

other serial devices to the PC/AT/Pentium and its compatible systems.

The C104P/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 board is also available in PCI bus.

Please contact MOXA dealer/distributor or Web site for more details.

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

Introductio l l Chapter 1

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 C104P/C168P

board under Windows NT/95 are recommended to adopt quick installation

described in Chapter 2. Other users please see Chapter 3 for installation details.

Because the board 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.

Operating System Support

C104P/C168P is operational under most popular operating systems such as

Windows 95, SCO UNIX/XENIX/OpenServer, DOS, Linux, QNX, FreeBSD,

PICK OS, IMS Multiuser DOS, etc. However, MOXA device drivers for

Windows NT, Windows 95, Linux, SCO UNIX/OpenServer, UNIX SVR4.2,

DOS and Windows 3.x are provided for better installation, configuration and

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

UNIX,DOS and Windows 3.x 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.

Chapter 1 l l Introduction

MOXA Serial Comm Tool

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

communication library under Windows NT/95 (PComm) and Windows 3.x/DOS

(API-232). Users can use this library to produce 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.
