Introduction

Overview

Industio - The Industrial Multiport Async Solution

The term Industio stands for smart multiport serial I/O solution for industrial

applications. The Industio CI-134 Series boards,including CI-134, CI-134I and

CI-134IS, are designed for 16-bit ISA/EISA bus. They offer 4 independent RS-

422/RS-485 serial ports. It offers reliable communication link over a longer distance

(4000ft). It is best suitable for industrial environment.

Connections with point-to-point full-duplex or multidrop half-duplexareavailable

to meet your needs. Each port can connect up to 64 devices, such as data acquisition

equipment and many other serial devices, to the PC and its compatible systems in a

multidrop environment.

Automatic Data Direction Control for RS-485

To ease the 2-wire RS-485 half-duplex control, Automatic Data Direction Control

intelligence is built on each Industio CI-134 board. Eliminating the need ofsoftware

interference. Hence, the applications can manage the RS-485 port without extra code

to control the half-duplex protocol.

Termination Resistors Ready for RS-422/RS-485

Termination Resistors are already installed on the Industio CI-134 boards and no

more headaches for finding proper resistors and connecting them for impedance

matching problem. More details are in chapter, “Connection Cable and Cable

Wiring”.

Surge/Isolation Protection

To meet the demand of high reliability in industrial environment and to prevent the

boards from damage caused bylighting or high potential voltage, an optical isolation

option (2KV) and surge block option (2KV) are available. This is critical to harsh

environment such as factory.

ASIC Design, Compact Size

The Industio CI-134 Series is equipped with MOXA customer-designed ASIC chip,

which replaces lots of conventional IC and hence reduces the board to half-size,

increase theoperation performance, and lower the failure rate ofthe board. Full range

of I/O addresses and IRQ numbers 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 anyother

port and thus compatible with most existing non-intelligent boards. Because the

family is so flexible in hardware configuration, it is compatible virtually with all

kinds of other manufacturer's non-intelligent multiport boards using 16550 UART.

CAP Address

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 onlychannel via

Introduction

Industio CI-134 Series User’s Manual 1-3

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

the first port's base I/O address.

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

NormallyJP1 is left open. When JP1 is short, the CAP address is forced to a fixed I/O

address, 0xA700. While doing quick hardware installation, JP1 is required to be

shorted, detailed in chapter, “Hardware Installation”.

Quick Installation

To ease the hardware configuration, users who install only one Industio CI-134

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

installation described in chapter 2, “Hardware Installation”.

Operating System Support

The familyis operational under most popular operating systems such as Windows NT,

Windows 95/98, DOS, SCO UNIX/XENIX/OpenServer, Linux, QNX, FreeBSD, etc.

However, MOXA device drivers for Windows NT, Windows 95/98, DOS and

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

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

Windows 3.x device drivers are described. For those compatible systems not

mentioned, please refer to system’s manual for how to install and configure the

standard driver.

MOXA Serial Comm Tools

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

library under Windows NT, Windows 95/98 (PComm), DOS and Windows 3.x

(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 Data Scope, Monitor, Terminal

Emulator, Diagnostics, etc., are included for debugging or monitoring the

communication status or terminal emulation or even file transferring.
