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 multidr op half-duplex are available 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 of software 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 by lighting 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 the operation performance, and lower the failure rate of the board. Full range of I/O addresses and IRQ numbers are available. In addition, with on-boar d

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 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-ir q.exe, which read and write the on-board EEPROM for configuration information through the

CAP (Configur ation Access Por t) addr ess. The CAP address is the only channel via

1-2

Industio CI-134 Series User’s Manual

Introduction

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

the fir st por t' s base I/O addr ess.

The CAP jumper, J P1, is designed in case of 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. 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

Ser ies boar d under Windows NT and 95/98 are recommended to adopt quick

installation described in chapter 2, “Hardware Installation”.

Operating System Support

The family is 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 dr iver s 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.

Note !

If the default settings above ar e what you desir ed and good for the system without conflicts, you may simply install the boar d in the system and go dir ectly to the next chapter , “Softwar e

Installation”. Other wise, follow the instr uctions below.

2. After you set all the jumpers and switches, you should do either the nor mal

har dwar e installation (detailed in the later section, “Hardware Installation with

IO-IRQ Utility”) or the quick har dwar e installation (detailed right in the next section, “Quick Hardware Installation”). The latter is provided to facilitate the hardware installation, only under the circumstances that: l l l

Industio CI-134 Series board is allowed to install in a system.

Windows NT and 95/98 are the only operating systems supported.

CAP J umper J P1 is shor t and I/O address 0xA700 must be free.

Quick Hardware Installation

To fully utilize the superior feature of flexible hardware configuration design of the

Industio CI-134 Series, a quick and easy method of installation is designed, which absolutely saves you from hardware configuration effort, i.e., installation

WITHOUT r unning configur ation pr ogr am: Io-ir q.exe. Simply always shor t the

2-2

Industio CI-134 Series User’s Manual

Hardware Installation

CAP jumper J P1. The software and hardware configuration will be completed at the same time while doing the software configuration, detailed in the next chapter. Of course, the method is valid only under the previously described circumstances.

Besides, the speed range will be set to fr om 50 to 921.6K bps by default, which is called High Speed Spectr um and detailed in section "Hardware Installation with

IO-IRQ Utility".

How to Do Quick Hardware Installation

1. Shor t the jumper J P1 on the upper-left corner of the board.

2. Plug the board in PC with the desired system installed (Windows NT or 95/98), which is powered off in advance.

3. Do software (driver) installation, detailed in the next chapter.

This is to specify the desired I/O address, IRQ and INT Vector in the software configuration panel, no matter what hardware settings are on the board. The software configuration program will automatically update the hardware settings.

After this, users already complete the whole installation.

4. Shutdown the system (Windows NT or 95/98).

5. Do power off and then on (or Reset) the PC. (Please cold star t.)

6. Restart System (Windows NT or 95/98).

It is very important to keep the JP1 always short in this case. Without running the hardware configuration program, Io-irq.exe under DOS prompt, the software configuration program will automatically update the hardware settings of the board while updating the software settings. This saves the trouble doing hardware configuration. However, remember to cold star t the system ever y time the

configur ation changed.

Industio CI-134 Series User’s Manual

Hardware Installation with IO-IRQ Utility

This section is for those who can not use quick hardware installation: l Install two or more

Industio CI-134 Series boards in a system.

l

Fail to install, due to the I/O address 0xA700 is not available or has conflict in the system.

l Use operating systems other than Windows NT and 95/98.

Before proceeding to the softwar e (dr iver ) installation, detailed in the next chapter,

“Software Installation”, do har dwar e configur ation to setup the I/O and IRQ with

“Io-ir q.exe”, detailed in the next section.

Remember to keep the hardware settings in mind for the software installation.

Because the ASIC-designed

Industio CI-134 Series has no switch and no jumper for manually configuring the I/O address, IRQ, INT Vector, etc. of the boards, you must run the software utility, Io-ir q.exe, in the driver diskette under DOS system to change the hardware configuration.

1. Choose a PC that has DOS system inside.

2. Power off the PC.

3. Make sure no hardware conflict and plug the board in a free 16-bit slot of the PC,

one boar d at a time with J P1 open.

+

If you are installing multiple boards, insert one board at a time and configure it using the Io-irq program before inserting the next board.

This is to prevent conflict between two boards with same default hardware settings.

The

Industio CI-134 Series has the following default (factory) settings,

I/O address: 0x180 (1st port), 0x188 (2nd port), 0x190 (Port 3), 0x198

(Port 4)

IRQ: 10

INT Vector: 0x1C0

Configuration Access Port (CAP): 0x180

4. Power on the PC and enter into DOS system.

5. Run the utility “Io-ir q.exe” contained in the driver diskette to set up I/O address,

IRQ and INT vector of the board. Please refer to the next section, “IO-IRQ Utility and Hardware Configuration” for more details. Or follow the on-line help to configure the

Industio CI-134 Series board.

After completing the hardware configuration, the board is ready for use under operating systems, such as Windows NT, 95/98, 3.x, DOS, etc.

IO-IRQ Utility and Hardware Configuration

Note that the CAP address, e.g. 0x180, is identical to the fir st por t' s I/O addr ess except in one case that the JP1 jumper is installed before powering on the PC. In this case, the CAP address will be forced to 0xA700. The CAP address must be typed correctly. With the correct CAP address, the utility can find the configuration stored in the on-boar d EEPROM and display it on the configuration panel. The CAP address is the only channel via which the configuration utility Io-irq.exe can access the board.

1. Run the utility “Io-ir q.exe” contained in the driver diskette to set up I/O address,

IRQ and INT vector of the board. Select “Smar tio/Industio ISA Family” and press ENTER in the following dialog box.

Industio CI-134 Series User’s Manual

The followings are fields for configuration.

Port Index

Indicate the port index for each port.

I/O address

Enter the base I/O address for each port, either sequentially or not. Avoid to conflicting with any other devices.

IRQ

Speed

Enter the IRQ, 2, 3, 4, 5, 7, 10, 11, 12 or 15, for each port, independently or not.

This field specifies the use of nor mal or high speed capability.

Normal speed ranges from 50 bps to 115.2 Kbps. High speed ranges from 50 bps to 921.6 Kbps.

Industio CI-134 Series supported both normal and high speed spectra.

Note that, currently, port that uses MOXA Windows NT and

95/98 dr iver will run at the displayed speed. To be clear, when

Industio CI-134 Series board is configured as High Speed

Spectr um, any port driven by the Moxa-pr ovided Windows

NT and 95/98 dr iver will display the exact working speed. For example, the displayed speed 38.4 Kbps is equal to the working speed 38.4 Kbps.

However, if the port is driven by NON Moxa-pr ovided dr iver , such as standar d ser ial dr iver , or Moxa drivers other than

Windows NT and 95/98, such as DOS and Windows 3.x, the real working speed is equal to 8 times of the displayed speed.

For example, a port, if set to Normal Speed Spectrum with 38.4

Kbps, will work at 38.4 Kbps for sure; while a port, if set to High

RS-485 Programming

If you intend to do RS-485 communication with

Industio CI-134 Series, please follow the RS-485 programming guide below and also refer to the chapter, “Connection

Cable and Cable Wir ing”, for more RS-485 operation details.

The

Industio CI-134 Series supports only 2-wire half-duplex RS-485

communication. Data+/- pins are served for both data transmitting and receiving, depending on the mode selected: either Automatic Data Direction Control or By RTS mode.

Automatic Data Direction Control Mode (Recommended)

Automatic Data Dir ection Contr ol scheme is the best solutions for RS-485 applications. The mode switch for the port should be set to ON position, to be able to use Automatic Data Direction Control Mode.

Under this mode, no extra code is required to control the data transferring (data transmitting and receiving), which is automatically managed with the intelligent hardware mechanism. That is, RS-485 pr ogr amming in this mode is just as simple

as RS-232/RS-422 pr ogr amming.

By RTS Mode (For back-compatibility)

If the mode switch for the port is set to OFF position, By RTS Mode is used. The port is ready for transmitting data if RTS signal is asser ted and ready for receiving data if RTS signal is not asser ted.

RTS scheme is a traditional way and suitable for most system, including Windows

NT, Windows 95/98 and DOS, or even UNIX, that permits RTS control from application programs. This mode should be compatible with most of the alreadymade RS-485 applications.

How to transmit and receive data for Windows NT, 95/98 & DOS

We recommend you to configure

Industio CI-134 Series ports as follows in order to acquire precise timing control in RS-485 2-wire transmission.

4-10

Industio CI-134 Series User’s Manual

Serial Programming Tools

There are 2 solutions to control RS-485 2-wire transmission.

Solution 1

The following model is common in RS-485 2-wire transmission.

sio_SetWr iteTimeouts(por t, 0); /* Set sio_wr ite() into block mode if for

Windows NT and Windows 95/98 */ sio_RTS(por t, 1); /* Tur n on RTS signal. The RS-485 por t is r eady for tr ansmitting data. */ sio_wr ite(por t, buff, 10); sio_RTS(por t, 0);

/* Wr ite 10 byte char acter s in " buff" .

The function blocks until last char acter tr ansmitted */

/* Tur n off RTS signal. The RS-485 sio_r ead(por t, buff, 10); por t is r eady for r eceiving data. */

/* Read 10 bytes */

Solution 2

There is a dedicated RS-485 function in

PComm or API-232 library. It integrates the above functions of solution 1 regarding sending data as one.

sio_putb_x(por t, buff, tick ); /* 1. Tur n on RTS and r eady for tr ansmitting data.

2. Send data.

3. Wait for tick time.

4. Tur n off RTS and r eady for r eceiving data. */

For more information on these functions, please refer to

Impedance Matching and Termination Resistors

For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which in turn will contribute communication errors. The solution to this problem is to establish the same impedance at the line ends as in the line itself by terminating them with resistors.

Industio CI-134 already installs the resistors on board for your convenience, indicated as follows. The value of the termination resistor should equal the characteristic impedance of the transmission line. Resistors should be added near the receiving side.

Troubleshooting

Common

Industio CI-134 Series problems and possible solutions are listed below. If you still have problems, contact your dealer or Moxa for help. Or use the “Pr oblem

Repor t For m” at the end of this manual to report problems to your dealer at once for faster technical support.

General Troubleshooting

1. The MOXA dr iver , while installing the dr iver , cannot detect the MOXA boar d.

Hardware causes and solutions:

a. The board is not installed or missing (absent). Please install it.

b. The board is not properly plugged in the system. If that is the case, re-install the board and make sure that it fits well in a 32-bit slot this time. Sometimes the slot for plugging the board is bad. In this case, try other slots until you find a good one.

2. The MOXA boar d and dr iver ar e activated but cannot tr ansfer

(tr ansmit/r eceive) data.

Hardware Causes and Solutions:

a. Check for wrong cable wiring. Refer to the “Connection Cable and Cable

Wiring” chapter for precise pin outs of the connector type you are using.

b. The cable or the board is defective. You may use other ports, cables or boards to verify. In addition, the

PComm “Diagnostic” utility for Windows NT and

Windows 95/98 is good for testing MOXA boards and port conditions. If

Diagnostic reports error, replace the faulty components.

Industio CI-134 Series User’s Manual

6-1

Software Causes and Solutions:

a. For RS-422 mode,

Industio CI-134 Series checks the line status (CTS) before it sends data out if the RTS/CTS flow control feature is set to “Enable” in the configuration or application program. Please refer to the “Connection Cable and Cable Wiring” chapter for proper wiring.

b. Perhaps the application controlling the board is not correctly written according to the corresponding API of the operating system. To verify, please run an existing and known good application or the provided utilities by Moxa.

For example, under Windows NT and Windows 95/98,

Pcomm “Terminal emulator” or “HyperTerminal” utilities are good for testing the COM ports.

3. Why the DOS utility IQ-IRQ can not access

Industio CI-134 to configure?

There are several reasons that may lead to this trouble: a. The user forgets or does not know the Configuration Access Port (CAP) of the board. See next problem 4 for how to solve this problem.

b. The CAP of the board conflicts with other add-on boards’ I/O address. Please change other add-on boards’ I/O address to avoid the conflict.

c. The

Industio CI-134 board is not plugged in a right or good slot. Please plug the board in a good 16-bit ISA slot.

d. The

Industio CI-134 board may malfunction. Please return for repair.

If any existing board has the same I/O address as 0x180, the default CAP address, or the 1st port's I/O address, you must try to avoid the conflict by doing either one the following.

a. Install a jumper (short) at position JP1 on the upper-left corner of the board.

This will force the CAP address to 0xA700.

b. Change or disable the existing board's I/O address.

4. What to do if user for gets or does not know the Configur ation Access Por t

(CAP) addr ess of

Industio CI-134?

The

Industio CI-134 multiport boards are designed without jumper or switch, so the configuration is completed only by DOS utility Io-irq.exe.

To configure the board, you need to know the board’s Configuration Access Port

(CAP) address. Because the CAP address is the only channel, via which the Ioirq.exe can access to the board.
