Chapter 1Introduction

Welcome to the MOXA CP-132UL Series of industrial 2-port RS-422/485 serial boards for the PCI bus. Moxa’s Universal PCI CP-132UL series meets the new slot standard for expansion boards, and works with both 3.3V and 5V PCI slots. The CP-132UL series offers 2 independent RS-422/485 serial ports for connecting data acquisition equipment and many other serial devices to a PC and compatible systems. It provides a reliable communication link (RS-422/485) over a long distance (up to 4000 ft), and is suitable for industrial environments.

The following topics are covered in this chapter:

Overview

Industio—The Industrial Multiport Async Solution

Moxa Industio products are smart, multiport serial I/O solutions for industrial applications. The CP-132U Series boards, including CP-132UL V2, and CP-132UL-I V2 (the

previous version is CP-132U-I V1), are designed for a 32-bit PCI bus with the Plug and Play and Universal PCI feature. They offer 2 independent RS-422/RS-485 serial ports for

connecting data acquisition equipment and many other serial devices to the PC and its compatible systems. Industio products provide a reliable communication link over a longer distance (up to 4000 ft), and are suitable for industrial environments. Connections with point-to-point full-duplex or multidrop half-duplex are available to meet user’s various needs. Each port can control up to 32 devices in a multidrop environment.

ADDC™ (Automatic Data Direction Control) for RS-485

To make it easier to manage 2-wire RS-485 half-duplex connections, ADDC™ (Automatic Data Direction Control) intelligence is built into each CP-132UL series board, eliminating the need for software interference. This means that Windows applications can manage RS-485 ports, without the need to write extra code for controlling the half-duplex protocol.

With their well-designed and fine-tuned device driver, CP-132UL series boards make full use of the 128 byte Tx/Rx FIFO and on-chip H/W and S/W flow control, so that they can transfer data without loss even at speeds as high as 921.6 Kbps, providing a reliable, high performance solution for serial multiport communications.

Termination Resistors Ready for RS-422/485

Termination Resistors are already installed on the CP-132UL series boards, eliminating the headaches involved in determining the proper impedance for the resistors. For more details, refer to the “Connection Cable and Cable Wiring” chapter.

Surge/Isolation Protection

To prevent boards from being damaged by lightning or high potential voltage, CP132UL Series boards have built-in surge protection. An optical isolation option (2000V), and surge protection option (max. ESD of 16 KV, max. EFT of 2 KV) are also available in this series. Both of these features provide protection when the boards are used in critical or harsh factory-type environments.

CP-132U Series User’s Manual

Introduction

PCI Solution

The board complies with PCI Spec. 2.1 and does not require either switches or jumpers. The hardware configuration for the IRQ and I/O address is automatically assigned by the PCI BIOS. This means that the board MUST be plugged into the computer first before installing the driver software. For more PCI information, refer to the Technical Reference Appendix.

Universal PCI

The 32/64-bit PCI local bus specification specifies both 3.3V and 5V connector types for the PCI hardware. Moxa’s universal PCI card allows the user to plug into both a 3.3V/5V and 32/64-bit slot.

Operating System Support

The CP-132UL series is compatible with most major industrial platforms, including Windows 2000/XP/2003, Windows NT, Windows 95/98/Me, DOS, and Linux. MOXA device drivers are provided for smoother installation, configuration, and performance. In this manual, sections for MOXA Windows 2003, Windows 2000/XP, Windows NT, Windows 95/98, DOS, Linux, and SCO are included.

MOXA Serial Comm Tools

For application development, MOXA provides an easy-to-use serial communication library called PComm that runs under Windows NT/2000/XP/2003 and Windows 95/98. You 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, terminal emulation, or even file transfer.

Broad Applications

The board is suitable for many industrial applications, including the following:

! Multipoint data acquisition ! Factory automation ! Critical industrial control ! Remote serial device control

Hardware Installation

CP-132UL Series boards have four onboard DIP Switches, referred to below as S1-1, S1-2, S2-1, and S2-2, that allow the user to choose one of three serial interfaces—RS-422, RS-485 (2-wire), RS-485 (4-wire)—for each of the two ports. Note that S2-1 and S2-2 select between RS-422 and RS-485, and S1-1 and S1-2 select between 2-wire and 4-wire RS-485 (S1 is only active when S2 is set to ON).

The figures on the following page show you how to use the switches to select one of the three serial interfaces for each of the board’s two ports.

Installing the CP-132UL Series Board

Step 1: Power off the PC.

Warning! To avoid damaging your system and board, make sure your computer is turned off

before installing any board.

Step 2: Remove the PC’s cover.

Step 3: Remove the slot cover bracket if there is one.

Step 4: Plug the CP-132U Series control board firmly into a free 32-bit PCI slot or 64-bit

PCI slot.

Step 5: Fasten the holding screw to fix the control board in place.

Step 6: Replace the system cover.

Step 7: Power on the PC. The BIOS will automatically set the IRQ and I/O address.

Note! Moxa Universal PCI or PCI boards will occupy one unique IRQ and I/O address,

which are assigned automatically by the PCI BIOS.

Step 8: Proceed with the software installation discussed in the next chapter, “Software

Installation.”

4. If there are any special marks, such as a question mark or an exclamation mark in front

of the icons, the installation of the board or the ports was not successful. Examine the Event Log for details.

Port Configuration

After the driver is installed, the MOXA CP-168U Installation dialog box will be displayed, and the system will map the ports automatically.

If one MOXA CP-168U board was installed previously, and another MOXA CP-168U board is added, the system will prompt you to take care of port configuration, which is discussed in this section.

1. Click on a specific port from the CP-168U Series Installation window, and then click

on [Port Setting] to open the Port X dialog box.
