PCI Express Boards Introduction

Overview

Moxa’s new PCI Express Multiport Serial Boards are designed for POS and ATM applications and for use by

industrial automation system manufacturers and system integrators. The boards are compatible with all

popular operating systems, and each of them supports data rates of up to 921.6 kbps and provides full modem

control signals, ensuring compatibility with a wide range of serial peripherals. In addition, all models work with

PCI Express x1, allowing the boards to be installed in any available PCI Express slot (including x1, x2, x4, x8,

x16, x32).

PCI Express Solution

The boards comply with PCI Express Spec. 1.1. The ports’ transmission parameters are configured after the

boards are installed. The PCI BIOS automatically assigns the IRQ and I/O addresses. For this reason, you must

plug the boards into the computer before installing the drivers. For more information about PCI Express, refer

to the “Technical Reference” appendix.

ESD Protection

The PCI Express boards come with15 kV ESD protection built in to prevent damage to the boards from lightning

or high potential voltage. The surge protection feature makes the PCI Express boards suitable for industrial,

factory-type applications, and for use with applications that are subject to severe weather conditions.

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

RS-485 uses differential data transmission over two wires to transmit data from one station to another, and

allows multiple transmitters and receivers to be used on the same data line. RS-485 uses half-duplex

transmission, which means that transmission and reception share the same data channels. For this reason,

only one transmitter can be active at any given time.

Moxa’s serial boards have a built-in circuitry to switch transmitters on and off automatically. We call this form

of switching ADDC® (Automatic Data Direction Control). ADDC® is much easier to implement than the

traditional handshaking method that uses the RTS signal.

Operating System Support

The PCI Express boards are compatible with all major industrial platforms, including Windows, Windows CE,

DOS, Linux, and SCO. Moxa device drivers are provided for smoother installation, configuration, and

performance.

4. Configuring Intelligent RS-485

In this chapter, we describe the use of the “Auto-Tuning” and “Diagnosis” tools, supported by Moxa's Intelligent

RS-485 boards, to tune your RS-485 network. The Auto-Tuning tool tests your RS-485 network and then

configures certain Moxa boards (CP-118E-A-I, CP-138E-A-I, CP-134EL-A-I, and CP-116E-A) automatically. The

Diagnosis tool can tell you how to manually configure other Moxa boards, as well as non-Moxa boards. We use

the CP-134EL-A board to demonstrate how to use the Intelligent RS-485 tools for Windows 7/8/8.1.

The basic procedure you should follow is illustrated in the following workflow diagram:

Moxa PComm

PComm, a professional serial communication tool for PCs, is a software package that runs under Windows

NT95/98/2000/XP/2003/Vista/2008/7(x86 and x64). PComm provides:

• A powerful serial communication library that simplifies serial programming tasks for most popular

programming languages. The serial communication library is useful for developing applications for data

communications, remote access, data acquisition, and industrial control for Windows

NT95/98/2000/XP/2003/Vista/2008/7(x86 and x64), and is a simpler programming solution compared to

the more complex Windows Win32 COMM API.

• Useful utilities such as diagnostics, monitor, and terminal emulator.

• Illustrative sample programs.

• Comprehensive online documentation.

Installing PComm

To install PComm, run \Setup.exe from the Documentation and Software CD. Note that the PComm

diagnostics and monitor utilities are for Moxa boards only. To use these utilities, you must have a Moxa board

and the appropriate Windows (NT/95/98/2000/XP/2003/Vista/2008/7(x86 and x64) device driver installed in

your system. See the “Software Installation” chapter for instructions on how to install the drivers.

After installing PComm, click Start, select Program Files, and then the PComm Lite group to select from the

list of utilities and documents.

PComm Programming Library

The serial communication library helps you develop serial communications programs for any COM port that

complies with the Microsoft Win32 API. This library facilitates the implementation of multiprocess, multithread

serial communication programs, and greatly reduces the time required to develop applications.

For a complete description of the library functions and sample programs for Visual C++, Visual Basic, and

Delphi, check the help file and the sample programs in the PComm directory.

Utilities

In this section, we provide brief descriptions of each utility. For more information about these utilities, read the

online help from the Documentation and Software CD.

Diagnostics (for Moxa boards only)

This convenient diagnostics program, which only works with Moxa boards and ports, provides internal and

external testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD, etc. The diagnostics program allows

the user to check both the hardware and software functions.

PCI Express Boards Serial Programming Tools

To run the diagnostics program, click Start  Program  PComm Lite  Diagnostic. A typical test report

for a Moxa board is as follows:

Monitor (for Moxa boards for Windows

2000/XP/2003/Vista/2008/7(x86 and x64)

This useful port status monitoring program allows you to monitor data transmission of selected Moxa COM

ports. The program monitors data transmission/reception throughput and communication line status, with data

updated and displayed on the screen at regular time intervals. Click a specific port to see a graph of the current

communication parameters and status of that port.

To run the Monitor program, click Start Program  PComm Lite  Monitor.

PCI Express Boards Serial Programming Tools

Terminal Emulator

Use Terminal Emulator to connect to your PC’s serial ports to check if data is being transmitted correctly.

Terminal Emulator features multi-windows and supports VT100 and ANSI terminal types. You can transfer data

interactively, send patterns periodically, and transfer files using ASCII, XMODEM, YMODEM, ZMODEM, and

KERMIT protocols.

To run Terminal Emulator, click Start  Program  PComm Lite  Terminal Emulator.

RS-485 Programming

If you are using your CP-118EL Series board for RS-485 applications, in addition to reading this section, you

should also refer to the “Connection Cables and Cable Wiring” chapter for more details about using RS-485.

The CP-118EL Series supports 2-wire half-duplex RS-485 and 4-wire full-duplex RS-485 communication. Ports

configured for 2-wire RS-485 use the Data+ and Data- pins for both transmitting and receiving data. Moxa’s

own ADDC™ (Automatic Data Direction Control) technology is used to switch between transmission and

reception.

ADDC™

ADDC™ is the best method for switching between transmission and reception when using 2-wire RS-485.

When using ADDC™, an additional code is not required to switch between data transmission and reception,

since the board’s built-in intelligent hardware mechanism automatically manages the switching mechanism.

RS-485 programming using ADDC™ mode is just as simple and straightforward as RS-232 or RS-422

programming.

CP-118EL-A

The CP-118EL-A board has a female SCSI VHDCI68 connector on the board, with various connection options

available for connecting from the board to your serial devices. In this chapter, we provide pin assignments for

the board side connector, as well as pin assignments for device side connectors for the different connection

options.

The CP-118EL-A board supports RS-232, RS-422, 4-wire RS-485, and 2-wire RS-485. Note that the RS-422

standard uses a balanced voltage digital interface to allow 9600 bps communication over cables of up to 4000

feet in length. You can connect ten receivers to one driver for broadcasting systems. The RS-485 standard is an

enhanced version of the RS-422 balanced line standard. It allows multiple drivers and receivers to work on a

multidrop network. A maximum of 32 drivers and 32 receivers can be set up on a multidrop network. The

CP-118EL-A board supports both 2-wire half-duplex and 4-wire full-duplex RS-485 communications. In 2-wire

RS-485, Data+/- pins are used for both data transmitting and receiving.

8. Troubleshooting

In this chapter, we discuss the common PCI Express Series problems and possible solutions. If you still have

problems after reading this chapter, contact your dealer or Moxa for help, or use the Problem Report Form at

the end of this manual to report problems to your dealer.

1. The Moxa PCI Express board cannot be detected by the Moxa driver while installing the driver.

Hardware causes and solutions:

a. Express slot. It is also possible that a slot has malfunctioned. In this case, try other slots until you find

one that works.

b. The motherboard does not have an available IRQ for the PCI Express board. In this case, enter the BIOS

and make sure there is an available IRQ under PCI/PnP settings.

2. The Moxa PCI Express board and driver are activated but cannot transfer (transmit/receive)

data.

Hardware Causes and Solutions:

a. Make sure the cable wiring is connected correctly. Refer to the “Pin Assignments” chapter for correct

cable connections.

b. The cable or the board could be defective. Try other ports, cables, or boards to verify this, or use the

PComm Diagnostic utility to test the Moxa board and port conditions. If the Diagnostic program reports

an error, replace the faulty components.

Software Causes and Solutions:

a. PCI Express Series boards will check the line status (CTS) before transmitting data if the RTS/CTS flow

control feature is set to Enable in the configuration or application program. Refer to the “Connection

Cables and Cable Wiring” chapter for proper wiring diagrams; then, check the line status of the

suspected port, using the diagnostics LED indicators on the mini tester.

b. The board control application may not be written correctly according to the corresponding API of the

operating system. To check this problem, run another application that you know is correct, or use the

utilities provided by Moxa (such as PComm Terminal emulator or HyperTerminal that runs under

Windows platform).
