Chapter 1 Introduction

Moxa’s PCI Express serial boards meet the new slot standard for expansion boards, and work with
any PCI Express slots. The boards have multiple RS-232/422/485 serial ports for connecting data
acquisition equipment and other serial devices to a PC.

This chapter covers the following topics:

PCI Express Board User’s Manual Introduction

1-2

Overview

Moxa’s new PCI Express Multiport Serial Boards, named CP-118EL, CP-168EL, and CP-104EL,
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,
CP-118EL, CP-168EL, and CP-104EL work with PCI Express ×1, allowing the boards to be
installed in any available PCI Express slot (including ×1, ×2, ×4, ×8, ×16, ×32).

PCI Express Solution

The boards comply with PCI Express Spec. 1.1. The serial transmission mode (RS-232, RS-422,
2-wire RS-485, or 4-wire RS-485) for each port is set with onboard switches (CP-118EL has DIP
Switches, CP-168EL and CP-104EL are RS-232 only), but 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 PCI Express information, refer to the “Technical Reference” appendix.

ESD Protection

The PCI Express boards come with built-in 15 KV ESD protection 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

To make 2-wire RS-485 half-duplex connections easier to manage, ADDC™ (Automatic Data
Direction Control) intelligence is built into the CP-118EL board, eliminating the need for software
interference. Windows applications can be set up to manage RS-485 ports without writing
additional code to control the half-duplex protocol.

Operating System Support

The PCI Express boards are compatible with all major industrial platforms, including Windows
2000/XP/2003, DOS, and Linux. Moxa device drivers are provided for smoother installation,
configuration, and performance. In this manual, we provide installation details for Windows
2003/XP, Windows 2000, DOS, Linux, and SCO.

Visit Moxa’s website at www.moxa.com

to download the latest drivers and user’s manuals for all

of Moxa’s products.

Moxa Serial Comm Tool

For application development, Moxa provides an easy-to-use serial communication library called
PComm that runs under Windows NT/95/9 8/20 0 0/ XP/2003. Use this library to develop your own
applications with Visual Basic, Visual C++, Borland Delphi, etc. Utilities, such as Data Scope,
Monitor, Terminal Emulator, and Diagnostics are included to make it easier to debug, monitor
communication status, provide terminal emulation, and transfer files.

CP-118EL has three onboard DIP Switch arrays, each with 8 switches, shown in the table below
and on the listed board (see the above block diagram) as S1, S2, and S3. The switches are used to
select one of four serial interfaces—RS-232, RS-422, 4-wire RS-485, 2-wire RS-485—for each of
the eight ports. Note that S3 selects between RS-232 and RS-422/485, S2 selects between RS- 422
and RS-485, and S1 selects between 2-wire and 4-wire RS-485.

Plugging the Board into an Expansion Slot

Since the BIOS automatically assigns the PCI Express board’s IRQ number and I/O addresses, you
must plug the board into one of the computer’s expansion slots before installing the driver.

Step 1: Power off the PC.

WARNING

To avoid damaging your system and board, make sure you turn off your computer before
installing the board.

Step 2: Remove the PC’s cover.
Step 3: Remove the slot cover bracket if there is one.
Step 4: Use the onboard DIP Switches to set the transmission mode for each port (see the previous

section for details); (CP-118EL only)

Step 5: Plug the PCI Express board firmly into a free PCI Express slot.
Step 6: Fasten the holding screw to fix the control board in place.
Step 7: Replace the PC’s cover.
Step 8: Power on the PC. The BIOS will automatically set the IRQ and I/O address.

NOTE

Each Moxa PCI Express board uses one unique IRQ and I/O address, both of which are assigned
automatically by the PCI BIOS.

Step 9: Proceed with the software installation discussed in the next chapter, “Software

Installation.”

Chapter 3 Software Installation

This chapter gives installation, configuration, and update/removal procedures for the driver for
Windows 2000, Windows 2003/XP/Vista/2008 (32-bit/64-bit), DOS, Linux (32-bit/64-bit), and
SCO, and WinCE 5.0. Before proceeding with the software installation, complete the hardware
installation discussed in the previous chapter, “Hardware Installation.”

Refer to the next chapter, “Serial Programming Tools,” for information about developing your
own serial programming applications. Note that you can install up to 4 PCI Express boards in one
system, provided sufficient I/O address and IRQ number resources are available.

You can download the Windows 2000/XP/2003/Vista/2008, DOS, Linux, and SCO, and WinCE

5.0 drivers from the Moxa website.

Windows Drivers

Moxa provides drivers that allow you to use the following serial board products under Windows
2008/Vista/2003/XP/2000, Windows 98/95, and Windows NT. Windows 95/98/NT do not support
PCI Express drivers.

The overall procedure for
installing the Windows drivers
for the PCI Express boards is
summarized in the flowchart on
the right.

Plug the PCI Express board into an
empty PCI Express slot. See the
Hardware Installation chapter.

Driver already installed?

Install the driver from the
Documentation and Software CD. See
the Installing the Driver for the First
Time subsection for detailed
instructions.

Configure the boards ports. See the
Configuring the Ports subsection for
detailed instructions.

WARNING

If you are installing a PCI Express board on an ASUS A8N Series (AMD CPU) motherboard a n d
the installation process hangs the first time, then restart the PC to reinstall it.

NOTE

The following steps use CP-114EL as an example.

PCI Express Board User’s Manual Software Installation

Windows 2008/Vista (32-bit/64-bit)

In this section, we describe the installation procedure for Windows Vista. The installation
procedure for Windows 2008 is similar.

Windows 2008 and Windows Vista support up to 256 serial ports from COM1 to COM256. In
order to make the best use of Windows 2008/Vista’s multi-process/multi-thread advanced features,
32-bit and 64-bit Windows 2008/Vista device drivers were developed for Moxa multi port boa r ds.
The drivers conform to the Win32 COMM API standard.

Installing the Driver

The following procedure describes how to install the CP-114EL driver for the first time with
Windows Vista. First, make sure that you have already plugged the board or boards into the
system’s PCI Express slot(s).

NOTE

If you have already installed a CP-114EL or other Moxa PCI Express board in your co mputer,
and you are installing additional boards, Windows 2008/Vista will automatically detect and
install the new board(s) the next time you boot up the computer. In this case, proceed directly to
the next section, “Configuring the Ports,” to configure the ports’ serial transmission parameters.

1. After plugging the board into an expansion slot and powering on your PC, Windows Vista will

automatically detect the new board, and the Found New Hardware window will open.

for Windows 2003 is similar.

Windows 2003/XP support up to 256 serial ports, from COM1 to COM256. In order to make the
best use of Windows 2003/XP’s multi-process/multi-thread advanced features, 32-bit and 64-bit
Windows 2003/XP device drivers were devel oped for Moxa multiport boards. The drivers
conform to the Win32 COMM API standard.

Installing the Driver

The following procedure shows how to install the CP-118EL driver for the first time under
Windows XP. First, make sure that you have already plugged the board or boards into the system’s
PCI Express slot(s).

NOTE

If you have already installed a CP-118EL or other Moxa PCI Express board in your co mputer,
and you are installing additional boards, Windows 2003/XP will automatically detect and install
the new board(s) the next time you boot up the computer. In this case, proceed directly to the next
section, “Configuring the Ports,” to configure the ports’ serial transmission parameters.
