Chapter 1 Introduction
Moxa’s CP-134U Universal PCI serial board meets the new slot standard for expansion boards,
and works with both 3.3V and 5V PCI slots. The board has eight independent RS-232/422/485
serial ports for connecting data acquisition equipment and other serial devices to a PC.
The following topics are covered in this chapter:

CP-134U Series User’s Manual Introduction
Overview
Smartio—The Smart Multiport Async Solution
CP-134U is one of the newest members of Moxa’s well-known Smartio series of multiport serial
boards, in which Smartio stands for Smart Multiport serial I/O solution. The 8-port
RS-232/422/485 CP-134U board is designed for the plug-and-play 32-bit PCI bus, and is an
economical solution for connecting terminals, modems, printers, scanners, cash registers, bar code
readers, keypads, numeric displays, electronic scales, data acquisition equipment, and many other
serial devices for the PC and compatible systems. The Smartio device driver makes full use of the
128 byte Tx/Rx FIFO and on-chip H/W and S/W flow control. Your applications will be capable of
transmitting data without loss at speeds as high as 921.6 Kbps, providing a reliable, high
performance solution for multiport serial communications.
PCI Solution
The CP-134U series board complies with PCI Spec. 2.1. 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, but the
ports’ transmission parameters are configured after the board is installed. The IRQ and I/O
addresses are assigned automatically by the PCI BIOS. For this reason, the board MUST be
plugged into the computer before installing the driver. For more PCI information, refer to the
“Technical Reference” appendix.
Surge Protection
The CP-134U series board comes with built-in 15 KV ESD surge protection to prevent damage to
the board from lightning or high potential voltage. The surge protection feature makes the
CP-134U board 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-134U series board, eliminating the need for
software interference. This means that 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 CP-134U series board is compatible with all 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, we give
installation details for Windows 2003/XP, Windows 2000, Windows NT, Windows 95/98, 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.
Universal PCI
The 32/64-bit PCI local bus specification requires that PCI hardware be compatible with both 3.3V
and 5V connector types. Moxa’s universal PCI cards can be plugged into 3.3V or 5V, and 32-bit or
64-bit slots.
Moxa Serial Comm Tool
For application development, Moxa provides an easy-to-use serial communication library called
PComm that runs under Windows NT/2000/XP/2003/95/98. 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-134U Series User’s Manual Hardware Installation
The CP-134U series has two 30-pin jumpers and two sets of four DIP Switches on the board that
allow the user to set the serial interface for each of the board’s four ports. Ports 1 and 2 can be set
to RS-232, RS-422, RS-485 (2-wire), or RS-485 (4-wire). Ports 3 and 4 can be set to RS-422,
RS-485 (2-wire), or RS-485 (4-wire). Refer to the following information to determine the proper
settings for your board.
Jumper Settings
The two on-board 30-pin jumpers are used to select between the RS-232 and RS-422/485 serial
interfaces. If you select RS-422/485, then you will also need to set the DIP Switches to select
between RS-422, RS-485 (4-wire), and RS-485 (2-wire). Note that the two ports can be configured
independently.

CP-134U Series User’s Manual Hardware Installation
Plugging the Board into an Expansion Slot
Since the CP-134U series board’s IRQ number and I/O address are automatically assigned by the
PCI BIOS, the board MUST be plugged 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 your computer is turned off before
installing any serial 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).
Step 5: Plug the CP-134U board firmly into a free 32-bit PCI 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 Moxa PCI and Universal PCI boards must be assigned unique IRQ and I/O addresses. Both
addresses are assigned automatically by the PCI BIOS.
Step 9: Proceed with the software installation discussed in the next chapter, “Software
Installation.”

for Windows (2003/XP, 2000, 98/95, NT), DOS, Linux, and SCO. 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 up to 4 CP-134U boards can be installed in one system,
provided sufficient I/O address and IRQ number resources are available.
Windows 2000/XP/2003, Windows XP Embedded, Windows NT, Windows 95/98, DOS, FreeBSD,

CP-134U Series User’s Manual Software Installation
Windows 2003/XP
In this section, we describe the installation procedure for Windows XP. The installation procedure
for Windows 2003 is similar.
Windows 2003/XP support up to 256 serial ports, from COM1 to COM256. In order to utilize fully
Windows 2003/XP’s multi-process/multi-thread advanced features, pure 32-bit Windows 2003/XP
device drivers were developed 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-134U driver for the first time under
Windows XP. First, make sure the board or boards have already been plugged into the system’s
PCI or PCI-X slot(s).
NOTE If you have already installed a CP-134U or other Moxa Smartio/Industio board in your computer,
and you install 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.
1. After plugging the board into an expansion slot and powering
on your PC, Windows XP will automatically detect the new
board, and the Found New Hardware window will open in
the bottom right corner of the Windows desktop.
2. The Welcome to the Found New Hardware Wizard window will open automatically.
Select Install from a list or specific location (Advanced), and then click on Next to
continue.

CP-134U Series User’s Manual Software Installation
3. Select Search for the best driver in these locations, check Include this location in the
search, and then click on Browse. Navigate to the \CP-134U\Software\Win2K-XP-2003
folder on the software CD, and then click on Next to continue.
4. Wait while the installation wizard searches. The next window that opens cautions you that
although this software hasn’t passed Windows Logo testing, the driver has been tested and
shown that it can support the Windows OS. Click on ContinueAnyway to proceed.
