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.

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.

Introduction
CP-132U Series User’s Manual
1-3
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

CP-132UL Series Block Diagram
CP-132UL Series boards’ hardware configuration for IRQ number and I/O address is
automatically assigned by the PCI BIOS. This means that the board MUST be plugged in
first before installing the driver software.
