1 Introduction
Welcome to the MOXA CP-134U Series of industrial 4-port RS-422/485 serial boards for
the PCI bus.
The following topics are covered in this chapter:

Overview
Industio—The Industrial Multiport Async Solution
Moxa Industio
IndustioIndustio
Industio products are smart, multiport serial I/O solutions for industrial applications.
The Industio
IndustioIndustio
Industio CP-134U Series boards, including CP134-UI and CP-134UL, are designed
for a 32-bit PCI bus with the Plug and Play and Universal PCI feature. The ports for these
boards can be configured independently, with ports 1 and 2 set to the RS-232, RS-422, or
RS-485 interface, and ports 3 and 4 set to the RS-422 or RS-485 interface. Industio
products provide a reliable communication link over a longer distance (up to 4000 ft for
ports set to the RS-422/485 interface), and are suitable for industrial environments.
Connections with point-to-point full-duplex (RS-422 or 4-wire RS-485)or multidrop
half-duplex (2-wire RS-485) are available to meet user’s various needs. And each RS-485
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-134U series board, eliminating
the need for software interference. This means that Windows applications can manage
RS-485 ports without needing to write extra code for controlling the half-duplex protocol.
With their well-designed and fine-tuned device driver, Industio CP-134U boards make full
use of the 64 byte Tx/Rx FIFO and on-chip H/W flow control, so that they can transfer data
without loss even at speeds as high as 230.4 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 Industio CP-134U 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, TVSS
(Transient Voltage Surge Suppressor) technology is included in some models to protect the
board. An optical isolation option (2000V), and embedded surge protection (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.
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

Introduction

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 and
32/64-bit slot.
Operating System Support
The Industio CP-134U series is compatible with most major industrial platforms, including
Windows NT/2000/XP, Windows 95/98, and Linux. MOXA device drivers are provided
for smoother installation, configuration, and performance. In this manual, sections for
MOXA Windows NT, Windows 2000/XP, Windows 95/98, and Linux are included.
MOXA Serial Comm Tools
For application development, MOXA provides an easy-to-use serial communication library
called PComm
PCommPComm
PComm that runs under Windows NT/2000/XP and Windows 95/98. You can use this
library to develop your own applications using 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.
Board Applications
The board is suitable for many industrial applications, including:
 Multipoint data acquisition
 Factory automation
 Critical industrial control
 Remote serial device control
