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
Industio CP-134U Series User’s Manual
1-3
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

CP-134U
The Industio 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.

Industio CP-134U Series User’s Manual

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.
Jumper pins:
Top for Port 1,
Bottom for Port 2
RS-422/485:
Cover the left two
columns of pins with the
jumper to select the
RS-422/485 option.
RS-232:
Cover the right two
columns of pins with the
jumper to select the RS-232
option.
DIP Switch Settings
Refer to the figures on the following two pages to see how to select between RS-422,
RS-485 (2-wire), and RS-485 (4-wire).

stio CP-134U Series Board
Step 1: Power off the PC.
Warning! To avoid damaging your system and board, make sure your computer is
turned off before installing any board.
Step 2: Remove the PC’s cover.
Step 3: Remove the slot cover bracket if there is one.
Step 4: Plug the Industio CP-134U Series control board firmly into a free 32-bit PCI slot,
or the CP-134U Series board into both a 32-bit/64-bit slot.
Step 5: Fasten the holding screw to fix the control board in place.
Step 6: Replace the system cover.
Step 7: Power on the PC. The BIOS will automatically set the IRQ and I/O address.
Note! Each board must occupy one unique IRQ and two 8-byte I/O addresses,
which are assigned automatically by the PCI BIOS. However, you can
select a free IRQ number manually via the PC’s BIOS setup for the PCI slot,
but normally this method is not available for the I/O address. The possible
IRQ numbers are 2, 3, 4, 5, 7, 10, 11, 12, and 15. The possible I/O addresses
are from 0x0000 to 0xFFFF.
Step 8: Proceed with the software installation discussed in the next chapter, “Software
Installation.”

Windows NT
Windows NT supports up to 256 serial ports, from COM1 to COM256. To fully integrate
the advanced features of Windows NT, Moxa has developed multi-process and multi-thread,
pure 32-bit Windows NT device drivers for the Industio CP-134U Series multiport boards.
The driver conforms to the Win32 COMM API standard.
 To install the driver for the first time, go directly to the next section, “Installing the
Driver.”
 If the driver is already installed, and you want to re-configure the board and port(s),
add more boards, or delete boards, refer to the section “Configuring the Board and
Ports.”
 To update or remove the driver, refer to either, “Updating the Driver” or “Removing
the Driver.”
