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.
1-2 CP-132U Series User’s Manual
Introduction
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.

Port number
This is the port ID of the port. Application software uses port number (ID) when referring
to a port. Consequently, port numbers must be unique.
Port numbers can be set to any number between 0 and 255 (inclusive). However, you must
ensure that each port is assigned a unique port number. If you are developing your own
application software, then you may want to select port numbers that take into consideration

the structure of the program.
TxD buffer size
The TxD buffer is the transmission (output) buffer allocated by the system for each port.
RxD buffer size
The RxD buffer is the receiving (input) buffer allocated by the system for each port.
F5 Group Edit
This is a convenient function that allows you to edit the configuration of several ports at
one time as a group.
Loading the Driver
After completing the setup procedure, run BIN\DP-DRV.EXE from the DOS prompt to
load the driver. The driver will automatically detect the boards that have already been
installed. If one or more board is detected, you will see a message similar the following:
Smartio/Industio Family DOS driver Version 1.5
Setup driver …

RS-485 Programming
If you intend to use your CP-132UL Series board for RS-485 applications, you can refer to
the RS-485 programming guide below, and also see the chapter, “Connection Cables and
Cable Wiring,” for more details about RS-485 operation.
The CP-132UL Series supports only 2-wire half-duplex RS-485 communication. In this
case, the data+/- pins are used for both data transmitting and receiving, depending on the
mode selected. Moxa’s own ADDC™ (Automatic Data Direction Control) technology is
used to switch between transmitting and receiving.
ADDC™ (Automatic Data Direction Control)
ADDC™ is the best method for switching between transmission and receiving when using
2-wire RS-485.
When using ADDC™, additional code is not required to switch between data transmitting
and receiving, since the switching mechanism is managed automatically by the board’s
built-in intelligent hardware mechanism. This means that RS-485 programming using
ADDC™ mode is just as simple and straightforward as RS-232 or RS-422 programming.

RS-422/485 Pinouts and Cable Wiring
RS-422 Interface
The RS-422 standard uses a balanced voltage digital interface to allow 9600 bps
communication over cables of up to 4000 feet in length. Ten receivers can be connected to
any one driver for broadcasting systems.
RS-485 Interface
The RS-485 standard is an enhanced version of the RS-422 balanced line standard. It
allows multiple drivers and receivers to work on a multidrop network. A maximum of 32
drivers and 32 receivers can be set up on a multidrop network.
The CP-132UL Series supports both 2-wire half-duplex and 4-wire full-duplex RS-485
communications. In 2-wire RS-485, Data+/- pins are used for both data transmitting and
receiving, depending on the RTS signal.

Connection Cables and Cables Wiring
Impedance Matching and Termination Resistors
When using RS-422/485 serial communications, an electrical signal that travels through
two different resistance junctions in a transmission line will sometimes give rise to signal
reflection due to the impedance mismatch. Signal reflection causes signal distortion, which
in turn contributes to communication errors. The solution to this problem is to establish the
same impedance at the ends of the transmission line, as in the line itself, by terminating the
ends of the line with resistors.

Chapter 6Troubleshooting
Common CP-132UL Series problems and possible solutions are listed below. If you still
have problems after reading this chapter, contact your dealer or Moxa for help, or use the
Problem Report Form at the end of this manual to report problems to your dealer.
General Troubleshooting
1. The MOXA PCI board cannot be detected by the MOXA driver while installing
the driver.
Hardware causes and solutions:
a. The board is not installed in the computer. Please install it.
b. The board is not properly plugged into the system. If this is the case, re-plug the
board in a 32-bit PCI. It is also possible that a slot has malfunctioned. In this case,
try other slots until you find one that works.
c. The motherboard does not have an available IRQ for the CP-132UL Series board.
In this case, enter the BIOS and make sure there is an availalbe IRQ under PCI/PnP
settings.
2. The MOXA board and driver are activated but cannot transfer (transmit/receive)
data.
Hardware Causes and Solutions:
a. Make sure the cable wiring is connected correctly. Refer to the “Connection Cable
and Cable Wiring” chapter for correct cable connections.
b. The cable or the board are probably defective. Try other ports, cables, or boards to
verify this, or use the PComm Diagnostic utility to test the MOXA board’s and port
conditions. If Diagnostic reports an error, replace the faulty components.
Software Causes and Solutions:
a. CP-132UL Series boards will check the line status (CTS) before transmitting data
if the RTS/CTS flow control feature is set to Enable in the configuration or
application program. Refer to the Connection Cables and Cable Wiring chapter for
proper wiring diagrams, and check the line status of the suspected port using the
diagnostic LED indicators on the mini tester.
b. The board controlling application might not be correctly written according to the
corresponding API of the operating system. To check this problem, run another
existing and known good application or use the utilities provided by Moxa (such
as Pcomm Terminal emulator or HyperTerminal under Windows NT and Windows
95/98).

Windows NT
This section is specifically for troubleshooting under Windows NT. For general problems
and solutions, see the previous section, “General Troubleshooting.”
1. After the system reboots, the error message “Another driver in the system, which
did not report its resources, has already claimed the interrupt used by xxx.”
appears in the Event Log.
This indicates the MOXA board was found, but the IRQ is conflicting with another
adapter. Please check the PCI BIOS IRQ settings first and then select an IRQ that is
available.
2. After the system reboots, the error message “Cannot find any configured MOXA
Smartio/Industio Series board!” appears in the Event Log.
Make sure the PCI board is seated firmly in the expansion slot.
3. The COM number of the CP-132U Series conflicts with others.
The COM numbers of different boards happen to be the same. Try changing the COM
number mappings.
4. Windows NT system panic (blue screen).
The possible reason is an IRQ or memory conflict with other ISA Bus adapters, like
LAN and SCSI boards, or the system BIOS. Refer to the corresponding problem in the
previous section, “General Troubleshooting,” for possible solutions.

PCI
The 32-bit CP-132UL Series board complies with PCI Specifications 2.1. The IRQ and I/O
address hardware configuration is automatically assigned by the PCI BIOS. This means that
you must first plug in the board before installing the driver software.
As opposed to ISA slots, different PCI slots in the same PC may have different bus
numbers and device numbers with respect to the PCI specifications. The same PCI board
will have different system configurations if switched to a different PCI slot; this is called
slot-sensitive or slot-dependent. This may also apply to PCI slots in a PC with a different
motherboard, which may use different device number sets. For example, some use 17, 18,
19, and 20 for identifying the respective PCI slots, but some use 11, 12, 13 and 14.
Due to slot-dependency, it is necessary to re-configure the driver software once the
board is plugged into different PCI slots.
Up to 4 CP-132UL Series boards are allowed in one system. When installing more than one
board, please remember the order the boards are installed to distinguish the installed
boards from each other.
