Chapter 1 Introduction
Moxa’s CP-118U 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.

CP-118U User’s Manual Introduction
Overview
Smartio—The Smart Multiport Async Solution
CP-118U 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-118U 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-118U 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-118U 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-118U
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-118U 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-118U 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
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.

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.
RTS
To ensure precise timing control when using 2-wire RS-485 transmission, we recommend that you
configure your CP-118U Series ports as described below.
There are 2 methods for controlling 2-wire RS-485 transmission.
Method 1
The following method is commonly used for 2-wire RS-485 transmission:
sio_SetWriteTimeouts(port, 0); /* Set sio_write() into block mode if for Windows NT and
Windows 95/98 */
sio_RTS(port, 1); /* Turn on RTS signal. The RS-485 port is ready for
transmitting data. */
sio_write(port, buff, 10); /* Write 10 byte characters in "buff". The function blocks
until the last character is transmitted */
sio_RTS(port, 0); /* Turn off RTS signal. The RS-485 port is ready for
receiving data. */
sio_read(port, buff, 10); /* Read 10 bytes */
Method 2
The PComm or API-232 library includes a dedicated RS-485 function that integrates the functions
described in Method 1 above into one function:
sio_putb_x(port, buff, tick ); /* 1. Turn on RTS and ready for transmitting data.
2. Send data.
3. Wait for tick time.
4. Turn off RTS and ready for receiving data. */
To see more detailed information about these functions, refer to the PComm library’s on-line Help
file for Windows 95/98/NT/2000/XP/2003.

Chapter 5 Pin Assignments
The CP-118U board has a female DB62 connector on the board, with various connection options
available for connecting from the board to your serial devices. In this chapter, we give pin
assignments for the board side connector, as well as pin assignments for device side connectors for
the different connection options.
The CP-118U board supports RS-232, RS-422, 4-wire RS-485, and 2-wire RS-485. Note that 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 one driver for broadcasting
systems. 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-118U board 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.

Common CP-118U 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 CP-118U 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
into a 32-bit PCI slot. 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-118U Series board. In this
case, enter the BIOS and make sure there is an available IRQ under PCI/PnP settings.
2. The MOXA CP-118U board and driver are activated but cannot transfer
(transmit/receive) data.
Hardware Causes and Solutions:

Chapter 6 Troubleshooting
a. Make sure the cable wiring is connected correctly. Refer to the “Connection Cables and
Cable Wiring” chapter for correct cable connections.
b. The cable or the board could be defective. Try other ports, cables, or boards to verify
this, or use the PComm Diagnostic utility to test the MOXA board and port conditions.
If Diagnostic reports an error, replace the faulty components.
Software Causes and Solutions:
a. CP-118U 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 control application might not be written correctly according to the
corresponding API of the operating system. To check this problem, run another
application that you know is correct, or use the utilities provided by Moxa (such as
Pcomm Terminal emulator or HyperTerminal under Windows NT and Windows 95/98).
CP-118U User’s Manual Troubleshooting
Windows NT
This section is specifically for troubleshooting problems for 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.
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-118U 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).
This could be caused by an IRQ or memory conflict with other ISA Bus adapters, such as
LAN and SCSI boards, or the system BIOS. Refer to the corresponding problem in the
previous section, “General Troubleshooting,” for possible solutions.
Windows 95/98
This section is specifically for troubleshooting under Windows 95/98. For general problems and
solutions, see the previous section, “General Troubleshooting.”
1. The system fails to find the CP-118U Series board!
The board(s) is (are) not plugged in properly.
2. The slot the boards are plugged into is defective. Try another slot until you find one that
works.
The board might be defective.
3. After the system reboots, the error message “CP-118U Series (BusNo=x, DevNo=x,
Port1=COMx) interrupt number is invalid!” appears.
This indicates that the MOXA board was found, but the IRQ conflicts with another adapter.
Make sure the MOXA board’s IRQ does not conflict with other adapters’ IRQ. Check the PCI
BIOS IRQ settings and select an available IRQ for MOXA boards.

Appendix A Technical Reference
CP-118U User’s Manual Technical Reference
PCI
The 32-bit CP-118U Series board complies with PCI Specifications 2.1, and the IRQ and I/O
address hardware configuration is automatically assigned by the PCI BIOS. This means that you
must plug in the board before installing the driver.
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-sensitivity or
slot-dependency. 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-118U Series boards are allowed in one system. When installing more than one board,
remember the order the boards are installed to distinguish the installed boards from each other.
MOXA UART
The MOXA UART is an intelligent asynchronous controller that supports one full duplex channel
that simultaneously transfers data at a transmission speed of 921.6 Kbps. To increase overall data
throughput, special features such as on-chip FIFO and on-chip hardware flow control are used to
reduce the number of interrupts to the onboard CPU, helping to prevent data loss.
