PCI Express Board User’s Manual Introduction
Overview
MOXA’s new PCI Express Multiport Serial Boards, named CP-118EL, CP-168EL, and CP-104EL,
are designed for POS and ATM applications and for use by industrial automa t i on system
manufacturers and system integrators. The boards are compatible with all popular operating
systems, and each of them supports data rates of up to 921.6 Kbps, and provides full modem
control signals, ensuring compatibility with a wide range of serial peripherals. In addition,
CP-118EL, CP-168EL, and CP-104EL work with PCI Express ×1, allowing the boards to be
installed in any available PCI Express slot (including ×1, ×2, ×4, ×8, ×16, ×32).
PCI Express Solution
The boards comply with PCI Express Spec. 1.1. 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 (CP-118EL has DIP
Switches, CP-168EL and CP-104EL are RS-232 only), but the ports’ transmission parameters are
configured after the boards are installed. The PCI BIOS automatically assigns the IRQ and I/O
addresses. For this reason, you must plug the boards into the computer before installing the drivers.
For more PCI Express information, refer to the “Technical Reference” appendix.
Surge Protection
The PCI Express boards come with built-in 15 KV ESD surge protection to prevent damage to the
boards from lightning or high potential voltage. The surge protection feature makes the PCI
Express boards suitable for industrial, factory-type applications, and for use with applications that
are subject to severe weather conditions.
ADDC™ (Automatic Data Direction Con trol) 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-118EL board, eliminating the need for software
interference. 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 PCI Express boards are compatible with all major industrial platforms, including Windows
2000/XP/2003, DOS, and Linux. MOXA device drivers are provided for smoother installation,
configuration, and performance. In this manual, we provide installation details for Windows
2003/XP, Windows 2000, DOS, Linux, and SCO.

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.

MOXA PComm
PComm, a professional serial communication tool for PCs, is a software package that runs under
Windows NT/2000/XP/2003/95/98. PComm provides:
y A powerful serial communication library that simplifies serial programming tasks for most
popular programming languages. The serial communication library is useful for developing
applications for data communications, remote access, data acquisition, and industrial control
under Windows NT/2000/XP/2003/95/98, and is a simpler pr ogramming solution compared
to the more complex Windows Win32 COMM API.
y Useful utilities such as diagnostics, monitor, and terminal emulator.
y Illustrative sample programs.
y Comprehensive on-line documentation.
Installing PComm
To install PComm, run \Setup.exe from the Documentation and Software CD. Note that the
PComm diagnostics and monitor utilities are for MOXA boards only. To use these utilities, you
must have a MOXA board and the appropriate Windows (95/98/NT/2000/XP/2003) device driver
installed in your system. See the “Software Installation” chapter for instructions on how to install
the drivers.
After installing PComm, click Start, select Program Files, and then the PComm Lite group to
select from the list of utilities and documents.
PComm Programming Library
The serial communication library helps you develop serial communications programs for any
COM port that complies with the Microsoft Win32 API. This library facilitates the implementation
of multi-process, multi-thread serial communication programs, and greatly reduces the time
required to develop applications.
For a complete description of the library functions and sample programs for Visual C++, Visual
Basic, and Delphi, check the help file and the sample programs in the PComm directory.
Utilities
In this section, we provide brief descriptions of each utility. For more information about these
utilities, read the on-line help from the Documentation and Software CD.
Diagnostics (for MOXA boards only)
This convenient diagnostics program, which only works with MOXA boards and ports, provides
internal and external testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD, etc. The
diagnostics program allows the user to check both the hardware and software functions.
To run the diagnostics program, click Start Æ Program Æ PComm Lite Æ Diagnostic. A typical
test report for a MOXA board is as follows:
4-2
PCI Express Board User’s Manual Serial Programming Tools
Monitor (for MOXA boards under Windows 2000/XP/2003)
This useful port status monitoring program allows you to monitor data transmission of selected
MOXA COM ports. The program monitors data transmission/receiving throughput, and
communication line status, with data updated and displayed on the screen at regular time intervals.
Click a specific port to see a graph of the current communication parameters and status of that
port.
To run the Monitor program, click Start Æ Program Æ PComm Lite Æ Monitor.
4-3
PCI Express Board User’s Manual Serial Programming Tools
Terminal Emulator
Use Terminal Emulator to connect to your PC’s serial ports to check if data is being transmitted
correctly. Terminal Emulator features multi-windows, and supports VT100 and ANSI terminal
types. You can transfer data interactively, send patterns periodically, and transfer files using ASCII,
XMODEM, YMODEM, ZMODEM, and KERMIT protocols.
To run Terminal Emulator, click Start Æ Program Æ PComm Lite Æ Terminal Emulator.
RS-485 Programming
If you are using your CP-118EL Series board for RS-485 applications, in addition to reading this
section, you should also refer to the “Connection Cables and Cable Wiring” chapter for more
details about using RS-485.
The CP-118EL Series supports 2-wire half-duplex RS-485 and 4-wire full duplex RS-485
communication. Ports configured for 2-wire RS-485 use the Data+ and Data- pins for both
transmitting and receiving data. MOXA’s own ADDC ™ (Automatic Data Direction Control)
technology is used to switch between transmission and reception.
ADDC™
ADDC™ is the best method for switching between transmission and reception when using 2-wire
RS-485.
When using ADDC™, additional code is not required to switch between data transmission and
reception, since the board’s built-in intelligent hardware mechanism automatically manages the
switching mechanism. RS-485 programming using ADDC™ mode is just as simple and
straightforward as RS-232 or RS-422 programming.

CP-118EL
The CP-118EL board has a female SCSI VHDCI68 connector on the board, with various
connection options available for connecting from the board to your serial devices. In this chapter,
we provide pin assignments for the board side connector, as well as pin assignments for device
side connectors for the different connection options.
The CP-118EL 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. You can connect ten receivers 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 maxim um of 32 drivers
and 32 receivers can be set up on a multidrop network. The CP-1 18EL 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 PCI Express Series problems and possible solutions are as follows. 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 Express 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 PCI Express 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 PCI Express board. In this case,
enter the BIOS and make sure there is an available IRQ under PCI/PnP settings.
2. The MOXA PCI Express 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 “Pin Assignments”
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 the Diagnostic program reports an error, replace the faulty components.
Software Causes and Solutions:
a. PCI Express 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 diagnostics LED
indicators on the mini tester.
b. The board control application may 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 platform).

PCI Express
The PCI-SIG has defined a new I/O technology, PCI Express, which over time is expected to
replace the current I/O bus technologies PCI, PCI-X, and AGP.
One advantage of the serial architecture of PCI Express is the lower pin count for all PCI Express
devices compared to PCI and PCI-X. For example, a × 1 Link uses only 8 traces—significantly
less than a PCI bus, which uses a minimum of 74 traces. This more pin-efficient design not only
reduces manufacturing costs, it also greatly reduces the number of traces that are required on the
PCB, thus simplifying the routing of traces. Additionally, this architecture reduces the electrical
issues that limit the signaling rate of PCI and PCI-X.
The advantages of PCI Express compared to PCI, PCI-X, AGP, and CardBus include the
following:
y Support for multiple marker segments and emerging applications
y Cost effective implementation and manufacture
y Compatibility with the PCI software model
y Superior performance and scalability
y Support for new modules
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.
