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.

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 to download the latest drivers and user’s manuals for all
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.

Chapter 2 Hardware Installation
The CP-118U Series hardware installation procedure is described in this chapter. Since the
CP-118U board’s IRQ number and I/O addresses are assigned automatically by the PCI BIOS, the
board MUST be plugged in before installing the driver.

DIP Switch Settings
CP-118U has three onboard DIP Switch arrays, each with 8 switches, referred to below and on the
board (see the above block diagram) as S1, S2, and S3. The switches are used to select one of four
serial interfaces—RS-232, RS-422, 4-wire RS-485, 2-wire RS-485—for each of the eight ports.
Note that S3 selects between RS-232 and RS-422/485, S2 selects between RS-422 and RS-485,
and S3 selects between 2-wire and 4-wire RS-485.
