This chapter provides information you should know before using the product.
About the Board
This product is a PCI Express bus-supported b o a rd d esign ed fo r extending RS-232C compatible serial
communication functionality on your PC.
The < COM-2C-PE > has two RS-232C-standard serial ports.
The < COM-4C-PE > has four RS-232C-standard serial ports.
The < COM-8C-PE > has eight RS-232C-standard serial ports.
With a 128byte built-in FIFO buffer for transmission and reception of each channel, the product s upports
a baud rate of up to 921,600bps. Up to 16 boards can be mounted on a single PC and the range COM1 COM256 can be set. It also comes with a Windows/Linux driver, which allows boards to be used as
OS-standard COM ports.
This product supports CONTEC-defined driver library “API-PAC(W32)” that provide local routines.
Features
- Max. 921,600bps RS-232C Serial Communication
The < COM-2C-PE > has two RS-232C-standard serial ports.
The < COM-4C-PE > has four RS-232C-standard serial ports.
The < COM-8C-PE > has eight RS-232C-standard serial ports.
Baud rates from 2 to 921,600bps can be set for each port. When using the bundled “Stan dard C OM
Driver Software” and “Driver library API-PAC(W32)”, baud rates from 15 to 921,600bps can be set.
- Possibly used as Windows, Linux-standard COM ports, using the bundled driv er library
Comes with a driver software that allows the boards to be used under Windows / Linux in the same way
as COM ports on the PC. Under Windows, the product supports the OS-standard Win32 API
communication function as well as Visual Basic MSComm. Under Linux, OS-standard tty driver’s
standard-function can be used. In additi on, supplies a diagnostic pr ogram to confirm hardware o peration
and to perform a communication test with equipment.
- Max. 16 boards can be installed as configured in the range COM1 - COM256.
Up to 16 boards can be mounted on a single PC.
COM1 - COM256 can be set using the device manager.
- Each channel is equipped with separate 128-byte FIFO buffers for transmit and receive.
Employed a buffer memory 128-byte dedicated to transmission and 128-byte for each channel.
These are FIFO format, useful for high speed communications and to reduce the load to the CPU when
transmitting/receiving. As the device manager can be use d to enabl e/disable t he use of FIFO and set the
FIFO trigger size, this pe r mits op er ati on to be ad justed to achiere optinal performance for your system.

1. Before Using the Product
- The boards use the same easy-to-use 9-pin D-SUB connectors as are used on a PC.
(For COM-2C-PE only)
Using the most versatile general-purpose 9-pin D-SUB conn ector for RS-232C , the p roduct allows you
to use commercial cables which support the RS-232C standard.
- To suit your application, cables and connectors are available as optional.
COM-2C-PE : Straight cables (1.8m), cross cables (1.8m) and 9-pin D-SUB connectors (male or
female type) for creating your own cables are available as optional.
COM-4C-PE : Distribution cable for 4channels (PCE37/9PS, PCE37/25PS) and 37-pin D-SUB
connectors (male or female type) for your own cables are available as optional.
COM-8C-PE : Distribution cable for 8channels (PCE78/9PS, PCE78/9PS) and 78-pin D-SUB
connectors (male or female type) for your own cables are available as optional.
- The control line for RS-232C can be controlled and monitored by software.
The control lines for RTS, CTS, DTR and DSR can be controlled and monitored using an application.
The lines can be controlled or monitored by software from the application.
- Driver library API-PAC(W32) is supported.
API-PAC(W32) is library software based on Win32 API routines (DLL), which provides local routines
specific to CONTEC. You can create high- speed applicati on software taki ng advantage of the CONT EC
hardware using various programming languages that support Win32 API functions, such as Visual Basic
and Visual C++.

1. Before Using the Product
Support Software
You should use CONTEC support software accor d ing to your purpose and development environment.
Standard COM Driver Software (Bundled)
The purpose of this software is to allow the CONTEC serial communication boards (cards) to be used under Windows
or Linux in the same way as the standard COM ports on the PC. By installing additional boards (cards), you can use
COM ports in the range COM1 - COM256.
The boards can be used for all types of se rial communications such as for remote a ccess service (RAS) and
uninterruptible power supply (UPS) applications.
Under Windows, the serial ports can be accessed using the standard Win32 API communication routines (CreateFile( ),
WriteFile( ), ReadFile( ), and SetCommState( ), etc.) The serial ports are also compatible with the Visual Basic
communication control (MSComm). Supports the communication class of .NET Framework 2.0 (SerialPort class).
Under Linux, the serial ports are compatible with the operating system's standard tty driver. The standard routines
including open( ), close( ), read( ), write( ) are supported.
< Operating environment >
OS Windows 7, Vista, XP, Linux etc..
You can download the updated version from the CONTEC’s Web site (http://www.contec.com/comdrv/). For more
details on the supported OS, applicable language and new information, please visit the CONTEC’s Web site.
CAUTION
The maximum number of COM ports able to be used depends on the configuration of your OS.
Driver Library

2. Setup
This chapter explains how to set up the board.
What is Setup?
Setup means a series of steps to take before the product can be used.
Different steps are required for software and hardware
The setup procedure varies with the OS and applications used.
Using the Board under Windows
Using the Standard COM Driver Software COM Setup Disk
This section describes the setup procedure to be performed before you can start developing application
programs for the board using the bundled CD-ROM “Standard COM Driver Software -
COM Setup Disk”.
Taking the following steps sets up the software and hardware. You can use the diagnosis program later
to check whether the software and hardware function normally.
Step 1 Setting the Hardware
Step 2 Installing the Hardware
Step 3 Initializing the Software
On the CD-ROM, refer to the \PCI\Readmee.txt file and the installation instruct io ns fi les for e ach OS
located in the \PCI\InstDoc.
If Setup fails to be performed normally, see the “Setup Troubleshooting” section at the end of this
chapter.
Using the Board under Windows
Using the Driver Library API-PAC(W32)
Refer to the API-PAC(W32) "Hardware Installation Procedure (HWINSTU.CHM)" help file for the
procedure to follow when using API-SIO in the "Driver Library API-PAC(W32)".
If using API-SIO from API-PAC(W32), install from API-PAC(W32) instead of from the supplied
CD-ROM.
