1. Before Using the Product
1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This product is a PCI bus-supported board designed for extending RS-422A/485 compatible serial
communication functionality on your PC.
The < COM-2PD(PCI)H > has two RS-422A/485 communication ports.
The < COM-4PD(PCI)H > has four RS-422A/485 communication ports.
Higher noise-resistant models with isolation between a PC and bus line as well as a surge protection
circuit for communication ports. With a 128byte built-in FIFO buffer for transmission and reception of
each channel, the product supports a baud rate of up to 921,600bps. 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.
The COM-2PD/4PD(PCI)H boards are backward compatible with the CONTEC COM-2PD/4PD(PCI)
boards. The COM-xPD(PCI)H can therefore replace the COM-xPD(PCI) in an existing system.
Features
- Max . 921,600b ps RS-422 A/485 Serial Communication
The < COM-2PD(PCI)H > has two RS-422A/485-standard serial ports.
The < COM-4PD(PCI)H > has four RS-422A/485-standard serial ports.
Baud rates from 2 to 9 21, 60 0b ps ca n be se t. Wh en using the bundled “Standard COM Driver Software”
and “Driver library API-PAC(W32)”, baud rates from 15 to 921,600bps can be set.
- Po ssib ly used as Windows , Linux-stand ard COM po rts, using the bundled driv er library
Comes with a driver software that allows the products 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.
- Isolation between channels and between PCs, surge protection for all signal lines
The channels are electrically isolated from each other and from the PC.
As isolation is provided between channels as well as isolation of the bus, this prevents electrical noise
between channels as well as betwee n the PC a nd external cir cuits. A s surge pr otection i s provide d on all
signal lines, you can safely use the boards in environments where you are concerned about surges
causing incorrect operation or damage to the PC.
- Max. 16 boards can be in stalled as configu red in the range C OM1 - COM2 56.
Up to 16 boards can be mounted on a single PC.
COM1 - COM256 can be set using the device manager.
COM-2PD(PCI)H, COM-4PD(PCI)H

1. Before Using the Product
- 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 used to enable/disable the us e of FIFO and set the FIFO trigger size, you
can build an optimum system according to your use.
- To suit your application, cables and connectors are available as optional.
COM-2PD(PCI)H :9-pin D-SUB connectors (male or female type) for your own cables are available as
optional.
COM-4PD(PCI)H :Distribution cable for 4channels and 37-pin D-SUB connectors (male type) for your
own cables are available as optional.
- The control line for RS-422A/485 can be controlled and monitored by software.
The control lines for RTS+, RTS-, CTS+ and CTS- can be controlled and monitored using software.
- 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++.
Support Software
You should use CONTEC support software accor d ing to your purpose and development environment.
Standard COM Driver Software
The purpose of this software is to allow the CONTEC serial communication boards to be used under Windows or Linux
in the same way as the standard COM ports on the PC. By installing additional boards, 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 access s ervi ce ( R AS) 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.
COM Setup Disk
(Bundled)
< Operating environment >
OS Windows 8, 7, Vista, XP, NT, Me, 98, 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.

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 (HWINST.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
