Isolated RS-422A/485 2ch Serial I/O Board

for Low Profile PCI

COM-2PD(LPCI)H

* Specifications, color and design of the products are subject to

change without notice.

This product is a low profile sized PCI bus-supported board

designed

for

extending

RS-422A/485

compatible

serial

communication functionality on your PC.

This product has two 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.

Max. 921,600bps RS-422A/485 Serial Communication

This product has two RS-422A/485-standard serial ports.

Baud rates from 2 to 921,600bps can be set.

When using the

bundled “Standard COM 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 driver 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 addition, supplies a

diagnostic program to confirm hardware operation 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 between the PC and external circuits.

As surge

protection is provided 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 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 used to enable/disable the use

of FIFO and set the FIFO trigger size, you can build an

optimum system according to your use.

Support for Low Profile size slot / standard size slot

Bundled with each bracket for Low Profile size slot / standard

size slot.

Exchanges it for the standard size bracket when

mounting on the standard size slot.

To suit your application, cables and connectors are

available as optional

Distribution cable for 2channels and 44-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

application

software

taking

advantage

of

the

CONTEC

hardware

using

various

programming languages that support Win32 API functions,

such as Visual Basic and Visual C++.
