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

for PCI Express 2ch

COM-2PD-PE

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

change without notice.

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

The < COM-2PD-PE > 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 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 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, this permits operation to be

adjusted to achieve optional performance for your system.

This product is a PCI bus-supported board designed for

extending RS-422A/485 compatible serial communication

functionality on your PC.

The < COM-2PD-PE > has two RS-422A/485-standard serial

ports.

Higher noise-resistant models with isolation between channels

and between 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-

P

AC(W32)” that provide local routines.

To suit your application, cables and connectors are

available as optional.

9-pin D-SUB connectors (male or female 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, 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 application software taking advantage of

the CONTEC hardware using various programming languages

that support Win32 API functions, such as Visual Basic and

Visual C++.
