PCI –compliant I/O

RS-422A/485 2ch Serial I/O board

COM-2DL-PCI

-Max. 230,400bps RS-422A/485 Serial Communication

COM-2DL-PCI has two RS-422A/485-standard serial ports.

Baud rates from 15 to 230,400 bps can be set.

- Boards can be used as standard serial ports when

operating in a Windows

These products come with a driver library that allows the

boards to be used under Windows in the same way as

COM ports on a PC.

Under Windows, these boards

support the OS-standard Win32 API communication

function as well as Visual Basic MSComm.

The driver

library also includes a diagnostic program to confirm

hardware operation and to perform communication tests.

- 16 boards (max) can be installed with an access

range from COM1 to COM256.

Up to 16 boards can be installed in a single PC.

COM1 - COM256 can be set using the device manager.

- Each channel is equipped with separate 64-byte

FIFO buffers for transmit and receive.

Each

individual

channel

has

FIFO

buffer

memory

(transmission: 64 bytes, reception: 64 bytes).

This feature is useful for high speed communications and

to

reduce

the

load

to

the

CPU

during

transmitting/receiving.

- Cables and connectors are available as optional.

9-pin D-SUB connectors (male or female type) for creating

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+, CTS- can be

controlled and monitored using an application.

This PCI board was designed for extending RS-422A/485

compatible serial communication functionality on your PC.

COM-2DL-PCI has two RS-422A/485 communication

ports.

With a 64 byte built-in FIFO buffer for transmission and

reception of each channel, the product supports a baud

rate of up to 230,400bps.

It also comes with a Windows

driver, which allows boards to be used as OS-standard

COM ports.
