RS-422A/485 1ch Serial I/O Board
with Isolation for PCI Express Low Profile
* Specifications, color and design of the products are subject to change
This product is a low profile sized PCI Express bus-supported board
designed for extending RS-422A/485 compatible serial communication
functionality on your PC.
The product has one 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 driver, which allows boards to be used as
OS-standard COM ports.

Max. 921,600bps RS-422A/485 Serial Communication
The product has one RS-422A/485-standard serial ports.
Baud rates from 30 to 921,600bps can be set.
Possibly used as Windows-standard COM ports, using the bundled
Comes with a driver software that allows the products to be used under
Windows 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. In addition, supplies a
diagnostic program to confirm hardware operation and to perform a
communication test with equipment.
Isolation between PCs, surge protection for all signal lines
Between PCs are electrically isolated. As isolation of the bus is provided,
this prevents electrical noise 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 -
Up to 16 boards can be mounted on a single PC.
COM1 - COM256 can be set using the device manager.
LEDs for operation check within
LEDs are installed to check the operations and enable you to view
Equipped with 2- piece terminal
The transmission line connection terminal that is linked to calbles can be
connected or disconnected to the board simultaneously. With tightened
screws that prevent the terminal coming off, you can safely use the
boards without unnecessary troubles.
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.
