UICK START
It is recommended that you install the software package before
installing the PCI Express Mini Card (mPCIe) in your computer. You
can install the software
1
using either a stand-alone installer
downloaded from the website or an optional Software Master CD.
Run the installer you downloaded (or autorun.exe on the Software
Master CD) and follow the prompts to install the software.
Please note: during the installation you may be prompted regarding
the installation of non-WHQL-certified drivers; please carefully
confirm the digitally signed source of the drivers and accept the
installation.
Once the software has been installed, shut down your system and
carefully install the mPCIe card.
Re-start your system. Once the computer finishes booting your
new serial ports should already be installed and ready for use; you
can confirm this by launching Device Manager and looking under
the “Ports” section. If, for any r
eason, the mPCIe or its ports
display a warning triangle, right-
click and select “Update Driver”.

In Linux or OSX please refer to the instructions in those directories.

NTRODUCTION
PCI Express Mini Card (mPCIe), a low-profile small-footprint bus
standard originally intended for adding peripherals to notebook
computers, has become the de-facto standard for high-
performance, small form-factor devices in many applications.
•
1-, 2- or 4- port RS422 / 4-wire 485 serial port on mPCIe
•
Tru-
Iso™ provid

•
RoHS and Industrial temperature standard
The mPCIe-ICM422 family of cards feature high performance
16C950-class UARTs. Each port is capable of communication
speeds up to 921.6kbps and has 128-byte deep transmit and
receive FIFOs which protect against data loss in multitasking
operating systems, reduce CPU utilization, and improve data
throughput. The advanced integrated circuit supports a wide
variety of custom baud rates, and any rates not otherwise
achievable can be supported via a factory-installed custom crystal
oscillator.
The ports provided by the card are 100% software compatible with
industry-standard serial COM devices. In addition, they provide
Tru-
Iso™ port
-to-port and port-to-PC isolation.
Communication is possible either with custom application
software, with off-the-shelf applications (such as HyperTerminal),
or with provided samples and utilities, including WinRISC™
(“Windows Really Incredibly Simple Communication”).
The serial ports on the device are accessed using a low-profile
latching 5-pin Hirose connector. Optional breakout cable kits are
available, and bring each port connection to a panel-mountable
DB9-M.
There are no user-selectable option settings for this device family.

ETTINGS
This product has no user configurable hardware options. All
possible configuration settings can be performed through the
industry standard UART drivers in your operating system.
The RS422 ports are terminated by a 120Ω load in series with a
0.01µF capacitor across the Rx+/Rx- pair.
