Notice
This guide is designed for experienced users to setup the syste m in
the shortest time.
Safety Precautions
Always completely disconnect the power cord
from your board whenever you are working
on it. Do not make connections while the
power is on, because a sudden rush of power
can damage sensitive electronic
components.
Always ground yourself to remove any static
charge before touching the board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap
at all times. Place all electronic components
on a static-dissipative surface or in a
static-shielded bag when they are not in the
chassis.

1.7 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close”
a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

A pair of nee
dle-nose pliers may be helpful when working with
jumpers. If you have any doubts about the best hardware
configuration for your application, contact your local distributor or
sales representative before you make any change. Generally, you
simply need a standard cable to make most connections.

1.23 Driver Installation
The PFM-C42C supports Linux and Windows XP platforms. It comes
with a CD-ROM that contains all drivers and utilities that meet your
needs. When your platform is Windows XP please following the
sequence below to install the drivers, when your system is Linux,
you don’t need to install the driver just process the Mini PCI RS-232
module set up in Linux
Installing Mini PCI RS-232 drivers in Windows XP
Once the card is installed and the computer is restarted, Windows
will detect the board and attempt to load the drivers for it.
1. Windows will detect a “PCI Serial Port”. Select “Install
from a list or specific location (Advanced)” as the shown of
figure 1. Click “Next.”
PFM-C42C Quick Installat ion Guide 1-20

Figure 1
2. Select “Search for the best driver in these locations.”, next
select “Include this location in this search:” and then click
“Browse” to open the “CD-ROM/Driver/PFM-C42C Mini
PCI RS-232 Module driver V1.0 for Windows” file as
shown in figure 2 . Click “Next.”
Figure 2
3. Windows has found an updated driver for this device as
shown in figure 3. Click “Next.”

4. The “Completing the Found New Hardware Wizard” dialog
Appears as shown in figure 3, click “Finish.”
5. Repeat the above process for the second, third, fourth,
fifth AAEON PCI Communications Port.
6. Please re-start your Windows.
Finalizing Mini PCI RS-232 module settings
Check your Windows System/Device Manager to confirm proper
installation of Mini PCI RS-232 drivers:
Multifunction adapters
AAEON OX16PCI954 PCI UARTs
AAEON OX16PCI95x PCI bridge
Ports(COM & LPT)
4-port Mini PCI module will show 4 AAEON PCI
Communications Port and 2-port Mini PCI module will show 2

Mini-PCI RS-232 module set up in Linux
If the module is a 4-port Mini PCI, you don’t need to proceed with the
set up process, you can use it directly. 2-port Mini PCI module
please use following the sequence below to set up the module.
1. Open the Terminal screen and make a
cat /proc/tty6/driver/serial command to check your
COM port settings.
PFM-C42C Quick Installation Guide 1-23
PC/104 Peripheral Module PFM-C42C
As the screen showing, use 16550A to be UART prefix is
the system
COM ports, and we can see this system have
2 COM ports, leave each other ttyS0, ttyS1.
2. Make lspci -v command to find OXmPCI952 IRQ and I/O
address
As the screen showing, we can find ”Serial controller:
Oxford Semiconductor Ltd:” this alphabetic string then to
see the next line have IRQ number and the next have
I/O address
3. Open the file: /etc/rc.local and add two commands
setserial /dev/ttySX1 port IOADDR1 irq Y uart 16950 baud_base 115200
setserial /dev/ttySX2 port IOADDR2 irq Y uart 16950 baud_base 115200
In above command line X1,X2 is the COM port number
and it must be beyond beforehand. So in this case X1 is 4,
X2 is 5. Besides, Y is IRQ number . Finally, we can set the
I/O address individually.
setserial /dev/ttyS4 port 0xe000 irq 9 uart 16950 baud_base 115200
PFM-C42C Quick Installat ion Guide 1-24
PC/104 Peripheral Module PFM-C42C
setserial /dev/ttyS5 port 0xe100 irq 9 uart 16950 baud_base 115200
4. Please re-start your computer.
5. Make cat /proc/tty/driver/serial command to see if the
display is as following, if yes you already set it up.
