Hardware Installation
1. Turn your PC’s power off, and shut off the power to any peripheral.
2. Remove the power plug from the plug socket.
3. Remove the cover from the computer case.

4. If fitted. Remove the metal cover plate on the rear of a free PCI slot.
5. Insert Universal PCI Multi-Port Communication Board into the free
PCI slot and screw it firmly on the bracket side.
6. Place the cover back onto the computer.
7. Insert the plug into the plug socket.
Driver Installation
For Windows®XP/Vista/Win7/8/10 (32/64 bit)
1. After the board is physically installed and the PC boots up, system will
detect the PCI Serial card and prompt for driver installation wizard,
please choose cancel.
2. Put CD driver bound with product in your CD/DVD ROM drive. Please
select autorun.exe, then select “Driver Installation”.
3. Select the product interface “PCI/PCI-104”.
4. Please select the O.S. version you are using, system will process the
driver installation step automatically.
5. Select driver language for your operation system.
6. Click “Next” to continue driver installation steps.
7. Click “Install” to continue driver installation steps. System will install
driver automatically. It takes about one minute.
8. Click “Finish” to end installation steps.
For Linux
1. Driver install
Please create a directory under root directory, e.g./temp, do
commands:
# cd/
# mkdir temp
After get driver file “snx_Vx.x.x.x.zip”. Copy file to/temp directory,
then extract and install, do commands:
# cp snx_Vx.x.x.x.zip/temp
# cd/temp
# unzip snx_Vx.x.x.x.zip

# cd/temp/snx
# make clean; make install
*************************************************************
* If system is Suse 9.0 and errors occur when
* “make clean; make install”, do commands:
* # cd/usr/src/linux/
* # make cloneconfig
* # make dep
* then do “make clean; make install” again in/temp/snx
*************************************************************
Load driver module, do command:
# modprobe snx
or
# insmod/temp/snx/driver/snx.ko (snx.o for kernel 2.4)
Check driver module, do command:
# lsmod | grep snx
Unload driver, do command:
# rmmod snx
2. Device node creation
Each serial port has one device node which is named “ttySNX?”
maximum up to 32 serial ports.
This setp will be done when do “make clean; make install”, if device
nodes aren't in/dev, do commands:
# cd/temp/snx/snxmknod
# ./snxmknod
This will create device nodes in/dev.
If there are more than two boards installed, serial port device naming
convention please refer to F1.

To Verify Driver Installation
Click on the “Device Manager” tab in System Properties, which you
access from the Windows Control Panel. You should see a “4-Port Serial
Card” under the “Multifunction adapters” item and “COM Port (COMx)”
under the “Ports (COM & LPT)”
Port Configuration
1. Configure Serial Port Settings
Please launch the “Device Manager”.
Right click the “SUNIX Serial Card” item from the “Multifunction
adapters” sub-tree and click “Properties”.
On the “Port Control” tab, select a port to configure.
* Click “OK” to approve the settings for the selected port.
* Click “Set to All” to approve the settings for all COM ports.
2. COM Port Number Settings
Under Port Number, select a COM number to assign to the
serial port. Click “OK” to approve the settings for the selected
port.

3. COM I/O Resource
User can read the COM “IO Range” and “IRQ” located in
system by selecting COM port.
IRQ and I/O address is automatically assigned by the
mainboard PCI BIOS automatically (before COM card driver
installing). User can NOT assign legacy ISA address (3F8, 3E8,
2F8, 2E8) for the specific COM port. But for IRQ setting, user
can set specific IRQ value for this PCI bus slot via mainboard’s
BIOS settings (not via SUNIX driver). But all COM ports will
share one IRQ value.
4. FIFO Settings
Select an Rx FIFO Trigger and Tx FIFO Size.
The default Rx FIFO Trigger is 112 bytes. The default Tx FIFO
Size is 128 bytes. Click “Set to All” to change this setting for all
serial ports on the board. Then click “OK” to save the settings.
Receive FIFO interrupt trigger level:
When the level of data in the receiver FIFO reaches this value,
a receiver data interrupt is triggered.

Transmit FIFO interrupt trigger level:
When the level of data in the transmit FIFO falls below this
value, a transmitter interrupt is triggered. Setting this value to
zero will not trigger an interrupt until the transmitter is
completely idle.
The FIFO trigger levels can be fine-tuned to gain optimum
performance, depending on system performance, baud rate
used levels of serial traffic etc.
5. Advanced Settings
User can control RS-232 communication in Advanced Port
Control page through “Advanced” settings.
Clock Rate
This is the “Data Rate" value for on board crystal frequency of
input clock. The baud rate can optionally be adjusted according
to the data rate required. The clock pre-divisor is used to divide
the input clock prior to baud rate generation.
This parameter must match with the oscillator (crystal)
frequency on the board. System default is 14745600 Hz. We do
NOT recommend for modification without SUNIX instruction.
User can click “Defaults” button back to manufactory settings.
