______________________________________________
This chapter shows all Serial COM port settings that user came with usually,
such as COM port number, FIFO length(size), baud rate, IO address and
others.
The following topics covered in this chapter:
Configure Serial Port Settings
COM Port Number Settings
COM I/O Resource
FIFO Settings
Advanced Settings
25
___________________________________________________________________________________
Configure Serial Port Settings
After the board and serial port drivers are installed, please refer to following
instructions to configure Serial COM settings.
(1) Please launch the “Device Manager”.
(2) Right click the “SUNIX Serial Card” item from the “Multifunction
adapters” sub-tree and click “Properties”.
(3) 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.
26
___________________________________________________________________________________
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.
Note: In order to prevent system resource conflict, do not select “in use” port.
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.
27
___________________________________________________________________________________
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.
28
___________________________________________________________________________________
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 matches 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.

Appendix
______________________________________________
This chapter shows some problems that user came with usually. Also you can
check it if the PCI Express serial board can not work properly in your system
after following hardware and software installation steps. In addition, you could
contact with us for detail technical product information.
In this appendix, we cover the following topics.
Troubleshooting
Product Family
Contact Information
30
___________________________________________________________________________________
Troubleshooting
1. System fails to find the PCI Express serial board or COM port.
A: It may cause by following issue:
a. The board is not properly plugged into the PCI Express slot.
b. Please clean the golden finger.
c. The PCI Express slot is defective. Please try other slots until you find one
that works.
d. The mainboard does not have an available IRQ for the PCI Express
serial board. Enter the PC.s BIOS and make sure an IRQ setting is
available in the PCI/PnP settings.
e. The board itself might be defective. You can try another mainboard
testing this board working or not.
2. There is a blue screen when I entry operation system.
A: The possible reason is an IRQ or I/O address conflict with other PCI
Express or PCI bus adapters, such as LAN or serial boards, or with the
system BIOS. Refer to the corresponding problem in the previous FAQ for
solutions.
3. There are some exclamation marks in device manager and serial ports
can not work properly.
A: It caused by the wrong driver installing or hardware settings. Please turn off
your computer firtly and re-install hardware and software, especially
re-install the correct driver.
4. Should I enable auto flow control features?
A: Enable Auto CTS/RTS Flow Control means the CTS/RTS flow control is
controlled by hardware automatically. System will be more stable if the
function is enabled. Please make sure your serial device and cable wiring
before enabling the hardware flow control function.
31
___________________________________________________________________________________
5. How large FIFO length I should set?
A: FIFO (First-in-First-out) buffers are used to reduce the frequency of interrupt
processes for UART chips. The size of the buffer will determines the
number of times the cards need to interrupt the computer’s CPU in order to
process a string of data. With larger FIFO buffer size; there is more data
flow and less interruption to the CPU, therefore allowing the CPU to be free
to handle other more crucial tasks.
Set the Receive/Transmit Buffer to higher value will get faster performance
because the interrupts will be reduced, but the time for interrupt service
routine will become shorter. The receive buffer overflow will be easily
happened if the CPU speed is not enough to handle. If the system is not
stable, select the lower value to correct problems.
