Troubleshooting
SUNIX COM Port (COM3)
Ports (COM & LPT)
SUNIX COM Port (COM4)
Q 1. System fails to find the PCIe Industrial I/O Control Board.
Ans: It may cause by following issue:
a. The board is not properly plugged into the PCIe slot.
b. Please clean the golden finger.
c. The PCIe slot is defective. Please try other slots until you find one that works.
d. The mainboard does not have an available IRQ for the PCIe 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.
Q 2. There is a blue screen when I entry operation system.
Ans: It may cause by following issue:
a. The possible reason is an IRQ or I/O address conflict with other PCIe bus adapters,
such as LAN or serial boards, or with the system BIOS.
Refer to the corresponding problem in the previous FAQ for solutions.
b. Please check driver update from your vendor.
Q 3.
There are some exclamation marks in device manager and serial ports can not work properly.
Ans: It may cause by following issue:
a. It caused by the wrong driver installing or hardware settings.
Please turn off your computer firstly and re-install hardware and software,
especially re-install the correct driver.
b. Please update driver manually by specifying driver INF file folder.
Q 4. Should I enable auto flow control features?
Ans:
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.
Q 5. How large buffer length should I set?
Ans: B
uffers are used to reduce the frequency of interrupt processes for UART chips. The size of the buffer
will determine 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.
