___________________________________________________________________________________ 3. Driver Installation ______________________________________________ After installing the RS-232 PCI Express Multi-Port Communication Board in your system successfully, please follow the step by step software installation guide to confirm how to install appropriate driver and configure the serial port settings.
___________________________________________________________________________________ Windows Driver Installation Please refer to following instructions to install the driver for the first time under Windows operation system. You will need to plug the board in an available PCI Express slot first, before installing the driver. (1) After the board is physically installed and the PC boots up, system will detect the PCI Express Serial card and prompt for driver installation wizard, please choose cancel.
___________________________________________________________________________________ (3) Please select the product interface you bought, such as PCI Express. (4) Please select the O.S. version you are using, such as Windows Vista. Then system will process the driver installation step automatically.
___________________________________________________________________________________ (5) Please select driver language for your operation system. (6) Click “Next” to continue driver installation steps.
___________________________________________________________________________________ (7) Click “Install” to continue driver installation steps. (8) System will install driver automatically. It takes about one minute.
___________________________________________________________________________________ (9) Click “Finish” to end installation steps.
___________________________________________________________________________________ Windows Driver Uninstallation Please refer to following instructions uninstall Multi-I/O card driver. (1) Click on the “Programs and Features” tab in the Windows Control Panel. Start > Controller Panel > Programs and Features (2) Entry Uninstall or change a program page, and double click “Windows Driver Package – SUNIX Co., Ltd SUNIX Multi-I/O Controller” to process driver uninstallation procedure.
___________________________________________________________________________________ Linux Driver Installation This installation guide describes the procedures to install the PCI serial board in Linux kernel 2.4.x and 2.6.x. Please refer to “snx_Vx.x.x.x.tar.gz” for driver installation detail in CD Driver (Linux folder) directory. : \ PCI_IO \ 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.tar.gz".
___________________________________________________________________________________ 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. Each parallel port has two device node which is name "lp?" and "parport?". This step will backup lp2~lp3 and parport2~parport3 to lp?.bak and parport?.bak in /dev for your system first.
___________________________________________________________________________________ Verify Installation You can use Windows “Device Manager” to verify proper installation. (1) Click on the “Programs and Features” tab in the Windows Control Panel. Start > Controller Panel > Device Manager (2) In the Device Manager window, you should see this board under Multifunction adapters (4-port RS-232 Serial Card in this example). You should also see SUNIX COM port under Ports (COM & LPT).
___________________________________________________________________________________ 4. Port Configuration ______________________________________________ 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.
___________________________________________________________________________________ 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.
___________________________________________________________________________________ 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.
___________________________________________________________________________________ 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.
___________________________________________________________________________________ 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.
___________________________________________________________________________________ 5. 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 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.
___________________________________________________________________________________ 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.
