1 LF719KB Quick Installation Guide V0.1 Initial Draft Thank you for selecting the Axxon LF719KB 2S1P adapter for the PCI Express expansion slot. This model represents the industry s most advanced model to offer 2 High Speed (1 Megabaud) 16C950 UART based serial ports with the RS232 interface + 1 of EPP/ECP mode compatible parallel port. This document offers a quick installation procedure for this product model. At anytime please feel free to contact us with any questions you may have. Our support staff may be reached via phone: Toll-free (US/Canada): (10 AM to 6 PM EST M-F) International callers: Fax: support@softio.com Installation Procedure 1. Turn off the power to your computer system and remove the computer cover to permit the installation of this circuit board. 2. Find an open PCI Express expansion slot and remove the filler mounting bracket for that expansion slot. The LF719KB is compatible with x1, x4, x8, x16 lane expansion slots so ultimately the choice is yours for which slot is convenient to use for this product. No additional user benefits are gained by using a higher lane count slot for this model. That is, for example using a x4 lane slot over a x1 lane slot. 3. Gently but firmly insert the card into your PCI Express (PCIe) expansion slot and attach the mounting screw to fasten the mounting bracket to your computer case. 4. Power up your computer system to continue the Plug & Play installation of the LF719KB. In most installations, you will be presented with the Plug & Play detection of the LF719KB within Windows and/or Linux. For Windows, please point to the LF719KB folder on the device driver CD provided with this adapter. At the end of this document is a URL for the current device driver suite. Please download and unzip to apply the current device driver set for your installation. For each and every instance of a device driver request, please continue to point to the same LF719KB folder. Upon a proper installation, you will be presented with 2 additional serial ports (communication ports) and an additional parallel port for your use. For Win XP / 2K / 2003 you may use the Control Panel -> Hardware -> Device Manager - > Ports -> COMx and alter the COM label to suit using the Advanced button located within the Port Settings property tab.

2 5. In most flavours of Linux, Kudzu will auto-detect the presence of our adapter for both the serial and parallel ports. In the event that the serial port is not detected, a simple manual method may be applied to map the ports manually. Please contact our technical support staff if a manual assignment is not practical to your Linux installation. We have alternate means to permit a PnP detection of our adapters for older Linux kernels. 6. The LF719KB consists of 2 high-speed RS232 serial ports, which are supported in Windows, Linux, OS/2, and QNX. Respectively, the single parallel port is supported in Windows, Linux and DOS. For DOS support, please run the 719KBDOS.COM program by placing this software within your autoexec.bat file.

3 Here is the method to manually associate the serial driver to the LF719KB card for Linux: 1) Go to terminal / console. 2) From the /proc/pci file, it is possible to find the PCI card's I/O port address and IRQ. You can also use "lspci -vv" (Please note these are 2 of the letter v as in Victor and NOT w as in William ) to display all PCI products in your system. We are interested in the Vendor ID: 1415 and Device ID: 9521 and the IRQ value for this card. The above 3 pieces relate to our model LF719KB's PCI UART. For example, if your listing is as follows: I/O at 0xc000 base serial port address (Base Address 0 or BAR0) [size=8] I/O at 0xc008 base serial port address (Base Address 1 or BAR1) [size=8] 1st serial port 0xc000 2nd serial port 0xc008 BAR0 = Base Address Register # 0 holds the I/O Address for our 1 st UART controller. BAR1 = Base Address Register # 1 holds the I/O Address for our 2nd UART controller. Assuming that ttys4 is free AND irq is 11 (from the output of the lspci command) for your card. setserial /dev/ttys4 port 0xc000 uart 16550A irq 11 baud_base Assuming that ttys5 is free AND irq is 11 (from the output of the lspci command) for your card. setserial /dev/ttys5 port 0xc008 uart 16550A irq 11 baud_base Confirm the manually created settings for ttys4 or ttys5 using the following commands: setserial /dev/ttys4 -a setserial /dev/ttys5 -a The above syntax will define the mapping for a style UART. The Axxon card is based on the enhanced UART so optionally you may wish to enhance the Linux based device driver support for the 16C950 UART as follows: setserial /dev/ttys4 port 0xc000 uart irq 11 baud_base setserial /dev/ttys5 port 0xc008 uart irq 11 baud_base Comment: If you wish to apply the serial ports under Linux at data rates upto 921k then please contact us for a configuration program to select the CLK/1 setting on the adaptercard. Using this utility, you will be able to clock the Mhz at which point the setserial commands will change to: setserial /dev/ttys4 port 0xc000 uart irq 11 baud_base setserial /dev/ttys5 port 0xc008 uart irq 11 baud_base Most current Linux distributions will Plug & Play auto-detect the adaptercard. It is important to note that in the autodetection, there is an obligation for the adaptercard to be configured to use the CLK/1 setting. Otherwise, you will be required to manually apply the setserial commands to synchronize the provided hardware clock value as follows:

4 If the Clock = CLK/8 then apply these commands: setserial /dev/ttys4 port 0xc000 uart irq 11 baud_base setserial /dev/ttys5 port 0xc008 uart irq 11 baud_base If the Clock = CLK/1 then apply these commands: setserial /dev/ttys4 port 0xc000 uart irq 11 baud_base setserial /dev/ttys5 port 0xc008 uart irq 11 baud_base Re-confirm the manually created settings for ttys4 or ttys5 using the following commands: setserial /dev/ttys4 -a setserial /dev/ttys5 -a The DMESG log will list these 2 add-on serial + 1 add-on parallel ports during the boot process of Linux. You can verify the board's operation using an external modem and running: minicom -s ; then select /dev/ttys4 (or ttys?? that you created) and then type in a variety of Hayes commands including: ATZ, ATi6 or ATDT ; to dial, etc. The parallel port component will be listed as: /dev/lp0 if this adapter card is the only parallel port in the system. /dev/lp1 if motherboard LPT1 exists and this adapter card is an add-on parallel port in the system. /dev/lp2 if motherboard LPT1 & LPT2 exist and this adapter card is an add-on parallel port in the system. The Parallel Port function on the LF652KB is Plug & Play supported in most Linux distributions. If your Linux OS does not auto detect the parallel port, please contact Axxon with your kernel / Linux version information for additional assistance. Q: LF719KB is installed but Linux does not display the add-on serial ports in my distribution? This is a common report from clients using 2.5.x and 2.6.x kernels. This issue is related to the Linux distribution not supporting add-on serial adaptercards as a default. That is, only the legacy serial ports are detected and supported unless additional boot command line parameters are applied.

5 Here is a discussion and solution on this topic: You don't have to recompile the kernel, just edit the file /boot/grub/grub.conf and add "8250.nr_uarts=32" to the end of kernel line. This a example from a FC5 grub.conf file: kernel /boot/vmlinuz fc5 ro root=label=/ And then you add the 8250.nr_uarts=32 statement: kernel /boot/vmlinuz fc5 ro root=label=/ 8250.nr_uarts=32

C:\axxon). Boot your system to allow for a Plug & Play detection of the adapter card and for each request for a device driver please point to the temp folder (ie. C:\axxon). Most of Axxon s designs consist of multi-functions and likewise you will be prompted for the device driver for each and every function. The driver is not signed so permit installation regardless of the Microsoft warning of the missing signature. This release of the device driver is suitable for Windows XP (32 / 64 bit), XP / XP Pro / 2000 / 2003 (32 / 64 bit) & NT4. For Windows NT4 installs, run the INSTALL_SERIAL.EXE and/or INSTALL_PARALLEL.EXE for the respective model of our circuit board. Current operating systems will Plug & Play detect our product line and prompt for a device driver. Beta Vista device drivers are available upon request.
