  •  
     
    Q0001: Where can I obtain the latest AX99100 datasheet, reference schematic and other hardware design archives?
    A0001: Please register MyASIX membership (http://www.asix.com.tw/RegLogin.php?mod=thisis) and then download the latest AX99100 datasheet, reference schematic, PCB layout guide, etc. from AX99100 Product web page (http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=256;74;110&PLine=74) directly.

    Q0002: Can ASIX help me to review my own AX99100 schematic and PCB layout?
    A0002: Yes, please deliver your own AX99100 schematic and PCB layout files to ASIX’s Support (support@asix.com.tw) for further review before making your own AX99100 PCB board.

    Q0003: Is the I2C EEPROM required for AX99100 serial/parallel/SPI applications?
    A0003: The I2C EEPROM is optional for some of AX99100 serial/parallel/SPI applications.

    Q0004: Is the I2C EEPROM required for AX99100 Local Bus/ISA-Like applications?
    A0004: Yes, the I2C EEPROM is required for AX99100 Local Bus/ISA-Like applications. Please contact ASIX Sales (Sales@asix.com.tw) to further support.

    Q0005: How to program AX99100 I2C EEPROM in-circuit?
    A0005: The AX99100 supports a Windows EEPROM Utility to program the I2C EEPROM in-circuit.

    Q0006: Can AX99100 support full ISA interface?
    A0006: No, AX99100 only supports 10-bit address bus (A[9:0]) for ISA-Like applications so AX99100 does not support full ISA interface (with 24-bit address bus). Please contact ASIX Sales (Sales@asix.com.tw) to further support.

    Q0007: Does ASIX support RS-232/RS-485 transceivers solutions?
    A0007: Yes, ASIX also supports different RS-232/RS-485 transceivers solutions (i.e. Zywyn RS-232/RS-485 transceivers products). Please visit ASIX I/O Connectivity RS-232/RS-485 Transceivers Products Web page (http://www.asix.com.tw/products.php?op=ProductList&PLine=74&PSeries=122) for more details.

    Q0008: Where can I obtain the latest AX99100 PCIe to Serial/Parallel drivers?
    A0008: Please visit AX99100 Driver Download web pages (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=256) to download proper drivers for typical AX99100 PCIe to Serial/Parallel target applications.

    Q0009: Where can I obtain AX99100 PCIe to Local Bus/ISA-Like/SPI drivers and demo tools?
    A0009: For AX99100 PCIe to Local Bus/ISA-Like/SPI applications, ASIX provides AX99100 PCIe to Local Bus/SPI Windows/Linux drivers and demo tools for customers to evaluate the basic functionalities of AX99100 PCIe to Local Bus + Async SRAM Demo Board and AX99100 PCIe to SPI demo board. ASIX can also provide the source codes for customers’ reference if necessary. Please contact ASIX Sales (Sales@asix.com.tw) for further support.

    Q0010: How to change the COM port number of AX99100?
    A0010: Yes, we can change the COM port number by using a drop down list located in AX99100 Windows COM Port Properties. To change the COM port number, go to "COM Port Properties => Port Settings => Change Port Number => COM Port Number".

    Q0011: How to change the LPT port number of AX99100?
    A0011: Yes, we can change the LPT port number by using a drop down list located in AX99100 Windows LPT Port Properties. To change the LPT port number, go to "LPT Port Properties => Port Settings => LPT Port Number".

    Q0012: Is it possible to manually change the IRQ of AX99100 Parallel/Serial ports?
    A0012: It is not possible to manually change IRQ setting of all PCIe devices in any operating systems because the IRQ used by the device is assigned by the PCIe system and cannot be changed. Usually the only way to change the IRQ of a PCIe device is to move it to a different PCIe slot. Each slot is usually assigned a different IRQ, although this is not always true. Each system may handle the assignment of IRQs differently.

    Q0013: Is it possible to remap the I/O addresses of AX99100 Parallel/Serial ports to Legacy I/O address values?
    A0013: In order to be compatible with some legacy software, some users might need to remap the assigned I/O addresses of AX99100 Parallel/Serial ports to Legacy (ISA type) I/O address (such as 378h, 3F8h, etc.). It is possible on DOS and Windows 95/98/ME operating systems but impossible on Windows NT/2000/XP/Vista/7/8 operating systems because the Remap I/O Address feature is only supported on DOS and Windows 95/98/ME operating systems but is not supported on Windows NT/2000/XP/Vista/7/8.x/10 operating systems. As the newer Windows systems maintain a much tighter control over the I/O devices and prevent any Re-Mapping I/O Address operation at device driver level. When the Re-Mapping I/O Address is not permitted, the device must use the I/O Addresses assigned by the PCIe system at Boot-Up. If the software application expects the Parallel/Serial ports to use Legacy I/O address resources, it will not be possible to make it work with the Parallel/Serial ports of PCIe based devices on Windows NT/2000/XP/Vista/7/8.x/10 platforms. On DOS platform, AX99100 can remap the I/O addresses of the Parallel/Serial ports to desired values by running AX99100 DOS utility. However, on Windows 95/98/ME platforms, you can only remap the I/O addresses of the Serial ports (but not Parallel port).
