    Q0001: Is AX78140 IC pin-to-pin compatible to MCS7840 IC?
    A0001: Yes, AX78140 IC is pin-to-pin compatible to MCS7840 IC.

    Q0002: Where can I obtain the latest AX78140 datasheet, reference schematic and other hardware design archives?
    A0002: Please register MyASIX membership (http://www.asix.com.tw/RegLogin.php?mod=thisis) and then download the latest AX78140 datasheet, reference schematic, PCB layout guide, etc. from AX78140 Product web page (http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=257;74;109&PLine=74) directly.

    Q0003: Can ASIX help me to review my own AX78140 schematic and PCB layout?
    A0003: Yes, please deliver your own AX78140 schematic and PCB layout files to ASIX’s Support (support@asix.com.tw) for further review before making your own AX78140 PCB board.

    Q0004: Is the I2C EEPROM required for AX78140 4S/2S1P applications?
    A0004: The I2C EEPROM is required for AX78140 2S1P applications and is optional for AX78140 4S applications.

    Q0005: How to program AX78140 I2C EEPROM in-circuit?
    A0005: The AX78140 supports a Windows EEPROM Utility to program the I2C EEPROM in-circuit.

    Q0006: Does ASIX support RS-232/RS-485 transceivers solutions?
    A0006: 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.

    Q0007: Does AX78140 USB to parallel port support ECP/EPP modes?
    A0007: No, AX78140 USB to parallel port doesn’t support ECP/EPP modes.

    Q0008: Can AX78140 install the original MCS7840 drivers directly?
    A0008: Yes, you should be able to install the original MCS7840/MCS7820 drivers on AX78140 applications directly. If you have any problems, please download the latest AX781x0 drivers from AX78140 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=257) instead. The latest AX781x0 drivers supports all AX78140/AX78120/MCS7840/MCS7820/MCS7810 applications.

    Q0009: Where can I obtain the latest AX78140 drivers?
    A0009: Please visit AX78140 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=257) to download proper drivers for your AX78140 target applications.

    Q0010: How to change the COM port number of AX78140?
    A0010: Yes, we can change the COM port number by using a drop down list located in AX78140 Windows COM Port Properties. To change the COM port number, go to "COM Port Properties => Features => COM Port Number".

    Q0011: How to change the LPT port number of AX78140?
    A0011: Yes, we can change the LPT port number by using a drop down list located in AX78140 Windows LPT Port Properties. To change the LPT port number, go to "LPT Port Properties => Features => LPT Port Number".
