ASIX Electronics Corporation Notice USB to LAN products 
Dear Customer:

If you got some problems on ASIX USB to LAN products, please download the How to identify authentic ASIX USB to LAN Products document to double check if your USB to LAN device includes an Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR THOSE NON-AUTHENTIC ASIX PRODUCTS.

  Yes, I understand.

 MCS9835 -- PCI to Dual Serial and Single Parallel Controller

The MCS9835CV-BA is a PCI based single function I/O Adapter. It has two 16C450/16C550 compatible UART channels and one IEEE 1284 compliant parallel port.

The MCS9835CV-BA has 32-Byte transmit and receive FIFO for each UART channel. MCS8935CV-BA performs serial-to-parallel conversions on data received from a Serial device, and parallel-to-serial conversions on data received from its CPU.

Parallel Port interface in MCS9835CV-BA is an IEEE 1284 compliant SPP / PS2 / EPP / ECP Parallel Port that fully supports Centronics interface.

The MCS9835CV-BA is ideally suited for PC applications, such as Add-On COM ports and Parallel Ports. It is available in 128-Pin QFP package & fabricated using an advanced submicron CMOS process to achieve low power drain and high-speed requirements.

MCS9835CV-BA is designed to be pin compatible with previous version of MCS9835CV. Existing designs of MCS9835 can be migrated to MCS9835CV-BA without any modification to system design. Software compatibility is also maintained between MCS9835 to MCS9835CV-BA.
