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.

 MCS9901 -- PCIe to Dual Serial and Single Parallel Controller New!

MCS9901CV-CC is a single lane multifunction PCI express to I/O controller. It supports two serial ports, one parallel port and six GPIO's. MCS9901CV-CC also provides an option for peripheral expansion through proprietary Cascade interface. The generic cascade interface allows interconnecting with similar chips like MCS9900, MCS9950 to expand the peripheral ports. The serial ports are compatible with RS232, RS422 & RS485 standards and supports throughput from 50bps to 16Mbps. Parallel Port is compatible with IEEE 1284 and supports Nibble, Byte, SPP, ECP, and EPP modes. All the GPIO pins are programmable and can be used as Input or Output. An I簡C interface is provided to configure MCS9901CV-CC device options through an external EEPROM.
