PCIe Multi-I/O card use the chip of WCH384L, It supports the maximum rate of 2-Mbps and it can be used for PCIe bus DB25+DB9 Serial Parallel Combo expansion
CH384
PCI-Express based Quad UARTs and printer port chip
Overview
CH384 is a PCI-Express based Quad-channel high performance UART with EPP/ECP enhanced bi-directional parallel controller. Each UART is compatible with 16C550 or 16C750. It can be expanded to another 24 serial ports by adding CH438 chips. The UART contains independently transmit and receive 256 bytes FIFO buffer. Supports IrDA infrared encode and decode, supports communication baud rate up to 8Mbps. It can be used for RS232 serial expansion, PCIe high-speed serial with automatic hardware speed control, serial networking, parallel/ printer port expansion etc.
- Can be configured as quad-channel UARTs with printer/ parallel port or quad-channel UARTs with extended UART based on PCIe.
- Provide two-wire serial master interface, can hang serial EEPROM similar with 24C0X to store data which is not easily missing.
- Driver supports Windows 98/ME/2000/XP/Vista/7/8/8.1/10/SERVER 2003/2008/2012/2016 and Linux.
