การ์ด PCI-Express ( PCI-E ) To 2 Serial Port 1 Parallel Port Control Card RS232 LPT Print Converter PCIe DB9 DB25

CH382 is a dual serial port and printer port chip for PCI-Express bus, including two 16C550 or 16C750

compatible asynchronous serial ports and an EPP/ECP enhanced bidirectional parallel port.

The asynchronous serial port provides a 256-byte FIFO buffer with independent transceivers,

supports a communication baud rate of up to 8Mbps, and can be used for PCI-E

Bus RS232 serial port expansion, PCI-E high-speed serial port with automatic hardware rate control,

serial port networking, RS485 communication, parallel port/print port expansion, etc.

-The same chip can be configured as dual serial ports, single parallel port/printer port, dual serial ports plus parallel port/printer port of PCI-E bus.

-Provides a two-wire serial host interface, which can be connected to serial EEPROM devices like 24C0X to store non-volatile data.

-You can set the device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board in the EEPROM device.
