PCI-E 2S1P Serial-Parallel Combination Control Card RS-232

Detailed Information About The Product:

Name：PCI-E 2S1P Serial-Parallel Combination Control Card RS-232 + LPT Print Port Expansion Card CH382L for Printer PC
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.
Asynchronous serial port provides independent 256-byte FIFO buffer for receiving and sending, supports communication baud rate up to 8Mbps, 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.
A two-wire serial host interface is provided, and serial EEPROM devices like 24C0X can be connected to store non-volatile data.
The device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board can be set in the EEPROM device.

Serial port:
Two fully independent asynchronous serial ports, compatible with 16C550, 16C552, 16C554 and 16C750 and enhanced.
Supports 5, 6, 7 or 8 data bits and 1 or 2 stop bits.
Support odd, even, no check, blank 0, mark 1 and other check methods.
Programmable communication baud rate, supports 115200bps and communication baud rate up to 8Mbps.
Built-in 256-byte FIFO first-in-first-out buffer, supports 4 FIFO trigger levels.
Support MODEM modem signals CTS, DSR, RI, DCD, DTR, RTS, which can be converted to RS232 level.
Support hardware flow control signals CTS and RTS automatic handshake and automatic transmission rate control, compatible with TL16C550C.
Support serial frame error detection, support Break line interval detection.
Supports full-duplex and half-duplex serial communication.
parallel port:
Support SPP, Nibble, Byte, PS/2, EPP, ECP and other IEEE1284 parallel/printer working modes.
It supports two-way data transmission, and supports a transmission speed of up to 1M bytes per second.
