This CH384 series of multiple serial port card with PCIe interface, can be used with PCIe slot on the computer, Onboard with WCH master control chip, through used our serial card or parallel card, able to extend your computer serial or parallel port, 

which is connected to the serial or parallel port devices. Example :serial port Network, serial keyboard, RS485 communication, parallel / printer port expansion. and another serial or parallel interface devices.
