PCIe Combo Serial Parallel Card for Legacy I/O

This PCIe x1 expansion card adds one RS232 serial port and one IEEE 1284 parallel port to a desktop computer using the WCH382 controller. It targets users who still operate industrial equipment, older printers or specialised instruments that require native COM and LPT connections.

Low-profile bracket eases installation in compact

The board fits a standard PCIe x1 slot and ships with a low-profile bracket for slim chassis. Driver support covers 32-bit and 64-bit Windows from 2000 through 10 plus Linux; the serial UART handles 50 bps to 16 Mbps while the parallel port reaches 1.5 Mbps in SPP, PS2, EPP or ECP modes.

Verify an open PCIe x1 slot

Ensure the motherboard has a free x1 lane and that the target operating system appears in the supported list. The package includes two parallel-port brackets and a driver CD, but no cables for the serial header are supplied.

Questions about this item

How do I verify the card is working after installing it in a PCIe x1 slot?

Open Device Manager in Windows or run lspci on Linux; the WCH382 controller should appear as a multi-function device with one parallel port and two serial ports listed without error codes.

What hardware is included and what must I source separately?

The box contains the PCIe combo card, two parallel port brackets and a driver CD; cables for RS232, RS422 or RS485 devices and any parallel printer cables are not included.

Which bracket should I choose for a low-profile chassis?

Use the supplied low-profile bracket that matches the card's half-height form factor; the standard-height bracket in the package is for full-size cases only.
