Two RS-232 ports on a PCIe x1 card

This EN-Labs adapter adds two standard DB9 male serial ports to a desktop PC through a single-lane PCI Express 1.0a slot. The board uses the WCH CH382L chipset and ships with a full-profile bracket for typical tower chassis. It is intended for users who need to connect legacy serial equipment such as industrial controllers, barcode scanners or older networking gear.

Suits technicians and hobbyists with free x1 slots

The card works with Windows 98 through Windows 8, Server 2003 and 2008, and Linux, covering a wide range of older and current operating systems. Builders whose systems lack an available PCIe x1 slot, or who require USB, parallel or other legacy interfaces instead of RS-232, will not be able to use this product.

Data rate configurable from 110 to 230400 bps

Each port supports asynchronous speeds selectable across the full 110–230400 bps range, with the chipset rated for stable operation up to 115200 bps. This flexibility lets the card match the exact baud-rate requirements of diverse serial devices without additional configuration hardware.

Questions about this item

What PCI-Express lane width and revision does the card use, and what serial speed does that allow?

It plugs into a single x1 lane compliant with PCI-Express revision 1.0a and drives both DB9 ports at up to 230400bps.

Which bracket style ships with the card, and what slot height does it need?

A full-profile bracket is included, so the card requires a standard-height rear opening in the chassis.

How is the card installed, and what step is often missed?

Insert it into a free x1 or wider PCIe slot, secure the full-profile bracket screw, then install the WCH CH382L driver for Windows 98 through Server 2008 or Linux before the ports will appear.
