Two-Port PCIe RS232 Adapter

This expansion card adds two RS-232 serial ports to a desktop or server through a single PCI Express x1 lane. It uses a WCH382 controller and presents a standard 16C550-compatible UART with 256-byte transmit and receive FIFOs. The board operates at a 2.5Gb/s full-duplex link rate and supports data signalling up to 250k per second. Drivers are supplied for Windows 2000 through 8, Linux, DOS and iOS.

For Legacy Serial Integration

The card suits engineers, technicians and IT staff who need to connect industrial equipment, point-of-sale hardware, medical instruments or older networking gear that still relies on RS-232 signalling. It is not intended for users who require USB, parallel or proprietary industrial bus interfaces, nor for builds that lack a free PCI Express x1 slot. Buyers needing more than two serial channels should consider a different solution.

Build Integration Notes

Installation requires one available PCI Express x1 slot and the low-profile baffle included in the package. The adapter draws power directly from the slot and ships with a short internal cable assembly measuring approximately 5 inches. Its compact footprint of roughly 12 by 8.5 by 2 centimetres and 49-gram weight leave ample clearance in tight chassis, freeing rear-panel space for other I/O.

Questions about this item

My PC has a free PCI-Express x1 slot; is that the only hardware I need to add this card?

Yes, the card requires one available PCI-Express x1 slot and includes a low-profile baffle for smaller cases.

Will the WCH382 chip work with legacy software that expects a standard 16c550 UART and 256-byte FIFO?

The chip is compatible with the standard 16c550 UART and provides 256-byte transmit and receive FIFOs for legacy software.

After installing the card, how can I confirm the two RS-232 ports are operating at up to 250k bit/s?

Check Device Manager for two new COM ports, then run a serial loopback test at 250k bit/s on each port.
