Eight RS232 ports from one PCIe slot
This industrial expansion card converts a single PCIe slot into eight independent DB9 RS232 serial ports. Each port supports a maximum 921.6Kbps baud rate and includes a built-in FIFO buffer for steady data transmission. It is designed for connecting multiple PLCs, cash registers, serial scanners and industrial monitoring equipment.
Dual brackets for standard and SFF chassis
The card ships with both a regular bracket and a low-profile bracket to fit standard tower cases and small form factor or 2U chassis. It suits builders adding legacy serial connectivity to modern systems running mainstream Windows or Linux distributions. It does not suit users who need USB, parallel or other non-RS232 interfaces, or those whose chassis cannot accommodate a PCIe add-in card.
Verify PCIe slot and OS driver support
Before ordering, confirm your motherboard has an available PCIe slot and that your specific Windows or Linux version is supported by the supplied driver. Check that your serial cables and connected devices use DB9 connectors and RS232 signalling. Ensure the chosen bracket matches your case form factor for secure mounting.

Questions about this item
My motherboard only has a PCIe x1 slot free — will the card fit and run in that slot?
The card uses a PCIe interface and fits standard and low-profile brackets, so it installs in any open PCIe slot including x1.
I keep several older RS232 PLCs and barcode scanners — does each of the eight ports operate independently for those devices?
Yes, the card converts one PCIe slot into eight independent DB9 RS232 ports, each with its own FIFO buffer for steady data transmission.
After installing the driver on Windows, how can I confirm all eight COM ports are recognised and running at the rated 921.6 Kbps?
Open Device Manager, expand Ports (COM & LPT), verify eight new COM ports appear, then check each port’s advanced settings to confirm the 921.6 Kbps baud rate is selectable.
