InLine PCI Multi I/O Controller Card 4 DB9 Serial Ports

This InLine PCI Multi I/O Controller Card provides four DB9 serial ports on a standard PCI interface, based on the MosChip MCS9865 chipset. It enables addition of serial and parallel connectivity to PCs whose motherboards no longer include these ports, supporting reliable wired connections for serial devices with a maximum data transfer rate of 115.2 Mbit/s. Drivers referenced in the supplied operating instructions point to an external website that is not affiliated with the manufacturer and is being misused for phishing; do not use that site.

Advantages

The PCI Multi I/O card supports up to four DB9 serial ports and uses a modern MosChip PCI peripheral controller for broad compatibility with PCI-capable systems. It delivers stable data transfer up to 115.2 Mbit/s and is suitable for continuous operation in industrial automation and legacy-device connectivity. The card installs in a standard PCI slot and restores serial/parallel ports on systems that lack them.
