Dual-Port Serial PCIe Card for Industrial
The StarTech 2S232422485-PC-CARD adds two RS232, RS422 and RS485 serial ports through a single PCI Express slot. It targets engineers and integrators who need to link legacy industrial equipment, point-of-sale hardware or scientific instruments to modern PCs. The board provides a direct hardware path for serial communication without relying on USB-to-serial converters.
Passive Cooling and Low Power Consumption
The card operates without a fan, drawing power solely from the PCIe bus for silent running in noise-sensitive environments. Level-4 ESD protection guards each port against 15 kV air-gap and contact discharge events. A wide operating temperature and humidity range supports continuous duty in industrial cabinets or server rooms.
Low-Profile Brackets and DB9 Connectors
Two standard DB9 male connectors face the rear bracket for secure screw-on cabling. Both full-height and low-profile brackets are included to fit compact or full-size chassis. RoHS and TAA compliance confirms the assembly meets regulated procurement requirements for government and enterprise projects.

Questions about this item
How do I install the 2S232422485-PC-CARD and which bracket step is often missed?
Insert the card into an open PCIe slot, secure it, then swap the standard bracket for the included low-profile bracket if your chassis requires it; many builders forget the bracket swap and cannot close the case.
What maintenance or replacement will the dual-port serial card need over time?
The on-board ESD protection rated at 15KV air-gap and contact discharge is sacrificial; after repeated surge events the protection degrades and the card should be replaced to keep connected equipment safe.
What limit appears first when the card runs at sustained 921.6 Kbps throughput?
Continuous maximum-rate traffic can push the controller into its thermal envelope, causing the driver to throttle the UART clock and reduce effective throughput until the card cools.
