  • 1-to-8 DB9 cable keeps multi-device wiring tidy
  • PCI IRQ sharing saves motherboard interrupt resources
  • Standard PCI slot works on Windows and Linux

Eight-port RS232 expansion

This SMUGDESK PCI card adds eight independent DB9 serial ports to a desktop or industrial PC. Each port reaches a maximum of 926.1Kbps through the onboard 16C1058 controller. A bundled 1-to-8 DB9 cable keeps external wiring tidy for multiple devices. The standard PCI interface works with common Windows and Linux installations.

Industrial control and POS deployments

The card suits builders who need many legacy COM connections for automation equipment, point-of-sale terminals or monitoring hardware. IRQ sharing reduces interrupt pressure on the motherboard. It is not for systems that lack a free PCI slot or for applications that require USB, Ethernet or other modern interfaces instead of RS232.

Fits a standard PCI slot

Installation requires an available 32-bit PCI slot on the motherboard. The 1-to-8 breakout cable routes eight DB9 connectors out of a single bracket opening, freeing internal space and simplifying cable management. No auxiliary power connector is needed, so the card draws what it requires from the slot itself.

Questions about this item

What type of motherboard slot is required for the SMUGDESK 8-Port RS232 PCI Serial Card?

The card uses a standard PCI interface, so an available PCI slot on the motherboard is required for installation.

Will this card share interrupts with other PCI devices in my system?

Yes, it supports PCI IRQ sharing to save limited motherboard interrupt resources efficiently.

How can I verify each port is functioning at the rated speed after installation?

Check the device manager or serial terminal software to confirm all eight COM ports are detected and communicating at up to 926.1Kbps.
