TeKit Dual RS-232 PCI Serial Card

The TeKit NTRAC100088W adds two DB9 serial ports to a desktop computer through a standard 32-bit PCI slot. It uses a 16C550 UART with 16-byte transmit and receive FIFO buffers and supports transfer rates up to 1 Mbyte per second. The card works with Windows 98SE, Me, 2000, XP, NT 4.0, Vista, Win 7 and Linux. A driver CD is included in the package.

Who this suits and who should look elsewhere

This card suits technicians maintaining industrial equipment, point-of-sale systems or legacy peripherals that still require RS-232 connectivity. It is not for builders whose motherboards lack a 32-bit PCI slot or who need more than two serial ports. Buyers wanting USB or PCI Express native interfaces should look at a different product.

The deciding specification

The card installs into a 32-bit PCI slot and provides two DB9 connectors driven by a 16C550 UART. If your system has an available 32-bit PCI slot and you need exactly two RS-232 ports this is the right part.

Questions about this item

Does my motherboard need a 32-bit PCI slot for this card?

Yes, the card fits a 32-bit PCI slot and is compatible with PCI Rev 2.1.

Can I run this card on the same bus as legacy PCI devices?

The card supports PCI IRQ sharing so it can coexist with older PCI hardware on the same bus.

How do I verify the 16C550 UART is active after installation?

Check Device Manager for two new COM ports; each should show a 16-byte FIFO and support transfer rates up to 1 Mbytes/sec.
