TeKit NTRAC100090W PCI-E serial card

This PCI Express controller card adds two independent RS-232 ports to a desktop computer through a single PCI-E slot. It uses the WCH382L chip and targets users whose motherboards lack enough native serial headers for legacy or industrial peripherals.

Two native 9-pin COM ports with 110-230400Bps range

Each port provides a standard DB9 connector driven by its own interrupt rather than a shared virtual device. The hardware supports data rates from 110 to 230400 bits per second and complies with the PCI Express 1.0 a standard for broad slot compatibility.

Stable flow under continuous industrial use

Separate interrupt control addresses let each channel manage complex transmission control without data loss during sustained transfers. Driver support spans Windows 9X through Windows 7, plus Linux, so long-running logging or machine-control tasks remain reliable across supported operating systems.

Questions about this item

What does the 230400 Bps rate mean when the card is installed in a working system?

Each of the two ports can transfer data at up to 230400 Bps, giving a combined serial throughput well within the PCI‑Express 1.0 a link capacity.

Which PCI‑Express standard does the WCH382L card use and what does it cap in practice?

The card complies with PCI‑Express 1.0 a, so the slot provides ample bandwidth for both serial ports running at their maximum 230400 Bps rate.

What physical slot and bracket space does the NTRAC100090W need to fit?

It requires a standard PCI‑Express slot on the motherboard and occupies one low‑profile bracket opening for the two DB‑9 connectors.
