How to use
Power down the computer and insert the adapter into an available PCIe x1 slot. Secure the card with the supplied bracket (low-profile or full-height as required). Route the two breakout cables from the internal connector to the rear of the case and mount the DB9 connectors in the appropriate openings or plate. Boot Windows, install any required drivers provided by StarTech if not automatically detected, and verify each serial port in Device Manager before connecting peripherals.
Usage recommendations
Use shielded DB9 cables where possible and configure correct COM port settings (baud rate, parity, data bits, stop bits) in the host application to match connected serial devices. Ensure the card is installed in a stable PCIe slot and avoid hot-plugging the internal breakout cables while the system is powered to prevent possible ESD damage.
