How to use

Install the card into an available 32-bit PCI slot on the motherboard, secure the bracket and connect the external RS-232 device to the DB9 male connector. If installing in a compact case, replace the full-height bracket with the included low profile bracket before mounting. After hardware installation, boot the system and install any necessary drivers for your operating system (the product is compatible with Windows 10, 8.1 and 7). Verify the COM port appears in the device manager and configure serial parameters (baud rate, parity, data bits, stop bits) according to the connected device's requirements.

Recommendations

For stable serial communication, use shielded RS-232 cables and ensure proper grounding of connected equipment. Avoid exposing the card to temperatures or humidity outside the specified ranges and handle the board using anti-static precautions during installation.
