How to use

To install the card, power down your computer, unplug it from the wall outlet, and open the system case. Insert the card firmly into an available PCI slot, secure the bracket to the chassis, and connect the included octopus cable to the card. Close the case, power on the system, and install the appropriate drivers for your Windows operating system to begin utilizing the serial ports for your communication devices.

What to consider before purchase

• Verify that your computer motherboard features an available PCI expansion slot.
• Check your operating system version for driver compatibility.
• Determine whether you need standard profile or low-profile bracket installation.

Usage recommendations

Always ensure the computer system is completely powered off and disconnected from the power source before installing or removing the internal interface card to prevent electrostatic discharge damage.
