How to use

Power off the computer and open the case. Insert the card into an available PCI Express x1 slot and secure it with the supplied bracket; replace with the low-profile bracket if installing in a slim chassis. Reassemble the case and power on the system. Install the appropriate drivers for your operating system (Windows 10 or Windows 8.1) if they do not install automatically. Connect serial devices to the external DB9 ports and configure serial parameters (baud rate, data bits, parity, stop bits) in the device manager or application software.
