How to use

Turn off the PC and unplug it from the mains. Open the computer case, insert the DeLOCK 89444 into an available PCIe slot and secure it with the included full-height or low-profile bracket as required. Close the case, reconnect power and boot the system. Install the appropriate drivers for your Windows 10 version if they are not automatically detected, then connect your serial device to the external serial port.
