How to use

Power down the PC and unplug it from the mains. Open the PC case, insert the DeLOCK 89557 into an available PCI Express slot and secure it with the bracket and screw. If installing into a Mini-PC, replace the full-height bracket with the supplied low-profile bracket. Close the case and reconnect power. Install the appropriate Windows driver if the operating system does not automatically recognize the ASIX AX99100 chipset. After driver installation, connect external serial devices to the card's ports and configure COM port settings in the operating system or application as required.

Recommendations

Use shielded serial cables for reliable connections and keep cable runs as short as practical. Confirm device baud rates and COM port settings in host software to ensure proper communication. When installing drivers, obtain them from the device manufacturer or from ASIX/DELOCK support resources to ensure compatibility.
