Internal Serial Adapter DeLOCK 89557

The Internal Serial Adapter DeLOCK 89557 is a PCIe expansion card that adds four external RS-232 serial ports to a PC. Built with the ASIX AX99100 chipset and a low-profile form factor, the card supports connection of devices such as scanners, printers and serial mice and can be fitted into standard and mini cases using the supplied low-profile bracket. It is suitable for systems that require additional serial communication interfaces and is compatible with various Windows operating systems.

Advantages

The adapter provides four external serial ports on a single PCI Express slot, uses the ASIX AX99100 chipset for reliable serial communication and includes a low-profile bracket for installation in Mini-PCs. Its internal design keeps external connectors tidy while expanding legacy device support.

Suitable for

• Connecting scanners and receipt printers
• Attaching serial mice and barcode readers
• Industrial or legacy equipment that uses RS-232 interfaces
• Systems with limited expansion space (mini or small form factor PCs)

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.
