Interná paralelno-sériová adaptérová karta DeLOCK 89556

The Delock Internal Parallel Serial Adapter (model 89556) is a low-profile PCI Express expansion card that adds two external RS-232 serial ports and one external parallel (IEEE 1284) port to a desktop or Mini-PC. Based on the ASIX AX99100 chipset and offering 256‑byte FIFO buffering, the card is intended for connecting legacy peripherals such as printers, scanners and serial devices in space-constrained systems.

Advantages

This PCIe card provides a compact, low-profile solution to add serial and parallel interfaces without requiring a full-height slot. The ASIX AX99100 chipset with 256 B FIFO improves data handling for connected devices. Included low-profile brackets allow installation in Mini-PCs while maintaining compatibility with common Windows operating systems, and the green PCB design fits discreetly into small chassis.

How to use

Power down the PC and unplug it from the mains. Open the chassis and insert the adapter into an available PCIe slot. Secure the card using the appropriate bracket (standard or low-profile) depending on your chassis. Connect external devices to the two serial DB9 ports and the parallel port on the rear panel. Close the chassis, reconnect power and boot the system. Install any required drivers supported by your Windows version to enable full functionality.

Recommendations

Use shielded serial cables for reliable RS-232 communication in electrically noisy environments and verify driver compatibility with your specific Windows edition before deployment. Ensure the card is seated firmly in the PCIe slot and that low-profile bracket is correctly attached for small form-factor cases.
