Internal Serial Adapter DeLOCK 89444

The DeLOCK 89444 is an internal serial adapter that adds one external serial (RS-232) port to a PC via a PCI Express (PCIe) slot. Equipped with a SUN2212 chipset and a 128-byte FIFO buffer, the card supports serial communication for devices such as scanners, printers and mice. A low-profile bracket is included for installation in compact or Mini-PC systems.

Advantages

The PCIe serial adapter provides reliable serial connectivity through a dedicated SUN2212 chipset and hardware FIFO buffering. It supports data transfer rates up to 0.0001152 Gbit/s and fits standard and low-profile enclosures thanks to the included bracket. Compatibility with multiple Windows 10 versions allows straightforward driver support on typical desktop and compact systems.

Suitable for

• Connecting legacy serial devices (scanners, receipt printers, industrial controllers)
• Adding a COM port to desktop PCs for point-of-sale or industrial applications
• Installing in Mini-PCs or small form-factor systems using the low-profile bracket

Usage recommendations

Use a proper RS-232 cable and confirm device settings (baud rate, parity, stop bits) match between the host system and the connected peripheral. For compact systems, verify clearance and airflow before installing the card with the low-profile bracket.
