Εσωτερικός αντάπτορας RS-232 DeLOCK 89948

The DeLOCK 89948 is an internal RS-232 adapter that provides one external serial RS-232 port via a PCIe host interface. Equipped with the ASIX AX99100 chipset and a 256 B FIFO buffer, the card supports data bit lengths from 5 to 9 and is compatible with Windows 10, 8.1 and 7. Its compact dimensions (60 × 64 × 16 mm) and included low-profile bracket make it suitable for standard PCs and Mini-PC installations.

Advantages

This PCI Express card offers a reliable single RS-232 port with hardware-level buffering (256 B FIFO) to improve data handling and reduce CPU load. The ASIX AX99100 chipset ensures broad compatibility and stable serial communication. The adapter's internal PCIe design and supplied low-profile bracket provide flexible mounting options for both full-size and small form-factor systems. Its support for a range of data bit lengths (5–9) allows use with various legacy and industrial devices.

Suitable for

• Connecting barcode scanners and POS systems
• Interfacing with protocol converters and industrial controllers
• Connecting infrared modules and IoT devices with RS-232
• Adding a serial port to Mini-PCs and compact workstations

How to use

Install the DeLOCK 89948 into an available PCIe slot on the motherboard, securing it with the full-height or the supplied low-profile bracket as required by your chassis. Connect the external RS-232 device to the card's serial port using a compatible serial cable. Install the appropriate drivers for the ASIX AX99100 chipset on a supported Windows system if the operating system does not automatically provide them. After driver installation, verify serial port settings (baud rate, parity, stop bits, data bits) in your operating system or application to match the connected device.

Recommendations

For stable operation, use shielded serial cables for longer runs and configure UART settings to match the connected device. Ensure the system is powered down when installing the card, and check for the latest ASIX drivers from the manufacturer if communication issues occur.
