Internal Mini PCIe interface adapter DELOCK 95279 — Serial host, Mini PCIe output, RS-232 support, 460.8 Kbit/s, FIFO 256 B, 30×51×10 mm

DELOCK 95279 is an internal Mini PCIe interface adapter that provides system expansion by exposing four serial and one parallel connection through a Mini PCIe slot bracket. The adapter presents a serial (RS‑232) host interface with a maximum baud rate of 460.8 Kbit/s and an internal FIFO buffer of 256 bytes. It supports configurable data bits (5, 6, 7, 8) and is built on a compact PCB measuring 30 × 51 × 10 mm with a component finish in black, gold and green.

Advantages

The adapter enables integration of legacy serial and parallel peripherals into systems with a Mini PCIe slot without requiring additional external converters. Its internal design preserves chassis space and the 256‑byte FIFO reduces CPU overhead during burst transfers. Configurable data bit settings and support for standard RS‑232 signaling ensure compatibility with a wide range of industrial controllers, modems, printers and scanners.

Suitable for

• Embedded systems requiring additional serial and parallel ports
• Industrial controllers and automation equipment
• Connection of legacy peripherals such as modems, serial printers and scanners
• Systems where internal expansion and compact PCB dimensions are required

How to use

Install the DELOCK 95279 into an available Mini PCIe slot inside your system according to the host board manufacturer’s guidance, secure the slot bracket and connect target serial or parallel devices to the bracket outputs. Ensure the host system is powered off during installation to avoid damage. After physical installation, enable the device in the system BIOS/UEFI if required and install any necessary drivers so the operating system recognises the serial and parallel ports. Configure port parameters (baud rate, data bits, parity, stop bits) in the host software or operating system serial port settings to match the connected devices.

Usage recommendations

Use shielded serial cables and proper grounding for reliable RS‑232 communication in electrically noisy environments. Verify driver compatibility with your operating system and test each port after installation. For continuous or high‑throughput applications, configure appropriate flow control and monitor FIFO usage to prevent data loss.
