## Long description

DELOCK 95278 is an internal Mini PCI Express interface card that provides four RS-232 serial outputs on a compact PCB measuring 30×51×10 mm. Designed for installation inside desktop systems, industrial PCs and embedded platforms, the board adds four additional COM ports via the host Mini PCIe slot. The module includes male straight RS-232 connectors and a 256‑byte FIFO buffer to improve data flow and reduce host CPU load. The card supports modern Windows platforms including Windows 10, Windows 11 and Windows Server 2022.
Advantages
The internal Mini PCIe form factor saves external space and keeps serial cabling tidy inside the chassis. Four independent RS-232 outputs let you connect multiple legacy or industrial serial devices simultaneously. The built‑in 256 B FIFO buffer helps stabilise data transmissions and minimises packet loss during bursts of serial traffic. Native driver support for current Windows versions simplifies deployment in systems that require reliable COM port functionality.
Suitable for
Connecting serial printers and label printers to PCs
Point-of-sale (POS) systems and cash register peripherals
Industrial equipment and PLC communication requiring RS-232
Legacy modems, barcode scanners and measurement instruments
Embedded systems and small form-factor PCs that need extra COM ports

How to use
Install the DELOCK 95278 into an available Mini PCIe slot on the motherboard following anti‑static procedures. Secure the board and route internal serial cables to the required device locations. After hardware installation, boot the system and install the appropriate drivers for your Windows version if not already present; the card will then expose four COM ports in the operating system. Configure baud rate, parity, stop bits and flow control in the target application or device manager according to the connected device specifications.
Usage recommendations
Use shielded serial cables and keep cable runs as short as practical to reduce noise and maintain reliable RS-232 signalling. Verify driver compatibility with your specific Windows build before deploying in production. For industrial environments, mount the board within an enclosure that provides adequate cooling and protection from dust and vibration.
