Product information

Description

The MicroConnect MC-PCIE-MCS2S internal serial interface card is designed to add legacy serial connectivity to desktop computers using a PCIe host interface and reliable ASIX chipset. Equipped with two D-Sub DB-9 serial ports, this controller provides stable data transmission for various peripheral devices in professional and industrial setups. The card comes with both standard and low-profile brackets to accommodate different desktop chassis sizes, ensuring flexible installation options.

Advantages

This internal interface card offers a dependable solution for integrating older serial devices into modern computer systems without compromising performance. The inclusion of an ASIX chipset ensures stable communication and broad operating system compatibility. With support for data transfer rates up to 2.5 Mbps, it handles routine serial communication efficiently. The package includes both standard-profile and low-profile brackets, making the card adaptable for both full-size tower PCs and compact small form factor systems.

Suitable for

  • Connecting legacy serial equipment such as industrial machinery, scientific instruments, and older peripherals to a desktop computer
  • Upgrading modern PCs that lack native D-Sub DB-9 serial ports
  • Professional, office, and industrial environments requiring reliable legacy hardware support
  • Installations in both standard desktop towers and compact low-profile computer cases

When it may not be suitable

This expansion card is not designed for laptops or computers lacking an available PCI Express slot. It may also be unsuitable for users requiring parallel port connectivity, as this specific model focuses exclusively on dual serial interfaces.

Key specifications

  • Host interface: PCIe (PCI Express)
  • Output interface: 2 x D-Sub DB-9 serial ports
  • Chipset: ASIX
  • Maximum data transfer rate: up to 2.5 Mbps
  • Form factor: Internal plug-in card
  • Supported operating systems: Microsoft Windows 2000, XP, Vista, 7, 8, 10, and Windows Server 2003
  • Includes standard-profile and low-profile brackets

How to use

To install the interface card, power off your desktop computer, disconnect it from the power source, and open the chassis. Insert the card into an available PCI Express slot and secure the bracket to the computer case using a screw. Choose either the pre-mounted standard-profile bracket or the included low-profile bracket depending on your PC enclosure size. Once the hardware is securely installed, close the computer case, reconnect the power, and turn on the system. Install the provided drivers to enable full functionality of the serial ports before connecting your external serial devices.

What to consider before purchase

  • Verify that your desktop computer has an available PCI Express slot inside the chassis
  • Check that your operating system version is compatible with the card drivers
  • Confirm that your external peripherals utilize D-Sub DB-9 serial connections
  • Determine whether your computer case requires the standard-profile or low-profile bracket for proper physical installation

Usage recommendations: Ensure the computer is completely powered off and unplugged before performing any internal hardware installation. Handle the interface card by its edges to avoid static discharge and damage to sensitive electronic components.

Ports & interfaces

Serial ports quantity: The number of serial ports in a computer or peripheral. A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. In modern computers and peripherals, serial ports have largely been replaced by USBs and other interfaces.

Performance

Chipset: Set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.
