Product information

Description

The InLine 76660X is an internal M.2 to dual serial interface card powered by the reliable ASIX AX99100 chipset. Designed to bridge modern motherboards with legacy hardware, this internal expansion card adds two DB9 RS-232 serial ports to your system. Operating efficiently at 3.3V directly through the M.2 slot, it facilitates stable serial communication with a maximum data transfer rate of up to 4 Gbit/s on the host interface and up to 1 Mb/s on the serial ports. It serves as a professional solution for integrating traditional serial devices into contemporary computer systems used in industrial, commercial, and professional environments.

Advantages

This interface card provides a compact and efficient method for adding traditional serial connectivity to modern computer systems that lack native DB9 ports. Built with the ASIX AX99100 controller and 16C950 UART compatibility, it ensures dependable data transmission and flexible serial communication. The direct power supply via the M.2 slot eliminates the need for extra power cables, helping to maintain a clean internal system layout. Furthermore, the inclusion of both low-profile and high-profile slot brackets ensures versatile installation options across various computer chassis types.

Suitable for

  • Connecting industrial machinery and automation equipment with serial ports
  • Integrating legacy POS terminals and barcode scanners into modern setups
  • Communicating with scientific instruments and laboratory hardware
  • Professional system integration and embedded computing applications

This product may not be suitable if your motherboard lacks an available M.2 slot supporting PCIe or if your computer system does not support Windows or Linux operating environments. It is also not intended for consumer peripheral connections that require USB, HDMI, or network interfaces rather than traditional serial RS-232 communication.

Key specifications

  • Internal M.2 to dual serial interface card
  • Host interface: M.2 B+M key with PCIe 2.0 support
  • Output interface: Two male DB9 RS-232 serial ports
  • Controller chipset: ASIX AX99100 with 16C950 UART compatibility
  • Maximum serial transfer rate: Up to 1 Mb/s
  • Power supply: 3.3V via M.2 slot
  • Operating systems supported: Windows and Linux

Installation requires inserting the card into a compatible M.2 slot on the motherboard that supports PCIe communication and securing it properly. Connect the included serial cables from the card ports to your external serial devices, and attach the appropriate slot bracket depending on your computer case size. Power on the system, and configure any necessary settings within your operating system environment to begin utilizing the serial interfaces.

What to consider before purchase

  • Verify that your motherboard has an available M.2 slot with PCIe support
  • Check compatibility with your specific Windows or Linux operating system version
  • Ensure your peripheral devices utilize standard RS-232 serial connections
  • Review the physical dimensions and available case space for bracket installation
Usage recommendations: Ensure the system is powered off and unplugged before installing or removing the M.2 interface card. Handle the circuit board by its edges to prevent electrostatic discharge damage, and securely fasten all cable connections to maintain stable data transmission during continuous industrial operation.
