About this product
The Sunix Mio6479HL PCI-Express expansion card adds reliable legacy connectivity to modern systems, combining two high-speed serial ports and one parallel port in a single-slot design with dual bracket support. Built on the Sunix SUN2410 chipset, it delivers stable data transfer, advanced FIFO buffering, and strong ESD protection for industrial and professional environments.
Overview Summary
Sunix Mio6479HL PCI-Express Serial and Parallel Expansion Card
The Sunix Mio6479HL is a PCI-Express x1 interface card designed to extend system connectivity with legacy serial and parallel devices. It features two high-speed serial ports based on the 16C550 controller and one parallel port supporting SPP, BPP, ECP, and EPP modes. The single-slot, dual-bracket design supports both low-profile and standard chassis installations.
With advanced hardware and software FIFO buffering, support for 64-bit operating systems, and high data transfer rates up to 921.6Kbps on serial and 1.8Mbps in turbo mode, this card is suited for demanding commercial and industrial applications. Robust ESD protection ensures long-term reliability in electrically noisy environments.
Performance tier: Professional
Uses: industrial automation, POS systems, legacy peripherals, manufacturing equipment, laboratory devices
Overview
The majority of today's motherboards are not equipped with any RS-232 or Parallel port. With SUNIX MIO6479HL Multi I/O board, users can expand two RS-232 COM and one IEEE1284 LPT ports to their system, allowing them to use serial and parallel devices further. This board is compatible with PCI Express x1, x2, x4, x8 and x16 lane, allowing the board to be installed in virtually any slim size PC system with low profile bracket structure. SUNIX MIO6479HL built-in SUNIX high performance and realizable native PCI Express controller, and as well built with many of SUNIX advanced features and technologies, making it the advanced and high efficient solution for commercial and industrial automation application.
Description
The Sunix Mio6479HL is engineered to provide dependable serial and parallel connectivity for modern PCI-Express systems that still require legacy device support. Its single-slot design integrates two serial ports and one parallel port, while the included low-profile and standard brackets ensure compatibility with a wide range of system enclosures.
Powered by the Sunix SUN2410 chipset, the card supports high-speed data transfer and advanced FIFO buffering, combining 128 byte hardware FIFO with 128k software FIFO to reduce CPU load and improve communication stability. Comprehensive ESD protection safeguards connected equipment, making the Mio6479HL suitable for continuous operation in professional and industrial settings.
