About this product
The Sunix Mio5079HL is a professional-grade PCI expansion card designed to add 2 high-speed serial ports and 1 parallel port to compatible desktop systems. Built on the reliable SUN1989 chipset, it supports advanced serial speeds up to 1.8Mbps, robust FIFO buffering, and enterprise-level ESD protection, making it ideal for industrial, automation, and legacy device connectivity.
Overview Summary
Sunix Mio5079HL 2-Port Serial and 1-Port Parallel PCI Expansion Card
The Sunix Mio5079HL PCI card delivers stable and flexible I-O expansion for systems that require dependable serial and parallel communication. Featuring a single-slot, low-profile and standard dual bracket design, it integrates easily into a wide range of desktop chassis. Support for both 32-bit and 64-bit PCI environments ensures compatibility with legacy and modern platforms.
Equipped with high-capacity hardware and software FIFO buffers, this card ensures smooth data transmission even in demanding applications. Advanced ESD protection and compliance with IEC1000-4-2 standards provide durability in electrically noisy environments, making it suitable for mission-critical deployments.
The majority of today´s motherboards are not equipped with any RS-232 or parallel port. With SUNIX MIO5079HL Multi I/O board, users can expand two RS-232 and one IEEE1284 parallel ports to their system, allowing them to use serial and parallel devices further. SUNIX MIO5079HL is compatible with both 32/64-bit PCI architecture supporting 3.3 and 5V Bus, allowing the board to be installed in any slim size PC-based system with low profile bracket structure. Furthermore, SUNIX MIO5079HL Multi-IO card supports majority of the OS on the market. We provide driver support for Microsoft Windows 32/64-bit platform, Linux, making it the best and most economical solution for commercial and industrial applications.
Description
The Sunix Mio5079HL is engineered for environments that demand reliable serial and parallel communication.
