Sunix MIO6479AL PCIe 2-port Serial RS-232 & 1-port Parallel IEEE1284 Card - Low Profille


(Pictures are For Illustration Purposes Only)



The majority of today’s motherboards are not equipped with any RS-232 or parallel port. With SUNIX MIO5479AL 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 MIO5479AL is compatible with PCI Express x1, x2, x4, x8 and x16 lane and PCI/PCI-x Bus, allowing the board to be installed in any slim size PC-based system with low profile bracket structure. Furthermore, SUNIX MIO5479AL Multi-IO card supports majority of the OS on the market. We provide driver support for Microsoft Windows 32/64-bit platform, WinCE, Linux, making it the best and most economical solution for commercial and industrial applications.
