Sunix MIO6479AL+S 2-port RS-232 & 1-port Parallel PCI Express Multi-I/O Board


(Comes with both Regular & Low-Profile brackets)

The majority of today’s motherboards are not equipped with any RS-232 or Parallel port. With SUNIX MIO6479AL 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 MIO6479AL 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.
