The majority of today´s motherboards are not equipped with any  serial (RS-232) or parallel (LPT) ports.
With SUNIX MULTIO-3PL multi I/O board, anyone can add two RS-232 and one IEEE1284 parallel port to their system, allowing them to use both serial and parallel devices.
SUNIX MULTIO-3PL 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 via the included low profile bracket.

Furthermore, SUNIX MULTIO-3PL multi-IO card supports all major OS on the market. We provide driver support for Microsoft Windows 32/64-bit platforms and Linux, making it the best and most economical solution for commercial and industrial applications.

  • Adds two RS-232 com ports and one IEEE1284 LPT port to your system.
  • Universal PCI compatible with 64/32-bit PCI-X/PCI Bus and 3.3/5V connector key.
  • High reliability SUNIX SUN1989 16C950 compatible Multi-IO controller on-board.
  • Add two RS-232 serial ports with communication speeds up to 115.2Kbps.
  • On-chip hardware auto flow control to guarantee no data loss.
  • Built-in ±2KV ESD protection for all serial signals.
  • Supports IEEE 1284-1994 parallel port standard
    ECP(Enhance Capacity Port) / EPP(Enhance Parallel Port)
