Our line of Low Profile PCI RS-232 boards provide truly universal connectivity, enabling a single product to be used to implement systems with dramatically different resource requirements. These boards use a universal PCI connector compatible with both the 3.3V signaling support required for plug-in boards by the PCI 2.3 specification and the 5V signaling still used by many systems. They are designed on the smallest MD1 Low Profile footprint, but come with both a full size ORB for standard systems, and a smaller ORB for use in Low Profile backplanes to fit even 2U racks without riser cards. In addition, our wide range of OS options facilitate both system upgrades and multiplatform installations.
