    OpenRD-Ultimate vs. OpenRD-BS and OpenRD-CS

    OpenRD- Ultimate combines all the functionality of both the OpenRD-BS and OpenRD-CS into one improved more user friendly product, please see the table below for the differences of these 3 versions.




    VGA output




    PCIe slot

    Yes- note1


    Yes- note2, note3

    Audio In/out



    Yes- note4

    TDM slot



    Yes- note4





    USB 2.0 port




    RJ45- Gb




    Note1: Although OpenRD-BS has PCIe x1 interface slot but it is in the middle of the PCB, so user has to open the enclosure to use it.
    Note2: OpenRD-Ultimate has PCIe x 1 slot moved to the front end of PCB, so user can insert their add-on board without opening the enclosure.
    Note3: OpenRD-Ultimate has a switch to select either VGA port or PCIe slot before powering on.
    Note4: OpenRD-Ultimate can select either to use audio interface or TDM slot by two wiring jumpers. These jumpers are located in middle of the PCB, so enclosure must be opened to make the selection.
