Application Notes

  •   How to Cascade Units & Display More Than 4 Sources on 1 Screen
    How to Cascade Units & Display More Than 4 Sources on 1 Screen
    Cascade any number of SPLITMUX units, with one as the master unit and others as slaves. A slave can also have slaves, and the SPLITMUX supports any number of slave levels. After connecting the slave to the master unit, configure the cascade using the Cascade Settings page on the Web Interface.

    In this example, five units are configured in a master and slave cascade with each unit configured for Quad mode. Since the SPLITMUX can only accept input resolutions up to 2K, the output of all connected slave units must be set to 2K or lower. On the master unit, only Quad and Full Screen mode will support 4Kx2K output resolutions, while Picture in Picture and Custom mode will support up to 2K output resolutions.

    Notes:
    1. If there is no input for a channel, its window will be white.
    2. If no layering is required, the order of inputs is inconsequential.
    3. If layering is pertinent to the display desired, it is recommended to connect the back layers to a slave unit and the front layers to a master unit.
