Application Notes

  • Display video from four computers simultaneously on multiple screens and switch the audio to different speakers
    Loading image...

    Interconnect the SPLITMUX® Quad Screen Splitter with the VEEMUX® Audio/Video Matrix Switch to simultaneously display video signals from four different computers on multiple screens while switching the audio from each computer to different speakers.

    Monitors and speakers can be extended up to 600 feet (183 meters) away by interconnecting the XTENDEX® VGA + Audio Extender and the VEEMUX® switch.

  • Save Space on Mobile Video Surveillance Missions
    Loading image...

    Eliminate the need to carry multiple monitors/LCDs on a surveillance mission in a vehicle. The SPLITMUX Quad Screen Splitter splits a screen into various display areas, showing the input from four different video sources at once.

    Ideal for counter-terrorism, border patrol, law enforcement, military, or medical and industrial applications.

  • Cascade mulitple Quad Screen Splitters to connect up to 16 video sources to one display.
    Loading image...

    Display video from up to 16 video sources simultaneously on one touch screen monitor by cascading SPLITMUX® Quad Screen Splitters. With all of the Quad Screen Splitters in Quad Mode, a master splitter connects to four slave splitters, with each slave splitter connecting to four DVI video sources.

    If less than four Quad Screen Splitters are cascaded, the unused channels on the master splitter will need to be disabled. Example: If two Quad Screen Splitters are cascaded from the master splitter, and connected to inputs one and two, then inputs three and four would need to be disabled.

    Note: Higher refresh rates output smoother video, but the best frame rate that can be displayed for each quadrant on the display is about 15 frames/sec.

  • Extend Touchscreen Monitor, Keyboard, & Mouse Up to 200ft Away From Quad Screen Splitter
    Loading image...
    The ST-C5USBVT Transparent USB Extender with VGA Video can be connected to the SPLITMUX-DVI-4(RT) to locate a remote touchscreen monitor, keyboard, and mouse up to 200 feet away from the quad screen splitter. Use USB male Type A to male Type B and DVI-I male to VGA male cables to connect the local extender unit to the SPLITMUX.

    A local monitor can also be connected to the ST-C5USBVT transmitter. To control the local monitor, connect a USB hub to the second SPLITMUX-DVI-4(RT) console USB port to set up a keyboard and mouse.
  • "The SPLITMUX-DVI-4 is a nice product. We used it for our audio multitrack workstations on Stand Up To Cancer, a television show, and it worked very well. We used it again last weekend on a taping of a Kathy Griffin special where it also worked well. I showed it to a number of folks on those shows who were quite impressed.

    I've spent time trying to get it to fail (because in live television if it can fail, it will) - powering things in the wrong order, connecting and reconnecting things, changing resolutions, and it always seems to deal with it. Its ability to auto-scale anything seems to work very well. The hotkeys and the "hotmouse" functionality, both of which I thought were gimmicks, ended up being the primary user interface. Note - the ability to set our own hotkey combination is important - we ended up using ctrl-alt-windows because that's available. The default of ctrl-alt is used in too many audio workstations.

    One nice small feature - our operators all want to use Kensington trackballs, and Kensingtons will not switch smoothly with any KVM, as Kensington will tell you. I've tried almost all of them. The SPLITMUX unit keeps the connection so when we switch to a computer, the Kensington is operational. Whatever you're doing with the Kensington HID, it works.

    Thanks for your policy of demoing this unit - that sold us on its abilities. It's been a big hit here."
