DVS400 Extends Any DVI-D Signal up to 220 Feet toTwo Displays and One Local Screen Using CAT6 Cabling While Retaining Perfect Image Quality at Resolutions up to 1920 x 1200SmartAVI, Inc.'s DVS400 allows you to extend a DVI-D signal to up to four displays via one small unit that also loops a signal back to your computer so local monitoring is possible and simple.
A great example would be a retail shop running its digital signage from a computer in its back office; using the DVS400, a media file or group of files could be broadcast to up to two screens situated around the store while also being viewed locally on that computer's monitor.
Quite simply, the outgoing DVI-D signal from your computer is plugged into the DVS400. This box has one input and two outputs, so that your signal can be sent up to 220 feet over inexpensive CAT6 cables to display screens anywhere in your retail shop, lounge, etc. In addition to the two outgoing signal ports, the unit also has a loop-back port that goes back to your computer, so that you may monitor exactly what is being broadcast to the remote screens. This is all done from a single unit with one power supply.
On power-up, the DVS400 reads and stores the EDID of the DVI monitor connected to the local loop-back port. From that point on, even if the local monitor is not attached to the unit, its DDC is retained in the flash memory of the DVS400 unit and it will operate as if the monitor were connected, offering unhindered use and simple flexibility.
