Driving down the highway you may notice a new trend is roadside advertising. Perched atop a metal tower colorful digital signs are capturing the attention of drivers on their way to work, school or returning home. DVI extender units make it possible for remote control and configuration of these high-in-the-sky signs.
Not everyone wants to be over 3,000-feet (1,000 meters) away from their display. However, ask most digital sign technicians and you’ll find they often need to connect to signs over a half a mile away from the control station. Fiber optic DVI extenders make this remote connectivity happen.
Features of CAT5 DVI Extenders
Not all digital displays have to be thousands of feet from the controlling computer. However, it’s not an unusual requirement. Hospitals require displays to be separate and shielded from x-ray and MRI devices. Pharmaceutical and food manufacturers often require a “clean-room” where human and computer equipment is kept to a minimum. Monitors are stationed outside of the room where the technician can manage the process remotely. In this case, using a CAT5 DVI extender instead of a fiber optic DVI extender makes sense.
These situations use inexpensive Cat5/Cat5e/Cat6 cable to transmit the video signals from the computer to the monitor. DVI over CAT5 extenders transmits high quality video signal from any DVI type of device to an electronic display device over UTP or STP Cat5, Cat5e, or Cat6 cable. In fact, the signal can be sent to multiple monitors as the CAT5 DVI extender is available with 2 and 4-port connections.
Financial and investment firms appreciate this type of technology. The DVI extenders allow them to broadcast up-to-the-minute information to multiple remote monitors. These high resolution video splitters support multiple resolutions at varying distances including:
• 200 feet at 1024×768 (XGA)
• 100ft at 1600×1200 (UXGA)
Transmit Digital Signals Over 3280 Feet from the DVI source
Going back to the signage solution where the technician has to setup and configure digital displays from a very long distance. There is a fiber optic DVI extender solution that is also appropriate when operators have to monitor applications that are running in on a computer in a different building. Fiber optic cable is run from one point to another in the different locations. The flat panel display is set up in one building while the application is running in the other building. The video transmissions are sent by the computer over single multimode fiber cable to the monitor that is as much as 3280 feet away from the source.
