Black Box Explains...Upgrading from VGA to DVI video.

Many new PCs no longer have traditional Cathode Ray Tube (CRT) computer monitors with a VGA interface. The latest high-end computers have Digital Flat Panels (DFPs) with a Digital Visual... more/see it nowInterface (DVI). Although most computers still have traditional monitors, the newer DFPs are coming on strong because flat-panel displays are not only slimmer and more attractive on the desktop, but they’re also capable of providing a much sharper, clearer image than a traditional CRT monitor.

The VGA interface was developed to support traditional CRT monitors. The DVI interface, on the other hand, is designed specifically for digital displays and supports the high resolution, the sharper image detail, and the brighter and truer colors achieved with DFPs.

Most flat-panel displays can be connected to a VGA interface, even though using this interface results in inferior video quality. VGA simply can’t support the image quality offered by a high-end digital monitor. Sadly, because a VGA connection is possible, many computer users connect their DFPs to VGA and never experience the stunning clarity their flat-panel monitors can provide.

It’s important to remember that for your new DFP display to work at its best, it must be connected to a DVI video interface. You should upgrade the video card in your PC when you buy your new video monitor. Your KVM switches should also support DVI if you plan to use them with DFPs. collapse

  • Video...iCompel™ How-To (Part 4): Creating layouts for Digital Signage

    This video tutorial goes into great detail to show how to create layouts for the iCOMPEL digital signage player. It demonstrates the interface and how to choose a layout canvas... more/see it nowsize for the attached screen resolution; how to upload media into folders; and how to create and design a screen layout. Also explained: adding zones to the layout canvas, defining the type of content that zones will play, resizing zones, adding content to layouts, and more. collapse


Black Box Explains...Gold plating.

Get premium-quality connectors from Black Box. The 24-karat gold plating ensures better signal transmission and no corrosion. The shielding and heavy gold conductors provide improved performance.


Black Box Explains... Speaker wire gauge.

Wire gauge (often shown as AWG, for American Wire Gauge) is a measure of the thickness of the wire. The more a wire is drawn or sized, the smaller its... more/see it nowdiameter will be. The lower the wire gauge, the thicker the wire.

For example, a 24 AWG wire is thinner than a 14 AWG wire. A lower AWG means longer transmission distance and better integrity. As a rule of thumb, power loss decreases as the wire size increases.

When it comes to choosing speaker cable, consider a few factors: distance, the type of system and amplifier you have, the frequencies of the signals being handled, and any specifications that the speaker manufacturer recommends.

For most home applications where you simply need to run cable from your stereo to speakers in the same room—or even behind the walls to other rooms—16 AWG cable is usually fine.

If you’re considering runs of more than 40 feet (12.1 m), consider using 14 AWG or even 12 AWG cable. They both offer better transmission and less resistance over longer distances. You should probably choose 12 AWG cable for high-end audio systems with higher power output or for low-frequency subwoofers. As a rule of thumb, power loss decreases as the wire size increases.

To terminate your cable, choose gold connectors. Because gold resists oxidation over time, gold connectors wear better and offer better peformance than other connectors do. collapse

  • Video...iCOMPEL™ How-To (Part 8): Learn more about advanced features.

    This video provides an overview of the advanced features of the iCOMPEL™ digital signage platform. It shows how to access the folder play feature so you can place a folder... more/see it nowfull of content files directly into a iCOMPEL playlst, as well as the ad-hoc feature, which enables a user at a specific screen location to add or change text displayed within a layout zone. Also, the video covers: advance to/rendezvous points, conditional play, and how to add captioning. collapse


Black Box Explains...Controlling GPIO interfaces with iCOMPEL.

With the iCOMPEL™, interactivity goes beyond touchscreen support. It also supports general-purpose input/output (GPIO) capabilities. Through an external device with a GPIO interface, the playing of on-screen information can be... more/see it nowtriggered (or halted) by signals originating from device inputs via contact closures. These can be external infrared motion detectors, light sensors, switches, push buttons, building control systems—even external SCADA collection systems.

The possibilities are endless. You can set up a screen to provide emergency notification during crises—based on a signal sent when a secure door is opened or when an environmental condition occurs. Or simply use a screen to welcome visitors walking through your main door. You can even have a screen change from a static display to an interactive touchscreen when someone approaches.

Just connect the external device to the iCOMPEL using our ICOMP-GPIO Adapter, which adapts the USB port on the iCOMPEL to a DB9 (RS-232) port. (NOTE: Older iCOMPEL units include a DB9 port, so the adapter isn’t needed.) This adapted port can be used for sending user-defined RS-232 strings and receiving RS-232 strings. The port also offers four input lines for binary events, such as motion detection, contact closure, or other device signaling. In some cases, you can even use the RS-232 connection to power simple detection devices.

Each RS-232 input item can be included in a playlist and used to generate an Advance To or Change Layout on a user-defined transition of the line. The Advance To or Change Layout commands can be configured to change the media being played by the iCOMPEL.

The iCOMPEL has the ability to control the output state of the RS-232 DTR and RTS lines. The lines are controlled by RS-232 output items, which can appear as items in the iCOMPEL playlist menu. The RS-232 output items can assign the state of one or both RS-232 output lines and optionally a string of characters to be output.

For further details on how to activate touchscreen and contact closure capabilities on an iCOMPEL unit, contact our FREE Tech Support. Our experts can also recommend accessories for motion detection and other GPIO-controlled functions.
