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.
DisplayPort is a digital video interface that was designed by the Video Electronics Standards Association (VESA) in 2006 and has been produced since 2008. It competes directly with HDMI®. Unlike... more/see it nowHDMI, however, DisplayPort is an open standard with no royalties.
This digital interface is used primarily between a computer and a monitor or a high-definition television and is built into many computer chipsets produced today. It’s incredibly versatile, with the capability to deliver digital video, audio, bidirectional communications, and accessory power over a single connector.
DisplayPort v1.1 supports a maximum of 10.8 Gbps over a 2-meter cable; v1.2 supports up to 21.6 Gbps. DisplayPort v1.2 also enables you to daisychain up to four monitors with only a single output cable. It also offers the future promise of DisplayPort Hubs that would operate much like a USB hub.
The standard DisplayPort connector is very compact and features latches that don’t add to the connector’s size. Unlike HDMI, a DisplayPort connector is easily lockable with a pinch-down locking hood, so it can't be easily dislodged. However, a quick squeeze of the connector releases the latch.
DisplayPort supports cable lengths of up to 15 meters with maximum resolutions at cable lengths up to 3 meters. Bidirectional signaling enables DisplayPort to both send and receive data from an attached device.
With the proper adapters, DisplayPort cable can carry DVI and HDMI signals, although this doesn’t work the other way around—DVI and HDMI cable can’t carry DisplayPort. Because DisplayPort can provide power to attached devices, DisplayPort to HDMI or DVI adapters don’t need a separate power supply.
The Mini DisplayPort (MiniDP or mDP) is a miniatured version of the DisplayPort interface. It carries both digital and analog computer video and audio signals. Apple® introduced the Mini DisplayPort connector in 2008 and it is now on all new Mac® computers. It is also being used in newer PC notebooks. This small form factor connector fully supports the VESA DisplayPort protocol. It is particularly useful on systems where space is at a premium, such as laptops, or to support multiple connectors on reduced height add-in cards.

Black Box Explains... Digital Optic Cable
Many new, high-quality Mini Disc, pro-audio, DAT (Digital Audio Tape), CD, DVD, and laser disc players, as well as digital amplifiers, DSS satellite receivers, and computer sound cards, are manufactured... more/see it nowwith digital optical output connectors.
These connectors attach to optical cables, which are constructed with a PVC jacket and a plastic core. The cables transfer information accurately over short distances via digital light signals with low loss and no distortion.
Digital optical cable with plastic-core construction is less expensive than fiber optic cable with a glass core, but it still provides the benefits of optical transmission over short distances.
Digital audio makes it possible to use high-quality digital-to-analog converters, which help to maintain the integrity of sound signals from high-end electronic devices.
The two types of connectors associated with digital optical transmission are TOSLINK®, a Toshiba® trademark, and the 3.5-mm Mini Plug connector. collapse

Commercial display advantages of NEC/3M LCD Touchscreen LCDs
When provisioning interactive touchscreens for busy, commercial display applications, it’s important to keep in mind the demands of such uses. For that reason, you have to choose an HID screen... more/see it nowdesigned specifically for harsh use in public spaces, whether in malls, retail stores, airports, or hospitals, and ensure that the screen fits the viewing environment.
Black Box’s NEC®/3M® Touchscreen LCDs are a good choice for such busy venues. Featuring chemically strengthened glass substrate and an advanced design, they are durable enough to withstand heavy daily use, making them ideal for busy interactive wayfinding, retail PoS/PoP, and visitor information service applications—including signage that you expect to operate 24/7 (and don’t want to have to service in the middle of the night).
For one, the touchscreen LCDs boast reliable touch performance, so customers aren’t forced to repeatedly press the glass to advance to the next screen or get their desired content to display. Fitted with 3M® MicroTouch™ Dispersive Signal Technology (DST) overlays, the LCD bezels are unlike most traditional touchscreens that detect touch by interrupting acoustic waves, optical fields, or infrared beams above the surface of the screen; the DST panels detect touch by interpreting bending waves within the glass substrate. High-speed processors and complex algorithms are used to interpret the information and precisely calculate the location of a finger contact, resulting in a fast and accurate touch response.
In addition, the NEC/3M LCD Touchscreen LCDs’ performance isn’t affected by dust and other on-screen contaminants, or even static objects or hands resting on the screens. They’re also designed to operate even if the surface itself is damaged.
Plus, the LCDs themselves are designed for extended use. Available in standard and industrial-strength versions, the professional-grade NEC LCDs boast high brightness and contrast ratios for rendering of crisp images and text in venues with lots of ambient light.
A sealed panel design prevents contaminants like dust, grease, or steam from damaging the LCD panel. Round-The-Clock Scheduler technology enables advanced scheduling of display powering up/down, which can increase the life of the panel while reducing power consumption.
The P Series NEC/3M LCD Touchscreen LCD versions offer additional protection. They boast an industrial-strength design with additional thermal protection and internal temperature sensors with fan-based technology. What’s more, a built-in ambient light sensor automatically adjusts the display’s brightness based on the application’s lighting conditions, helping to reduce energy consumption.
Black Box Explains...Digital Visual Interface (DVI) connectors.
The DVI (Digital Video Interface) technology is the standard digital transfer medium for computers while the HDMI interface is more commonly found on HDTVs, and other high-end displays.
The Digital... more/see it nowVisual Interface (DVI) standard is based on transition-minimized differential signaling (TMDS). There are two DVI formats: Single-Link and Dual-Link. Single-link cables use one TMDS-165 MHz transmitter and dual-link cables use two. The dual-link cables double the power of the transmission. A single-link cable can transmit a resolution ?of 1920 x 1200 vs. 2560 x 1600 for a dual-link cable.
There are several types of connectors: ?DVI-D, DVI-I, DVI-A, DFP, and EVC.
- DVI-D is a digital-only connector for use between a digital video source and monitors. DVI-D eliminates analog conversion and improves the display. It can be used when one or both connections are DVI-D.
- DVI-I (integrated) supports both digital and analog RGB connections. It can transmit either a digital-to-digital signals or an analog-to-analog signal. It is used by some manufacturers on products instead of separate analog and digital connectors. If both connectors are DVI-I, you can use any DVI cable, but a DVI-I is recommended.
- DVI-A (analog) is used to carry an DVI signal from a computer to an analog VGA device, such as a display. If one or both of your connections are DVI-A, use this cable. ?If one connection is DVI and the other is ?VGA HD15, you need a cable or adapter ?with both connectors.
- DFP (Digital Flat Panel) was an early digital-only connector used on some displays.
- EVC (also known as P&D, for ?Plug & Display), another older connector, handles digital and analog connections.
