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.

Black Box Explains...Digital Visual Interface (DVI) and other digital display interfaces.

There are three main types of digital video interfaces: P&D, DFP, and DVI. P&D (Plug & Display, also known as EVC), the earliest of these technologies, supports both digital and... more/see it nowanalog RGB connections and is now used primarily on projectors. DFP (Digital Flat-Panel Port) was the first digital-only connector on displays and graphics cards; it’s being phased out.

There are different types of DVI connectors: DVI-D, DVI-I, DVI-A, DFP, and EVC.

DVI-D is a digital-only connector. DVI-I supports both digital and analog RGB connections. Some manufacturers are offering the DVI-I connector type on their products instead of separate analog and digital connectors. DVI-A is used to carry an analog DVI signal to a VGA device, such as a display. DFP, like DVI-D, was an early digital-only connector used on some displays; it’s being phased out. EVC (also known as P&D) is similar to DVI-I only it’s slightly larger in size. It also handles digital and analog connections, and it’s used primarily on projectors.

All these standards are based on transition-minimized differential signaling (TMDS). In a typical single-line digital signal, voltage is raised to a high level and decreased to a low level to create transitions that convey data. TMDS uses a pair of signal wires to minimize the number of transitions needed to transfer data. When one wire goes to a high-voltage state, the other goes to a low-voltage state. This balance increases the data-transfer rate and improves accuracy. collapse
