Although multiple computers are connected to the KVM, typically a smaller number of computers can be controlled at any given time. Modern devices have also added the ability to share other peripherals like USB devices and audio.\r\nBefore the mouse became relevant in server switching applications, the term Keyboard Video Switch (KVS) was used to describe keyboard and monitor switching devices. With the increased adoption of Microsoft Windows, the mouse and other I/O ports in peripheral switching became prevalent. Remigius Shatas, the founder of Cybex (a popular peripheral switch manufacturer at that time) expanded the initialism to Keyboard, Video and Mouse (KVM) in 1995. Some years later, Universal Serial Bus (USB) began to become the new industry standard for connecting computer peripherals.\r\nAs a result of the growing need to switch peripherals (such as touchscreens) in addition to the keyboard, mouse and monitor, some companies are now selling &quot;KVMP&quot; switch devices (standing for keyboard, video, mouse and peripheral).\r\nA KVM Switch is a hardware device, used in data centers, that allows the control of multiple computers from a single keyboard, monitor and mouse (KVM). This switch then allows data center personnel to connect to any server in the rack. A common example of home use is to enable the use of the full-size keyboard, mouse and monitor of the home PC with a portable device such as a laptop, tablet PC or PDA, or a computer using a different operating system.\r\nKVM switches offer different methods of connecting the computers. Depending on the product, the switch may present native connectors on the device where standard keyboard, monitor and mouse cables can be attached. Another method to have a single DB25 or similar connector that aggregated connections at the switch with three independent keyboard, monitor and mouse cables to the computers. Subsequently, these were replaced by a special KVM cable which combined the keyboard, video and mouse cables in a single wrapped extension cable. The advantage of the last approach is in the reduction of the number of cables between the KVM switch and connected computers. The disadvantage is the cost of these cables.\r\nThe method of switching from one computer to another depends on the switch. The original peripheral switches (Rose, circa 1988) used a rotary switch while active electronic switches (Cybex, circa 1990) used push buttons on the KVM device. In both cases, the KVM aligns operation between different computers and the users' keyboard, monitor and mouse (user console).\r\nIn 1992-1993, Cybex Corporation engineered keyboard hot-key commands. Today, most KVMs are controlled through non-invasive hot-key commands (e.g. Ctrl+Ctrl, Scroll Lock+Scroll Lock and the Print Screen keys). Hot-key switching is often complemented with an on-screen display system that displays a list of connected computers.\r\nKVM switches differ in the number of computers that can be connected. Traditional switching configurations range from 2 to 64 possible computers attached to a single device. Enterprise-grade devices interconnected via daisy-chained and/or cascaded methods can support a total of 512 computers equally accessed by any given user console.","materialsDescription":" <span style=\"font-weight: bold; \">What is KVM?</span>\r\nKVM is an abbreviation for Keyboard (keyboard), Video (video) and Mouse (mouse), which connect to computer ports. KVM products connected to various ports transmit or switch computer signals.\r\nConsequently, KVM is a designation of a group of technologies, not special brands or companies.\r\n<span style=\"font-weight: bold; \">What is KVM technology?</span>\r\nThe acronym KVM means keyboard, video, and mouse, and refers to computer ports. KVM equipment connects to these and other ports, from where computer signals expand or switch. In this way, KVM stands for technology, not a brand or a company.\r\n<span style=\"font-weight: bold; \">Who needs KVM?</span>\r\nKVM products can be used by anyone using computers.\r\nKVM products are used for:\r\n<ul><li><span style=\"font-weight: bold; \">Noise reduction.</span> Ability to move computers from radio studios.</li><li><span style=\"font-weight: bold; \">Save space.</span> Ability to move computers from an air traffic control tower.</li><li><span style=\"font-weight: bold; \">Protect computers from damage.</span> The ability to move computers from the test room to a secure server room.</li><li><span style=\"font-weight: bold; \">Create more ergonomic consoles.</span> The ability to avoid heat generation by moving computers.</li><li><span style=\"font-weight: bold; \">Reduce the number of peripherals.</span> Ability to control multiple computers using one monitor, keyboard and mouse.</li><li><span style=\"font-weight: bold; \">Simplification of administration.</span> The ability to facilitate maintenance and administration of computers by moving to a central server room.</li><li><span style=\"font-weight: bold; \">Create flexible working concepts.</span> The ability for users to access the computer (s) from various consoles.</li></ul>\r\n<span style=\"font-weight: bold; \">What is a KVM switch?</span>\r\nThe KVM switch connects several computers that can be controlled from a single console (monitor, keyboard, mouse).\r\nSwitching between computers is carried out through the button on the switch or using hotkeys. Depending on size, KVM switches also support OSD technology for switching between computers.\r\nFor example, Guntermann &amp; Druck offers KVM switches for DVI and VGA signals that allow the user to control from two to 64 computers.\r\n<span style=\"font-weight: bold; \">What is a KVM transmitter?</span>\r\nThe KVM transmitter transmits keyboard, video, and mouse signals to control the computer remotely.\r\nEach KVM transmission system consists of a transmitter and a receiver. The transmitter connects to the computer keyboard, video, and mouse interfaces, while the receiver connects to a remote console. Both devices are connected by one or more cables.\r\nVarious suppliers offer KVM transmitters for DVI and VGA signals, which use CAT cable (“twisted pair”) or optical fiber for transmission. Signals such as audio, RS-232, USB 1.1 or USB 2.0 can also be transmitted.\r\n<span style=\"font-weight: bold; \">What do I need to work with KVM switches?</span>\r\nDifferent KVM switches have different requirements. In most cases, all you need is a KVM switch, the required number of cables to connect all your computers, keyboard, monitor and mouse, and, in fact, the computers themselves. This is the basic configuration; more complex systems may require more components.\r\n<span style=\"font-weight: bold; \">What is a matrix KVM switch?</span>\r\nThe matrix KVM switch combines multiple transmitters and switches in one device.\r\nMultiple consoles can access multiple computers - even over long distances. Systems are mainly divided by the type of video signal transmitted. Matrix KVM switches are available for expanding DVI, VGA and other signal signals.\r\nIn addition, matrix switchers are divided into compact devices (specific device characteristics, such as the G&amp;D CompactCenter) and modular systems (such as the G&amp;D DVICenter).\r\n<span style=\"font-weight: bold; \">Why are some KVM switches so much cheaper than others?</span>\r\nAs with all products, some of them have more options. Certain switches offer equipment sharing via USB, On-Screen Display (OSD), audio support, emulation ports, multi-platform capabilities, built-in converters, and shipped with cables and power supplies. You decide whether you need these options or not.\r\n<span style=\"font-weight: bold; \">What is an OSD?</span>\r\nOSD, short for On-Screen Display, is a graphical representation of computers connected to the KVM switch, allowing you to select the computer you want without pressing the buttons on the KVM switch or using hotkeys. If you have a multi-user switch, this function can also show you which computer each user currently has access to.\r\n<span style=\"font-weight: bold; \">What is a video splitter?</span>\r\nThe video splitter allows you to split the VGA/DVI signal and display it on multiple monitors. This product also has several options. You can send these signals via a CAT5 cable or a standard VGA cable. You also have the option of transferring audio for multimedia applications.\r\n<span style=\"font-weight: bold;\">What is a remote reboot?</span>\r\nRemote reboot allows you to reboot servers from anywhere in the world using the Internet. You can do this with a simple web browser.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_KVM_switch.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"benq-px9210":{"id":329,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/BenQ_PX9210.jpg","logo":true,"scheme":false,"title":"BenQ PX9210","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"benq-px9210","companyTitle":"BenQ","companyTypes":["vendor"],"companyId":2736,"companyAlias":"benq","description":"<span style=\"font-weight: bold;\">Brilliant and Reliable Choice for Large Venue Installation</span>\r\nWith five types of optical lenses available and the functions as lens shift, BenQ PX9210 offers great installation and set-up flexibility.

All video projectors use a very bright ultra high pressure mercury lamp, LED or solid state blue, RB, RGB or remote fiber optic RGB lasers to provide the illumination required to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. If a blue laser is used, a phosphor wheel is used to turn blue light into white light, which is also the case with white LEDs. (White LEDs do not use lasers.) A wheel is used in order to prolong the lifespan of the phosphor, as it is degraded by the heat generated by the laser diode. Remote fiber optic RGB laser racks can be placed far away from the projector, and several racks can be housed in a single, central room. Each projector can use up to 2 racks, and several monochrome lasers are mounted on each rack, the light of which is mixed and transmitted to the projector booth using optical fibers. Projectors using RB lasers use a blue laser with a phosphor wheel in conjuntion with a conventional solid state red laser.\r\nVideo projectors are used for many applications such as conference room presentations, classroom training, home cinema and concerts. In schools and other educational settings, they are sometimes connected to an interactive whiteboard. In the late 20th century they became commonplace in home cinema. Although large LCD television screens became quite popular, video projectors are still common among many home theater enthusiasts.\r\nA video projector, also known as a digital projector, may project onto a traditional reflective projection screen, or it may be built into a cabinet with a translucent rear-projection screen to form a single unified display device.\r\nCommon display resolutions include SVGA (800×600 pixels), XGA (1024×768 pixels), SXGA+ (1400x1050 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels), 4K UHD (3840x2160), as well as 16:10 aspect ratio resolutions including WXGA+ (1280x800 pixels) and WUXGA (1920x1200 pixels).\r\nThe cost of a projector is typically driven by its base technology, features, resolution, and light output. A projector with a higher light output (measured in lumens, “lm”) is required for a larger screen or for a room with a larger amount of ambient light. For example, a light output of approximately 1500 to 2500 ANSI lumens is suitable for small screens viewed in rooms with low ambient light; approximately 2500 to 4000 lm is suitable for medium-sized screens with some ambient light; over 4000 lm is needed for very large screens or for use in rooms with no lighting control such as conference rooms. High brightness large-venue models are increasingly common in Boardrooms, Auditoriums and other high profile spaces, and models up to 30,000 lm are used in large staging applications such as concerts, keynote addresses and displays projected on buildings.\r\nA few camcorders have a built-in projector suitable to make a small projection; a few more powerful &quot;pico projectors&quot; are pocket-sized, and many projectors are portable. ","materialsDescription":" <span style=\"font-weight: bold;\">What's the Difference Between DLP LCD, and LED Projectors?</span>\r\nMainstream projectors use one of several technologies to project an image on a wall or screen. Liquid Crystal Display (LCD) projectors, which have been around for years, use three separate glass panels that separate the color spectrum into red, green, and blue to create an image. The newer digital light processing (DLP) processing integrates Texas Instruments’ DLP chip, which is a reflective surface with thousands of tiny, spinning mirrors, takes the reflected light and puts it through a color wheel to create an image. The smallest projectors, called Pico projectors, use solid-state technology, such as Light Emitting Diodes (LEDs), which are desirable in portable projectors for low power consumption.\r\n<span style=\"font-weight: bold;\">How Much Brightness Do I Need?</span>\r\nBrightness (how much light the projector can produce) is measured in ANSI lumens. The brightness of the room where you’ll be projecting will dictate the lumens you will need. That is, brighter rooms need a projector with higher lumens. For dark rooms, 1000 to 1200 lumens is probably adequate, although professional presenters tend to want 1800 lumens or more. In addition, if you are projecting large images, you’ll want a projector with a higher brightness rating. When choosing your projector, consider your application, the size of your group, the size of your room and the amount of light in the room.\r\n<span style=\"font-weight: bold;\">What Resolution Do I Need?</span>\r\nResolution is the term used to describe the number of pixels, used to display an image. Higher resolutions--more pixels are used to create the image--allow you to display more information on your screen and create a crisper, cleaner image. Today, you’ll see a number of possible resolutions: SVGA (800x600 pixels), XGA (1024x768 pixels) and SXGA (1280x1024 pixels). For standard presentations, 800x600 pixels may be sufficient, but for other uses (such as larger images or advanced presentations) you’ll want a higher resolution, such as 1024x768. The highest resolutions may be needed for presenting detailed AutoCAD drawings or videos.\r\n<span style=\"font-weight: bold;\">What Contrast Ratio Do I Need?</span>\r\nContrast ratio measures how well a projector can reproduce black and white. Although the contrast ratio is not terribly important to those using projectors for still presentations, this measure is more important if you will be projecting video. Currently, there is no industry-standard method for measuring contrast ratio, so this stat may vary between manufacturers. Basically, a higher contrast ratio indicates a greater ability for the projector to show subtle color details and tolerate extraneous room light.\r\n<span style=\"font-weight: bold;\">What Input/Output Options Do I Want?</span>\r\nToday’s projectors offer an array of input and output connectors. A projector with both HDMI and VGA ports lets you connect to many different video sources, including set-top boxes; DVD, HD DVD, and Blu-ray Disc players; camcorders; PCs; video game consoles; and AV receivers. HDMI (High-Definition Multimedia Interface) supports any uncompressed TV or PC video format on a single cable, including standard, enhanced, and high-definition video; up to eight channels of compressed or uncompressed digital audio; a Consumer Electronics Control (CEC) connection; and an Ethernet data connection.\r\n<span style=\"font-weight: bold;\">How Much Should I Worry About Projector Weight?</span>\r\nCommon sense should reign when decided what size projector to buy. Consider whether you will be traveling with your projector and choose accordingly. A hard-sized case with wheels will also ease transport.\r\n<span style=\"font-weight: bold;\">What Is a Normal Warranty?</span>\r\nDepending on the projector brand, warranties do vary. Generally, the projector is covered for a year, with the lamp having a shorter coverage (30 days to six months).\r\n<span style=\"font-weight: bold;\">How Long Will My Lamp Last?</span>\r\nBoth DLP and LCD projectors integrate lamps (light bulbs optimized for use in a projector). Lamp life is measured in hours (example, 2000 or 4000), which for most users will translate to years of use. Over time, the brightness of the lamp may deteriorate. LED projectors, meanwhile, do not use a lamp. The result is that these projectors generate less heat and demand virtually no maintenance. Meanwhile, since LEDs incorporate no lead or mercury, these projectors provide a compelling solution for those seeking a green projector.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Projector.jpg"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"canon-xeed-wux500st":{"id":830,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Canon_XEED_WUX500ST.png","logo":true,"scheme":false,"title":"Canon XEED WUX500ST","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"canon-xeed-wux500st","companyTitle":"Canon","companyTypes":["vendor"],"companyId":2742,"companyAlias":"canon","description":"Installation flexibility\r\nVertical and horizontal lens shift capability (75% and 10% respectively) allows for superb versatility when selecting where to locate the projector.\r\nCrisp, precise images\r\nWUXGA-resolution LCOS panels deliver accurate, detailed images, ideal for corporate presentations as well as installation usage.\r\nBold, punchy colours\r\nCanon’s AISYS technology produces 5,000-lumens colour brightness and a high 2,000:1 contrast ratio, delivering engaging images.\r\nSuperb power efficiency\r\nWith 395-watt power consumption, the XEED WUX500ST offers best-in-class efficiency.

A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Older monitors used a cathode ray tube (CRT). Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, Thunderbolt, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.\r\nOriginally, computer monitors were used for data processing while television sets were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4:3 to 16:10, to 16:9.\r\nModern computer monitors are easily interchangeable with conventional television sets. However, as computer monitors do not necessarily include integrated speakers, it may not be possible to use a computer monitor without external components.","materialsDescription":" <span style=\"font-weight: bold; \">What is an LCD monitor (TFT)?</span>\r\nLiquid crystal monitor (also Liquid crystal display, LCD monitor, flat indicator) - a flat monitor based on liquid crystals.\r\nLCD TFT is one of the names of the liquid crystal display, which uses an active matrix controlled by thin-film transistors. The TFT amplifier for each subpixel is used to increase the speed, contrast and clarity of the display image.\r\n<span style=\"font-weight: bold; \">How does an LCD monitor work?</span>\r\nEach pixel of the LCD display consists of a layer of molecules between two transparent electrodes, and two polarizing filters, the polarization planes of which (as a rule) are perpendicular. In the absence of liquid crystals, the light transmitted by the first filter is almost completely blocked by the second.\r\nThe surface of the electrodes in contact with liquid crystals is specially processed for the initial orientation of the molecules in one direction. In the TN matrix, these directions are mutually perpendicular, therefore, the molecules line up in a helical structure in the absence of voltage. This structure refracts the light in such a way that, before the second filter, the plane of its polarization rotates, and light passes through it already without loss. Except for the absorption by the first filter of half of the unpolarized light, the cell can be considered transparent. If voltage is applied to the electrodes, the molecules tend to line up in the direction of the field, which distorts the helical structure. In this case, the elastic forces counteract this, and when the voltage is turned off, the molecules return to their original position. With a sufficient field value, almost all molecules become parallel, which leads to the opacity of the structure. By varying the voltage, you can control the degree of transparency. If a constant voltage is applied for a long time, the liquid crystal structure may degrade due to ion migration. To solve this problem, an alternating current is applied, or a change in the field polarity at each addressing of the cell (the opacity of the structure does not depend on the field polarity). In the entire matrix, each of the cells can be controlled individually, but with an increase in their number this becomes difficult to accomplish, as the number of required electrodes increases. Therefore, row and column addressing is used almost everywhere. The light passing through the cells can be natural - reflected from the substrate (in LCD displays without backlight). But more often an artificial light source is used, in addition to independence from external lighting, this also stabilizes the properties of the resulting image. Thus, a full-fledged LCD monitor consists of electronics that process the input video signal, LCD matrix, backlight module, power supply and housing.

These modules traditionally come in the form of a plug-in card or an external device that attaches directly to a computer or network server.\r\nSome providers in this discipline consider that the key difference between hardware security and software security is that hardware security is implemented using &quot;non-Turing-machine&quot; logic (raw combinatorial logic or simple state machines). One approach, referred to as &quot;hardsec&quot;, uses FPGAs to implement non-Turing-machine security controls as a way of combining the security of hardware with the flexibility of software.\r\nHardware backdoors are backdoors in hardware. Conceptionally related, a hardware Trojan (HT) is a malicious modification of an electronic system, particularly in the context of an integrated circuit.\r\nA physical unclonable function (PUF) is a physical entity that is embodied in a physical structure and is easy to evaluate but hard to predict. Further, an individual PUF device must be easy to make but practically impossible to duplicate, even given the exact manufacturing process that produced it. In this respect, it is the hardware analog of a one-way function. The name &quot;physically unclonable function&quot; might be a little misleading as some PUFs are clonable, and most PUFs are noisy and therefore do not achieve the requirements for a function.

Many peripherals are external devices that give you a way to input information. For example, you might use a mouse or trackpad to navigate the screen, a keyboard to type text or a microphone to record audio. Other peripherals are output devices that let you see, print or listen to something, such as monitors, printers, and speakers. While debatable since they are key components for a functional computer, internal devices like hard drives and memory may be considered peripherals.\r\nKeyboards, mice, touchpads and other Human Interface Devices are very common peripherals of computer systems. A HID is a peripheral that lets the computer use input data or interact with the computer. HIDs are always considered peripheral devices because it is possible for a computer to operate and do countless jobs without the need for human interaction. You can disconnect an HID from a computer and replace it with a new one without affecting the core functionality of the system.\r\nData storage devices are hardware devices capable of holding information and include system RAM, internal hard drives, external hard drives, solid-state drives, flash drives, memory cards, and cassettes. Any type of storage device that connects outside of the computer, or isn't necessary for the computer to run, is considered a peripheral. For example, you can connect and disconnect external hard drives, flash drives and memory cards without disabling the computer. However, system RAM and internal hard drives straddle the peripheral line. While the motherboard and CPU have small amounts of built-in memory, alone, they are not enough to utilize most of the computer's capabilities.\r\nUnless a computer operates in a self-contained situation, without any need for human interaction, it's necessary for the computer to convey information to the user. The computer uses peripheral devices like monitors, speakers and screen readers to translate the system's binary data stream into something people can understand and interact with. Computer peripheral devices encompass all devices that the system uses to output data, including printers. The data output devices aren't essential for the computer to operate, they're just needed to make the system useful.\r\nAny type of peripheral card, like a graphics card, sound card, network card or controller card, is considered a peripheral. Most modern non-storage based internal storage devices use the Peripheral Component Internet and PCI Express connection standards. The connection standard name itself implies that what ever hardware uses it is a peripheral device. While peripheral devices are necessary for things like displaying video output and communicating with other computers on a network, the computer can still operate without them.","materialsDescription":" <span style=\"font-weight: bold;\">What is a peripheral device?</span>\r\nA peripheral is a hardware input device or output device that gives a computer additional functionality.

Companies use SCADA systems to control equipment across their sites and to collect and record data about their operations. SCADA is not a specific technology, but a type of application. Any application that gets operating data about a system in order to control and optimise that system is a SCADA application. That application may be a petrochemical distillation process, a water filtration system, a pipeline compressor, or just about anything else.\r\nSCADA solutions typically come in a combination of software and hardware elements, such as&nbsp;programmable logic controllers (PLCs) and remote terminal units (RTUs). Data acquisition in SCADA starts with PLCs and RTUs, which communicate with plant floor equipment such as factory machinery and sensors. Data gathered from the equipment is then sent to the next level, such as a control room, where operators can supervise the PLC and RTU controls using human-machine interfaces (HMIs). HMIs are an important element of SCADA systems. They are the screens that&nbsp;operators&nbsp;use to communicate with the SCADA system.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">The major components of a SCADA technology include:</span></p>\r\n<ul><li><span style=\"font-weight: bold;\">Master Terminal Unit (MTU).</span> It comprises a computer, PLC and a network server that helps MTU to communicate with the RTUs.

RTUs have the storage capacity facility. So, it stores the data and transmits the data when MTU sends the corresponding command.</li><li><span style=\"font-weight: bold;\">Communication Network (defined by its network topology).</span> In general, network means connection. When you tell a SCADA communication network, it is defined as a link between RTU in the field to MTU in the central location.

Effective SCADA systems can result in significant savings of time and money. Numerous case studies have been published highlighting the benefits and savings of using a modern SCADA software.\r\n<h1 class=\"align-center\">Benefits of using SCADA software</h1>\r\nUsing modern SCADA software provides numerous benefits to businesses, and helps companies make the most of those benefits. Some of these advantages include:\r\n<span style=\"font-weight: bold; \">Easier engineering:</span> An advanced supervisory control application such provides easy-to-locate tools, wizards, graphic templates and other pre-configured elements, so engineers can create automation projects and set parameters quickly, even if they don't have programming experience. In addition, you can also easily maintain and expand existing applications as needed. The ability to automate the engineering process allows users, particularly system integrators and original equipment manufacturers (OEM), to set up complex projects much more efficiently and accurately.\r\n<span style=\"font-weight: bold; \">Improved data management:</span> A high-quality SCADA system makes it easier to collect, manage, access and analyze your operational data. It can enable automatic data recording and provide a central location for data storage. Additionally, it can transfer data to other systems such as MES and ERP as needed. \r\n<span style=\"font-weight: bold; \">Greater visibility:</span> One of the main advantages of using SCADA software is the improvement in visibility into your operations. It provides you with real-time information about your operations and enables you to conveniently view that information via an HMI. SCADA monitoring can also help in generating reports and analyzing data.\r\n<span style=\"font-weight: bold; \">Enhanced efficiency:</span> A SCADA system allows you to streamline processes through automated actions and user-friendly tools. The data that SCADA provides allows you to uncover opportunities for improving the efficiency of the operations, which can be used to make long-term changes to processes or even respond to real-time changes in conditions.\r\n<span style=\"font-weight: bold; \">Increased usability:</span> SCADA systems enable workers to control equipment more quickly, easily and safely through an HMI. Rather than having to control each piece of machinery manually, workers can manage them remotely and often control many pieces of equipment from a single location. Managers, even those who are not currently on the floor, also gain this capability.\r\n<span style=\"font-weight: bold; \">Reduced downtime:</span> A SCADA system can detect faults at an early stage and push instant alerts to the responsible personnel. Powered by predictive analytics, a SCADA system can also inform you of a potential issue of the machinery before it fails and causes larger problems. These features can help improve the overall equipment effectiveness (OEE) and reduce the amount of time and cost on troubleshooting and maintenance.\r\n<span style=\"font-weight: bold;\">Easy integration:</span> Connectivity to existing machine environments is key to removing data silos and maximizing productivity. \r\n<span style=\"font-weight: bold;\">Unified platform:</span>All of your data is also available in one platform, which helps you to get a clear overview of your operations and take full advantage of your data.

A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Older monitors used a cathode ray tube (CRT). Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, Thunderbolt, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.\r\nOriginally, computer monitors were used for data processing while television sets were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4:3 to 16:10, to 16:9.\r\nModern computer monitors are easily interchangeable with conventional television sets. However, as computer monitors do not necessarily include integrated speakers, it may not be possible to use a computer monitor without external components.","materialsDescription":" <span style=\"font-weight: bold; \">What is an LCD monitor (TFT)?</span>\r\nLiquid crystal monitor (also Liquid crystal display, LCD monitor, flat indicator) - a flat monitor based on liquid crystals.\r\nLCD TFT is one of the names of the liquid crystal display, which uses an active matrix controlled by thin-film transistors. The TFT amplifier for each subpixel is used to increase the speed, contrast and clarity of the display image.\r\n<span style=\"font-weight: bold; \">How does an LCD monitor work?</span>\r\nEach pixel of the LCD display consists of a layer of molecules between two transparent electrodes, and two polarizing filters, the polarization planes of which (as a rule) are perpendicular. In the absence of liquid crystals, the light transmitted by the first filter is almost completely blocked by the second.\r\nThe surface of the electrodes in contact with liquid crystals is specially processed for the initial orientation of the molecules in one direction. In the TN matrix, these directions are mutually perpendicular, therefore, the molecules line up in a helical structure in the absence of voltage. This structure refracts the light in such a way that, before the second filter, the plane of its polarization rotates, and light passes through it already without loss. Except for the absorption by the first filter of half of the unpolarized light, the cell can be considered transparent. If voltage is applied to the electrodes, the molecules tend to line up in the direction of the field, which distorts the helical structure. In this case, the elastic forces counteract this, and when the voltage is turned off, the molecules return to their original position. With a sufficient field value, almost all molecules become parallel, which leads to the opacity of the structure. By varying the voltage, you can control the degree of transparency. If a constant voltage is applied for a long time, the liquid crystal structure may degrade due to ion migration. To solve this problem, an alternating current is applied, or a change in the field polarity at each addressing of the cell (the opacity of the structure does not depend on the field polarity). In the entire matrix, each of the cells can be controlled individually, but with an increase in their number this becomes difficult to accomplish, as the number of required electrodes increases. Therefore, row and column addressing is used almost everywhere. The light passing through the cells can be natural - reflected from the substrate (in LCD displays without backlight). But more often an artificial light source is used, in addition to independence from external lighting, this also stabilizes the properties of the resulting image. Thus, a full-fledged LCD monitor consists of electronics that process the input video signal, LCD matrix, backlight module, power supply and housing. It is the combination of these components that determines the properties of the monitor as a whole, although some characteristics are more important than others.\r\n<span style=\"font-weight: bold;\">What are the most important features of LCD monitors?</span>\r\n<ul><li><span style=\"font-style: italic;\">Resolution:</span> The horizontal and vertical sizes, expressed in pixels.

These displays use gas-discharge plasma cells as a brightness controller, and an LCD matrix is ​​used for color filtering. PALC technology allows you to address each pixel of the display individually, which means unsurpassed controllability and image quality.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Monitor.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}},"aliases":{"1":["avocent-matrix-digital-high-performance-kvm-system","benq-px9210","canon-xeed-wux500st","lg-video-wall-displays","secure-8-port-dual-head-kvm-switches","viewboard"]},"links":{"first":"http://apis.roi4cio.com/api/products?page=1","last":"http://apis.roi4cio.com/api/products?page=1","prev":null,"next":null},"meta":{"current_page":1,"from":1,"last_page":1,"path":"http://apis.roi4cio.com/api/products","per_page":20,"to":6,"total":6},"loading":false,"error":null,"useProductLoading":false,"sellProductLoading":false,"templatesById":{},"comparisonByTemplateId":{}},"filters":{"filterCriterias":{"loading":false,"error":null,"data":{"price":{"min":0,"max":6000},"users":{"loading":false,"error":null,"ids":[],"values":{}},"suppliers":{"loading":false,"error":null,"ids":[],"values":{}},"vendors":{"loading":false,"error":null,"ids":[],"values":{}},"roles":{"id":200,"title":"Roles","values":{"1":{"id":1,"title":"User","translationKey":"user"},"2":{"id":2,"title":"Supplier","translationKey":"supplier"},"3":{"id":3,"title":"Vendor","translationKey":"vendor"}}},"categories":{"flat":[],"tree":[]},"countries":{"loading":false,"error":null,"ids":[],"values":{}}}},"showAIFilter":false},"companies":{"companiesByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
