Display

In this group, we can choose the parameters: size, resolution, touch, light, kind of.

Size:

Screen size is the size of the display of our device. Is given in inches (1 inch is approx. 2.54 cm). The higher the diagonal of this, of course, a larger display device.  Available in tablets and data collectors are different screen size.

Resolution:

This parameter specifies the number of pixels in the image displayed on the screen in the current display mode, the image is made of pixels. Resolution is expressed as the number of pixels in the horizontal and vertical. Resolution level consists of a vertical line, while the horizontal lines vertically.

Standard on-screen resolution

Touch type:

 Screen Resistance / Resistance

 Touch-sensitive surface is made of two plastic plates. On the surface of the plate is a thin and scratch-resistant plastic. Is also coated with a thin layer of conductive material (tin oxide and indium oxide) placed on the bottom of "fast". At the upper long (i.e., below the conductive material), a second plastic plate. Both plates have no contact with each other until the user of the device does not press the screen with your finger or stylus. Contact occurs between spaced slightly screens. As a result of contact created a short circuit that by measuring the vertical and horizontal resistance is converted to data indicating the CPU contact area.

Screen resistive / resistive resistive screen provides good visibility, but that falls quite heavily in the sun. This type of screen, as opposed to capacitive screen, allows the use of ink (useful herein stylus). About multitouchu we can only dream of.

Capacitive screen

The capacitive touch generally consists of a fast-coated glass insulator (similar to that used in screens resistance). Touching the surface of the plate with a finger or other thing, conductive causes disruption in the flow of current. Next, place your finger from the screen interface is measured from the four corners of the screen.

Capacitive screen also provides decent visibility in the sun. We can only handle it with your finger or conductive materials. Is inconvenient in the winter, because we have to take off the gloves to be able to do anything on the phone (you can use special gloves). Some phones at subzero temperatures can go crazy and the screens do not read properly our gestures. This type of touch panel provides us with an unusual facility, which is to support multitouch technology.

Brightness:

The light emitted perpendicular to the surface of the glowing (and reflective). In this way, we describe the amount of light that is emitted from a particular area and the incident at a specific angle. This value is given in candelas per square meter (cd / m2).

Type:

IPS

Matrices of this type are characterized by a very wide viewing angles horizontally and vertically, have uniform illumination and better color fidelity mapped. In conjunction with control systems that operate on a 12-bit color patterns and enable 16-bit color processing, and further supported by the DUE function, are the ideal solution for even the most demanding users, using them for professional use.

5-WIRE RESISTIVE SCREENS

IR Technology

IR technology is also not resistant to accidental touch or covering the frame emitting infrared radiation. If the monitor is outdoor, for example, it is exposed to an accidental contact with a falling leaf, which can be interpreted by IR as a touch. It is also an advantage of the technology - it has a high sensitivity to touch. Also, it recognizes the touch in a glove. Solutions with infrared touch-sensing technology can be used in very large screens. In addition, this technology is cheap.

Vandal-proof SAW Touch Screen

This type of touchscreen uses tempered glass, which provides excellent impact performance and strength several times that of ordinary glass. Even if a touchscreen is broken, the fragments are safe with no sharp edges. Special anti-vandalism design for applications in industry, nobody-on-duty and public, with excellent performance for safety and anti-vandalism.

SAW Acoustic Technology

The principle of SAW acoustic technology is similar to IR technology. Acoustic wave emitters that cover the monitor are necessary. When the screen is touched, the sound wave is partly absorbed, causing the registration of touch. You do not need a special coating, so there is no concern about the distortion of the image presented on the monitor. The technology is cheap and proven, which guarantees its low failure rate. In addition, touch screens, acting on the basis of SAW acoustic technology can be used outdoor and in other public places. SAW acoustic technology touch screen also recognizes the touch in a glove. Still, as in the case of IR technology, you need to have regard to the casual touch, and as a result a misstatement. However, the sensitivity of this technology is lower.

EQUIPMENT - POWER - SPEED - CAPACITY

In this group of parameters you can choose what you want to with the Panel PC or the video card, SSD or HDD, RAM and processor.

Graphics card

	nVidia graphics chips are among the best in the world. Perfectly cope with even the most demanding applications. With the power of NVIDIA® CUDA ™ technology and the new CUDA runtime for Windows, programmers can now offload the most intensive processing tasks from the CPU to the GPU, delivering incredible performance improvements over traditional CPUs. HybridPower ™ technology delivers graphics performance when you need it and low power consumption of the remaining time. And with PureVideo HD engine next-generation, low quality Blu-ray becomes the past.
Graphics cards AMD Radeon ™ offer better performance compared to integrated graphics, which allows for faster execution of tasks / finish work and smoother operation and better looking games. Applications and games on your notebook deserve the best available performance and visual effects of time without sacrificing battery life.
	Intel® HD Graphics - an amazing visual effects and 3D images. Regardless of whether you're playing games, editing a video recording or watching movies, Intel HD Graphics includes powerful features to ensure a smooth, stunning 3D visual effects: Advanced technologies improve productivity and efficiency. Faster display of 3D content and more complex features, shading provide incredibly dynamic and realistic experience in 3D games. The layout of the Intel HD Graphics 4000 is capable of playing the popular and advanced games at a level similar to the basic external graphics cards - no need to purchase add-on card or layout. An Intel HD Graphics 2500 allows you to play the popular and internet games without having to purchase additional card or layout.

Drive type

There are only two types of SSD and HDD. The following is a characteristic of both drives. SSDs are different from traditional HDD by many factors such as the strength of the shock, the speed of reading and writing, and above all price.

SSD (ang. Solid-state drive, sometimes solid state disk) - storage device built with flash memory. The main advantage of SSD is the lack of moving parts. In addition, these drives have a far shorter time access to data (several times), quieter and much more resistant to mechanical damage (caused eg. Vibrations during operation or falling from a height). Another issue is the use of SSD in industrial computers, where there is significant large capacity as is the case with traditional HDD, but above all, reliability and resistance to vibration. SSD in industrial applications do not require the capacity of 50-100 GB, because in practice are used in capacitance of 512MB-8GB and it is enough that at a relatively low cost of memory do its job.

HDD (Hard disk drive) - the type of storage that uses magnetic media for data storage. Disk HDD type consists of a plate or disc assembly for aluminum alloy coated with a thin layer of magnetic media and electromagnetic heads that allow reading and writing of data. For each disk platter accounts for a pair of heads - one head and one read-write. The data are stored on the disk platter by sending electromagnetic flux through the recording head. Hard drives are the most important the following parameters: capacity, data rate, data access time, speed magnetic disks (rev / min.) And the mean time between failures (MTBF).

RAM Memory

RAM Memory is very important and one of the basic computer components. This is the place where the computer temporarily stores the individual data. The more memory you install on your computer, the more programs will be able to run at the same time, which will run more efficiently. RAM is important for the performance of your computer. Of course, in the context of memory has not only its size, but also the operating parameters.

What are the types of memory?

There are several types of memory, but now they are the most important:

• DDR 2
• DDR 3

What kind of memory you can install on your computer, it will depend on the motherboard (although you can meet up with models that allow both installation DDR2 and DDR3 - but they can not be used simultaneously). Since it also depends on the amount of memory that is how many GB can handle up to and how capacious may be a single unit.

The main differences between DDR2 and DDR3:

The current DDR3 SDRAM memory chips are manufactured in 90 nanometer manufacturing process, and standard supply voltage is 1.5 V. them require DDR2 standard of 1.8 V.
DDR3 memory modules have 240 pins, which is the same number as DDR2. However, the memory controller designed to support DDR2 DDR3 can not handle, and a few pin DIMM has changed its meaning. For this reason, it is impossible to insert non-compliant modules - eg. The modules DDR3 DDR2 DIMM connectors.

Processors

The major manufacturers of processors are AMD and Intel.

The processor is the most important component of any computer, which is responsible for all arithmetic operations. For this reason, it is an intermediary in the performance of the processor, in principle, all tasks on the computer. Its quality depends on the performance of our system, and thus - the same comfort. It should be noted that the processor is a complex system, which is the building block of silicon. It has a small size, but it is a great computing power. Due to ongoing minimization on a small area of the chip can now hold millions of transistors, which gives the power, which is something we could only dream of. Not everyone needs the best and most modern computer processors.

Processors INTEL

With the advent of the first generation Nehalem processors (ie, the first Core i) in autumn 2007 completely changed the line and file naming convention Intel products. Since then, no need to know during the stamps: just look, whether it's a Pentium, Core i3, Core i5 and Core i7 to know about a product with which you are dealing. This simple move how much easier choice and strengthened brand: from now on, even the average computer user oriented knew better than to have a Core i7 Core i3. But this knowledge is not all: in every family there are several dozen processors, a number of different parameters.

Processors AMD

AMD is the second largest producer of processors based on the x86 architecture and one of the largest manufacturers of GPUs.

Bulldozer microarchitecture is a real revolution in the approach to the design of AMD processors. The main component is a module, which accounts for two units for the calculation of the fixed-point and floating one. In the simplest terms: in games such processor (eg. Czteromodułowy ośmiowątkowy FX 8150) behaved like a quad and multi-threaded programs - as ośmiordzeniowy. Support for fast DDR-1866 and high default clocks helped make up for deficiencies resulting from low IPC.

Resistance IP Degrees of IP is a classification of different degrees of protection of electrical equipment that are provided by enclosures of these devices according to PN-92/E-08106. A number after the "IP" is really two digits. The first is protection of human and animal access to hazardous parts and protection against contamination, such as dust. It's mainly about access foreign objects to enter the unit. The second digit is a degree of protection against water.   Pierwsza cyfra [x] Ochrona przed ciałami stałymi   Druga cyfra [y] Ochrona przed płynami No special protection 0 0 No waterproofing Protection from solid objects greater than 50mm in diameter 1 1   Protection from dripping water Protection from object not greater than 12mm in diamete 2 2 Protection from vertically dripping water (tilted up to 15°) Protection from object not greater than 2,5mm in diameter 3 3 Protection from sprayed water (tilted up to 60°) Protection from object not greater than 1mm in diameter 4 4 Protection from splashed water Complete protection against contact, Protection against dust deposit 5 5 Protection from water projected from a nozzle Complete protectionm against contact, Protection from infiltration of dust 6 6 Protection against heavy seas, or powerful jets of water     7 Protection against immersion     8 Protection against complete, continuous submersion in water

The video data is transmitted using the TMDS technology. The maximum transmission distance is 15 meters, using wires made in accordance with the recommendations of the HDMI Working Group.
	DVI (ang. Digital Visual Interface) - a standard connector between the graphics card and the computer monitor. DVI connector is present in 3 variants: DVI-I - carries both digital data and analog. After an appropriate adapter, you can connect with ordinary D-Sub connector graphics card. DVI-D - transmits only digital data; Some graphics cards have the ability to transmit audio via DVI, this is not compatible with DVI - abnormally used only some of the pins, which allows the use of non-standard DVI → HDMI. DVI-A - transmits only the analog data.
	DisplayPort – universal digital interface. The main aim of the new standard is a combination of computer-to-computer-monitor or home theater system (including projectors, large displays, TVs, etc.). DisplayPort connector supports 1 to 4 transmission lines transmit audio and video at a rate of 1.62 or 2.7 Gb / s (up to 10.8 Gb / s with four transmission lines). Standard enables simultaneous two-way exchange of information.
	eSATA (external SATA) port is an external SATA 3 Gbit / s, designed for connection to external storage. The main idea is to provide the same eSATA data transfer speed external devices, which is achievable for internal drives. Achieved by this standard speeds do not differ from those offered by SATA II - maximum throughput is 150 MB / s and 300 MB / s.

COMMUNICATIONS SYSTEMS

In this group of parameters we can choose the corresponding communication systems in which our Panel PC.

	3G does not focus on voice services. In addition to these providers offer the ability to quickly transmit various types of data (video, packages, photos). Europe's most popular 3G technology UMTS, or Universal Mobile Telecommunications System. Initially, UMTS provide download speeds of up to 384 kb / s (version R99). Standard is still being developed, which resulted in the implementation of family HSPA (High Speed Packet Access). Two technologies are also used in High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA).

The signals from the satellites transmit coded time and geographical data, which allow the user to precisely determine its exact position, speed and time anywhere in the planet.

AC POWER SUPPLY VOLTAGE

In this group, we can choose the parameters of the inverter's range, which is to support our Panel PC.

Panel PC support different AC voltage ranges. For industrial applications it is sometimes essential. The devices operate at different tasks and use very different voltage for proper operation. That is why such importance is an appropriate choice for the correct voltage power supply, so that the computer can work in an environment in which it is to be mounted.

Panel PC may be used for transport by adapting it to operate with a supply of 12V,  8~28V and 9~30V . Then the mini computer can be used in cars, buses, trams, taxis, trains and even airplanes. Very well suitable on its functions in vehicles in which it is important to the small size of the computer.

TYPE OF SCANNER

Readers (scanners) - types

Barcode scanners also known as readers, are used to automate the process of entering data into a computer system and for direct sales.

There is a whole range of devices for reading the printed barcode. Most readers not only reads the bar code, but also recognizes the pre-standard. This allows the same reader can read different codes in a number of different standards.

The new generation of wireless scanners allows you to read all kinds of barcodes, even with low-quality printing. The fact that they are wireless devices frees the operator from having to stand at the desk, so you can easily navigate through a large area and easily read codes from labels of various products.

Scanners not only reads the data stored in the bar code, thus eliminating the need for manual data entry and reducing the number of errors, but also ensure the automation of the processes associated with paper documents, eg. Stock management.

Readers CCD - A charge coupled device (CCD), also known as an LED scanner, features hundreds of tiny LED lights arranged in one long row. These lights are shot directly onto a barcode, and a sensor then measures not the reflection, but voltage of the ambient light directly in front of each lightbulb. This voltage measurement provides a digital snapshot of the barcode. CCD units can be very expensive, but are highly accurate and versatile pieces of equipment.

Laser Reader- Slightly more advanced than a pen scanner, a laser barcode scanner is capable of more exact light readings which prevent false positives or scanner errors. In a laser scanner, a laser beam is shot at a mirror inside the actual unit. This mirror makes a movement so that the laser sweeps across the barcode in a straight line. This light then reflects back to a diode, which measures the level of reflection. This reflection is translated into a digital signal readout of the barcode. Laser scanners can either be mounted in a scanning unit or be part of a handheld unit. 

Readers 2D - Some barcodes do not consist of white and black bars, but white and black spaces in a two-dimensional (2D) target. These 2D barcodes cannot be read by standard machinery, but they do allow for versatility of information coding as they can hold and provide much more data than a standard barcode. To read these barcodes, a 2D camera image scanner is necessary. This camera consists of hundreds of tiny lights like the CCD scanner, but these are arranged in multiple rows. The lights flash onto the barcode and take a digital picture of the barcode, which is then sent to software as a digital signal. The software then decodes the information.

Multi-line (omnidirectional) - scanner models often can be found in supermarkets and hypermarkets. They are really laser versions, which have more of the laser line, allowing you to scan 1D code from different angles. Some models may contain more than 100 laser line. This makes it possible to read data from virtually any angle.

DIMENSIONS

In this group, we can choose the parameters corresponding to the dimensions of our computer:

- length

- width

- height

This allows you to accurately find the equipment that meets our requirements for its size and even volume.

WEIGHT

In this group of parameters we can choose what weight range is to have our Panel PC.

The industry plays an important role weight devices, which are used in different places. Sometimes computers are assembled at different production lines where small rozmary and weight are an important factor for their proper selection.

Determine the weight range greatly facilitate search choice that meets your expectations in particular, corresponding to its use in the plant.

ADDITIONAL INFORMATION

In this group of parameters you can select additional options that you have to have your Panel PC, such as Wake up for a LAN or Watch Dog Timer.

Watch Dog Timer (WDT) – device or program, the most common electronic system for the detection of malfunction of the system, trying them - without human intervention - to repair and prevent serious accidents.

The principle of operation

The watchdog is a timer waiting for confirmation of the correct operation of the controlled device at a specified time. No confirmation is considered as an error and corrects it by restarting frequently, rarely unmaskable or momentary interruption of the power supply.

It comes in two main types: hardware and software. The hardware is much more reliable, and the software is more powerful. Eg. If the problem is caused by a memory leak, software responds to the insufficient amount of free memory giving you time to smooth shutdown without data loss and hardware reset brutally after suspension system, while the hardware much better cope with undefined interference, eg. From the power supply and protects against errors before the system starts.

The software is placed in a setter counter value to a baseline. Over time, as measured by independent CPU clock, the counter value changes - usually decreases. If it reaches a certain value, it is typically 0, there is described reset the processor or the corresponding interrupt is generated. One of the objectives of the correct operation of the system is to set the watchdog time to time the counter value to the initial value. This feature is placed in the program so as to carry out at intervals shorter than the time of reset. If the program to stop working correctly - eg. Enters an infinite loop or will be jamming and will set the counter again - it can be assumed that the restart is justified. In this way, the watchdog protects the system from unexpected cessation of activity.

Application

Watchdog is installed in the system, which often work without human handling, their continued operation is very important or unexpected effects can be dangerous. Are standard in embedded systems operating in different devices.

Some operating systems provide mechanisms to prevent a crash (blockage) of the system in the event of a fault (kernel panic) and support software and hardware watchdog software such as Linux watchdog package.

HEATING AND COOLING SYSTEM

The installed heating system available in the device ensures the stable operation of the standing totem by maintaining the same temperature. The mechanism of action is based on heating the device from a temperature of e.g. -30 ° C to -10 ° C, in which the device is functioning properly. The system is recommended for moderate or transitional climates in order to optimize the operation of the standing totem.

A heat exchanger is installed in the device to cool the device at high temperatures, so that the outdoor totem can function in heat and sun. The cooling system allows the display to work properly in summer and the ads will be visible. For example, if the device starts to heat up to a temperature of 60 ° C, the mounted fan, by increasing the speed, will cool the totem to a temperature below 50 ° C, thanks to which the device will be able to function properly.
