Different computer documentationThe review of panels DU for the computerWhat should be the modern computer? This question worries not only vendors of computer "iron", but also principal software developer the company of Microsoft which already equips today multimedia computers sold under the trade mark with remote control units. But what to do to a domestic customer which does not allocate an appropriate amount of "evergreen"? Certainly, it is possible to try to replace panel DU of an IR-keyboard or the mouse about radio- or an IR-interface. But an IR-keypad - a thing specific enough: at first, it does not replace the normal keypad and they should be had both, and secondly, keypad overall dimensions do not come within miles of panel overall dimensions and consequently it to use less conveniently. As to the radio mouse, at first, it not so operatively, and secondly, is required to it a horizontal surface besides to aim the cursor in small buttons on the screen - not the most convenient occupation. There is a unique way - in depths of the Internet on searches of the suitable circuit. After long searches and ordering of the found circuit variants of implementation of the device of reception of an IR-radiation simple circuits in manufacture have been selected and tested some. During tests the circuit possessing the greatest sensitivity is revealed. The applied radio components: IR-receiver TSOP17xx with pressure of a supply 5В, the resistor resistance of 3,3 clods, a stabilitron 5,1В, the condenser 0,1мкФ. The applied details are accessible at the price and can be acquired on a radio market. IR-receiver TSOP 17xx can be replaced on domestic, manufactures НПО "Integral" ILMS5360, but it is not desirable, as it has the considerable dispersion of parameters, and the device collected on its basis can work not stablly. The circuit is very simple in the assembly and does not demand adjustment. As the device driver the software from a site http://www.girder.nl/ or http://www.lirc.org/ can be used free, in the second case it is necessary to replace resistor R1 with the resistor with resistance 4,7кОм. A simplicity and cheapness Underside was that drivers to circuits without DSP consume a lot of processor time at the moment of signal reception as for steady determination of an IR-code it is required that signal decoding was fulfilled by the processor in a real time mode. And it means that during such moments the computer will brake, subjective value of "brakes" practically is not noticeable at processor Duron usage 700MHz in idle to a course but if loading on the processor makes 80 % and more "brakes" will be felt and at processor Athlon usage 1.7GHz. The second minus are temporal expenses for learning of the volume documentation and the subsequent adjustment of the driver. But the most important minus appeared that there are no warranties that the device collected by you will work faultlessly. So, at serial setting on 8 machines of a various configuration the following result has been received: on five computers the device worked well, on two it worked not stablly, and on one at all did not submit life signs. On the other hand, such result can be quite recognized satisfactory, after all at expenses about 2 c.u. the probability of good result makes 63 %. Thus it is supposed that: panel DU already is available, expended time in calculation does not undertake. Also it is necessary to mark that usage of available panel DU can appear inconvenient, for example, if the technics controlled the panel and the computer are in one location that case when they will respond together to commands from the panel is possible, or, on the contrary, at technics and computer finding in different locations the perspective of search of the panel does not inspire. Thus, we come to a conclusion that it is desirable to acquire separate panel DU which increases convenience of use, and also device cost (on 3-4 c.u.) which makes as a result of 5-6 c.u. Considering the increased cost, complexity of adjustment and that operation of the device collected by you after motherboard changeover can appear in doubt, we come to a conclusion that all not too радужно as it seemed at first sight, and this way is comprehensible only to the present enthusiasts. And what to do by that who does not want to face the enumerated complexities, but has desire to receive from the computer the maximum service including remote control by it, let even spending for it not 5-6 c.u., and 10-20 c.u.? As it appeared, for any inhabitant of the CIS, including Belarus, this question - "not a question" as it has a possibility to acquire the remote control unit computer IRman. On a site irman.at.tut the whole ruler of remote control units from IRman I to IRman III + is presented. What can they? And they can very many - to regulate loudness, to launch and stop reading of stories, playback of music, films, to rewind tracks, подматывать a current track, to regulate brightness, visibility, a saturation, an image shade at review of films, to launch and close applications, to ungear the computer, to assign keyboard abbreviations on any actions. For example, loudness regulation: Win + Alt + Up/Down (more loudly/more silently) to open/close the calculator button NumLock etc. And it is only small part of their possibilities. At presence TV - or FM-tuner IRman can control and them - to switch channels, modes etc., allowing to spare the order of $20 on the tuner, acquiring it without the panel. With its help the computer turns to the real multimedia center! Besides, IRman it is possible to use for control of various programs, adjusting it under the specific needs, for example, it can replace almost any panels for computer hardware. In the presence of a local network it is possible to control other computers on a network. A frequent situation in firms - the big room, in it some computers united in a network, and are connected to one of them of a column, music sounds, the person near to this computer is not present, and phone here rings... There is a possibility to regulate loudness of music from the workplace. And it not all... All control is carried out by means of the panel and accompanied by display to the screen of the monitor of appropriate menus which allow to be guided easily and simply in an event (on insert screenshots are resulted and some possibilities) are enumerated. From all ruler IRman'ов most functionally saturated is IRman III +. Except described above, it gives possibility to turn on the computer from panel DU, and also can not only accept IR-signals, but also play back them. At switched on computer IRman III +, being the general-purpose panel DU, it is capable to control equipment of various firms, replacing some panels simultaneously. This ability IRman III + will be estimated, first of all, by fans of a good sound at whom it is deduced on the exterior amplifier (musical center) remotely operated. Work IRman'ы under any versions of "windows", since Win98 and finishing WinXP, the interface of connection RS232 (Com port), USB. As they say, for all tastes - everyone can select that is necessary for it. At acquisition more than one set is given discounts, and the registered users have possibility to update a software through the Internet during guaranty period. The device, panel DU, batteries enter into a set to the panel, a compact disk from a software. Some possibilities IRman Video control. After an insertion of a compact disk with a film in CD-ROM or DVD-ROM all remaining actions are produced from the panel. Brightness, visibility, a saturation, an image shade, picture approach/removal, switching of image formats is regulated, etc. At navigation on a film are accessible подмотки in both directions, a jump in the specified position, storage of current position with possibility of the subsequent reset. |
