-duplex communication circuit3 Frequently Asked questions in the application3.1 Anti-Lightning and antistatic shockThe RS-485 interface chip may be damaged by static electricity when used, welded or transported in the equipment. When the transmission line is erected outdoors, the interface chip and even the whole system may be struck by lightning. The use of antistatic or anti-lightning chip can effectively avoid such losses, the common chip has max485e, max487e, max1487e and so on. Especially w
machine, Electrostatic printing machine... .Press can be roughly dividedFlat Press press, Flat Press, direct circular press, indirect circular Press.According to the number of ink, the printing machine can be divided into monochrome printing machine, two-color printing machine, four-color printing machine, five-color printing machine, silk printing machine.Depending on the size of the printing area, the printing press can be roughly divided into full
Magnetic BeadsIt is designed to suppress high-frequency noise and Spike interference on signal lines and power cables, and also to absorb electrostatic pulses. Magnetic Beads are used to absorb ultra-high frequency signals, such as RF circuits, PLL, oscillating circuits, and ultra-high frequency memory circuits (ddrsdram, Rambus, etc.). They need to be added to the power input part, inductance is a type of energy storage component used in LC oscillato
video, such as descriptions of internal switches, logo technology, and Electrostatic Protection of the fuselage, it will lead to serious deviations in the understanding of this product. Such errors should not occur for a team that is evaluated as a professional. Secondly, we must apologize for the inaccuracy in the video footage and the possible misleading reasons. The video concluded that the video angle is based on the test results of the darkroom.

recognition speed slows down. The unique recognition speed of voiceprint algorithms has nothing to do with the number of people. Each recognition time is less than 1 second. Device vulnerability: The fingerprint optical contact surface is easy to wear, the silicon contact surface is vulnerable to electrostatic damage, the equipment is vulnerable to malicious damage, and the use and maintenance costs are high. Voiceprint sound is not vulnerable to dam
frame, forming a red outer network on the screen surface. When you touch a certain point on the screen with your fingers, the system blocks the two infrared rays passing through the position, and the computer can instantly calculate the position of the touch point. The infrared touch screen is not subject to current, voltage and electrostatic interference and is suitable for some harsh environmental conditions. Its main advantage is its low price, ea
, such as the paper [the output path contains sundries, paper roller and other parts of the rotation failure, paper tray, sensor failure, such as to eliminate the fault of the method is very simple, just open the cover, remove the card can be, but note that you must press the direction of the paper to get paper, can not turn any knob in the opposite direction. If you frequently have a paper jam, check the feed channel, clear the clutter of the output path, and the front edge of the paper is ju
motherboard connection damage. Replace the power supply attempt to exclude the second possibility; Please check the motherboard exception, such as whether there is a capacitor bulge (was penetrated), the motherboard surface has no obvious damage to the line, etc., you can get the repair station under inspection, conditional words can be replaced by a motherboard to determine. Finally, I remind friends to pay attention to our computer fan and electrostatic
chassis leakage. Second, the chassis leakage is what reason? There are two cases of leakage of the chassis, one is the long-term rainy, humid air so that the chassis electrostatic voltage is too high, the hands of the feeling of electricity! This situation, as long as the attention to strengthen ventilation, to ensure that indoor air as much as possible to dry bath, timely cleaning up the box inside the ash, especially the motherboard a
protection Board can be. Step four: Test capacity The final step is to detect the memory of the notebook card most, the method is very simple, first need to enter the notebook BIOS, let the BIOS first identify the memory, most notebooks are on the boot press F2 key (on the boot will be prompted, or reference manual) into the BIOS. When you reboot and boot into the system, you can see the memory capacity in the General tab by right-clicking the computer or My computer.
Random fault is a common fault encountered in the process of computer use, due to the failure of the crash is uncertain, the nature of the operation is not fixed, and the crash occurs, the phenomenon is not uniform, so the scope of the fault occurred is not easy to determine, to repair work brought a certain degree of difficulty. According to a large number of maintenance cases, the reason for the random crash failure is mainly as follows: three. I. Environmental factors Environmental factors h
-hand, repair goods and work bags. Graphics cards, sound cards and other board products, most of the business because of the need to label, packaging boxes and electrostatic bags can be opened casually, although it is convenient for us to watch the goods, but also convenient for businesses in this area. If we are looking for a product and are sure to buy it, we first need to check their golden finger parts to see if there are any traces of metal rubbi

Step 7: Draw logo and synthesize Finally, the logo part of the drawing, ideas and the way described above. Let's just say the shaded part of the logo, because there will be shadows in the drawing process, such as the fox's collar and sleeve parts. Electrostatic treatment of the following ideas: Why not use the sketch Sh
installed, in the installation of video cards, memory will be squeezed downward, then it is easy to damage the motherboard. 2, motherboard fixing screw washer function is not small, can prevent the screw directly contact the motherboard and lead to the motherboard and chassis contact short-circuit problem, but also can shield some motherboard and chassis floor electrostatic and electromagnetic interference. second, various types of data lines, po
