Q:Ipad charging display does not support this accessory
Ipad charge display does not support the general reasons for this and processing methods: . for non-original charger, it will often appear this situation, which is due to the charger does not meet the specifications caused by the replacement of a qualified charger can be. . if the original charger appears the above failure, please continue to look down. . please check whether the data line is normal. The appearance of the data lines seem normal, which may have been broken. Check the method is to borrow someone else's data line to see if it can charge. . shows the plug symbol is normal is full of display. If full or show the lack of electricity, indicating that the phone tail no problem. . again, check whether the original charger can work properly. You can connect the charger to other USB port to see if the phone is working properly. . if the above two check still can not charge, please try to insert the computer's USB port to see if the computer can identify the phone, to identify if it is to see if the charge, if not identified but not charged, it is estimated that the need for maintenance. If you can not identify can not charge, it is necessary to repair. If you can recognize and charge, replace the data cable and the charger (the original estimate is also damaged). . and then look at the voltage is not too low, not only to the maintenance station to repair, and pay attention to the iPad and iPhone do not mix the power adapter, the voltage is different.
Q:How to distinguish between power cables and electrical wiring on drawings
Can not be removed, and so on after the first line of fluoride, and then demolition of air conditioning.
Q:Fiber optic cable split box, integrated wiring box, cable terminal box, cable transfer box difference
A lot of ways ah! You look at the back of the set-top box, a total of three kinds of interfaces, namely, HDMI digital signal (while transmitting audio and video signals), red and yellow and yellow chicken complex habit of glycosylation moxibustion slim faint handle (red is the right channel, white Is the left channel, the yellow is the video), the color difference signal (red, green and blue, only transmission video), S terminal (single hole four pin, only transmission video). You just put the video to the TV, the audio to the amplifier on the line. . if your amplifier does not have HDMI interface, then put the set-top box HDMI connected to the TV, the set-top box red and white two terminals, connected to the amplifier red and white input terminal, and adjust the amplifier to the appropriate channel The . if your amplifier has HDMI interface, then through the HDMI series on the line, the first amplifier or the first TV will do. . TV set after a lot of them, there is a group of AVOUT output interface, this group of red and white terminals connected to the power amplifier is also OK.
Q:What is the cable for rvv? Is it a power cable or a control cable? What is the cable?
Multi-core cable should be cable number, if not, should first use the table to find and put on the line with the tube.
Q:What is the difference between "wire" and "cable"?
Inkjet printer is not printed, pictorial machine high definition, generally used in the advertising industry, for large outdoor advertising, the nozzle can choose not necessarily the number of installed, the more spray, spray the faster, a nozzle of the general life 1 year.
Q:Connect the computer to the TV. The The Using the HDMI cable. The The Line no problem. The Why not even after the audio video. The The Amplifier is Denon 1311
Make a mark, such as red set into the bottom for a color in a layer, or you can draw a few plans, water and electricity is a strong power is a weak and one, the label can do a good job
Q:Where should the inner diameter of the plastic tube of the cable be at least the number of times the outer diameter of the cable?
Wiring room refers to the distribution of the weak floor of the room, the weak point refers to the building weak vertical pipe
Q:Galvanized wire tube buried to do anti - corrosion do
No need. Galvanized flat iron to do when the grounding grid is not anti-corrosion, but if there is welding or damaged place to become anti-corrosion.
Q:Wire and cable CCC product consistency is what
PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.
Q:Automotive wiring harness welding to pay attention to what the problem
5 small cable, if you feel high cost Can be from the distribution box to the circuit The first light using a small cable low-voltage bus to the equipment side, due to the power distribution room to the equipment side will appear more climbing, bus installation climbing very troublesome and affect the beautiful, The bus outlet cabinet uses cables and installs the transfer box on the busbar
