USB extension line of insufficient power supply solution
1, when the purchase line should pay attention to buy standard instead of non-standard
2, decide for themselves their own needed wire diameter, here I said under thepersonal views:
Short distance <1> using low-speed, medium speed USB, USB, printer, camerabased (within 3 meters), the recommended standard of 0.5 square mm line
<2> uses high speed USB disk, mobile hard drives, cameras, TV box and other equipment, short distance (3 meters), the recommended standard of 0.75 square mm line
<3> uses high speed USB disk, mobile hard disk, USB2.0, printer, scanner and other equipment, long distance (3 meters -10 meters), recommended standardof 1 square line
<4> on the third point, if the distance is more than 10 meters, suggested a few lines to connect! That is, a plurality of line extension used in combination; for example: if the use of 12 meters, can do 4 or 3 root root 3 meters, 5 meters to12 meters to extend the line combination!
The number and position of 3, ring
<1> based on the linear, winding density, and hardware characteristics ofdiscretion, figure 2.5 meters I used 2 ring, in general, 3-7 meters need 4-6ring, 10 meters to the 10 ring, 12 meters still refer to a plurality of extended line combination way!
<2> self judgment, is not a bit fuzzy? The use of TEARCOPY copy speed,USB2.0 high speed USB copy 10G many movies and GHO files, speed is 26MB/S; another 5 meters I used 4 magnetic rings, copy speed is 32MB/S.
