The merchant provides the correct method: General connection method: Orange White 1 orange 2 green White 3 Blue 4 blue white 5 green 6 brown white 7 Brown 8 Cross Connect Method: Green White 3 Green 6 orange White 1 Blue 4 blue white 5 Orange 2 brown white 7 Brown 8.

1. How to use: The Crystal head at both ends of the network cable plug into the main tester and the remote test end of the RJ45 port, the switch to "on" (s for slow gear), then the master tester and the remote Test side of the indicator should be shining each. (1) Pass-through connection test: When testing the pass-through connection, the main tester light should be from 1 to 8 sequentially shining, and the remote Test side of the light should be from 1 to 8 in order to flash.    If this is the case, the connectivity of the straight line is no problem, otherwise it will have to be re-made. (2) Staggered line test: When testing staggered lines, the main tester should be light from 1 to 8 in order to flash, and the remote Test side of the light should be 3, 6, 1, 4, 5, 2, 7, 8 in the order of flashing.     If so, there is no problem with interleaving connectivity, otherwise it will have to be re-made. (3) If the cable at both ends of the line sequence is not correct, the main tester of the indicator light is still from 1 to 8 shining, but the remote Test side of the light will be in accordance with the main test end of the line number connected to the order of flashing. In other words, the remote Test side cannot shine in the order of (1) and (2).

2. Wire Break test phenomenon (1) when there are 1 to 6 wire break, the main tester and the remote Test side of the corresponding line number of the lights are not lit, the other lights can still shine one by one. (2) When there are 7 or 8 wires open, the main tester and the remote testing side of the lights are not lit.

3. Wire short-circuit test phenomenon (1) when there are two wires short-circuit, the main tester of the indicator light is still in order from 1 to 8 shining one by one, and the remote test end two short route corresponding to the light will be lit, the other lights are still in the normal sequence of flashing. (2) When there are three or more than three wires short-circuit, the main tester light is still from 1 to 8 in sequence, and the remote Test side of all the short route corresponding to the light is not lit.
