Taking network test as an example: after entering connection test function,
press “ENTER” key to check wiremap. At this time, the following interface is
shown indicating test is in process:
a.Cable line-to-line test:
Test result 1: Short circuit
Short mapping:
1 2 3 4 5 6 7 8
Cable open or
too Short
1 2 3 4 5 6 7 8 G M:
R: 1 2 3 4 5 6 7 8 G
Wire Map: Remote
If there is short circuit with the cable and terminal, it will show as below:
(Short circuit with 3 and 6)
At this time, press any key to return to the main menu, and then press
“ENTER” key for re-test.
Please do not perform test again until short circuit problem solved.
Test result 2: if the far end of the cable to be tested is not plugged in
remote adapter (R) or cable is not plugged into the local port (S),
the following interface is shown:
Test result 3:correct connection
the following interface is shown :
“M”stands for Master unit. “R” stands for remote unit.
Test result 4: In case of open circuit existing on far end of the cable,
the following interface is shown:
1 2 3 X X 6 7 8 M:
R: 1 2 3 X X 6 7 8
Wire Map: Remote
In the figure, “X” shown in “4” and “5” pin position, indicates there is
open circuit in “4” and “5” pin of the remote pin.
