Test 3: Normal wiring diagram (WIREMAP) display:
The LAN Network Cable Tester will automatically detect the far-end matcher (ID) or
local port (L) cable and it will display the wiring diagram (WIREMAP). If it finds the
far-end matcher (ID) or the local port (L) on the far-end of the cable being checked,
the display will show the following:
The ‘R:’ line shows the RJ45 jack pin number of the far-end port and ‘ID1’ is the
far-end matcher number.
The ‘|:’ line shows the connecting wire between far-end port and master port.
The ‘M:’ line shows the RJ45 jack pin number of master port.
Press the
p
or
q
key to restart the test or press the ‘PAIR&L’ key to return to the
main menu.
Test 4: Wiring diagram, (WIREMAP), display when there is an open circuit at
the far-end of the cable:
On the ‘R:’ line, pins ‘3’ and ‘6’ display ‘x’, indicating an open circuit towards the
far-end plug on pins ‘3’ and ‘6’. The open circuit should be located within 10% of
the cable length measured from the far-end plug.
Note:
If you use the far-end matcher (ID) to measure the wiring diagram (WIREMAP), because the
test is made via the paired cable cores, the open circuit at the far-end always displays in pairs,
as shown above. This is the case whether there is one open circuit or all are open circuits in
the far-end pins ‘3’ and ‘6’. For identification, move the tester to the far-end and repeat the
measurement.
