Note: Because netw ork cable is made of pair cores, if there is open circu it,

it will show faults in pairs, just as above "4" &" 5". it means eit her "4" pin

or "5" pin exsits an open circuit , or bo th "4" and "5" exsit an open circuit.

Test result 5: In case of open circuit existing at the near end of the cable , the following interface is shown:

In the figure, “X” shown in “3” and “6” pin positi on in “M” line, indicates there is open circuit in “3” and “6” pin of the near pin.

Test result 6: In case of open circuit existing at the middle part of the cable , the following interface is shown:

In the figure, “X” shown in “3” pin positi on in “M” and “S” line, indicates there is open circuit in “3” pin of the middle part of the cabl e. Perform"Cabl e Length" to locate the exact fault point. Ref er to the related chapter below.

Remote unit with tone when checking wiremap

When use rem ote un it to check wiremap, users can distingus h the test result firstly via tones. When the cable is normal , the remote unit will generate “ beep ” long and slowly. When the cab le is abnorma l, the the remote unit will generate “ beep ” sh ort an d quic kly.

Special use:

In case of exchanger power-on, the main unit

can test line sequence of the connecting cables

Take network cable as an examp le: one end of the cable is connected with “MAIN” interfa ce of the main unit, and other end is connecte d with exchanger interface. And direc t connection test can be perfor med. If the exchanger inter face tested is reliably con nected, the followi ng interfaces shown (ex changer interfa ce is 8-core):

Shor t ma pping:

1.Trac ing cable (RJ 45/RJ11 Cabl e) which is conne cted to switch or router.

Insert the cable into port RJ11/ RJ45 (S), Press the testing key of receive r, “P ower” will be lighted, then hold the recei ver close to the cables, when the probe get s close to the targeted one, you can hear clea r and loud “beep,beep, beep ” . (Note: telephone cab le into RJ11, Lan cable into por t RJ45(S) )

2.Trac ing Coax cabl e

Insert the cable into port BNC , Press the testing key of receiver, “Pow er” will be lighted, then hold the rec eiver close to the cables, when the pro be gets close to the targeted one, you can hear cle ar and loud “beep,beep, bee p” . (Note: turning dow n the voice slowly help trace cable eas iler. )

3.Locate th e short or breakge p oi nt (eg: metal l ine)

Connect the metal line wit h the cable clips, press the testin g key of re ceiver, hold the receiver close to the cabl es, “beep, beep,bee p” will generate, but when the probe targets the brea kge point, “beep,be ep,beep” stops, whi ch indicates that is where the breakage is. Note: 1) the metal line is de-ene rgized.

2) Tur n up th e voice, which helps locate bre akge easily.
