One end of tested cable need to plug in NCT-500’s left port, and the other end of cable need to connect to
RT-80 data reflector or anotherNCT-500 which in reflector modal before you start the test.
Exp
Hint: You could not get correct test result when cable through any network equipment.
Impendence Test
The test is used for twisted pair transmission impendence. Standard twisted pair cable impendence is
100
Ω
When tested data is far above or under standard value, it indicates that network transmission signal will
produce reflection and damping. And it will affect network transmission accessibility.
One end of tested cable need to plug in NL-830’s left port, and the other end of cable need to connect to
RT-80 data reflector or another NCT-500 which in reflector modal before you start the test.
You don't need to turn on RT-80 data reflector
Exp
Hint: reflectivity a.k.a. Echo reflectivity which means the ratio of signal callback range because of
impendence mismatching.
You don't need to turn on RT-80 data reflector when using this program, but if you turn it on you must wait
until the LED indicators “1000M” and “DUP” flashed.
