Operation Menu for NF-8209 :
1.CONT-- Test open, short, cross,ect for STP, UTP cable.
2. Length--measure length of lan cable, range is 2.5m~200m.
3. Scan--Analog/Digital/ PoE mode to locate lan cables.
4. PoE-- available for standard or non-standard PoE switch (5~60V), identify AT or AF standard of POE type.
5. Flash--locate network port by the flashing port light on switch/ router.
6. Setting—Set Language, backlight time, auto-off time, contrast and version.
1. Continuity testing:
Connect one end of cable to "CONT" port of transmitter on the left side, the other end to the RJ45 port of remote terminal, Press "OK" to start testing.
2. Length measurement:
Connect one end of cable to "Length/Port flash" port, disconnect the cable for the other end, choose "Length" on the main menu, and select the preferred unit (meter/ yard/ feet ) before testing.
then press start to measure and the result will come out soon on the screen.
From the image, it means there exsits problem at 12.1m. To make sure it is short or broke there, you can test its continuity to know details. Kind reminds when measuring cable length.
1. the lan cable to be tested must be de-energized.
2. disconnect the cable at the far end, no remote, no other devices connected!
3. The range must be 2.5m~200m, otherwise, it would be display 0 meter.
3. Cable scan:
Connect the cable to be tested to "SCAN" port of transmitter on the left side, enter "SCAN" on the main menu, press ok to choose scan mode you prefer, the default is digital mode, the other modes is Analog & PoE. then set the corresponding
mode on receiver accordingly. After that, hold the receiver to locate cable at the other end, the loudest voice is the correct one.
3.1. Attention: If the tranmistter is in PoE scan and digital scan mode, the receiver must be in digital mode. the analog scan in transmitter matches analog mode in receiver. If the modes are not matched correctly, even the receiver touch the correct cable, it won't generate tone, either.
3.2. Non-contact voltage detecting: press the "Power/Set" button on the receiver, if the "NCV" indicator is lit on, then you can use the receiver to detect AC voltage presence
4. PoE Testing:
4.1 Standard PoE device
It can test the information of standard PoE device, such as POE voltage, power supply polarity, power supply mode and also the type of POE(af or at standard). Connect the cable into "PoE" port, the testing result display on the lcd screen.
4.2 Non-standard PoE device
If the PoE device is non-standard, it can also test POE voltage, power supply polarity, power supply mode, but it can't tell the type of POE, just display "Non standard"
4.3 If connected with PoE device, the result can be displayed after a few secs, it there is no result displayed after 30secs, then the device connected may not be PoE device.
5. Port Flash & Switch details testing:
Connect a lan cable to "Length/Flash" port on the main unit, choose "Flash" on the main menu to start testing. The 2 indicators on the "Length / Flash" port will be lit and flash. Then observe the ports on switch, if there is a port whose flash frequency is 3 secs, and slower than all the other ports, it tells you the port is the target one you're looking for.
Also, the device can tell you the connected switch’s information, such as its speed (10M/100M/1000M), transmitting modes (FDX: full duplex / HDX: half duplex) Protocol (Auto-Nego / Non-Auto- Nego).
