Network Cable Tester INSTRUCTION MANUAL

Read the precautions before your operation

• Please do not place the device in a location that is dusty, humid, or hot (above 40°C).
• Please use a battery that meets the specifications, otherwise the device may be damaged.
• Please do not disassemble the device. Repair and maintenance should be done by a professional staff.
• When not using the device for a long lime, please remove the battery inside the test terminal to prevent the battery liquid from leaking out.
• Please do not use this device to detect live power lines (such as 220V power supply lines), the device may be damaged and personal safety may be influenced.
• Please do not perform related operations on the communication line during thunderstorms to prevent lightning strikes and personal safety.

Overview

NF-8209 is a new generation to offer digital and analog signaling all in one network toner and probe. It has three modes for options to track cable like digital mode, analog mode and PoE mode. That means it’s equipped with the most powerful cable location technologies for any work environment. Also, it includes cable length measurement , cable faults testing, PoE testing, hub blink and NCV function, all these makes it a must-tool for cabling engineers.

Keypad display and features

Product Operation

Turn on the device and enter the below main Menu

1. CONT– Test open, short, cross ect for STP, UTP cable.
2. Length–measure length of Ian cable, range is 2.5m-200m.
3.  Scan–Analog/Digital/ PoE mode to locate Ian cables.
4.  PoE– available for standard or non-standard PoE switch (5-60V), identify AT or AF standard of PSE 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.

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, Press “OK” to start testing.
• If the cable is a good one, the result will be as below.

1. Possible results
   Only if a cable exits short circuit, no matter it exits cross, breakage or not, the testing result will only display “Short” information. If it doesn’t exist short circuit, then it would display what actually it is.

2. Cable Open
   If the LCD screen display “Cable Open!”, there are several reasons for this.

3. all the pins are open indeed.

4. no cable is connected.

5. the remote is not connected.

6. Connect with wrong port.

Length measurement
 Connect one end of cable to “Length/Port flash” port, disconnect the cable at far 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 exists problem at 12.1 m. 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 Ian 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 O meter.

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.

1. Attention: If the transmitters 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.
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.

PoE Testing

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 PSE(af or at standard).
   Connect the cable into “PoE” port, the testing result display as below image.

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 PSE, just display “Non standard”. Connect the cable into “PoE” port, the testing result display as below image.
   Attention : If all the 8 pins are providing power, it won’t display polarity.

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.

Port Flash & Switch details testing

• Connect a Ian 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 (1 0M/1 00M/1 DOOM), transmitting modes (FOX: full duplex / HDX: half duplex) Protocol (Auto-Nego / Non-Auto­Nego). See the graph for ref. as below. 

Setting

• Backlight setting
  Adjust the backlight time among 15s, 30s, 60s, on, and off.

• Auto-off time
  adjust the backlight time among 15mins, 30mins, 1 h, OFF.

• Contrast setting
  Press the left and right keys to adjust the contrast to suit yourself.

• Version information
  To check version information of software and hardware.
