OPERATION Locating and Isolating Cables：

Using MT-7028 Networking Tone & Probe kit to locate and insolate cables using the 1KHz analog, also trace twisted wires (UTP, STP, Cat 5e, Cat 6) and telephone line (Cat 3). Use with a patch cord for RJ45 / RJ11. Coaxial cable, general cable and various wiring boards can be tested by using with alligator clip cable.

Warning

• It is not intended to be used on live wires with a DC

power source (e.g., live telephone lines), nor will it work on wire pairs that are carrying AC signals.

• Use RJ45(8 pin)/RJ11(6/4/2 pin) compatible connector

for RJ45 cable tracing. Use RJ11(6 pin) connector for RJ11(6P/6C/4C/2C) cable tracing. Use RJ11 (6 pin) connector and work with alligator clips for coaxial cable, general cable and various wiring boards.

Caution

• To locate and isolate cables using the 1KHz analog

toning mode, please avoid interference sources like electronic devices with adapter, induction coil, and motors nearby. White noise from MT-7028 Receiver is normal when your Transmitter is near any of the interference. If you cannot locate the signal on 2-conductor cables, the cable may be shorted. Please keep away from the interference sources or turn off the electronic devices.

• The position on the MT-7028 Transmitter and Receiver

lets you use the Receiver to trace using an analog 1KHz tone. When using the Receiver to isolate the tone source in the cable bundle or at the patch panel, the signal might be interfered with or decreased and the signal will not pass through metal tubes.

• It is not necessary to touch the Receiver’s tip to the

cabling or patch panel when searching for the Transmitter’s signal.

• Make sure the black alligator clip of the Transmitter is

connected to the ground before use.

MT-7028 Transmitter provides two 1 KHz analog toning modes, Hi/Low two-note tone, for location and isolating cables. Both toning signals are available at all connectors on the Transmitter.

Function

To locate cables, do the following steps (Figure 3)：

1. Connect the black alligator clip of the Transmitter to the ground, and then connect the red clip to a jack or punch-down block as shown in Figure 3.

2. As the Figure 3 shown, when push

, the indicator of

“POWER/ BAT LOW” will light up and turn on the power. Push

button for cable tracing. When the RED

indicator flickered, the low-tone cable tracing is working. Push

button again to feature the high-tone cable

tracing, the RED indicator will flicker faster. Push button again, the RED indicator will be stopped and standby for next operation.

3. AS the figure 3 shown, push “

” on receiver to operate cable tracing function. The tracing sound will be output from speaker. When put on earphone, there will be no sound from speaker, but from the earphone.

4. Use the Receiver to find the general location of the tone at a cable rack, patch panel, or behind a wall. In locating mode, the Receiver’s LEDs light up in red from 1 to 8, then wrap back and light up from 1 to 8 again as the signal strength increases.

5. Adjust the Volume Control on the Receiver to locate the wire pairs from 10cm to 30cm.

Isolati

ng Cables:

To isolate the tone source in the cable bundle or at the patch panel, do the steps as described in the previous section of “Locating Cables”.

1. Strip the cable’s shield to a length of between 30 to 45 centimeters and divide the wires into two parts. Do the wire separation to isolate the cables to verify the signal of each part. If the beeper gets louder and LED lights up, you have located the position you are looking for.

2. Adjust the volume control from high to low to enable looking for a more difficult to identify wire. Narrowing the length from 30 to 10 centimeters will help to more accurately identify the wire pairs.

3. Repeat the steps of 6 and 7 to isolate the bundled cables.

Caution

• If you cannot locate the MT-7028 signal on 2-conductor cables, the cable may be shorted or opened. Use the Continuity Test (Fig. 8) to check for shorts or opens on coax and non-terminated cables.

Caution

• When use the product for RJ45 or RJ11 cable

mapping, please only plug in the cable to RJ45/RJ11 compatible connector on transmitter. Do not use RJ11 (6pin) connector.

• You can use the MT-7028 Transmitter or Receiver

to validate the cable map on RJ45/RJ11 by RJ45/RJ11compatible connector on transmitter. The cable map function finds the most common wiring faults on twisted pair cabling: shorts, opens, and crossed pairs.

1. Connect the MT-7028 Transmitter or Receiver to RJ45/ RJ11 jacks.

2. Push “

”, the indicator of “POWER/ BAT LOW” will light

up and turn on the power. Push “

” on MT-7028 transmitter for cable mapping and shielded function indication. When the green LED indicator flickers slowly,

the low speed scan is working. Push the “

” button

again, the green LED indicator flickers faster and the fast speed scan will be operated. Push the “

” button again,

the product will be standby for next operation.

Caution

• Each LED that corresponding to an active pin flashes

briefly, and then should light for about 1 second. For fast scan cable mapping, the light will be flicker about 0.5 second, from 1 to 8, G. If the cable is open, the LED indicator will not light up.

• Before cable map testing, repeat the procedures of

“Locating Cables” on page 7 to identify the correct connector or wires on the other end of the cable if necessary.

4. You can use the MT-7028 Transmitter and Receiver to validate the cable map on RJ11 and RJ45 connectors. The cable map function finds the most common wiring status on twisted pair cabling: good, shorts, opens, and crossed pairs as shown in Figure 7.

• Good wiring: Each LED that corresponding to an active

pin flashes briefly and in a stairway order.

• Shorts: If two LEDs turn on for 1 second at the same time,

those two pins are shorted together. If more than 2 wires are shorted together, the LEDs for the shorted pins indicate opens.

• Opens: If an LED flashes briefly, then no LEDs turn on,

that pin is open.

• Crossed pairs: If one LED flashes briefly, then another

LED lights for one second, the wire for the first LED is crossed pairs to the pin for the second LED.

5. Each LED that corresponds to an active pin flashes briefly, it should light for about 1 second. The brief flash shows which LED is next in the sequence.
