Using the Wiremap Adapter and Remote ID Locators - MicroScanner2

 

Terminating twisted pair cabling with the standard wiremap adapter or optional remote ID locators lets the tester detect all types of wiremap faults. Without this termination, the tester cannot detect crossed wires or crossed pairs. 

For a wire pair with one wire open, termination is required to detect which wire is open. 

Without termination, the tester shows both wires as open. Using multiple Remote ID locators helps you identify connections at patch panels. 

The tester shows the number of the locator connected to the far end of the cabling.

To connect a Remote ID locator to a modular (RJ) jack in a confined area or to a 4-pin modular jack (RJ11), use the optional universal adapter and a patch cord.

 

Using the Optional Universal Adapter 

Twisted Pair Test Results - MicroScanner2

To test twisted pair cables:

  • Turn on the tester.
  • If the tester is already on and in coaxial test mode, press PORT to switch to twisted pair test mode.
  • Connect the tester and wiremap adapter or ID locator to the cabling as shown in Figure below.

The test runs continuously until you change modes or turn the tester off. 

Note
You can measure length without connecting a far end adapter; however, an adapter is required for a complete wiremap test.

Twisted Pair Test Results

The following examples show typical test results for twisted pair cabling: 

Open on Twisted Pair Cabling 
Short on Twisted Pair Cabling 
Crossed Wires 
Crossed Pairs 
Split Pair 

Open on Twisted Pair Cabling
Figure 2 shows an open on wire 4. 

The three segments shown for the wire pair length indicate the open is approximately 3/4 the distance to the end of the cabling. The cable length is 75.4 m and is terminated with the wiremap adapter.

Notes 
If only one wire in a pair is open and a wiremap adapter or remote ID locator is not connected, both wires are shown as open.

The warning icon does not appear if both wires in a pair are open because open pairs are normal for some cabling applications.

Figure 3 displays the distance to the open, use UP ARROW or DOWN ARROW to view the individual result for the wire pair. In this mode, the tester continuously tests only the wire pair you are viewing. 

Figure 3 shows examples of these screens.

1. A Short on pair 1, 2 at 29.8 m.

Note
On the individual results screens, shorts are shown only when they are between wires in a pair. 

2. Pair 3, 6, is 67.7 m long and is terminated with the wiremap adapter. 

3. Open on pair 4, 5 at 48.1 m. the open could be on one or both wires.

Figure 3. Results Screens for Individual Wire Pairs

 

Short on Twisted Pair Cabling 
Figure 4 below displays a short between wires 5 and 6. The shorted wires flash to indicate the fault. The cable length is 75.4 m.

Note 
When there is a short, the far-end adapter and the mapping of the unshorted wires are not shown.

Figure 4. Short on Twisted Pair Cabling

 

Crossed Wires 
Figure 5 below shows that wires 3 and 4 are crossed. The crossed wires flash to indicate the fault. Cable length is 53.9 m. The cable is shielded and is terminated with the wiremap adapter. 

Detection of crossed wires requires a far-end adapter.

Figure 5. Crossed Wires

 

Crossed Pairs 
Figure 6 below shows that pairs 1,2 and 3,6 are crossed. The crossed wire pairs flash to indicate the fault. This crossed pair is likely caused by mixing 568A and 568B cabling. 

Detection of crossed pairs requires a far-end adapter.

Figure 6. Crossed Pairs

 

Split Pair 
Figure 7 below shows a split pair on 3, 6 and 4, 5. The split pair flashes to indicate the fault. The cable length is 75.4 m. 

In a split pair, continuity from end to end is correct, but is made with wires from different pairs. Split pairs cause excessive crosstalk that interferes with network operation. 

Detection of crossed pairs requires a far-end adapter. 

Note 
Cables with untwisted pairs, such as telephone cords, typically show split pairs due to excessive crosstalk.

Toning in IntelliTone™ Mode - MicroScanner2

Using the Toner

You can use the tester with an optional tone probe to locate cables in bundles, at patch panels, or behind walls.

Use the tester’s IntelliTone™ mode with an optional Fluke Networks IP100 or IP200 tone probe. The digital IntelliTone signal is easier to detect at a distance than analog tones, and its frequency and encoding eliminate cable misidentification due to signal bleed and radiated or ambient noise.

The tester’s analog tone mode is compatible with most tone probes.

The analog tone mode features the SmartTone™ function for positive identification of cables in bundles.

Toning in IntelliTone™ Mode (optional IntelliTone probe required)

Refer to Figures 1 and 2.

  • Connect the tester to the cable.
  • Press PORT to select twisted pair or coaxial cable.
  • Press MODE until MUSIC NOTES appear, IntelliTone, and a scrolling pattern of 1s and 0s appear on the display (1, 2, and 3 in Figure 1).
  • To toggle between the two IntelliTone songs press UP ARROW then DOWN ARROW. The display shows the song number 4.If you press DOWN ARROW or UP ARROW repeatedly, the tester cycles through the IntelliTone and analog songs.
  • Turn the probe’s rotary switch to Locate.
  • Use the probe to find the general location of the tone at a cable rack, patch panel, or behind a wall, as shown in Figure 2. The SYNC LED lights up green when the probe is receiving the IntelliTone signal.

    The probe’s LEDs light up from 1 to 8 as the signal strength increases. The higher the number, the stronger the signal.

    Notes: If you cannot locate the IntelliTone signal on 2-conductor cables, the cable may be shorted. Use the tester to check for shorts.
  • Turn the probe’s rotary switch to Isolate.
  • Use the probe to isolate the tone source in the cable bundle or at the patch panel. The SYNC LED lights up green when the probe is receiving the IntelliTone signal.
  • The probe’s LEDs light up from 1 to 8 as the signal strength increases. The higher the number, the stronger the signal.

Figure 2. Using the Toner in IntelliTone Mode

Analog Toner Mode (optional tone probe required)

Refer to Figure 3.

  • Connect the tester to the cable.
  • Press PORT to select twisted pair or coaxial cable.
  • Press MODE until MUSIC NOTES appear on the display 1; then press DOWN ARROW to enter analog toner mode. The display shows a scrolling sinewave in analog toner mode 2.
  • To change songs, press DOWN ARROW. The display shows the song number 3. The analog toner has four songs.
  • If you press DOWN ARROW or UP ARROW repeatedly, the tester cycles through the analog and IntelliTone songs.
  • Use the probe to search for the cable.

Figure 3. Analog Toner Mode Display

Using the SmartTone Function

Use the SmartTone™ function when you have trouble locating a cable. This function changes the toner’s song when you short a wire pair in the cable connected to the tester. SmartTone works with the IntelliTone probe and with analog probes.

Note: Use the SmartTone function only on dry pairs of wires that are unterminated at both ends. Do not use this function on powered wires.

  • Press PORT to select twisted pair or coaxial cabling.
  • Press MODE until MUSIC NOTES appears on the display.
  • Press DOWN ARROW to select the analog toner mode (IntelliTone disappears from the display).
  • At the far end of the cabling, place the probe near the ends of the cables.
  • Momentarily short a wire pair in a cable (twisted pair) or short the conductor and shield in a cable (coaxial). If the song changes when you release the short, you have found the cable connected to the tester.

Using the IntelliTone Cable Map Function (optional IP200 probe required)

The tester’s IntelliTone function works with an optional IP200 probe’s cable map function to verify wiring at the far end of the cabling. The probe’s cable map function identifies the most common wiring faults on twisted pair cabling: shorts, opens, and crossed pairs.

  • Press PORT to select twisted pair cabling.
  • Turn the probe’s rotary switch to CABLE MAP.
  • Connect the tester and probe to the cabling as shown in Figure 4.
  • Press MODE until MUSIC NOTES appears on the display. IntelliTone mode is indicated by IntelliTone and a scrolling pattern of 1s and 0s on the display. See Figure 4.
  • The probe’s LEDs light in sequence to indicate the cable’s wiring. See the probe’s documentation for details.

Note: Normally, the probe’s SYNC LED lights to indicate reception of the IntelliTone signal. You may change the LED’s function to indicate shield continuity. See the probe’s documentation for details
