PRODUCT FEATURES
Description
The Wire Mapper Pro is a hand-held structured cable tester and troubleshooter designed for use on UTP, STP, FTP & SSTP cabling equipped with RJ45 connectors and wired to either TIA 568A/B (ISO11801 & EN50137), USOC or ISDN specifications. It detects open circuit pairs, shorts, crossed wires, crossed pairs, reversed pairs, shield faults and split pairs. In the event of opens and shorts, the Wire Mapper Pro uses TDR technology to indicate if the fault is at the near end of the cable, the remote end, or if it is somewhere in between. It will then indicate the distance to the fault. The Wire Mapper Pro has the ability to measure and indicate the length of thecable under test, using a Vp (Velocity of Propagation), set by the user. It will measure and report the length of all 4 pairs of wires in the cable under test. It also generates an audible tone that is transmitted into all 4 pairs on the cable under test. This can be used for cable tracing and identification. This instrument also has the ability to identify telephone and data lines. If themain unit is plugged into an operational RJ45 socket, it will give a continuous warning tone and appropriate display if a telephone voltage is present on any of the pins. If the Service Detect key is pressed, it will give a display distinguishing 10base-T, Token Ring and 100Mbit+ connections.

OPERATION
Getting Started
The instrument is switched on and off using the green power button found on the lower right side of the front panel.
When the unit is first switched on, it will display the opening screen giving the software version and remaining battery capacity. The wire type (TIA568, STP…) and the Vp (Velocity of Propogation) is also displayed. To change these settings, see § 4.2 below.
Cable/Network Type and General Setup
To enter a menu for Cable and Network selection:
- Press down on the button, then press the MAP/ button.
Typical display:
The > (line selector) is moved by pressing the MAP / button. When the appropriate line is selected, the SERVICE / Vp and LENGTH / Vp buttons may be pressed to increment or decrement through the alternative options for the selected item.
- Under Type, the following selections can be made: TIA568 STP TIA568 UTP ISDN USOC UTP USOC STP
NOTE: For testing of wire map in accordance with ISO11801 & EN50137 the product should be set to TIA568 which is the equivalent standard. For FTP and SSTP cables use the STP setting.
- VP is selectable in the range 20% to 100%. (see § 4.3 if the Vp is not known)
- The Wire Mapper Pro may be set to measure cable length in feet or meters.
- The instrument may be set to operate in English (USA or UK), French, German, Italian, Spanish or Portuguese.
- The display contrast may be set by selecting Contrast and then pressing the SERVICE / Vp button to decrease the contrast or the LENGTH / Vp button to increase the contrast and optimize the display to the ambient lighting conditions. The unit also has a display backlight.
- To exit set-up mode, press the button.
Determining and Measuring Vp Values
Vp, or Velocity of Propagation, values are characteristic of each cable type and brand. The Vp is used to measure the length of a cable and to measure a fault location. The more accurate the Vp, the more accurate the measurement result will be. The cable manufacturer may list the Vp on their specification sheet or may be able to provide it when asked. Sometimes this value is not readily available, or the user may wish to determine it specifically to compensate for cable batch variations, or for special cable applications. This is quite easy:
- Take a cable sample of exact length increments (ft or m) longer than 60ft (20m).
- Measure the exact length of the cable using a tape measure.
- Connect one end of the cable to the Wire Mapper Pro (see § 4.11). Leave the end un-terminated and make sure the wires do not short to each other.
- Measure the length and adjust the Vp until the exact length is displayed.
- When the exact length is displayed, Vp is established.
TNV (Telecom Network Voltage) Testing and Warning
The Wire Mapper Pro is designed to work on nonenergized circuits only. Make sure that the circuit to be tested is not live before mapping.
Turn the unit on and plug it into the port to be tested with a short patch cord.
If a Telecom Network Voltage is present, the unit will give a continuous audible warning, and display the following:
NOTE: The pin on the RJ45 connection, on which the voltage is detected, is displayed.
In the event of a TNV (Telecom Network Voltage) Warning, the unit should immediately be disconnected and testing stopped, since it is not designed for testing on live networks.
Service Detection
To detect an active data port, plug the unit into the port to be tested using
a short patch cable and press the SERVICE / Vp button. The display will show
the type of data connection or service present from the following list:
General Operation
- Set the instrument to the desired cable type and wiring scheme (see § 4.2).
- Make sure no Telecom Network Voltages or other services are detected (see § 4.4).
- Attach the instrument to one end of the cable to be tested
- Attach the remote unit to the other end of the same cable
- Press the MAP / button.
The display will briefly show the following message while testing is being performed:
This screen is quickly followed by the test results screen.
- Test Pass/OK Screen
- Test Failed Screen
Test Pass/OK Screen
- The left side of the display shows information about the test performed and the status of the test result.
- The first line shows the unique identity of the active remote unit connected to the far end (in this case, ID1). There are 15 additional active remote units available as optional accessories (ID#2 to ID#16).
- The test status, PASS is indicated on the second line. A test PASS is confirmed by a double beep from the main unit and a double green flash on the LED of the active remote unit.
- Next, information about the test type selected, along with a measured value of the cable length, and an indication of the current VP setting is displayed.
- If a fault is found an appropriate message will be displayed, along with a warning tone on the main unit, and a red flashing LED on the remote unit.
Test Failed Screen
Open and Short Fault
In the event of an Open fault, the following is displayed:
Notice the word FAILED under the cable ID1 and also the detailed message at the bottom of the display. The graphical portion of the display also shows that the fault is an open on pin 7 at the remote end by showing a break in the line at this point
NOTE: In the event that an open or short circuit fault occurs at either end of a cable or link under test, the unit will show the fault as at the near end or the remote end. These faults are the most common and are mainly due to termination problems. If the fault occurs some way along the cable or link under test, then a display similar to the one shown below will occur. Notice, that on this occasion the actual measured distance to the fault is given.
In the event of a Short fault, the following is displayed
In this situation, the graphical portion of the display also shows that the fault is a short between pins 1 and 2 and the short is drawn at an approximation to the distance along the cable or link under test, at which it occurs.
Reversed and Split Pair Fault
In the event of a Reversed Pair fault, the following is displayed:
In the event of a Split Pair fault, the following is displayed:
NOTE: For cables less than 6 ft (2m) in length the tester is unable to distinguish a Split Pair condition. In this event (cable too short), the following screen is displayed briefly, before the screen to warn the user that a Split Pair test has not been carried out.
Multiple Faults
In the event of a multiple fault, or a cable or link with more than one fault on it, the tester will report the faults in the following order of priority.
- Shorts
- Reversals
- Opens
For example, on a cable with an Open on pin 3 and a Short between pins 7 and 8, only the Short in pins 7 and 8 will be reported. 4.10 Missing Remote If a wire map test is performed without a remote unit connected at the far end, the following screen will be displayed:
Cable Length Measurement
The remote unit does not need to be attached for this test to be performed. Although it does not matter if it is attached, any terminators on ISDN wiring or sockets should be switched out of the circuit or disconnected.
Attach the main unit to one end of the cable and press the LENGTH / Vp button. The length of all four pairs in the cable are measured, and the results displayed simultaneously, as shown below
In this example, the length of pair 3 – 6 is missing, as there is a fault on the pair which is preventing the TDR circuit from measuring the length. Length will be displayed in the selected units, either meters or feet, and the Vp and cable testing standard will also be displayed. Length measurement accuracy depends on the correct setting of the Vp (Velocity of Propagation) for the cable under test. If the Vp is not known for a particular cable, then a known length of that cable (at least 60ft or 20m long) may be connected to the instrument and the Vp adjusted until the correct length reading is obtained (see § 4.3).
Tone Generator
The Wire Mapper Pro may also be used as a tone generator, to trace and
identify cables and wires. The user will need a cable tone tracer, such as the
AEMC Tone Receiver/Cable Tracer Model TR03 (Cat. #2127.76).
Pressing the key will inject a warbling (oscillating) tone into the cable or link under test. When set, the following will be displayed:
The injected signal oscillates between 810Hz and 1110Hz, six times per second.
NOTE: The auto-off function is disabled in Tone Generator mode, so that the
tone can be injected into a cable for an extended period of time while tracing
takes place.
Backlight
The display backlight is switched on and off with the button.
