To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.

• The LAN Scout™ Jr. 2 is designed for use on unenergized cabling systems. Connecting the LAN Scout™ Jr. 2 to live AC power may damage it and pose a safety hazard for the user.

• Improperly terminated RJ plugs have the potential to damage the jacks on the LAN Scout™ Jr. 2. Visually inspect an RJ plug before inserting it into the tester. Plugging 6-position plugs into the 8-position jack on the tester has the potential to damage the outer-most contacts of the jack unless the plug is specifically designed for that purpose.

1. Tone icon: Illuminates when the tester is transmitting Lo or Hi or LoHi tone frequency; additionally, the conductor wires being toned on will illuminate.

2. Pass icon: Illuminates if the cable is a properly wired 4-pair T568A/B data cable or crossover (uplink) cable.

3. X-Over: Illuminates when cable is correctly wired in the Crossover pattern.

4. Shielded: Illuminates when a data cable has a correctly assembled shield contact between the two terminated ends.

5. Voltage Detected Warning: If voltage is detected on the cable being tested, the “Voltage!” icon illuminates. A check for voltage is performed before each test and if found, no test is run. The tester should be disconnected immediately from the source of the voltage.

6. Fail icon: Illuminates if the cable is not wired to one of the cabling standards, and the appropriate fail mode icon(s) illuminates.

7. Short icon: Illuminates if there is a short on any two or more conductor wires, along with those pin numbers.

8. Split icon: Illuminates if the designated wire pairs are not terminated in the correct sequence.

9. Open icon: Illuminates when any of the conductor wires are not correctly terminated, along with that pin number.

10. Battery Low icon: Illuminates when the battery is nearing depletion. The symbol will begin to flash when the battery needs to be replaced. Results may be unreliable at this point.

11. Tester-End Wire Map: The top line of the wiremap displays the pins on the tester end in order. These pins are mapped to the pins on the remote-end shown directly below them on the LCD.

12. Remote-End Wire Map: The bottom line of the wiremap displays the corresponding pin on the remote-end. Dashed lines on the remote line indicate shorted pins. No pin numbers displayed on the remote line are open pairs.

Presses of less than about 1 second (short press) and more than 1 second (long press) are recognized differently:

1. Power/Backlight button:

• Short press: First short press turns unit on. A second short press turns backlight on. Any repeat of a short press turns the backlight on or off.

• Long press (greater than 2 seconds): Turns the unit off. “OFF” will display as the unit is powering down.

2. Cable testing (Test button):

• Short press: With the LAN Scout™ Jr. 2 on, a short press of the test button initiates a test. Loop mode (continuous test) is the default setting. A test occurs every 2 seconds with no need to press the test button.

• Long press: To turn off Loop Mode, long press the test button.

3. Toning (Tone button):

• Short press: Starting with the LAN Scout™ Jr. 2 on, a short press of the tone button will cause the unit to tone in the low (Lo) frequency mode on the first conductor wire. A second short press will transmit the Lo tone on the second conductor wire. Repeated short presses will cycle through toning on each individual conductor wire, then each mated pair, and then all 8-conductor wires. The mode and wires toned on will be displayed.

• Long press: A long press of the tone button will cycle the tone from the low frequency (Lo) to the high frequency (Hi) and to the warble cycle (Hi and Lo intermittently).

Auto Power Off: In test mode, the LAN Scout™ Jr. 2 will automatically power off 10 minutes after the last time the test button is pressed. In tone mode, the tester will turn off automatically 60 minutes after the last button press or by exiting to mode select with a long press.

1. Connect one end of the cable under test to the RJ45 shielded port located on the top of the main tester. If testing a wall port, connect a known good patch cable from the wall plate to the shielded RJ45 jack on the top of the main tester.

2. Connect the other end of the cable under test to the RJ45 shielded jack on the testing remote. If testing a wall port, connect a known good patch cable from the wall plate to the shielded RJ45 port on the testing remote. The remote can be removed or stored on the tester during testing.

3. Press the power button on the keypad to turn the tester on.

4. Press the test button on the keypad to begin the test.

5. Interpret the results of the testing using the wiring and display examples.

Properly Wired T568A UTP: The “Pass” icon will illuminate. The Tester-End Wire Map (top line) will show “12345678” and the Remote-End Wire Map (bottom line) will also show “12345678”, indicating all pins are correctly wired.

T568A Split Pairs: The “Fail” and “Split” icons will illuminate. This indicates the cable wiring does not maintain the designated pairs, which is an AC signal fault.

T568A Short and Open: The “Fail” and “Short” or “Open” icons will illuminate. An open fault or short fault takes precedence over miswires. For example, if the 1-2 pair pins are shorted and the 7-8 pair is open, the pins with the errors will flash. Dashed lines (-) on the bottom (remote) line indicate the short, while no numbers on the bottom line indicate an open pair.

T568A Miswire: The “Fail” icon will illuminate. A common error is when pairs are wired in the wrong sequence, for example, pins 1 and 2 on the tester end are connected to pins 2 and 1 at the remote end. The pins with this error will flash on the display.

1. Insert the RJ45 terminated end of the wire to be traced into the RJ45 shield port on the main tester body.

2. Press the power button on the keypad to turn the tester on.

3. Press the tone button on the keypad to begin toning. The tone will begin in the Lo mode on the conductor wire in position one on the connected RJ45 plug.

4. Short press the tone button to cycle through the conductor wires, 1 to 8, then mated pairs, then to all eight conductor wires simultaneously.

5. Long press the tone button to cycle through Lo, Hi, or warble (LoHi intermittently) tone frequencies.

6. Using an analog probe (Klein Tools VDV500-123 recommended, sold separately) to determine the wire or wires on which the tone is being transmitted. Mark the cable with a label.

7. Repeat steps above for each unknown cable.

1. Connect a known good patch cable from the wall plate to the shielded RJ45 jack on the top of the main tester.

2. Press the power button on the keypad to turn the tester on.

3. Press the tone button on the keypad to begin toning. The tone will begin in the Lo mode on the conductor wire in position one on the connected RJ45 plug.

4. Short press the tone button to cycle through the conductor wires, 1 to 8, then mated pairs, then to all eight conductor wires simultaneously.

5. Long press the tone button to cycle through Lo, Hi, or warble (LoHi intermittently) tone frequencies.

6. Use an analog probe (Klein Tools VDV500-123 recommended, sold separately) to determine the wire or wires on which the tone is being transmitted. Mark the cable with a label.

7. Repeat steps above for each unknown cable.

1. Remove the single screw in the middle of the back cover of the LAN Scout™ Jr. 2 with a #2 Phillips head screwdriver. Remove the battery door.

2. Remove and recycle the exhausted AAA batteries.

3. Insert two fresh AAA batteries following the proper orientation, as marked inside the battery compartment (the spring contact is negative and the button contact is positive).

4. Replace the battery door and screw, taking care not to over-tighten it.

Turn the instrument off and disconnect any cables. Clean the instrument by using a damp cloth. Do not use abrasive cleaners or solvents.

Remove the batteries when the instrument is not in use for a prolonged period of time. Do not expose it to high temperatures or humidity. After a period of storage in extreme conditions exceeding the limits mentioned in the Specifications section, allow the instrument to return to normal operating conditions before using it.
