Important Safety Information

Read and understand this material before operating or servicing this

equipment. Failure to understand how to safely operate this tool could result in an accident causing serious injury or death.

Electric shock hazard: Do not connect this unit to AC power circuits. Failure to observe this warning could result in severe injury or death.

Important Safety Information

Electric shock hazard:

• Using this unit in a high frequency activated area may result in unstable or inaccurate readings.

• Do not drop or get the unit wet as it may cause internal damage.

• Do not attempt to repair this unit. It contains no user-serviceable parts.

• Do not expose the unit to extremes in temperature or humidity. Refer to “Speciﬁcations.”

• Use this unit for the manufacturer’s intended purpose only, as described in this manual. Any other use can impair the protection provided by the unit.

Failure to observe these precautions may result in injury and can damage the unit.

Electric shock hazard: This unit is capable of withstanding voltage input

conditions when connected to normal telephony equipment (i.e., 50 VDC) for short periods. Testing is inhibited when greater than a few volts is connected across a pair with the message shown here displayed on the screen. Disconnect the unit immediately to prevent permanent damage.

Failure to observe this precaution may result in injury and can damage the unit.

LCD Icons

6 7

The unit’s interface employs a high-contrast, backlit LCD panel to aid ease of use. The icons are used in the following way:

1. Tel, Coax, Ntwk: Telephone, Coaxial,

or Network test mode is selected.

2. Tone: Pair Tracing Tone is active.

3. Reversed: Polarity of telephone pair

is reversed.

4. Battery is low.*

5. Miswire: Wiring is not one-to-one.

6. Shield: Shield or screen is

connected.

7. Short: Some wires are short circuit.

8. Digits showing wiremapping to remote unit.

9. Open: Some wires are open circuit.

10. Pass: All wires are connected one-to-one (correct).

11. Split: Split pair is detected.

12. VOLTS!: Voltage is detected on one or more pairs; testing is inhibited. Disconnect quickly to prevent damage.

* The NETcat Micro requires one 9 V snap-type battery (alkaline types are recommended).

When the low battery icon is displayed, a few hours of typical use remain. Using the unit with a low battery will eventually affect the accuracy of measurements.

Operation

Switch ON, OFF, and Auto-Off

• To switch the NETcat Micro unit on, press the desired mode button for half a second.

• To switch the unit off, press a different mode button for half a second.

• To extend battery life, the unit will switch itself off after approximately 5 minutes without any button being pressed. The unit will not switch off in Tone mode.

Network Cable Test (Ntwk)

Network test mode allows the user to check typical RJ45 cables, such as CAT5 or similar speciﬁcation including shielded types, for correct wiring.

1. Connect the remote unit using a short patch lead (previously tested) at one end of the

cable to be checked and the NETcat Micro at the other end.

2. Press Ntwk. The unit immediately checks for the presence of voltages. If none are

found that may interfere with testing or damage the unit, tests are carried out to check the wiring of the pairs of the cable and, if present, the shield of the cable.

3. Check the icons on the display. If the cable is miswired so that wires of different

pairs are used where true pairs should be used, the “Split” icon will be set. Note that splits may only be detected in cables over 2 m (5 ft) in length. Note also that split pair detection may be switched off by pressing and holding Ntwk for 2 seconds if you wish to ignore split indications given for non-standard wiring systems. The default mode is “Split On”.

Telephone Cable Test (Tel)

As above, but for cables of up to three pairs wired to the RJ12 socket. One additional test is done in this mode where pairs with reversed polarity are identiﬁed and the “Reversed” icon will be set if this is the case. There is no shield continuity test in this mode.

Coaxial Cable Test (Coax)

As above, but for one pair (i.e., coaxial cables).

Test Details

Voltage Checks

This test checks for a voltage in excess of a few volts DC across each pair. If a voltage is detected above this threshold, then testing will be inhibited.

Wiremap

This test checks the cable for correct wiring when the remote unit is connected to the end of the cable under test. The cable conﬁguration is tested for shield continuity (if ﬁtted), opens, shorts, reversed pairs, crossed pairs, and split pairs. Below are examples of detectable faults along with a good wiremap.

Examples of Common Results

Simple RJ11 Telephone Cord

This screen shot shows how a simple RJ11 to RJ11 connection lead is tested. As the plugs are connected the “same way up” either end of the cable, there is effectively a polarity reversal. And as only a single pair is connected, the other pairs (2/5and1/6) are open.

CAT5 Crossover Cable

This screen shot shows how a typical two-pair crossover cable is often used to connect devices back to back, with the pairs 1/2 and 3/6 swapped. This is still shown as a “Miswire” as the only condition to allow the “Pass” icon to be set is a perfect straight through cable. As there are several different types of crossover cable currently in use, it was decided to show the condition and allow the user to decide if the result is what you require in your speciﬁc application.

NC-100 NETcat® Micro

Tracing Tone Mode

This function provides a means of tracking cables by generating one of three distinct selectable tones on a speciﬁc wire, pair, or all pairs. The cable can be traced using a tracing probe that is capable of detecting tones ranging from 577 Hz to 983 Hz.

The three available tones are as follows:

• HiLo1 – Fast Warble

• HiLo2 – Medium Warble

• HiLo3 – Slow Warble To select the relevant Tracing Tone mode, ﬁrst select the cable type by switching the unit

on in Network, Telephone, or Coaxial mode. Then press Tone to activate the tracing tones. Repeated quick presses of Tone will allow you to select which wires or pairs are carrying the tone depending upon mode. A long press of Tone (more than 2 seconds) will select the next type of tone, “HiLo1”, “HiLo2” or “HiLo3”.

This screen shows, for example, that all wires of a network cable are carrying the “HiLo1” tone.

In this screen only wire “3” of the telephone cable is carrying the “HiLo2” tone.
