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).
