Micro
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).
