The LAN Scout™ Jr. has a single button to both start a test and select other
functions and options. Presses of less than about 1 second (short press) and
more than 1 second (long press) are recognized differently.
1.
cable testing (short press): With the LAN Scout™ Jr. off, each short
press of the button causes a cable test to be executed and the results
displayed for 20 seconds before powering off. "TEST" is displayed
while testing is being performed. If another short press occurs before
the 20 second time out another test and 20 second time out begin.
If the button is pressed and held until "LOOP" is displayed and then
released, tests are run continuously and the display updated. The LAN
Scout™ Jr. will turn off automatically if there is no test result change
for 5 minutes. A long press of the button will cause the LAN Scout™
Jr. to exit cable test loop mode and enter mode selection as discussed
below.
2.
Mode Selection (long press): Starting with the LAN Scout™ Jr. off, a
long press of the button will cause the LAN Scout™ Jr. to enter mode
selection. In mode selection the LAN Scout™ Jr. cycles through cable
test and tone generator modes. The mode displayed when the button
is released will begin execution. From powered off, the modes in order
are:
• Loop: Cable test that loops continuously until it times out or
is exited by a long press that reenters mode selection. Used to
troubleshoot intermittent problems.
• four tone cadences (Hi Lo 1, Hi Lo 2, Hi, Lo): The next four modes
are all tone generator modes with different sounds. The "Hi Lo"
tones are made up of two frequencies with different timings. "Hi"
and "Lo" are single frequency. Once in a tone mode, short presses
change the pins carrying tone. The pins with tone are displayed. In
a tone mode, the Jr. will turn off automatically 30 minutes after the
last button press or by exiting to mode select with a long press.
• off: When the button is released with "OFF" displayed, the Jr. will
power off. Once in one of the above modes, OFF is the first mode
offered upon exiting to mode select. To select a different mode
other than OFF, continue to hold the button down and the next
mode in rotation will be displayed next.
• caBLE: The cable test mode is the single cable test mode with 20
second timeout that a short press from powered off executes.

T568B is electrically identical to
T568A, but swaps the green and
orange pairs. Either standard will
work as long as the same standard
is used at both ends of a run or patch
cable. Mixing "A" and "B" creates a
cross-over cable.
t 5 6 8 a c a b l e w i t h S p l i t pa i r s :
A common error in building a cable
is to put all the pairs in pin sequence
1-2, 3-4, 5-6 and 7-8. This will
produce the correct continuity, but
the pairs are designated to be on
pins 3-6 and 4-5 in the middle of
the connector for compatibility with
phone wiring. This wiring error is
only detected by the split pair test
since the designated pairs are not
twisted together.
