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. is designed for use on unenergized cabling
systems. Connecting the LAN Scout™ Jr. to live AC power may
damage it and pose a safety hazard for the user.
Poorly terminated RJ plugs have the potential to damage the jack on
the LAN Scout™ Jr. Visually inspect a RJ plug before inserting it into
the tester. The contacts should always be recessed into the plastic
housing of the plug. 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
“Pass” illuminates if the cable is a properly wired 4-pair
T568A/B data cable or cross-over (uplink) cable. A cross-over
cable will have the pin numbers of the crossed pairs flashing and
The “Miswire” icon illuminates if the cable is not
wired to one of the cabling standards. An open or short error takes
precedence over miswires and the appropriate icon(s) illuminates.
The “Split” icon illuminates if the designated pairs are not twisted
together in the cable, an AC signal fault.
The top line 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.
The bottom line displays the
corresponding pin on the remote-end. Dash lines on the remote
line indicate shorted pins. No pin numbers displayed on the remote
The battery low symbol illuminates when the
battery is nearing depletion. The symbol will begin to flash
when the battery needs to be replaced. Results may be unreliable
The “S” icon illuminates when a shielded data cable is
properly connected at both ends. It will be flashing if there is a
short to a wire in the cable along with that pin number and the
7. Voltage Detected Warning:
If voltage is detected on any of the
tester connectors, 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
