Triangles Indicate Actions
Example of Scrolling Text
Main Menu
The display uses solid triangles to indicate what will happen if the user
presses any of the buttons. When there is more information than can fit on
the screen, the Sniffter places up and/or down triangles on the right side of
the screen indicating that scrolling in that direction will display more text.
Menus are similar to scrolling text, but have an additional right triangle in
the left column pointing to the selected menu option. Use the up and
down buttons to move the triangle through the menu options and scroll.
Use the right button to accept the selected menu option. Use the left
button to exit to the previous screen.
Quickly Testing An Ethernet Jack
Turn the Sniffter on. Press the right arrow twice to go to the Main Menu and then Auto-Test Internet.
Disconnect an Ethernet cable from the back of a PC and connect it to the Sniffter’s Ethernet port, or use
the blue Ethernet cable to connect the Sniffter to any Ethernet jack.
Once connected you’ll soon learn whether you have a working network connection and what the up and
download speeds are. Press the right arrow to continue, and then select any of the other network tests
for additional information on the connection.

Cable Testing
Note that the Sniffter is only testing cable
continuity
(whether a signal reaches the other end of the
cable). It cannot detect split pairs or cross-talk on a cable.
To begin a test, insert a cable into the Sniffter’s Test A and Test B jacks.
You can test in-wall wiring by plugging long cables (that have already
been tested) into each wall jack and connecting them to the Sniffter.
The following screen shots show examples for various cable types. The pin map provides a detailed pin-
out of the cable. The paired numbers (A above B) represent a connection. For example, in the Ethernet
Crossover shot, the first pair of numbers tell you that “pin 1 on Test A goes to pin 2 on Test B”.
Special Cable Type
“Straight Through” cable
“Flipped” Cable
Nothing connected to tester
Open Pins
Shorted Pins (pins 1 and 4 on A
go to multiple pins on B)
