communications, so the TVR1000 can be used to continuously
monitor the link for data and link activity plus speed and duplex.
These jacks and associated LEDs are the heart of the Main Unit’s
ability to save you time with your LAN tasks.
GREEN JACK (Single port and Inline tests): The most used jack
of the three is the “Green jack” (named by its green border). All
three jacks will verify the device type (hub/switch, PC); the presence
of Data; Link pulses; Speed/Duplex; and PoE, but the Green jack
is used most often because it is a “straight thru” connection to the
tester’s circuitry making it the best choice for "single port" tests. The
LEDs labeling is anticpating that devices connected to the Green
Jack will use a straight thru cable.
MIDDLE JACK (Inline tests): The middle jack is also connected
straight thru to the tester. Using the Middle Jack and the Green
jack inline between two devices creates a straight thru connection.
RIGHT SIDE JACK (Inline tests): The jack to the far right is con-
nected to the tester by a crossover connection. Using the Right
Side Jack and the Green jack inline between two devices creates a
crossover connection between the two devices.
All three jacks 1) provide input to the Data, Link, Speed, Duplex
and PoE sensing LEDs and 2) simulate both straight thru (=) and
crossover (X) connections(allowing you to determine which style
patch cable is required to connect the two LAN devices).
When performing inline tests, first power ON the tester, then allow 3
seconds between plugging in devices (the time it takes the TVR1000
to make a reading).
