OPERATION
To test a hub, switch, router or NIC, connect a patch cable from the RJ-45
port on the equipment, patch panel or wall outlet to the RJ-45 jack on the
LanMaster 35.
START SCREEN
Turn on the LanMaster 35 by pressing the “PWR” button. The unit displays
an information screen and then the START screen for selecting a test.
POWER TEST
Pressing the POWER function key begins a voltage scan of all wire pairs on
the RJ-45 connection. If no voltage(s) is found, a “No Power” message is
displayed and an EXIT function is provided to return to the START Screen.
When voltage(s) is detected the POWER display is presented. The power
configuration is shown as “End-Span” (pairs 1,2 and 3,6), “Mid-Span” (pairs 4,5
and 7,8) or “All-Span” (pairs 1,2 4,5 and 3,6
7,8). The type of power is displayed as “PoE
Standard” (complies with IEEE 802.3af), “Cisco”
(Cisco pre-standard power) or “Non Standard”.
The voltage and polarity of the powered wire
pairs are also displayed. NOTE: If power is detected on additional wire pairs, a
double headed arrow will appear next to “Pair”. Pressing the UP/DOWN cursor
key will scroll through the additional wire pairs. The voltage measurements are
continuously updated in the POWER screen.
Pressing the INFO function key presents the POWER INFO Screen and
starts a loaded power test. The “No Load” and “Load” voltages are displayed.
The load test for a PoE Standard Link is about
10 Watts and the load test for a Cisco Pre-
Standard Link is about 5 Watts. (The loaded
power test is not available for Non-Standard
power types or when less than 40 Volts is
measured for PoE Standard and Cisco Pre-Standard Links.) A voltage difference
of about 0.5 to 1.0 Volts is typical for short cables (1 to 25 feet) and 2.0 to 3.0
Volts is typical for long cables (200 to 300 feet). Larger voltage drops indicate a
problem in the cabling system or an under powered port. Link Resistance is
shown and is typically 0.5 Ohms for the port plus 2.0 to 2.5 Ohms per 100 feet of
cable. Higher resistance values indicate a problem with the cabling system.
Pressing the UP/DOWN cursor key will scroll through any additional wire pairs
that have voltage and display Link Resistance for each pair. Pressing the INFO
function key returns to the POWER Screen.

BATTERY LIFE
Duration - The LanMaster 35 will typically provide about 5 to 6 hours of
operation from a set of four AA alkaline batteries.
Auto Power Down - The Lanmaster 35 will automatically turn off after the time
selected in the Power Down Setup screen or will run continuously until manually
turned off when “ON” is selected for Power Down.
Low Battery - When the batteries are below the level required for the LanMaster
35 to operate properly, a battery graphic appears in the upper right hand corner of
the display.
SAFETY
Disconnect any connections to the LanMaster 35 RJ-45 before opening the
battery cover.
