Automatic Power Saving Features

The LANTESTPRO has built in power management features intended to extend battery life. By far, the LCD back light is the most power­hungry component in the LANTESTPRO. Use of the LCD back light should therefore be limited to low ambient light applications. The back
light may be toggled ON/OFF by simultaneously pressing the MODE/SEL and ESC function keys. If there is no further menu selection or
function testing within 30 seconds, the back light will be automatically extinguished. Additional power management functions include both a
“sleep” mode and an auto “power off” mode. If there is no key activity for 3 minutes, the unit will automatically enter “sleep” mode. All
interface circuitry and the LCD display will be powered down. In this mode the unit draws very little power. Presing any key will cause the
unit to “wake up” to a full functioning state. However, if there is no key activity for 10 minutes, the unit will automatically “power off”. To
recover from the “power off” mode, the unit must have its power switch cycled OFF and then ON. In the “power off” mode the power usage
remains low. This feature is especially useful if the unit is inadvertently left powered on. The battery should be replaced when the battery low
icon on the LCD display becomes visible during normal use of the LANTESTPRO. Additionally, if a low battery is swapped within 1 minute
with a new one, the user defined memory contents will be retained. Just remember to turn the unit OFF before swapping the battery.

Operation

1. Connection: The LANTESTPRO is capable of testing cables in any one of four modes.

1. Local Test mode
is accomplished by
connecting both
ends of the cable
being tested to the
LANTESTPRO’s
OUT and
LOOPBACK IN
ports. Local unit
displays an ID
equal to zero.

2. Remote Test mode
uses 2 LANTESTPRO
units, with the cable
connected between
on unit’s OUT and
the other unit’s
LOOPBACK IN
ports. Remote unit
displays an ID equal
to zero.

3. Terminator Loopback mode uses the
supplied terminator ID block connected
at the remote end of the cable, while the
other end of the cable is connected to the
LANTESTPRO’s OUT port.

4. 10BASE-2 Test uses the supplied RJ­45 to BNC. The adapters may both be
placed in the LANTESTPRO’s RJ-45
jacks for local test or on may be placed
at the LANTESTPRO’s OUT port while
the other is placed on the terminator
for Terminator Loopback testing.

seconds, then will display the top menu for “cable test”.

7. Use MODE/SEL to toggle between cable pin out screen and result display, press ESC back test menu.

Cable Testing

During any mode of cable testing, the first screen display will show the top line out and bottom line in of connections 1 through 8 plus G
(shield) as they are scanned. Following this screen page will be the cable indentification. If at least one wire pair is not connected, the display
will read “NO CONNECT”. A shorted cable will read “SHORT”. A question mark in the pin out display indicates a short. An unknown is not
the standard known pin outs or in the User Defined memory.

User Defined Cable

The User Define function allows you to describe your own custom cable pin out which will be entered into the cable indentification database
and saved in the CPU memory. This custom pin out will remain available as long as a fresh battery is in the unit. Two methods are available
for defining a cable. The first method is manual entry, while the second uses an “UNKNOWN” cable as the pin out source. First the manual
method. From the very top of the LANTESTPRO menu (just after power on is completed) select the USER DEF menu by pressing the
MODE/SEL button (step 1 to 2). The MODE/SEL button will now move the cursor to select one of four user memory locations (setp 3). Press
ENTER to select the memory location that the cursor is on. The define display will show (step 4).

ESC

To save your definition, press ENTER. To exit without saving, press ESC. The alternate method is to save the “Unknown” type.

Select the Location with MODE/SEL and then press ENTER to save. Press ESC at anytime to exit.

Cable Fault Identification Examples:

In the above example, Pin 1 and Pin 2 were found to be shorted.

In the second example, if a least one pair of the wires is not connected, the test result will show as “NO CONNECT”.
