Using the KE7200 / KE7100
Keypad
When the KE7200 / KE7100 was developed, emphasis was placed on
fast and easy operation. For this reason, the KE7200 / KE7100 has only
seven buttons despite its many test options.
ESC
Similar to a PC, the ESC button means “undo the last step.”
ON/OFF
Button for turning the device On and Off. This button has a delay of
approx. 1 sec. when turning off.
Four arrow buttons
The arrow buttons are for menu scrolling UP▲ /DOWN ▼and LEFT◄
/RIGHT►.
SEL button
The SELECT button. Press this button to select a function or start a test.
Similar to a PC Enter key.
Test settings
Wiring (Main menu>Setup>Wiring)
You can select from the list of different possible types of wiring (which pin
to which wire). This can even be changed during the cable test. It is
important to precisely specify the correct type of wiring because a
Pass/Fail result relies on it. The proper identification of errors in the case
of split pairs also requires a precise definition.
Sixteen popular versions are predefined. The following abbreviations are
used:
UTP = Unshielded Twisted Pair in a cable
STP = Shielded Twisted Pair in a cable
CR = cross connected cable
Velocity (Main menu>Setup>Velocity)
This is the propagation velocity (VP) of the signal in the cable expressed
as a fraction of the speed of light. This information is necessary to

measure length with the TDR function. The value must be correct if the
measurements are to be precise.
Obtain the VP data from the cable manufacturer. If there is no data on the
cable, the VP factor can be determined from a piece of cable with a
known length.
First perform the cable test on this piece of cable without a remote. After
the test is finished, go to the Velocity menu. The measured length for the
set VP is displayed here. Press the ▲ or ▼ buttons until the known cable
length is displayed. The displayed VP value is the one that will be used
for this cable. You can then create your own table definition in the Test
settings/cable definition menu.
Cable Type (Main menu>Setup>Cable type)
You can retrieve the cable definitions. Seven different cable types with
the VF factor are predefined.
Device settings (Main menu>Setup>Device
setups)
These are preset values and can be left unchanged. If needed there is a
selection to "Reset to defaults." The possible control selections for the
menu are shown on the bottom status line.

Program update
If new or improved functions or possibly bug fixes will be available, they
can be installed in conjunction with the KE7x00_FLASH.exe. Run the
program, connect the tester via Ethernet cable to the PC and start the
update process under Settings / DeviceSettings / Program update. For
the update, all data must be deleted, run this by simultaneously pressing
the <and >keys, then enter the in the FLASH program displayed IP
address. Herewith the update process is finished and the tester is
equipped after a restart with the new firmware.
Test settings (Main Menu>Setup>Test
Setups)
Cable definition
You can select from the list of the different cables in use. The cable type
is assigned to the name and associated VP value. The VP value is
needed for measuring length. The cable type only appears in the saved
or printed results. Enter the cable that is being used.
You can create your own definitions. See Appendix A.
Wiring definitions
Approximately 16 different wiring versions are predefined for your
selection. You need to correctly choose the wiring version to be tested to
obtain Pass/Fail information. This information must be correct (pin to pair
assignment) to test for crosstalk.

With the KE7200 / KE7100, the wire to pin assignment is checked and
the correct pair assignment is also checked. This is done with a high
frequency test signal to provide true results.
You can also create your own versions in this menu. See Appendix A.
Remote ID
KE7010 remote test units are all delivered with a number “32” identity for
simplicity.
With the Remote ID function from the Test Setup Menu you can set any
KE7010 remote to any ID number from 1 to 32. After changing the
number, write down the new number with a pencil in the label space on
the remote.
MAC address - KE7200 only
The KE7200 comes with a MAC address set. All of the testers have the
same address when delivered. To work in networks with MAC address
verification, the address can be set to any value in this menu
IP address (Main menu>Setup>IP address)
The IP address of the KE7200 is preset but can be changed. This
address is used as the device address even during the IP test, for
example as a static network address.. Simply set the address with the ▲
and ▼ / ◄ and ► buttons and save with SEL. The change can also be
made directly during the IP test in the same manner.
Testing with the KE7200 / KE7100
The KE7200 / KE7100 checks the connected line for external voltage
each time before starting one of the four possible tests. If external voltage
is present, the test is not started and the level of the voltage is displayed
in volts. The test may only be run after the external voltage has been
turned off.
External voltage does not have anything to do with PoE during this type
of detection. With PoE systems working properly, the voltage supply
always needs to be activated.
Cable test (Main menu)
The cable test can be run with or without the KE7010 remote unit. If it is
run without the 7010 remote, only cable length is measured and a split
pair check is done.

When the remote unit is connected to the end, measuring the length
using the TDR method is accurate enough to determine if a cable is
within the 90 meter maximum length standard. This test can measure a
maximum of 150 m.
We recommend measuring the length of installed cables separately
without the remote. This measurement of length is more precise since a
specific end is detectable without the remote.
Performing the test
Using the supplied patch cables, connect up to 32 remote units to the
ports to be measured. If only one remote is being used, the remote needs
to be brought to the next connection point after the test. When using a
helper, the helper can determine whether the test yielded any errors by
the flashing rhythm of the LED. If no errors are found, the LED flashes
slowly once every second and the remote can be brought to the next port.
We generally recommend using several remotes, one for each room.
With 32 possible unique remote IDs somewhat larger facilities or a
section of a facility can be easily covered.
The main advantage is that it saves time since only one person is
required. The unique remote ID numbers show up in the saved records,
too.
With the 0.5 m patch cable, connect the KE7200 / KE7100 (supplied) to
the port to be tested in the patch panel or wall jack.
On the Main menu select "Cable test," start the test by pressing the SEL
button. The message "Cable test running" indicates that the test is
underway and the progress is displayed as a percentage. If the test is
without errors, a long beep sounds and the okay checkmark is shown in
the display. The LED in the remote flashes once every second signifying
a Passed test.
If an error is found, two short beeps sound, the LED in the remote flashes
quickly 4 times (0.5 seconds in length), then pauses for one second, and
then flashes again quickly 4 times, etc.
The number of the remote unit is always displayed in the KE7200 /
KE7100 at the top left of the display. This is followed by the type of cable
wiring selected. This can be changed by pressing the ▼ button. Then the
set VF value is displayed. It is either selected by choosing a cable type,
or by setting it directly beforehand.
The wire mapping is displayed in the main window. This clearly identifies
any circuitry errors. Split pairs are displayed with a branch to the linked
wire which then returns. The measured distance to the panel appears in
right field. Distances of less than 2 m are not shown. The measurement is
too imprecise at this close range.

The maximum length that can be measured is approximately 150 m.
However, this depends on the cable itself.
The bottom display line is the dialogue line. The possible operating steps
for the current test are displayed in this line.
Navigate with the ◄ / ► buttons to see the identified details per wire.
This allows for example an open or short to be clearly assigned to the
near or far end. If the fault is somewhere in between, then its location is
indicated in meters.
The ◄ button reveals the length of the wires and the ► button indicates
the number of errors, type of errors, the affected pin, where it should be
and where it actually is, if misconnected, as well as the distance to the
fault. In the case of split pairs, of course only the linked pair can be
defined. Sometime individual couplings between other wires can be
identified. Because of the split pair, the crosstalk also relates to other
neighboring wire pairs. Make sure that the selected wiring version
(such as 568A) corresponds to the actual cabling.
Save the data - KE7200 only
After the measurement has been taken, you can either exit measuring by
pressing ESC, or you can save the measurement. Press the SEL button
to open the Save the data menu. The default name of the measurement
is displayed, followed by a number. A unique name must be provided if
you want to associate the data at a later time. We recommend the
customer name or number. Enter the name by pressing the▲ or ▼
button. This allows you to scroll through the alphabet and numbers 0-9.
Press SEL to enter the desired character. Change the cursor position by
pressing ◄ and ►.
The name remains entered until it is overwritten. That is, if the customer
remains the same, you do not have to change anything when saving the
next measurement. The number of the measurement is automatically
incremented. Afterward, you can sort, print out and save based on the
customer number or name. Remember that this setting may need to be
changed before starting a series of measurements at a different facility.
The available memory is displayed in the second line. A total of
approximately 14,000 entries is possible.
Cable/wire trace
The KE7200 / KE7100 has two different ways of identifying a known jack
on the patch panel, switch or hub. Insert the test cable of the KE7200 /
KE7100 into the outlet box in the room and select Test Link/Blink in the
Cable/wire trace menu. This only tests if the box is active in the network.

Operating Manual
KE7200 / KE7100

KURTH ELECTRONIC FERNMELDETECHNIK
www.kurthelectronic.de [email protected]
The response is displayed in the status line. If there is an active
connection, the message appears: "Ethernet 10/100/1000 Mbit
connection“
and only the identified speed is displayed.
If the port is not active, "No connection" is displayed. Then you can switch
to one of the 4 tone transmission modes. The trace tone is transmitted on
all of the wire pairs. The assigned port in the patch panel can be clearly
identified with the PROBE.
PoE/PoE+ test per IEEE 802.3af/at
Start the test by pressing the SEL button. The KE7200 / KE7100
activates the PoE port and shows in the display whether the PoE is
available or not. If the PoE can be activated, it is. Then the maximum load
is applied to drain the cable charge. The maximum available power is
then measured. This is done according to IEEE 802.3af and to IEEE
802.3at. The standard regulates the voltage that can be on the line when
a specific current is flowing. If the voltage is below the standard value, the
KE7200 / KE7100 reduces the load until the voltage lies within the
normal range. This power is then calculated and displayed. Start the test
new for each measurement.
This information is important in every network with PoE powered devices
since faults repeatedly arise because the power supply in the switch has
reached the limit. If a small, additional load is created, for example from
different operating conditions such as turning on an infrared light, the
network fails and the switch only provides the emergency power. This
situation cannot be detected without the proper test equipment.
IP test –KE7200 only
In the IP test, the KE7200 can search the network for IP addresses and
users. This can be done in DHCP mode or with a fixed IP. If the network
is also monitoring MAC addresses, the MAC address of the KE7200 can
be changed.
First, DHCP mode is started by selecting "IP test/DHCP request". A
connection to the network is established. Once this is available, it is
shown in the status line. The IP address allocated to the KE7200
via DHCP is displayed. The search for allocated IP addresses starts
immediately in the assigned address space. The number found is also
displayed. The KE7200 then queries all of the addresses for information
which it lists. If names are available, they are displayed; if not, only the IP
address is displayed.
This procedure can take a while, especially if there are many users in the
network. You can monitor the changing of the found IP addresses.

Press SEL to save these data.
Press ESC to open the user list. When a user is selected, the IP and
MAC address are displayed in addition to the name. This address can
then be pinged in this menu.
Select SEL to open the PING menu. The range is displayed in the top left
corner. This can be changed from 32 to 124 bytes with the ▲ / ▼
buttons.
Start pinging by pressing SEL.
The KE7200 continuously transmits pings to the selected address. This is
done at the maximum speed so that a stress test is simultaneously
performed for all components.
The success of the test is displayed by the number of sent pings and the
number of lost pings. Then the maximum, minimum and average
response times are displayed.
Transmit measurements - KE7200 only
The saved measurements can be sent to the KE Manager for further use.
Start the Manager on the PC.
Connect the KE7200 to the PC using an Ethernet cable. In the main
menu, select "Transmit measurements."
The saved data are transmitted immediately after synchronization and
appear in the Manager window. The KE7200 can now be disconnected
from the network.
If there are no saved measurements, this is reported.
The data on the KE7200 can be deleted. If they should not be deleted,
press ESC.
