Application
Please read this important information!
Intended/Proper Use
The KE7200 is a network and LAN cable tester.
It is used for initial startup tests, for checking data and telecommunications networks, and for
troubleshooting. The results can be stored in the instrument or transferred to a PC. In the asso-
ciated PC software, the results can be documented and logs created.
The instrument is used in data and telecommunications networks (Ethernet/RJ-45 cables, coax-
ial cables/lines, telecommunications cables/lines) without external voltage. It is hooked up using
its RJ-45 socket and the supplied or optionally available accessories (see data sheet).
The KE7200 can be used to perform the following tests/measurements:
• Cable tests with error display:
Detection of reversed connections, short circuits, interruptions, overdrafts (split pairs; as of
2 m), testing of the data line assignment with pin and pair assignment (wire mapping), ca-
ble length measurement, and determination of the distance to the error with TDR function
• Network tests (Ethernet cable only):
IP test with listing of active network subscribers with name, IP address, and MAC address;
detection of network speed 10/100/1000 Mbit; ping test, including stress tests
• Power over Ethernet test (Ethernet cable only):
PoE/PoE++ test according to IEEE802.3af/at/bt
• Port nder function (Ethernet cable only):
Link blink function for identifying ports on routers/switches/hubs
• Search tone mode (Ethernet cable only):
Transmission of a search tone signal and identication of the associated network port via
tone detection with the P310*/P410** probe search signal receiver
• [With software option only] Branch detection
(coaxial cables/lines, telecommunications cables/lines only):
For precise localization (existence and distance) of branches/stub lines (bridge taps) in
telecommunications networks in buildings.
The external voltage protection of the KE7200 against accidentally applied external voltage is 60
V DC. The instrument emits a warning and displays whenever external voltage is present, and
tests can only be conducted after the external voltage has been eliminated.
Some measurements/tests require the KE7010 remote unit or the P310/P410 probe search sig-
nal receiver. For this reason, di󰀨erent instrument combinations are o󰀨ered (see scope of delivery
and data sheet).
The safety of the user and the instrument is only guaranteed during proper use.
* P310 included in the KE7200 PRO kit; optionally available for purchase separately
** P410 included in KE7207 and KE7208; optional available for purchase separately

The instrument must not be disposed of in the household trash; see page 27.
P310 Probe
The P310 probe is a non-contact test loudspeaker that receives the search tone signal
transmitted by the KE7200 and makes it audible.
A ashlight function with a pure white light guarantees clear color identication of the wire
markings in dark server cabinets. The ashlight turns on automatically when the instru-
ment is on and turns o󰀨 automatically when the instrument switches o󰀨.
The probe’s test tip is made of ber-reinforced plastic with a bayonet catch for easy re-
placement on site. See data sheet for test tip replacement.
At the lower end of the probe, there is a socket connector for an earphone (3.5 mm jack
plug) to allow signals to be heard more readily.
The probe is switched on and used by holding down the HIGH or LOW keys. The HIGH
position is the most sensitive level for locating weak signals. The LOW position is for
specifying which network port has been found, for example.
The P310 cannot detect the search signal in shielded cables! You will therefore nd the
search signal on the associated network port.
The P310 is also part of the EasyTest system for locating cables and wires. More information is
included in the EasyTest product documentation.

The update process will then start. After
approx. 1 minute, the update process will nish and the KE7200 will switch o󰀨.

13
Test/Measurement Settings
In order to perform all tests/measurements correctly, you need to make basic test settings.
In the Settings menu, you can select the Wiring Type for the test/measurement, select the
Speed (VF factor) for the TDR function, dene the Cable Type, and specify the IP Address of
the KE7200.
The Settings > Test Settings submenu provides additional specic test settings, giving you the
possibility of creating own cable and wiring denitions, managing the KE7010 remote units, and
specifying the MAC address of the KE7200.
Settings > Wiring
Here you can select the desired wiring type from the list of various options (which
PIN for which wire). This can still be changed during the cable test, however. The
specication of the correct wiring type is important, as all information on the wire
pair and PIN assignment is based on this. Without this information, it will not be
possible for an OK statement to be issued by the test. In addition, only the correct wiring deni-
tion will allow a split pair error message to be sent.
15 common variants are predened.
The following abbreviations are used:
UTP= Unshielded Twisted Pair
STP = Unshielded Twisted Pair
CR = Cross Connect
Settings > Speed
Here the propagation speed of the signal in the cable, the VF factor, is entered as a percentage
of the speed of light. This information is required for length measurements with the TDR function.
Only with the correct VF factor will the cable lengths be determined
correctly!
The VF factor predened for the selected cable type is displayed by default (for cable selection,
see page 14; for cable denitions, see page 14). The value can also be set manually via
the ▲ or ▼ keys.
The data can be obtained from the cable manufacturer. If no information is available on the cable,
the VF factor can also be determined with a piece of cable of known length.
Determining the VF Value
First conduct the cable test on a piece of cable without the remote unit. After completion this,
go to the Speed menu. Here, the measured length will be displayed for the set VF. Now adjust
using the ▲ or ▼ keys until the known cable length is displayed. The VF value to be read is the
propagation speed of this cable.
You can use it to create your own cable denition in the Test Settings > Cable Denition menu.

14
Settings > Cable
Various frequently used cable types are predened here (for a list, see page 14). The cable to
be tested/measured is selected from the list of di󰀨erent cables.
The name and the corresponding VF value are assigned to the respective cable type (see page
14). The cable type name appears in the stored or printed result. In contrast, the VF value is
needed for the TDR function.
You can also add to and change the predened cable types (see page 14).
Settings > Test Settings
> Cable Denition
The cable denitions are created here with a name and VF value, which can be selected for the
cables to be tested/measured (see page 14).
Predened cable types and associated VF values:
BELD DATATWIST 72% BELD 3600 PB29 72% UC300 HS24 S/F 67% LEONI E5-70 S/ 80%

Additional cable types can be created as well. Proles that have already been created can also
be overwritten.
After selecting the cable type to be edited, or alternatively an item without an entry, select it with
SEL. Name:| is displayed. A unique cable name can be entered here. There are 15 available
character slots. At the ashing cursor position, the ▲ and ▼ keys can now be used to scroll
through the alphabet, all digits 0–9 and an empty position. The digit or letter to be positioned at
the cursor position is selected with SEL. Once the name has been entered, conrm with SEL.
Speed: xx% will appear. This is the propagation speed in the cable, the VF value, as a percent-
age of the speed of light. Enter either the value specied by the cable manufacturer, the previ-
ously determined value, or an approximate value.
Tip: Phone and Cat3 cables have a value of approx. 64-68, Cat5/6 cables approx. 72, and Cat6/7
approx. 77.
After entering the VF value, save with SEL. This allows you to quickly and easily predene the
cable types you use.
> Wiring Denition
Correctly selecting the wiring version to be tested is essential for obtaining good/bad informa-
tion. Only if this pin to pair assignment matches can crosstalk be checked reliably. With the
KE7200, not only a wire-to-pin assignment is checked but also whether the pair assignment is
correct. This is done at a high frequency in order to obtain relevant information.
There are 15 di󰀨erent predened wiring options to help you make the selection. The abbrevia-
tions UTP, STP, and CR contained therein are described on page 13. After selecting the Wir-
ing Denition menu item, the Created Wiring Denitions list will appear:

Creating/Changing Wiring Denitions
Here, too, you can create your own versions, although you can only do so by changing an ex-
isting denition.. It is useful to note the pin/pair assignment of the wiring version being created
in advance.
After selecting a wiring denition to be changed, you will be taken to the Name menu. A unique
wiring name, such as “568C,” can be entered here. There are 15 available character slots. At the
ashing cursor position, the ▲ and ▼ keys can now be used to scroll through the alphabet, all
digits 0–9 and an empty position. The desired digit or letter at the cursor position can be selected
with SEL.
Once the name has been entered, conrm with SEL. The Connections menu will open, where
the PIN is assigned to the PIN and wire pair as corresponds to the wiring version. This assign-
ment is necessary both for recognition of the correct assignment in the tested cable and of split
pairs with regard to crosstalk and for good/bad information after a successful test. The scroll bar
is set to Pin 1.
Select with SEL, which will bring you to the Connection menu for Pin 1. Now the possible se-
lections of all 8 pins that can be assigned to Pin 1 will appear. Use the ▲ and ▼ keys to select
the correct pin with SEL. The next step is the Pair menu, where you can assign the selected pins
to a pair with SEL.
You will now be back in the Connections menu, where you can see the assignment of the Pin
1. Use the ▼ key to move the scroll bar to the next item, and continue with the assignment as
before.
If you create any incorrect assignments, you can only overwrite them. Alternatively, you can
select the Device Settings > Reset to Factory Settings menu item. This will reset all changed
wiring denitions.
> Remote Unit ID
The KE7010 remote units required for correct and quick cabling verication are included with
No. 32 to simplify inventory management. Under Main Menu > Settings > Test Settings > Re-
mote Unit, a connected remote unit can simply be reprogrammed to the desired number. After
changing the number, we recommend writing the new number in the space provided on the back
of the device.

17
> MAC Address
The KE7200 is shipped with a predened MAC address. In order to work in networks with MAC
address verication, the address can be freely dened here.
Settings > IP Address
The IP address of the KE7200 is set here. This address is always used as device address, in-
cluding for an IP test, such as as static network address. It can be changed at any time. Simply
use the ▲ and ▼ / ◄ and ► keys to set the address and save it with SEL. However, the change
can also be made directly in the same way, such as during an IP test.
Application
You can perform various tests with the devices.
• Cable test page 17
• Cable/wire search via the port nder function (link blink function) or search tone (tone mode)
page 19
• PoE/PoE++ test (according to IEEE802.3af/at/bt) page 19
• IP-Test (including network speed) and ping test page 20
• Detection of branches / stub lines (bridge taps) page 21
The KE7200 checks the connected line for external voltage before each start of the test options.
If present, the test will not be started, and the voltage level will be displayed.
External voltage present:
• The actual external voltage may be much higher than displayed!
The level of the external voltage is only displayed with an exact value
up to 74.7 V. All external voltages > 74.7 V are displayed as 74.7 V.
• Stop the test immediately if external voltage is present and discon-
nect all test leads!
A safety-critical condition may exist, and/or the unit may be damaged.
Fix the faulty network condition before continuing the test.
The test can only be performed after the external voltage has been switched o󰀨. External voltage
has nothing to do with PoE for this detection. For PoE systems that are working correctly, the
supply of voltage must always be activated.
Cable Test
The cable test can be performed with or without the KE7010 remote unit. If it is done without
the KE7010, only eld length measurement and checking for crosstalk due to split pairs will be
performed.
When the KE7010 is connected at the end, the length measurement using the TDR method is
su󰀩ciently accurate to determine whether the eld is in the 90 m range. This test measures up
to a maximum of 200 m. For measuring installed cables, we recommend performing the length
measurement separately without the KE7010. This measurement is more accurate with regard
to the length, since a clear end can be detected without the KE7010.
The cable lengths can only be determined correctly using the correct VF
factor! See page 13 f.

18
Test Execution
Up to 32 KE7010 remote units can be connected simultaneously to the ports to be mea-
sured using the included patch cables. If only one KE7010 is used, it must be taken to
the next port after the test has been completed. If an assistant is involved, he can de-
tect whether the test resulted in any errors by the ashing rhythm of the LED after the
test has been completed. If no error has been detected (slow ashing every 1 second),
he can proceed to the next port.
However, we recommend the use of several KE7010 units, one for each room. With the 32 pos-
sible KE7010 units, a patch eld area with, say, up to 32 ports can be easily covered, even with
somewhat larger systems. The main advantage is clearly time savings, as only one person is
needed. At the same time, there is a clear assignment of the measurements with the KE7010 in
the documentation.
Connect the KE7200 with the 0.5 m patch cable (included) to the port to be tested on the patch
panel.
Start the test with the scroll bar for Cable Test by pressing the SEL button. The progress infor-
mation is displayed with the Cable Test Running, and the progress is displayed in %. If the test
was free of errors, a long beep will sound, and the OK checkmark will be displayed. The LED on
the remote will ash steadily every 1 second.
If any errors are detected, two short beeps will sound, and the LED on the KE7010 will ash: 4×
briey (0.5 seconds), then a pause of 1 second, then again 4× briey and so on.
The KE7200 always shows the number of the KE7010 remote unit in the upper left corner of the
display, followed by the type of wiring. This can be changed by pressing the ▼ key, after which
the set VF value is displayed. This is set either by selecting a cable type or by setting it directly
beforehand.
The main window displays the Wire Mapping. Here, any existing wiring errors can be readily
identied. A split pair is displayed with a branching to the
connected wire and back again, with the measured eld
length appearing in the right eld. Lengths below 2 m are
not displayed. The measurement is too inaccurate in this
close range. The maximum length measurement is ap-
prox. 200 m, but this will also depend on the cable itself.
The lower display line is the dialog line. Possible operat-
ing steps for the respective test are displayed here.
Use the ◄ and ► keys to display the calculated details for
each wire. For example, an interruption or a short circuit
can be clearly assigned to the near or far end. If the error
is somewhere in between, the value can be read in meters.
The ◄ key shows the wire lengths, the ► key the number
of errors, the type of error, the a󰀨ected pin, where it should
be if incorrectly connected and where it is now, and the
length of the error.
By its nature, only the linked pair can be dened for split
pairs. In some cases, individual interconnections between
other wires are also detected. This is due to the fact that
crosstalk also a󰀨ects other neighboring wire pairs due to
the split pair.
As a rule, it is also necessary to ensure that the congured
wiring version (e.g., 568A) corresponds to the actual wir-
ing.

Storing Data
After the measurement has been completed, it can either be exited with ESC, or the Save Data
menu can be opened by pressing the SEL key. The predened name of the measurement – De-
fault – followed by a number is displayed here. If the data is to be assignable later, you will need
to enter a unique name here. We recommend customer names or a number. The entry is made
by pressing the ▲ or ▼ keys, which allows scrolling through the alphabet and the numbers from
0-9. Press SEL to insert the desired character. The cursor position can be changed with the ◄
and ► keys.
This name will remain entered until it is overwritten again. This means that, when saving the next
measurement, if the customer is still then same, nothing will have to be changed. The number
of the measurement will increase automatically. You can then sort, print, and save the data in
the KE7200 Manager PC software (see page 22) according to the customer number or the
name. It should be noted that it is necessary to adjust the memory setting at the start of a new
measurement series at another system.
The second line displays the available memory space. A total of about 14,000 entries are pos-
sible.
Cable/Wire Search via the Port Finder Function (link blink func-
tion) or Search Tone (tone mode) (Ethernet cable only)
The KE7200 has two ways of identifying a known socket at the patch panel, switch, or hub:
Portnder Function (link blink function)
Plug the test cable of the KE7200 into the socket located in the room and select the Link Blink
test in the Cable/Wire Search menu.
It is veried whether the socket is active in the network. This is displayed in the status line of the
KE7200. When the connection is active, information about the Ethernet connection with the re-
spective detected speed is displayed. The associated port on the patch panel/router/hub/switch
will ash.1
If the port is not active, No Connection will be displayed. Then you will need to proceed with
tone mode.
Search Tone (tone mode)
Then you can switch to the tone mode in which one of 4 tones (1000 Hz; 880/1000 Hz; 2600
Hz, and 2600/1900 Hz) is transmitted to all wire pairs by the KE7200. The P310 probe can then
be used to search for the search tone at the patch panel/router/hub/switch and to unequivocally
identify the associated network port.

PoE/PoE++ Test (according to IEEE802.3af/at/bt)
(Ethernet cable only)
Connect the KE7200 to the network. Start the test with the SEL key. The KE7200activates the
PoE port and outputs the corresponding information in the display regarding whether PoE/PoE+/
PoE++ is present or not.
The PoE standards are displayed according
to the expected nominal voltages.
Higher voltages (fault conditions) can dam-
age the instrument and pose a potential
safety hazard.
If PoE can be activated, this will happen. To begin with, the
max. load is applied to remove the cable charge. The max-
imum available power is then measured according to the
IEEE802.3af/at/bt standard. This regulates which voltage
must be present on the line when a certain current is owing.
If this voltage is below the standard value, the KE7200 will switch the load back until the voltage
is within the normal range again.
This power is calculated and then displayed. This information is important in any network with
PoE subscribers, as disturbances will occur again and again due to the load on the power supply
in the switch being at the limit. If a small additional load is now added, such as due to changed
operating conditions like the switching on of infrared illumination, the network will collapse and
the switch will only supply the emergency power. This cannot be detected without appropriate
test equipment. Some PoE switches also provide 30 W per port. These then work outside the
specication.
The test will need to be restarted for each measurement.
IP Test, Including Network Speed and Ping Test
(Ethernet cable only)
During the network test, the KE7200 can search the network
for IP addresses and thus subscribers. This can be done in
DHCP mode or with a xed IP address. If the network also
monitors MAC addresses, the MAC address of the KE7200
can be adapted (see page 12).
The DHCP mode is rst activated by selecting IP Test >
DHCP Request. As soon as a network connection is estab-
lished, it is displayed in the status line, and the IP address
assigned to the KE7200 by DHCP is displayed. The request
for occupied IP addresses in the assigned address space
starts immediately. The number found is also displayed.
The KE7200 now queries all addresses for information and lists it. If names are available, they
are displayed – if not, only the IP address.
This process can take some time, especially if there are many subscribers in the network. You
can see the progress by the change in the IP addresses found. At the top of the screen, Net-
work is displayed. Selection with SEL shows general network information such as Connection
Speed, own IP Address, and Network Mask. The ▼ key scrolls to the next page. This will
display the following:
• Domain name of the network
• IP of the DNS server
