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.

• Language
  Select German (default) or English

• Units
  m (meters) or ft (feet)

• Battery type
  The KE7200 / KE7100 can be operated with 4 AA batteries, or 4 AA rechargeable batteries. Since the voltage is lower with rechargeable batteries, the capacity display can be changed to reflect primary batteries and rechargeable batteries.

• Back light
  Duration of back lighting each time a button is pushed in seconds. Set the time with the ▲ or ▼ button, select with SEL.

• Auto power off
  The time when the tester automatically turns off after the last button has been pressed. Set with the ▲ or ▼ button, select with SEL.

• Key beep
  On or off

• Sound
  On or off. This sound occurs when the cable test finishes.

• Contrast
  LCD contrast setting value, default: 14. Set with ▲ or ▼, confirm with SEL

• Reset to factory setting
  All of the settings are reset to the factory defaults.

• 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. 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+/PoE++ test per IEEE 802.3af/at/bt
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/at and to IEEE 802.3bt. 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.

“Network” is displayed at the top position. Press SEL to show general network information such as the connection speed, the actual IP address and netmask. Press the ▼ button to go to the next page. The following is displayed:
Domain name of the network
IP address of the DNS server
IP of the DHCP server
IP of the router

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.

Changing the battery

Changing batteries
First loosen the two bottom screws in the bottom bumper. Pull the bumper downward.
The four AA batteries are in a holder. Remove the old batteries and replace them with new batteries. Note the polarity. Do not combine new and old batteries. Always use batteries of the same type and date of manufacture.
Return old batteries to the supplier or a recycling facility.

Test settings

Cable definitions (Main menu>Setup>Test setups>Cable definition) You can enter the different types of cables used. The types which already have been entered can also be overwritten.
After selecting the cable type to be changed or the last position without an entry, select it by pressing SEL. The display shows “Name:”. You can enter a unique cable name. Fifteen characters are available. At the flashing cursor position, press the ▲ and ▼ buttons to scroll through the alphabet and the numbers 0-9 including a space. Select the character or number at the cursor position by pressing SEL. Once the name is entered, confirm it by pressing SEL.

The following appears:
“Velocity: xx%“. This is the percentage velocity of propagation (VP) in the cable in relation to the speed of light. Enter either the value indicated by the cable manufacturer, the previously determined value, or an approximate value. The value is approximately 64 – 68 for telephone and Cat3 cables, approximately 72 for Cat5/6, and approximately 77 for Cat6/7.
Note that the cable lengths can only be correctly measured when the VP is correct.

After entering the VP value, save it by pressing SEL. This allows you to quickly and easily predefine the cable types that are being used.
Wiring definitions (Main menu>Setup>Test setups>Wiring definition) You can add to the wiring versions used. E.g., “568B UTP”.
It is helpful if you write down the pin/pair assignment of the wiring version to be created.
Sixteen common versions are predefined. The abbreviations UTP, STP, and CR are described on page 10 under Wiring. The list appears after the menu item “Wiring definition” is selected. The first item is “NO TEST”. Do not change this one.

After selecting a wiring version to be changed or the last “NOT USED” item, the “Name:” menu appears You can enter a unique wiring name such as “568C.” Fifteen characters are available. At the flashing cursor position, press the ▲ and ▼ buttons to scroll through the alphabet and the numbers 0-9 including a space. Select the character or number at the cursor position by pressing SEL. Once the name is entered, confirm it by pressing SEL.

The “Connections” menu appears. The assignment PIN to PIN and wire pair can be made that corresponds to the wiring version. This assignment is needed for identifying split pairs and good/bad information after the test. The scroll bar is at

Select it by pressing SEL. You are then in the menu

“Connection to pin 1”
An option appears where you can select all 8 pins that can be assigned to pin

1. Press the ▲ and ▼ buttons to select the right pin and press SEL.
   You then go the menu

“Pair”
You can now assign the selected pins to a pair by pressing SEL.
You then go to the menu “Connections”

The assignment of the first pin is displayed. Press the ▼ button to move the scrollbar to the next item and continue as before with the assignment.
The assignments cannot be deleted. If you make incorrect assignments while practicing, you can correct them. As an alternative, you can select the item “Device settings/reset to defaults.” This resets all definitions that you have created.
