> MAC Address
The KE7200 is shipped with a predened MAC address. In order to work in networks with MAC
address verication, the address can be freely dened 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
suciently 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.
