DANEO 400

Single DANEO 400 with implicit synchronization
The acquisition of network traffic at different ports of the one DANEO 400 unit is time aligned, that is,
the time stamps assigned to packets captured from different ports represent the exact relative timing.
When the absolute time of the capture is of no relevance and the relative timing between packets
needs to be evaluated, simple connection options without synchronizing to absolute time can be used.

All Ethernet ports are used in the primarily intended way. The unit is controlled via the ETH
control port; two streams of traffic are captured via the process ports A and B.
Even in a local network, considerable distances can be spanned by such a configuration. As the
length of an Ethernet segment can be up to 100 m, the two locations where the data are captured from
can be up to approximately 200 m apart, if DANEO 400 can be conveniently located at the middle
between the capture locations and if Ethernet cables of sufficient length are available.

Control via ETH over network, capturing on A and B

The PC with the control SW is not directly connected to DANEO 400. The control traffic is also
forwarded through the network, so the controlling PC can be located independently of DANEO 400. This is a

scenario that also works when the network connection is established over a WAN.
