Data Sheet

TAP CURIOUS is a mobile device designed to analyse all popular real time ethernet networks to the market. The
device’s main tasks include recording and analysing Delay, Jitter and CRC faults in the network. The device can
monitor up to two independent ethernet channels simultaneously in full duplex operation. Thanks to the completely
passive listening operation, there are zero delays and data communication in the network is not influenced.
The tapped data from the network is furni-
shed with a 20-byte long trailer (including
the time-stamp) and relayed via the existent
uplink port to a PC or laptop for further
analysis. The reading and evaluation of
the measured package data is done via
the freely available Wireshark software. A
plugin is available for a trouble-free soft-
ware integration.
In addition to the recording of faulty tele-
grams in the network by which the TAP is
installed between two devices (see Example
A), TAP can also be used to specifically ana-
lyse data streams of a device to be found in
the network (see Example B). In doing so,
TAP CURIOUS record the frames directly
before and directly after the device to be
analysed. This enables the measurement of,
amongst other things, the delay and jitter
of the device and whether, for example,
the device swallows or falsifies respectively
telegrams.
As a result of its compact and durable plas-
tic housing, the device is not only suitable
for work in laboratories but also for daily
use in the field.
Filter functions
TAP CURIOUS comes equipped with a
wide range of filter functions that assist
the specific search for specific values and
therefore significantly reduce the amount
of data to be analysed. Faults occurring in
the network can thus be found quicker and
eliminated. TAP CURIOUS filter functions
can be configurated easily and quickly via
the graphic, browser-based user-interface
of the TAP CURIOUS.
Trigger functions
By means of the available digital in and
output, it is possible to trigger particular
network conditions; ideal for specifically
narrowing down sporadically appearing
faults and then finding and rectifying them.
In addition to the digital output, there are
also five freely configurable LEDs available
to indicate optically, for example, the occur-
rence of a faulty transmission on the device.
The digital input for example ensures that
recording can be started at any point in
time.
100 Mbit/s and 10 Mbit/s mode
TAP CURIOUS can be operated in 100
Mbit/s and 10 Mbit/s mode. The mode can
easily be switched via the configuration
menu.
