3 Introduction
The KUNBUS TAP CURIOUS is your network monitor for analyzing all standard
industrial Ethernet solutions. Four probe ports allow you to capture up to two
independent realtime Ethernet connections.
You can use filters to reduce data volumes or select specific analysis data. You
can configure these filters via an integrated web server. The web server can
operate in 2 different modes. "Basic" mode helps you set your filters and configure
your device. "Expert" mode was developed for people with expert knowledge of
frame filters. In this mode, you can filter a frame by all the aspects it contains.
The digital input and output allows you to create useful trigger conditions. These
can systematically help limit sporadic effects, and identify and remedy the causes.
An internal throughput delay of 0µs (zero delay) makes TAP CURIOUS almost
transparent for the data channels to be checked.
TAP CURIOUS is connected to a PC via a standard Ethernet interface. You can
operate TAP CURIOUS in 1 Gbit/s or 100 Mbit/s mode. Captured packet data is
read and analyzed using network monitors such as "Wireshark", the freely
available network analysis software.
