Instructions

Connect your devices as shown to monitor the frames before and after a device
throughput. In this example, device 2 is monitored. Here, you could analyze the
following: measure the device throughput time, check whether frames have been
distorted or truncated, measure jitter on cyclical frames.
Desktop PC / Laptop
Device 1 Device 2
Connect your devices as shown to capture the communication between two
devices. This allows you to find faulty frames on the network.
Application examples
TAP CURIOUS is able to monitor devices in various ways.
Example 1
Desktop PC / Laptop
Device 1 Device 2
Device 3
Example 2
• Unpack the device.
• Connect the device to the mains cable supplied.
• Load „Wireshark“ network analysis software onto the PC and install it. You
can download Wireshark from www.wireshark.org.
• Download Wireshark plugin.DLL from KUNBUS website and copy the file into
the Wireshark plugin folder (e.g.: C:\Programs\Wireshark\plugins\1.10.2).
Download the correct DLL file for either the 32 or the 64-bit Wireshark version,
depending on which one you use:
• 32-bit version: tap32_1xxx.dll (Wireshark-Plugin WIN32) *
• 32-bit version: tap32_2xxx.dll (Wireshark-Plugin WIN32) *
• 64-bit version: tap64_1xxx.dll (Wireshark-Plugin WIN64) *
• 64-bit version: tap64_2xxx.dll (Wireshark-Plugin WIN64) *
• Connect TAP CURIOUS to an Ethernet interface on the PC using a RJ45 cable.
„Link“ LED lights up as soon as the PC and TAP CURIOUS are connected.
• Connect the line to be tested to one of the probe ports. Each of the ports
„Con A“ and „Con B“ and ports „Con C“ and „Con D“ are connected directly.
So communication is possible even when TAP CURIOUS is powered off. The
speed LEDs show the connection speed set for the probe ports. When frames
are being transmitted on the line, the „Activity“ LED flashes green.
Starting the device for the rst time
• All available Ethernet interfaces are listed in the main window. Click on the
Ethernet interface you require to select it.
• Set any filters you want via the web server. This allows you to search for
specific frames and prevents your PC‘s main memory from becoming
overloaded.
Wireshark plugin
• Start Wireshark on the PC and activate the „TAP“ plugin in the menu at
„Edit > Preferences > Protocols > TAP“.
TAP CURIOUS expands the Ethernet packages by 20 bytes of additional
information. You can use TAP CURIOUS without the plugin or with a different
Ethernet analysis program. But you will not be able to analyze this additio-
nal information. You might also find that the analysis program reports a data
package as faulty due to this additional information.
You can now use Wireshark to analyze the data.
Power LED lights up.
* xxxx denotes the version used (e.g. 1.10.2)
