<title>BACnet MS/TP Wireshark Live Capture</title>

<p><a href="https://www.wireshark.org/">Wireshark</a> 2.0 brought
|
||
some new features, including <a href=
|
||
"https://www.wireshark.org/docs/man-pages/extcap.html">extcap</a>.
|
||
Extcap allows an external application to capture packets and move
|
||
them into Wireshark via a pipe. It is the perfect feature for
|
||
serial packets, such as BACnet MS/TP on RS-485, which don’t have
|
||
a network interface.</p>
|
||
<p>How does it work? After installing version Wireshark 2.0 or
|
||
later, find the Extcap folder on your computer. The folder is
|
||
listed under Wireshark Help About Folders menu option.</p>

|
||
<p>Copy <a href=
|
||
"https://sourceforge.net/projects/bacnet/files/bacnet-tools/">mstpcap.exe</a>
|
||
into the Extcap folder (create the folder if it doesn’t
|
||
exist).</p>

<p>Run Wireshark, and notice the new BACnet MS/TP Interfaces
|
||
associated with each serial port.</p>
