CAS BACnet Explorer uses a 3rd party network library called Winpcap to help with the low level networking. Its the same network library that is used in Wireshark. You network card must be supported by Winpcap to be able to use the CAS BACnet Explorer. 99% of all network cards should be supported with the exception for a small selection of wireless network cards.
Wireless adapters: these adapters may present problems, because they are not properly supported by the Windows Kernel. Some of them are not detected, other don’t support promiscuous mode. In the best case, WinPcap is able to see an Ethernet emulation and not the real transiting packets: this means that the 802.11 frames are transformed into fake Ethernet frames before being captured, and that control frames are not received. Again, refer to the http://www.micro-logix.com/WinPcap/Supported.asp to discover if your adapter works. If it doesn’t, you can use the trick explained in this video to capture its traffic.
If you can not detect any network devices on the Settings->Network dialog in CAS BACnet Explorer your network device may not be supported by Winpcap or more likely you are not running the CAS BACnet Explorer as an administrator.
To run CAS BACnet Explorer as an administrator
1) Right click on the CAS BACnet Explorer.exe and select “Run as administrator ”
