A: Hello, This USB decoder alone is not sufficient for you to capture and decode BACnet/MSTP packets. In order to do this, you would need the BAS-o-matic along with the U+4 hardware. The two products with the links are below https://www.cimetrics.com/collections/bacnet/products/b5020-bacnet-protocol-analyzer and https://www.cimetrics.com/collections/bacnet/products/b2110-bacnet-mstp-interface Hope this helps Thank you
