  • BACnet MSTP optimal baud-rate selection using auto baud feature
    Patent number: 11539639
    Abstract: Apparatus and associated methods relate to selection of an operating baud rate for a building automation system that communicates over a Master-Slave Token-Passing (MS/TP) BACnet. A server (or router or gateway) connected to the MS/TP BACnet is programmed to iteratively select operating baud rates from a series of available operating baud rates. Each iteration, the server broadcasts a frame indicating baud rate selection to a plurality of building automation devices connected to a MS/TP BACnet. Each of the plurality of building automation devices connected to the MS/TP BACnet then iteratively sets its baud rate so as to match the baud rate selected by the server. The server monitors communications conducted over the MS/TP BACnet so as to determine reliability or unreliability of the communications conducted over the MS/TP BACnet using the baud rates iteratively selected. A highest reliable baud rate is then used by the building automation system.
