    16. • Distech Controls recommends that you connect no more than 50 of our ⅛ or ½-load devices on a single BACnet MS/TP Data Bus Segment when a baud rate of 19 200 or higher is used (preferably 38 400 baud). This is to ensure that the BACnet MS/TP Data Bus has enough bandwidth to efficiently communicate network variables between control- lers.

  • Page 17: Device Loading

    The use of full load devices limits the number of devices connected to a BACnet MS/TP Data Bus Segment to 32 devices. Distech Controls' BACnet MS/TP devices are ⅛-load devices and ½-load devices, which allows more devices to be connected to the BACnet MS/TP Data Bus Segment, as compared to full load devices.
