BACnet MS/TP Network Connections & Information
Based on the standards for RS485 networks, a BACnet MS/TP network layer allows for only a daisy-chained network
configuration, consisting of a single cable routed between controllers.
Note: Star and Ring network topologies are not
supported.
The network electrically supports a maximum of 127 nodes, however BUS network size capability is determined by factors
such as network traffic and BMS capabilities and Titan Products recommend maximum network size of 64 devices.
To comply with the EIA-485 standard, the maximum number of nodes per segment shall be 32 and any additional nodes
will require the use of repeaters. If only Titan controllers are on the MS/TP network, the number of controllers may be
increased but this will depend on the network traffic, the baud rate being used and the length/route of the cable.
A termination resistor of 120 ohms should be connected at each of the end devices. Bias resistors should be used to bias
the network at either a single point or at each end of a network segment.
Note: End of line resistor optional selection within NetMaster software
