BACnet Master-Slave Kit
The iSMA-B-FCU device can work in defined networks, where one device is a master and remaining devices (slaves) follow the master’s parameters. The single master device can have up to 5 slave devices, and it is possible to share up to 100 points with them.
Note: This function is available only in the BACnet MS/TP protocol, using the RS485 port (COM1).
