The BMG is a network gateway module which routes communication traffic between BACnet Ethernet network and Modbus RTU network.
The gateways, pre-loaded with a Modbus program, become masters to the connected Modbus slave devices and communicate using the Modbus RTU protocol on a RS-485 network.
Each gateway is available with two RS-485 networks. Each network can support up to 32 Yoof Controls NT10, NT50, NC24A, NC24T or NSM Modbus RTU devices. These devices must not be mixed in both network trunks and must be of the same series or type.
