Modbus TCP / BACnet IP to WAN MQTT Gateway GT200-MQ-BMT

2. Connect the gateway power interface to the power supply.

3. Connect the Gateway’s RJ45 interface to the computer with a RJ45 cable.
4. Power on the gateway. Run the SST-BMQ-CFG to start the gateway configuration.

Indicators	Function
MQ/N1 (Top Left)	Network status of MQTT and EtherNet 1
BI/N2 (Top Right)	Network status of BACnet IP and EtherNet 2
MS (Bottom Left)	Module Status
MT (Bottom Right)	Network status of Modbus TCP

Indicators	Status	Description
MQ/N1	Solid Green	MQTT connection established
	Flashing Green	Attempting to establish MQTT connection or connection disconnected
	Flashing Red	DHCP (EtherNet 1)
	Flashing Red	The IP address of EtherNet 1 is in the same subnet as EtherNet 2
BI/N2	Solid Green	BACnet IP connection established
	Flashing Green	Attempting to establish BACnet IP connection or connection disconnected
	Flashing Red	DHCP (EtherNet 2)
	Solid Red	The IP address of EtherNet 2 is in the same subnet as EtherNet 1
MS	Solid Green	Startup
	Flashes Green Two times, then Off	Restore factory settings through the button
	Solid Red for 500ms	Configuration is locked
	Solid Red and off alternatively	Configuration is unlocked
	Solid Red	Gateway Failure
	Solid Orange	Initialization
MT	Solid Green	Modbus TCP connection established
	Flashing Green	Attempting to establish Modbus TCP connection or connection disconnected
	Flashing Red	Reserved
N1 Orange and N2 Orange	All On	Startup Status
N1 Orange and N2 Orange	Alternate Flashing for 3s	Locating the gateway

1. Run the SST-BMQ-CFG software installed on your computer.
2. DoubleClick "BACnet IP" in the tree view on the left, set the Network and BACnet IP communication parameters. Remember: Two Ethernet cards cannot be set to the same subnet
3. Double Click "Modbus TCP" in the tree view on the left and set the Modbus TCP protocol communication parameters.
4. Add node and commands under the "Modbus TCP".
5. If you need to upload the collected data to MQTT, you can configure the corresponding parameters and add mapping relationships in "Fieldbus to MQTT". The MQTT function can only use network card 1 for communication.
6. You can add mappings in the"Fieldbus to Fieldbus" for BACnet IP and Modbus TCP conversion.
7. Click download button, select the correct serial port number and then click on "Download".

For more information, please refer to the GT200-MQ-BMT manual.

1. Connect BACnet IP client or Modbus TCP devices to the gateway's Ethernet interface. Please refer to the gateway manual for specific connection methods.
2. Observe the indicator lights to check the communication status.
