GRP-540M-NB



Data Sheet(PDF)

The GRP-540M-NB provided by ICP DAS is a NB-IoT gateway for Ethernet and serial port. It can be used in M2M application fields to transfer the remote I/O or Modbus data via NB-IoT. Within the high performance CPU, the GRP-540M-NB can handle a large of data and are suited for the hard industrial environment. When connecting with NB-DA Server or MQTT Broker, the user can also control the devices which connected to GRP-540M-NB from the remote control center.


      Features      
  • Support NB-IoT
  • 10/100 Base-TX compatible Ethernet controller
  • COM port: COM1 (3-wire RS232), COM2 (3-wire RS232), COM3 (RS-485)
  • GPS: 32 channels with All-In-View tracking
  • Support Modbus RTU/TCP
  • Support MQTT
  • Support Micro SD card

   Software Solutions    
The NB-DA Server is a software with friendly graphic interface to collect data from ICP DAS IoT devices. It provides four interfaces—Modbus TCP, MQTT, Database, and RAM Disk (.csv file) to let user gets the data. Besides, user can use Modbus TCP command or publish MQTT message to control remote I/O. In the NB-DA Server, user can set multiple stations to collect data in different applications and every station can support 2000 devices online
