SCB111-485-NB-DC
  1.  Outdoor NBIoT Sensor Gateway Modbus RS485 to NB-IoT / LTE Cat M1

The SCB111-485-NB-DC gateway facilitates communication between RS485 RTU devices or sensors and cloud servers using the CAT M1 or NB-IoT cellular network. It securely transmits data in JSON format and MQTT protocol with AES128-bit encryption. The gateway's configuration is by a MicroUSB connection with Windows utility. The device supports up to 20 Modbus slave devices and allows for 80 Modbus Registers polling and sends the data to the cloud server in four MQTT messages. The device is compact, palm-sized, and weatherproof with an IP68 rating, allowing it to operate in outdoor environments with temperatures ranging from -40 ~70˚C. The Firmware upgrade can be made by air (ThingsMaster OTA, FOTA), which is ideal for large scale outdoor Industrial IoT applications.
