In the above three working modes, MDL311 can send and receive data, and the parameters mentioned above are measured data. LoRa technology has high recei sensitivity (RSSI) and signal-to-noise ratio (SNR), coupled with our proprietary modulation and demodulation technology, LoRa wireless product has strong anti-interference ability and stable and reliable product performance. Wiring port MDL311 provides two kinds of power interface, two kinds of power interface can only choose one to use, cannot be connected at the same time. Vin+ GND: The power supply voltage range of this interface is DC 5 ~ 30V; BAT+ BAT-: The power supply voltage range of this interface is 3.4~4.2V. Serial Port RS232 (RXD, TXD, GND) and 485 interface are marked on the panel, and only one of them can be choose; If it is used at the same time, it is necessary to ensure that two serial ports of DTU are staggered in the time of recei serial port data, otherwise there will be conflicts. MDL series product adopts 32-bit ARM low-power CPU, and the unique RF communication technology of Mind technology, which makes the product standby current less than 50uA. At 50uA power consumption, MDL device is still in the working state and can receive and send data at any time, which is not the power consumption under sleeping. *The above all data is measured in "power priority mode". Flexible and powerful AD-hoc network Broadcast communication In the same network, each device communicates with each other. Point-point communication In the same network, point- point communication between any two devices can be realized. Multicast communication In the same network, single or multiple devices can be set as a group to realize communication between groups *The above three networking methods can be combined in the same network. *MDL311 coordination 4G DTU can easily set up LoRa gateway and realize remote data transmission. In addition to using local serial port line to configure parameters directly, Mind LoRa equipment also supports wireless configuration of remote device parameters. As shown in the figure above: Device A is connected to the computer through serial port cable. Using the graphical configuration software provided by our company, the parameters of local device a can be configured conveniently and quickly, and the parameters of remote device B can also be configured by the wireless network. *To configure parameters in wireless mode, it is necessary to ensure that the local device and the remote device are in the same network.
