-139dbm high receiver sensitivity data transmission embedded LoRa DTU module
The LORA DTU module_MDL210 embedded terminal is the one that uses LoRa spread spectrum technology for wireless data transmission, providing users with a protocol-free fully transparent data transmission mode. You only need to set a few simple parameters to achieve multiple modes of networking such as star networking and Mesh network. There are also multiple communication modes such as on-demand, broadcast, and multicast in the same network;
TTL communication interface is provided , User-friendly industrial serial port equipment networking, equipment power supply adopts a wide range of low power consumption design(≤40uA@5V).
LoRa technology itself has super high recei sensitivity (RSSI) and
super signal-to-noise (SNR) plus our proprietary modem support technology and stable and reliable product performance.
The LoRa wireless module has a very strong anti-interference ability.
MDL210 cooperates with our company's 4G DTU, which can facilitate the establishment of LoRa gateway to realize remote data transmission.
Broadcast communication
Under the same network, each device communicates with each other
Point - Point communication
Under the same network, point- point communication
between any two devices can be realized
Multicast communication
Under the same network, single or multiple devices can be set as a group to realize group-to-group communication
The above three networking methods can be combined in the same network
In addition to using the local serial cable to directly configure the parameters of MIND LoRa device, it also supports wirelessly configuring the parameters of the remote device.
As shown in FIG:
The A device is connected to the computer through a serial cable, and the graphical configuration software provided by our company can be used to configure the parameters of the local device A conveniently and quickly, and the parameters of the remote device B can also be configured wirelessly.
*To configure parameters in wireless mode, ensure that the local device and the remote device are in the same network
