1Overview
The LM LoRa Master Controller and LC LoRa End-Node series utilizes the latest Low Power Wide
Area (LPWA) technology to build Modbus/RTU communication for long-distance, wide-coverage,
and low power consumption wireless IoT applications.
Multiple analog inputs and outputs are supported in LC100 series, such as voltage inputs and
outputs, current inputs and outputs, PWM output and one RS-485 port for Modbus RTU slave.
One LM100 RS485 Modbus RTU can connect up to 250pcs LC100 LoRa end nodes for two-way
communications where field site analog signals are sent from LC100 and controlled by LM100.
The LR100 series support LoRaWAN protocol, and also utilizes LPWA technology to build one way,
long distance communication coverage with LoRa WAN Cloud Gateway for filed RS-485 RTU slave
device connect with IoT Cloud Service.
Although the radio transmission technology is same, the LM100, LM200 and LC100 are utilized
proprietary protocol based on LoRa MAC and different with LR100 standard LoRa WAN protocol.
The LoRa wireless distance can reach up to 3-6KM distance depending on the environment.
The LM100/LC100 series offers great flexibility in wireless IoT applications, such as LED light
control, environment sensors and meters reading for Smart City Applications such as Lighting,
Smart Farming, Smart Environment Monitor, etc.
