• LoRa LR-201-E- Modbus

LoRa To Ethernet (Modbus TCP) Gateway

Model : LR-201-E-Modbus
 It work with Modbus protocol but not work with LoRaWAN.
 The devices to be used in a loop group for data transmission. It is like an RS-485 in semi-duplex but wireless.
 In the loop group just pick one LoRa device to work as a MASTER and the other LoRa devices are SLAVE.
 These devices have general LoRa features such as long range, low packet size and loose in data collecting.
 We recommend the packet not over 100 bytes per second and the condition could accept data lost.
 Generally it work good for environment data collection to get long trend. It’s not suitable for instant On/Off work.
 Distance of LoRa transmission is long range subject to antenna to be Line-Of-Sight from Master to Slaves.
