The Dragino RS485-LB is a RS485 / UART to LoRaWAN Converter for Internet of Things solutions. User can connect RS485 or UART sensor to RS485-LB converter, and configure RS485-LB to periodically read sensor data and upload via LoRaWAN network to IoT server.
RS485-LB can interface to RS485 sensor, 3.3v/5v UART sensor or interrupt sensor. RS485-LB provides a 3.3v output and a 5v output to power external sensors. Both output voltages are controllable to minimize the total system power consumption.
RS485-LB is IP67 waterproof and powered by 8500mAh Li-SOCI2 battery it is designed for long term use for several years.
SRS485-LB runs standard LoRaWAN 1.0.3 in Class A. It can reach long transfer range and easy to integrate with LoRaWAN compatible gateway and IoT server.
For data uplink, RS485-LB sends user-defined commands to RS485 devices and gets the return from the RS485 devices. RS485-LB will process these returns data according to user-define rules to get the final payload and upload to LoRaWAN server.
For data downlink, RS485-LB runs in LoRaWAN Class A. When there is downlink commands from LoRaWAN server, RS485-LB will forward the commands from LoRaWAN server to RS485 devices.
RS485-LB Supports BLE configure and wireless OTA update which make user easy to use.
Each RS485-LB pre-load with a set of unique keys for LoRaWAN registration, register these keys to LoRaWAN server and it will auto connect after power on.
