Bridge LR is a bridge that converts RS-485 physical environment to wireless long range network LoRaTM. The device is completely configurable by the PC application, used to setup any parameter of RS-485 serial port or LoRaTM radio.
The solution has a master bridge connected to RS-485 Modbus RTU master, and as many slave bridges as sensors we want to monitor. The communication between master and slaves is completely transparent to allow an easy installation. However, it is required to control the time between messages on transmission, and timeout time between Modbus master and final sensors. Recommended time for both parameters is 3 seconds.
Bridge LR has 1 km of indoor coverage and 20 of outdoor coverage.
Bridge LR 230 VAC
Bridge LR 12 VDC
