Μετατροπέας RS485 σε LoRaWAN DRAGINO RS485-LN-EU868 (EU868)

DRAGINO RS485-LN-EU868 is an RS485 to LoRaWAN converter designed for EU868 band networks. It enables RS485 devices such as sensors, meters and legacy controllers to transmit data over LoRaWAN, providing long-range, low-power wireless connectivity for remote monitoring and control. The converter supports transparent serial forwarding between RS485 and LoRaWAN network servers and is intended for integration into industrial and commercial IoT systems.

Advantages

The device offers reliable conversion between RS485 serial communication and LoRaWAN, reducing the need for wiring and enabling remote data collection across wide areas. Its support for the EU868 frequency band ensures compatibility with regional LoRaWAN deployments. Designed for simple network integration, the converter minimizes configuration complexity while preserving RS485 electrical characteristics and communication timing.

Suitable for

• Connecting industrial sensors and meters to LoRaWAN networks
• Remote monitoring of legacy RS485 equipment
• Energy and water meter reading over long distances
• Environmental and agricultural sensors in wide-area deployments
• Building automation where wired RS485 devices need wireless backhaul

Key specifications

• Interface: RS485 serial port for device connection and LoRaWAN radio for uplink/downlink
• Frequency band: EU868 regional LoRaWAN band compatible
• Communication: Transparent serial forwarding between RS485 and LoRaWAN network servers
• Power: Low-power design suitable for continuous operation with minimal energy consumption
• Range: Long-range LoRaWAN radio suitable for wide-area coverage subject to local environment and gateway placement

How to use

Install the converter near the RS485 devices and connect the A/B terminals to the RS485 bus following proper wiring polarity and termination practices. Configure the device with LoRaWAN network parameters for the EU868 band via the supported configuration interface or provided utility, including network keys and device identifiers as required by the LoRaWAN network server. After provisioning, the converter will forward RS485 serial data as LoRaWAN uplinks and receive downlinks to be sent back onto the RS485 bus, enabling remote reading and control through the network server.

Recommendations

Place the converter where radio signal strength to a LoRaWAN gateway is adequate; avoid metal enclosures or locations with heavy RF attenuation. Use recommended RS485 termination and shielding practices to maintain signal integrity. Validate baud rate and serial framing settings of connected devices to ensure correct transparent forwarding. Consult local LoRaWAN network rules for duty-cycle and transmission power limitations in the EU868 band.
