RS-485 to LoRaWAN converter-transmitter

RS-485 to LoRaWAN converter, pulse counter and safety sensor. All combined. Two pulse inputs, each of which can be configured as a safety / digital input. External power supply. RS485 transmitter to LORAWAN


The RS485 to LORAWAN converter-transmitter allows transparent transmission of RS485 frames. These frames are stored in transmitted at regular intervals. If the frame is larger than the LoRaWAN frame, the data is transmitted in several separate packets. It actually acts as a “transparent” modem operating in LORAWAN class C mode (supplied with external electricity). The LORAWAN converter transfers this serial command to the connected counter / machine. If a response is received, the converter returns it as one or more LORAWAN uplink messages. In pulse counting mode, the pulse counter counts electrical pulses at a maximum frequency of 200 Hz. It is possible to configure the frequency of transmission of frequency data from the meters independently, between 5 minutes and 24 hours. The pulse counter supports the “Open Collector” circuit type.

In dry input mode, the pulse counter generates a LORAWAN message when the circuit is open or closed (or in both cases).
The pulse counter also transmits the ambient temperature and the level of its battery.

The configuration of the sensor is done via a USB connection via a free PC application. Or by LORAWAN downlink message.

About LoRaWAN

The LoRa network, also called LoRaWAN, is a dedicated Data network for IOT sensors. It provides small data transmission on large distances – up to 15 km, while consuming very limited energy, allowing sensors to be operated on small batteries.


  • In Belgium and Luxembourg, Proximus operates a nation wide LoRaWAN network.
  • In France, Orange and Bouygues operate a LoRaWAN network.
  • In the Netherlands, KPN is the main LoRaWAN operator.
  • In Switzerland, SwissCom is the main LORAWAN operator
  • LoRaWAN is available in most Countries (Spain, Andorra, Italy, Bulgaria, Czech Republic, UK, Ireland, Iceland...). Worldwide.

If there is no LoRaWAN coverage in your country/region, it is also possible to deploy a private LoRaWAN network.

Contact us if you have questions about the LORAWAN coverage in your region.
