Wireless Modbus RS485 - IEEE 802.15.4 2.4 GHz Bridge
Product Model: DM-124

Main Features

The main role of the DM-124 is to act as a IEEE 802.15.4 wireless bridge inside traditional wired RS485 Modbus RTU installations, providing the limited point-to-point RS485 networks with the versatility and ease of installation of wireless sensor networks (WSN).

The DM-124 is auto configurable, which means that each node automatically selects the best route to forward the data packets, effectively disseminating the Modbus commands to all connected devices.

Its power supply range from 110Vac to 230Vac easing its installation in any location with electrical power, avoiding the use of any external power supply.

Once installed, the DM-124 are transparent to devices inside the RS485 network, not only maintaining the electric requirements of the bus but also the integrity of Modbus RTU packet frames transmitted.

  • Wireless communication based on IEEE 802.15.4 (2.4 GHz)
  • Auto configurable
  • Modbus RTU wireless transmission
  • 110-230 VAC power input
  • DIN-Rail device
  • Easy connection (Modbus A- and B+ terminals)
  • Configurable pulse counter, with 3 operating modes: Dry-contact, Open-collector, S0 type (gas and water counters)
  • Coordinator node - Modbus Bridge within ADVANTICSYS Wireless Sensor Networks

Our WM Config Tool eases the configuration process either through RS485 or radio. User Manual and latest version is available in our Tech Resources wiki page.
