Wireless RS485 Transceiver

AcuMesh Wireless RS485 Network

The Acumesh Wireless RS485 connects any device with a RS485 port to form a point to multi-point mesh network. It is ideal for buildings and systems that monitor energy flow, industrial automation and campus facilities. AcuMesh transceiver eliminates the usual wires in a RS485 installation by using a flexible and simple wireless communication solution.
  • Available in both 900MHz and 868MHz frequency
  • Automatic connection without any configuration or software
  • Compatible with any protocols: Wireless Modbus RTU, Profibus, DNP 3.0 and more
  • Highly secure 128-bit Advanced Encryption Standard (AES)
  • Advance configuration available for complex network setup with free software
  • 1000 ft (305m) indoor / 4 Miles (6.5km) outdoor in a single hop
  • Each transceiver acts as an extension point for the network allowing for a longer range of communication
  • Point to multi-point communication enabled with “mesh” structure
  • Self-healing and optimizing communication pathway

AcuMesh Wireless Advantage

What is a Mesh network and why it is better than the traditional wired method


AcuMesh Wireless RS485 Network

AcuMesh keeps all the advantages of a RS485 network but eliminates the wires. Each RS485 device connects directly with an AcuMesh transceiver allowing point to multipoint wireless communication with Master and Slave devices.

The AcuMesh transceiver supports all RS485 communication protocols (i.e. Wireless Modbus RTU, DNP 3.0, Profibus and more).

Wired RS485 Serial Network

Conventional wired RS485 networks come with inherit limitations during installation. Devices are networked together in a daisy chain topology increasing the budget and lifecycle of the project. Once installed in the facility it may be difficult to upgrade or modify and sometimes it may not be possible at all without incurring hefty expenses.

Advantages of Wireless Network:

  • Reduce network implementation cost for wired networks
  • Get a communication range of over 6,000 meters
  • Flexible network reducing infrastructure dependency
  • Simpler to maintain and upgrade once network is installed
  • Achieve faster development cycles by eliminating wires
