Product description

W-BACnet simplifies BACnet RTU installations by replacing the control cable with a wireless connection. This significantly alleviates the downsides of running control cables, such as daisy-chaining, installation planning and troubleshooting.

The W-BACnet module is built on LumenRadio's MiraOS, which runs the MiraMesh network stack. MiraMesh is a self-stabilizing mesh network technology that uses patented technology to ensure highly reliable, and long-range wireless communication in noisy environments. W-BACnet uses the international license-free ISM band at 2.4 GHz, the same band used by WiFi and Bluetooth. But thanks to Cognitive Coexistence, our patented technology, our devices communicate reliably despite the noise generated by nearby devices.

A W-BACnet network consists of a single W-BACnet Gateway connected to the BACnet MS/TP device/controller using a UART/RS-485 cable and up to 100 W-BACnet Nodes, each of them connected to a BACnet MS/TP device.

W-BACnet System Overview

Features

  • Mesh Network – Cover an entire building by utilizing the mesh network as your infrastructure.
  • Self-stabilizing – The mesh network will continually search for the best route for packets between each device.
  • Cognitive Coexistence – LumenRadio's patented technology provides industrial- grade reliability and tolerance to interference.
  • Agnostic Communication – No need to have identical baud rate, parity, or stop bit configuration on each BACnet device in the same network.
  • Small footprint – 18.5 mm x 33.5 mm.
  • Antenna Connector – U.FL/IPEX.

  • Upgradable Firmware – Via BLE (Bluetooth Low Energy). - Multiple BACnet MS/TP devices – Up to 16 BACnet MS/TP devices are supported per W-BACnet Pro module.

  • Configurable via UART or SPI.
