W-BACnet module

W-BACnet replaces the cabling with a reliable wireless mesh eliminating the time-consuming installation planning, cabling, daisy-chaining and trouble-shooting.

The W-BACnet OEM Module can be integrated directly into a BACnet MSTP device in order to make it wireless. Simply connect the UART interface of the Module to your host CPU to communicate BACnet MSTP. The Module also have a SPI Slave interface for configuration, putting your device in control so the Module can be adapted to your already existing user interface.

The W-BACnet acts as a proxy for the connected BACnet MSTP device, effectively extending the bus and creating the possibility to make legacy products wireless. A W-BACnet network consists of a single W-BACnet Gateway with up to 100 W-BACnet Nodes. Connect your BACnet MS/TP controller using RS485 to the W-BACnet Gateway, and then each of your BACnet MS/TP devices with RS485 to the W-BACnet nodes.

System overview

A W-BACnet network consists of a single W-BACnet Gateway with up to 100 W-BACnet Nodes. Connect your BACnet MS/TP controller using RS485 to the W-BACnet Gateway, and then each of your BACnet MS/TP devices with RS485 to the W-BACnet nodes.

The W-BACnet network is built on LumenRadio’s MiraMesh, a self-forming and self-healing wireless mesh technology.

FAQ

How do I set serial settings for the W-Modbus Module?

The Module have a SPI Slave interface for configuration, please see the development documentation for further information.

Is the BACnet communication via UART to the W-BACnet Module?

Yes, UART is used for all communication between thes Module and the BACnet device. It is also support for using a RS485 driver.
