Industrial BACnet routers – RS-485 to BACnet IP integration
Industrial BACnet routers (RS-485 to Ethernet)
This category includes BACnet IP routers designed to communicate with BACnet MSTP devices using an RS-485 serial interface. BACnet (Building Automation and Control Network) is a global protocol standard for building automation, facilitating communication between devices such as HVAC systems, fire alarms, lighting, energy meters, and other intelligent subsystems. BACnet routers act as bridges between BACnet MSTP and BACnet IP, enabling seamless integration with higher-level systems like BMS (Building Management Systems) or SCADA.
The implementation of BACnet routers simplifies the management of distributed automation infrastructures. By translating messages between MSTP and IP networks, these devices allow building administrators and integrators to monitor, control, and configure devices across protocols. They also enable event and alarm management, variable reading and writing, and interaction between different vendors’ BACnet-compatible equipment.
Features and functions of our BACnet routers
Our BACnet routers support BACnet MSTP communication over classic RS-485 screw terminals and BACnet IP over standard Ethernet RJ45 ports. Typically, a single router can handle up to 32 BACnet MSTP devices, but more advanced models may support higher limits depending on network structure and bus characteristics.
The routers operate with a wide input voltage range – most commonly 9–36VDC or 24VAC – and are available in versions designed for DIN rail mounting or flat surface installation. Their robust construction ensures immunity to industrial noise and resilience in extreme environmental conditions. Many models are certified for operation in outdoor enclosures and industrial control cabinets with exposure to frost or high temperatures, making them ideal for demanding projects.
All BACnet routers in our portfolio include configuration software free of charge. Depending on the manufacturer, this could be a proprietary application (such as ADFweb’s MAPS software) or a user-friendly built-in web interface, accessible via a standard browser. Setup usually involves just a few steps, and intuitive interfaces make integration quick even for less experienced technicians.
Some advanced models support BBMD (BACnet Broadcast Management Device), enabling BACnet communication across different IP subnets. This is crucial in large buildings or distributed campuses where devices are divided across VLANs or remote segments of the LAN. In addition, selected BACnet routers offer built-in diagnostics and a BACnet explorer tool, which allows for automatic device discovery, monitoring, and basic configuration from a single access point.
Our BACnet router range also includes products with official UL and BTL certifications, ensuring compliance with the highest international standards for reliability, interoperability, and safety. Certification is especially important in regulated industries and public infrastructure projects, where validation and audit trails are required.
BACnet routers are ideal for system integrators, HVAC professionals, building managers, and automation contractors who require reliable and standardized communication between legacy RS-485-based devices and modern Ethernet-based networks. Their deployment simplifies network design, reduces troubleshooting time, and increases the overall flexibility of building automation systems.
A typical application of these routers includes connecting fan coil units, VAV controllers, air handling units, and third-party meters into a central IP-based BMS. The router acts as a translator, allowing centralized systems to interact with each device individually – monitor its status, push new setpoints, or log historical performance data.
For engineers working on renovation or upgrade projects, BACnet routers provide a seamless way to modernize communication infrastructures without replacing existing MSTP devices. This approach is not only cost-effective but also minimizes downtime and installation complexity.
