BACnet Router

A Versatile Interoperability Solution

BACnet Router

Sierra Monitor's BACnet Router product offers a complete BACnet internetworking solution for BACnet/IP, BACnet Ethernet, and BACnet MS/TP networks, while also providing a secure connection to the cloud. Multiple BACnet routing connections can be established:

  • BACnet MS/TP to BACnet/IP
  • BACnet MS/TP to BACnet Ethernet
  • BACnet MS/TP to BACnet MS/TP
  • BACnet/IP to BACnet/IP
  • BACnet/IP to BACnet Ethernet

The FieldServer BACnet Router has dual BACnet MS/TP ports with a Wi-Fi option for a BACnet/IP connection.

Innovative Features

The dual-port BACnet Router has two RS-485 ports, enabling connection to up to 64 BACnet devices without the use of additional line drivers. Using a BACnet router frees up valuable RS-485 ports on expensive BACnet Controllers and reduces the cost of connecting BACnet MS/TP devices to a BACnet/IP backbone. Compared to single-port BACnet routers, our dual-port BACnet router can reduce the cost of device connectivity or double the speed of connected devices (half the response time).

BACnet Explorer, our unique discovery feature, allows the integrator to discover all the BACnet devices connected to the router with one push of a button, minimizing the time required for successful commissioning. Complementing this feature is our diagnostic FieldServer Toolbox, which allows the user or integrator to view the status of and diagnose all the routers on the network.

1. SMC Device Cloud support

Register your BACnet Router to the SMC Cloud interface for remote access to local applications, configuration, and device management

2. BACnet Explorer

Minimize commissioning time by automatically discovering all BACnet devices connected to a BACnet network.

3. BTL Certification

Most compliant and highest quality BACnet stack enables interoperability and reduces troubleshooting time

4. Dual RS-485 Port Option

Results in lowest cost per connected device or highest performance (response time) per connected device

5. Easy Configuration with Discovery

One page set and forget configuration along with unique network discover capability minimizes the integrator's installation time.
