Johnson Controls N2 Driver for Tridium Niagara

The Johnson N2 driver for Tridium Niagara provides a comprehensive solution for integrating Johnson Controls’ legacy building automation systems into the modern Niagara Framework, ensuring compatibility and enhanced system longevity. This driver connects older Johnson N2 devices with the modern capabilities of Niagara-based platforms, allowing users to continue using their existing systems while gaining access to advanced automation features.

The Johnson N2 driver improves interoperability between different systems, reducing fragmentation in building operations. By integrating HVAC, lighting, and other automation components, it enables unified control and monitoring, leading to better resource management, increased efficiency, and less manual intervention. This integration results in energy savings, improved reliability, and better utilization of building resources. The driver simplifies the process of connecting legacy N2 networks with modern technologies, allowing upgrades without the need for major infrastructure changes.

The Johnson N2 Niagara driver works with the Johnson Controls Metasys network, using both the N2 proprietary protocol and the N2 Open protocol, originally based on the OPTO-22 optimux protocol and extended over time to support System-91 and N2B variants. This allows the driver to communicate with a variety of devices, including third-party systems. It uses RS-485 communication at 9600 baud, enabling straightforward connection of multiple devices. The driver supports analog and binary data types, and multiple internal data formats. It also handles regular polling and direct command communications, simplifying integration and management of devices across the network reliably.

The N2 can be used across healthcare, education, and commercial settings to enhance environmental control, optimize energy efficiency, and improve overall building automation. In healthcare facilities, it ensures precise control over temperature, humidity, and ventilation to maintain safe and comfortable environments for patients while adhering to regulatory standards. In educational campuses, it streamlines energy consumption management, providing reliable comfort for students and staff across classrooms, laboratories, and common areas. In commercial settings, the driver enhances energy monitoring, supports sustainability goals, and helps maintain a comfortable environment for occupants, ensuring efficient and seamless building operations.

The Niagara Framework, developed by Tridium, is an open platform that integrates diverse building automation systems and devices into a unified, easily managed solution. Niagara enables seamless communication and control of various components, including HVAC, lighting, and energy systems, using standard communication protocols. It supports comprehensive data visualization and analytics, enabling facility managers to optimize building performance. Niagara’s flexibility and open architecture make it an ideal choice for retrofitting legacy systems and integrating new technology into existing infrastructure.
