8864 Data Controller

The hard-working 8864 Data Controller accurately and securely
acquires, stores and protects your CEMS data from
communications failures with your DAS system.

Collect, monitor, QA, and report on emissions data from continuous monitoring systems with confidence.

The industry-standard 8864 Data Controller provides a reliable and powerful hardware bridge between StackVision™, Prism®, or other Data Acquisition System (DAS) software and an emissions monitoring rack. Its proven accuracy and durability over decades of use across the U.S. are second-to-none.

The device offers superior network security. Remote browser connections require HTTPS and remote terminal sessions utilize a secure SSH protocol.

The 8864 features support for 1000Mbps with consistency and reliability in high-traffic networks with complex network topologies. It can perform firmware upgrades in less than one minute.

See Relevant Data Immediately with Customizable Dashboards

The 8864 Data Controller is intuitive and ready to use. The interface includes customizable dashboards, so the most relevant data is easy to see. Users can design and manage their dashboards, set active and inactive colors, and import/export.

The fully integrated capacitive touchscreen allows users to operate it with screentap gloves. Use the onscreen keyboard for easy configuration.
