Maestro Digital Mine introduces PoE-enabled SuperBrite Marquee Display for underground mining
Extending electrical power underground is one of the most complex, costly and safety-critical aspects of deploying digital infrastructure in mining environments, and Maestro Digital Mine is addressing that challenge with the launch of its Power over Ethernet (PoE)-enabled SuperBrite Marquee Display.
By delivering power and real-time data over a single Ethernet cable through Maestro’s Plexus PowerNet communications system, the display eliminates the need to run high-voltage AC power to each unit, simplifying installation and reducing electrical risk underground, the company claims.
In underground operations, installing traditional AC-powered digital signage often requires certified electricians, additional panels and breakers, safety inspections, and production interruptions that increase project scope, cost and scheduling complexity. PoE significantly lowers that barrier by allowing displays to be powered using low-voltage Ethernet cabling, reducing installation time and safety constraints. Reducing separate power infrastructure also minimises potential failure points in environments where dust, vibration and moisture are constant challenges.
Michael Gribbons, Founder, President and CEO of Maestro Digital Mine, said: “Extending electrical power in underground mining environments introduces cost, risk and operational disruption. By using Power over Ethernet, the SuperBrite Marquee Display removes the need to treat signage as a special electrical project. It becomes a standard, managed network device, delivering trusted information reliably without introducing additional electrical complexity underground.”
Designed for continuous 24/7 operation in harsh underground environments, the SuperBrite Marquee Display provides high-visibility LED readouts of real-time environmental and ventilation data, including airflow, gas concentrations, humidity and temperature. As part of the Maestro Digital Mine ecosystem, the display integrates directly with Vigilante AQS
and Zephyr AQS air quality monitoring stations, delivering live data over a managed PoE network rather than relying on locally maintained systems. Centralised power and network management allow operators to monitor device status, reset displays remotely, and ensure information remains current and visible underground, Maestro says.
Built-in fail-safe behaviour alerts crews if communication is lost, preventing outdated information from being relied upon. When powered through PoE switches with backup power, displays can also maintain predictable operation during brief outages, supporting more consistent information delivery in safety-critical environments.
By eliminating the requirement for dedicated electrical infrastructure at each display, the PoE-enabled SuperBrite Marquee Display also makes it easier to add, replace or relocate signage as underground networks expand – without triggering additional electrical work or re-certification.
