Focus Technologies:
Maestro- Plexus PowerNet™
Product Type: Network device
The Plexus PowerNet system allow mines to connect the last mile worker at the face. Plexus PowerNet™ delivers a high speed, low latency digital communication network that provides PoE+ power to Access Points (APs), cameras and other IP based devices.
The system eliminates the need for costly outside fibre optic contractors and can be installed and maintained by any internal tradesperson. The single coaxial cable system that carries both power and network communication allows easy and fast installation and rugged cable to withstand underground conditions.
Capabilities:
- Power: Easy to add DC power at any Node. A single power supply will power 8-10 Access Points (APs) reducing total infrastructure cost and time.
- Connect: Easy to connect directly to a level network switch. Combine power and network connectivity onto a single cable. Each node provides a 4 port PoE+ network switch in fully managed or unmanaged mode.
- Advance: Easy to add splitters and additional nodes. Easy to install, extend, terminate and maintain by in-house electrical trades or development miners.
- Repair: No skilled labour required to troubleshoot or replace components, saving time and increasing production rates
Plexus PowerNet in mining:
- Deliver internet to underground Access Points (APs) allowing IOT to connect to the internet (Realwear device) for remote expert assistances
- Connect PLCs
- Access data from Air quality stations on the surface



Maestro – Vigilante AQS™
Product Type: Air Quality Station
The world’s first total air quality monitoring station that measures multiple gas concentrations, airflow, wet bulb and dry bulb temperature and atmospheric pressure with a single digital IP connection. It has a modular design that makes it very flexible, and it can be integrated into any SCADA, PLC, DCS, PLS or HMI system. Whether it is Modbus TCP/IP, EtherNet/IP or RS485 serial based, the Vigilante AQS™ does it with grace and efficiency.
Capabilities:
- Modular design provides ultimate user flexibility.
- Make informed ventilation decisions with real-time data.
- Save time with Maestro EZ Upgrades
- Easy as PI – integration into historians
- Direct integration with Ventsim™ CONTROL
- Improve your mine ventilation simulation models
- EZ Cal gas sensors increase sensor reliability and accuracy



Maestro – Zephyr AQS™
Product Type: Air Quality Station
Zephyr AQS™ is an ultra-compact, low cost environmental air quality monitoring station for underground mines. This Industrial Internet of Things (IIoT) device connects directly to any network without the requirement of adding an expensive and complex programmable logic controller (PLC).
The Zephyr AQS™ air quality station features three fully customer configurable plug and play sensor inputs that can be freely mixed and matched according to the underground requirements. Configuration is done through built-in webpages similar to that of a home network router. All sensors that connect to the Zephyr AQS™ utilize industry standard digital protocols.
The Zephyr AQS™ fully supports the two most popular network communication protocols – Modbus TCP/IP and EtherNet/IP™. Alternately, the Zephyr AQS™ offers optional on-board analogue outputs (3 x 4-20 mA) and/or two relay outputs that can tie into any legacy system.
Capabilities:
- Modular design provides ultimate user flexibility
- Make informed ventilation decisions with real time data
- Save time with Maestro EZ Upgrades
- Easy as PI – integration into historians
- Direct integration in Ventsim™ LiveVIEW and VUMA3D ventilation modelling software
- Improve your mine ventilation simulation models
- EZ Cal gas sensors increase sensor reliability and accuracy
