Multi Board, Lighting & Control System Components

PMMI Lighting Controller

Max 1 per Multi-Board Lighting & Control System • located in The Control Center

The PMMI Lighting Controller, Arduino Mega Controller, is the “brains” of the system and provides real-time monitoring of switches, motion sensors, and timed events, and subsequent control of the lighting system. The Controller is completely dedicated to real-time functions in order to ensure high reliability, responsive, and smooth (no flicker) lighting-control performance.

The Arduino Mega is a single-board computer available from Arduino and many third-party suppliers. Millions are in service in professional and do-it-yourself applications across the globe. The Arduino is a premier platform, used in electronics and computer engineering education programs worldwide. Click here for more information on the Arduino Mega 2560.


PMMI Lighting HUB

Max 1 per Multi-Board Lighting & Control System • located in The Control Center

The PMMI Lighting HUB, featuring the Raspberry Pi 3 Model B+ is a single-board computer running the Raspbean Linux operating system. The Raspberry Pi provides:

  • Internet Connectivity (WiFi and Ethernet)
  • Graphical User Interface for PMMI support
  • Real-time server for Arduino controller (e.g. time and configuration updates, remote control)
  • Installation-specific configuration hosting

The Raspberry Pi is an open-source computing platform available from multiple vendors and broadly used worldwide by product manufacturers, educators, and do-it-yourselfers. Click here for more information on the Raspberry Pi.


Driver Board, 16 outputs

Max 10 per Multi-Board Lighting & Control System • located in The Control Center

PMMI Lighting light fixtures are driverless, they do not have on-board drivers. Instead, drivers are hosted on Driver Boards. Separating the driver from the fixture allows the electronics to operate at lower temperatures thus extending life expectancy. Eliminating the driver from the fixture also reduces fixture cost.

Each Driver Board can accommodate up to 16 LED light strings or “channels”, each comprised of up to 8 – 6 watt fixtures connected in a daisy chain manner using Cat5/6 cable.

Each channel has a constant-current driver. Driver output current, and thus luminaire intensity, is controlled through a PWM input signal delivered by an on-board 12-bit PWM controller providing high-fidelity lighting control.

PWM control is regulated between zero and 100 percent. This results in constant current output from zero to the driver’s rated current. In this example, 1 Amp (1000ma) drivers are used. In the event that the physical area illuminated by the channel is too bright, it’s possible to lower the maximum intensity by swapping out the driver module for 300, 500, 700, and 1000ma drivers. It is also possible to set the max light percentage output by specifying it in the configuration software under the channel tab without changing out the drivers.


Switch Reader Board, 8 inputs

Max 6 per Multi-Board Lighting & Control System • located in The Control Center

Switch Reader Boards can accommodate up to eight switch strings each. Each are comprised of up to seven individual buttons/functions and connected in a daisy chain manner using Cat5, Cat5e or Cat6 cable.


Motion Reader Board, 16 inputs

Max 2 per Multi-Board Lighting & Control System • located in The Control Center

Motion Reader Boards can accommodate up to sixteen PMMI Lighting motion sensors – for a total of 32 if you max out the system (2 boards max). Sensors are connected using Cat5/6 cable.


Daylight Harvesting Reader Board, 14 inputs

Max 1 per Multi-Board Lighting & Control System • located in The Control Center

The Daylight Harvesting Reader Board can accommodate up to 14 PMMI Lighting, daylight harvesting sensors. Sensors are connected using Cat5/6 cable.
