OPERATION
MASTER UNIT OPERATION
Master units operate on a repeating 68-minute cycle. In each cycle, the Master unit will read its own cables,
communicate with each Remote unit, and call-in to the Bin-Sense servers. When not performing one of these
tasks, the Master unit will go into a low power sleep mode to preserve battery life.
Master units communicate with Remote units one at a time and communicate with Remote units in the same
order every cycle.
REMOTE UNIT OPERATION
When a Remote unit is first powered on, it will read the attached cables, then perform the diagnostic LED
blinking pattern and listen for a wireless signal from a Master unit. This uses a large amount of battery power if
solar power is not available, so it is best to minimize the amount of time that the Remote unit is powered on and
not connected to a Master unit.
Once a Remote unit has communicated with a Master unit, it will enter a low-power sleep state to preserve
battery life. After 68 minutes, the Remote unit will wake up and send sensor cable readings to the Master unit.
This cycle repeats every 68 minutes.
If a Remote unit is unable to communicate with the Master unit for six consecutive cycles, it will start the LED
blinking pattern again and listen for Master units.
MASTER UNIT MODES
When a Master unit is powered up, it can enter normal mode or listener mode depending on whether there are
Remote units associated.
NORMAL MODE
When starting up in normal mode, the Master unit will read the attached cables, perform the diagnostic LED
blinking pattern, and then start the normal operating cycle by communicating with Remote units.
