Modular design compartmentalizes critical functions for redundancy. The Solenoid and
Oxygen electronics (on the SOLO board) can measure and inject oxygen independently of
the Primary handset even in case that the handset or its cable is unplugged or damaged.,
while the SOLO board continues to control loop PPO2 until the diver is surfacing.
The control electronics uses the DiveCAN®, a digital communication standard developed
by Shearwater Research Inc. specifically for rebreathers for robust error-checked
communications, when a message is either received correctly or it isn’t.
The DiveCAN® is easily upgradable and expandable.
PPO2 reading output from all the three oxygen sensors are electronically separated one
from another as well as the PPO2 reading outputs to the Primary Controller, Head-Up
Display and the secondary computer are electronically separated one from another.
In the event of a failure or short circuit on any sensor or connected device, it does not
affect the remaining ppO2 readings on a working device.
The secondary Monitoring Bus is independent on the Controller Bus and provides backup
PPO2 monitoring in the event of a failure on the Primary Controller. There is as well the
possibility of connecting a third party analog monitoring computer.
