What is DiveCAN
®
?
DiveCAN
®
is a digital communications standard developed specifically for rebreathers.
DiveCAN
®
connections allow rebreather components to communicate
A minimum configuration has a
Control Bus
with a handset connected to rebreather electronics
("bus" is a term used to describe the connections between communicating electronic modules)�
Depending on your rebreather, a secondary
Monitor Bus
may be used� This independent bus
provides backup PPO2 monitoring in the event of a failure of the primary control bus�
Spare auxiliary ports may be included for additional devices or future expansion� Even if your
rebreather does not have a spare port, additional devices can be added with the use of Y-cables�
DiveCAN
®
devices connect together using specially designed underwater connectors� This allows
easy disconnection of devices for upgrades, repair, and travel�
