Connecting Oxygen Sensors

How to connect the oxygen sensors to different electronic systems

Most redundant systems in case off: (all offering redundancy on at least one sensor level)

3 cells / 2 electronic systems

• 2 rEvodreams: 2 sensors on dream 1 / 1 sensor on dream 2
• 1 rEvodream + 1 Shearwater: 2 sensors on dream / 1 sensor on SH

3 cells / 3 electronic systems

• 2 rEvodreams + 1 Shearwater: each system reading 1 sensor
• 1 rEvodream + 2 Shearwaters: each system reading 1 sensor

4 cells / 2 electronic systems

• 2 rEvodreams: each rEvodream reading 2 sensors
• 1 rEvodream + 1 Shearwater: 1 sensor on rEvodream / 3 Sensors on SH

4 cells / 3 electronic systems

• 2 rEvodreams + 1 Shearwater: 2 sensors on one deam, other systems 1 sensor
• 1 rEvodream + 2 Shearwaters: 2 sensors on dream, other systems 1 sensor

5 cells / 2 electronic systems

• 1 rEvodream + 1 Shearwater: 2 sensors on dream / 3 sensors on SH

5 cells / 3 electronic systems

• 2 rEvodreams + 1 Shearwater: 3 sensors on SH, one on each rEvodream
• 1 rEvodream + 2 Shearwaters: 3 sensors on SH1, one on each other system

Alternative systems also used but less redundant:

4 cells / 2 electronic systems

• 1 rEvodream + 1 Shearwater: 2 sensors on rEvodream / 3 sensors on SH, so splitting 1 sensor

4 cells / 3 electronic systems

• 2 rEvodreams + 1 Shearwater: 3 sensors on Shearwater, of those 2 are split to one rEvodream, second rEvodream on 1 sensor only (using 2 splitters)

5 cells / 3 electronic systems

• 2 rEvodreams + 1 Shearwater: 3 sensors on Shearwater, of those 2 are split to one rEvodream, second rEvodream reads 2 sensors (using 2 splitters)
