Sonar, STW, and water temperature prioritization with Multiple Data Sources
Sonar, STW, and water temperature prioritization with Multiple Data Sources (LH3 R1 and onward)

DEPTH
With multiple depth sources, there is a ranking list based on sounder module:

1. CP570/CP470
2. Axiom Pro w/ Airmar CHIRP Ducer
3. CP370
4. Axiom Pro w/ Airmar 50/200kHz Ducer
5. CP450C
6. CP300
7. DSM300
8. DSM30
9. Axiom DV or RV w/ Airmar Ducer
10. MFD Embedded “7” Sounder
11. Axiom w/ RYM Ducer or Airmar 100W
12. CP100
13. MFD Embedded “8” Sounder
14. Axiom Pro w/ Raymarine Ducer


It is important to note that the visible presence of a bottom signal does not necessarily mean that the system recognizes that as bottom and therefore may pull the data from the next prioritized sonar source. To check this, simply turn on the “white line” overlay on the desired sonar application. If the white line is not present said sonar does not have a sufficient signal to classify it as bottom and the system will progress to the next prioritized sonar for a depth reading.

If there are multiple identical models (e.g. two networked CP100s), the highest serial number is preferred.

If there are no sonar modules with bottom readings, the system will then progress to alternative depth sources in the following order. The highest CAN address taking priority:

1. STng Instrumentation
2. MicroNet Instrumentation
3. ST1 Instrumentation
4. NMEA0183 Instrumentation


BOTTOM LOSS
If you lose bottom with your top prioritized sounder, and sonar from a lower prioritized sounder is being displayed within an open Fishfinder application page/pane within the system, and this other sonar has acquired bottom reading, then the Depth data box will populate with that secondary information.

If no fishfinder application page/panes are open within the system, then the system will go into “bottom finding mode” in which it uses the prioritization list above to ping the highest ranked sounder. It doesn’t try to locate bottom with a secondary sounder unless you open an app instance that includes a sonar of lower prioritization.

SPEED (STW- Speed through water)
With multiple speed sources, there is a ranking list based on network protocol (highest CAN address of similar protocols taking priority).

1. STng Instrumentation
2. MicroNet Instrumentation
3. ST1 Instrumentation
4. NMEA0183 Instrumentation
5. SThs Sonar Modules (highest serial number taking priority)


TEMPERATURE (water)
With multiple temperature sources, there is a ranking list based on network protocol (highest CAN address of similar protocols taking priority).

1. STng / NMEA 2000 Instrumentation
2. MicroNet Instrumentation
3. ST1 Instrumentation
4. NMEA0183 Instrumentation
5. SThs Sonar Modules (highest serial number taking priority)


Within LightHouse 3 software we have provided a means of deactivating temp sources, such that all non-desired sources can be removed from the network. The result is the user’s ability to select a single temp source for their system. Within the Fishfinder application, temperature thermistors may be blocked from use within the system via the command sequence SETTINGS->TRANSDUCER->ENABLE TEMPERATURE SENOR->OFF.
