A ‘No’ response returns to the deployment menu for further parameter entry. This
feature can be used to quickly loop through the range and consistency checks and the endurance
calculation while making iterative adjustments to the deployment parameters. This loop can be a
useful tool when developing profiling schedules for a deployment.
A ‘Yes’ response stores the deployment definition parameters in the EEPROM and then
runs a single iteration of Diagnostics, the Main Menu utility that scrolls status information.
Diagnostics includes the 10 V and 7.5 V battery warning checks (a warning message displays if
more than ~90% of the energy in the battery has been used).
Committing to the Deployment
The final deployment prompt is ‘Proceed with the deployment (Yes/No) [N]?’ Two
separate keystrokes are required, making an accidental deployment unlikely.
IMPORTANT
Before a deployment, archive a copy of the data files stored on the flash card. Once the
firmware is initialized for use, the flash card is reformatted, erasing stored data files.
Once ‘Proceed with Deployment’ is ‘Yes’ the firmware enters LPS for the programmed
interval so that the MMP can be deployed in the water. The firmware ‘wakes’ at the specified
schedule start time and performs Profile 0 (Dive 0), taking the MMP to the bottom of the
programmed range. Subsequent profiles are numbered sequentially, and follow the programmed
schedule. The sensors power on two minutes before the scheduled start time of each profile, log
data autonomously during the profile, and the MMP records engineering and status information.
Odd numbered profiles proceed from the bottom to the top of the programmed range.
Even numbered profiles proceed from top to bottom.
Profiling stops when the end of the programmed profiling range is detected. The sensors
continue to log internally for two minutes, stop, and transfer data to the flash card. A profile is
complete when the sensor and engineering files have been closed. The firmware enters LPS and
waits for the next scheduled profile. The MMP continues to profile until the deployment is
terminated.
