Software updates
New software releases will be made available via the Ocean Instruments website. You may which to
subscribe to our email list in order to receive notification of these updates. The update procedure is
generally straightforward
–
simply install the new software over top of the existing by running the
msi file and following the usual Windows software install prompts.
The software updates will typically include updates to both the windows software as well as the
device firmware. The updating of the device firmware is an automatic process that occurs when
pressing the ‘deploy’ button.

MSP firmware updates
From time to time a software release may include an update to the ‘MSP’ fi
rmware. This is a special
section of the device firmware that changes infrequently. In the rare event that an MSP update is
required, the user will be advised during the deploy procedure and will be asked to connect the
‘reset battery’. This is a security
feature that ensures the MSP firmware cannot be unintentionally
modified. In order to proceed you will need a 9V battery. When asked to ‘connect the reset battery’
you should connect the 9V battery to the battery connector provided on the USB cable.
Note that
you must make this connection in one smooth motion, being careful not to ‘bounce’ the
connections between the battery and the contacts
. Once the connection is made you can click the
OK button as per the software instructions. You will then be asked to remove the reset battery. This
done, the MSP firmware update will proceed and complete within a few seconds. If presented with
the error message “MSP Erase failed”, it is likely that the connection of the battery was not smooth –
please try again, this time ensuing that the contacts come together in a smooth motion, without
bouncing.

Calibration
Each SoundTrap is factory calibrated from new. The standard factory calibration consists of a piston
phone calibration at 250 Hz, performed for both low and high gain settings. The calibration data is
not shipped with the hydrophone, but instead made available online from the calibration page of
the Ocean Instruments website
http://www.oceaninstruments.co.nz/
The calibration data is provided as an end-to-end value. This measure is provided for both high and
low gain settings, and represents the SPL that will result in a normalised (±1.0) wav file with a full-
scale signal ie 2.0 units peak to peak.
