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’ firmware. 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 ensure
s the MSP firmware cannot be unintentionally
modified. In the case of the ST500 the reset battery is replaced with a (somewhat hidden) reset
switch. This is located just above the top memory card slot. To press it you will need something long
and pointy, such as a small screw driver. The switch is operated by pressing toward the circuit
board.
When asked to ‘connect the reset battery’ you
must hold down the reset switch. Once the switch is
held down you can click the OK button (may require second person!) as per the software
instructions. You will then be asked to remove the reset battery (release the button). 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
pressing of the reset button was interrupted

Calibration
Two calibrations are associated with each ST500 system
–
the for the recorder, and that for the
hydrophone.
Recorder Calibration
Each ST500 recorder is factory calibrated to determine the electronic gain of the system. This
calibration process consists of inputting a tone of known signal level (in volts) and observing the
