The Sonar IP Address and Subnet Mask should be in
the same range as the Computer IP Address and Subnet
settings. To program a different Sonar IP Address and/or
Subnet Mask into the selected Gemini Sonar, change the
values in this panel and then click 'OK' on the main form
to upload these changes into the Sonar.
Set to 'Auto' to apply the in-built velocimeter speed of sound
calculation to the sonar data. Set to 'Manual' to revert to a fixed
speed of sound. This fixed speed of sound is the manual V.O.S.
(Velocity Of Sound) setting configured in the Environment dialog
from within Seanet Pro.
The two modes of operation are Triggered and Continuous.
In Triggered mode the Gemini will be sent continual triggers
where one trigger will instruct the Gemini to ping once. Each time
Seanet receives data for the current scan, it will respond and send
the next trigger to the Gemini to instruct it to perform the next ping.
This turnaround is half duplex in nature. In Continuous mode,
Seanet Pro sends one command at start-up which instructs the
Gemini Sonar to ping continuously. For both modes an inter-ping
time delay is also sent to the Sonar to control the scan update rate.
This InterPing Period is set in the Setup dialog accessed
through the Tools menu in Seanet Pro.
