Seanet Pro Operation
The Compass Settings dialog allows configuration of the compass and pitch/roll sensor
display on the main screen. The position can be selected only if Auto Positioning is first
de-selected. Also colour and opacity can be controlled through this dialog.
If more than one sensor is available for selection this should be performed in the
Installation dialog.
If an offset is required it can be entered here and the compass can be corrected for
displacement of magnetic against True North.

This sets the time delay between successive Sonar pings.
The 'Max Rate' will set the Sonar update rate to fastest
achievable (up to 15Hz). Range, plot size and PC CPU
specification will limit the maximum achievable rate.
Select the display range units. Options are Metres, Feet,
Fathoms, and Yards.
This indicates the current type of communications link
between the Gemini and surface. This can be either direct
Ethernet or VDSL.
This is the Uplink transmission speed for the active Link Type.
For Ethernet this will be either 10Mbit·s
VDSL this will be a rate that may be adapted according to
the VDSL Rate Adaption setting – for the 'Normal' setting, the
optimal Link Speed will be applied.
This indicates, respectively, the Number of Packets
transmitted from the Gemini, the Number of Dropped/lost
Packets and the Number of Packet Resends attempted.
This is the Number of Samples over the current Range scale.
If the Gemini Sonar is mounted upside down (that is the sonar
is positioned with the transmitter on the top rather than the
design orientation with the transmitter at the bottom), ticking
this box will flip the image from left to right, as viewed on
the computer screen, so that the image still appears correctly
oriented to the user.
This is used when the Gemini sonar is mounted with the
transducer pointing aft instead of forward
