Simrad ST90 Technical specifications
To choose the best power solution for your installation, consider environmental
conditions, the physical space available, the availability and duration of the batteries, and
the power requirements of the ST90 system.
Operating Panel option
The optional Operating Panel contains all necessary control functions for normal
operation of the ST90 system.
The controls provided by the Operating Panel are arranged in logical functional groups.
This offers you clear and easy operation with fast access to key functionality. All the
functionality provided by the ST90 system can be accessed using the trackball on the
Operating Panel and the menu system shown in the display presentation.
The ST90 system supports three different operating panels. These are referred to as
"Mk1", "Mk2" and "Mk3".
• The Mk1 Operating Panel is connected to the Processor Unit with three cables. The
dual interface cable provides power and serial communication. The USB interface
cable is used to read the trackball movements. The Processor Unit must be fitted with
a custom made interface board. A small commercial power supply is used to provide
power to the Operating Panel. (The Mk1 Operating Panel is no longer provided with
new sonars. This information is provided for legacy reasons.)
• The Mk2 Operating Panel is connected to the Processor Unit using an Ethernet cable.
The Operating Panel is provided with a built-in power supply.
• The Mk3 Operating Panel is connected to the Processor Unit with a USB cable. A
dedicated power supply unit is not required.
Global positioning system (GPS) option
A global positioning system (GPS) may be connected to the ST90 system.
When a global positioning system (GPS) connected to the ST90 system, the vessel's
current geographical position can be presented in the user interface. It will also
provide latitude and longitude information for the cursor and marker(s). In addition to
navigational data, the global positioning system (GPS) can also be used to provide
speed information.
Note
Most global positioning system (GPS) can provide course information, but this data is
generally too inconsistent to provide a stable presentation on the ST90 system. This
inconsistency is especially noticeable at low vessel speeds. Incorrect course information
can then result in settings not working properly.
