Use icons on the main menu

Select this function to use icons instead of text on the Main menu.

Menu on the Right Side

Select this option to place the menu system on the right side of the display presentation. This is the default setting. By deselecting this function, the entire menu system is placed permanently on the left side of the display presentation.

Top Bar

The top bar is located at the top of the display presentation and stretches from the far left to the far right. By means of these check boxes, you can select which elements to be shown at the top of the presentation.

For each option, the text in brackets is the identification used on the top bar.

Navigation

Select this check box to see the vessel’s current geographical position on the top bar. The position information must be provided by an external navigation system connected to the ST90 system.

Heading

Select this check box to see the vessel's current heading on the top bar. The heading information must be provided by an external positioning system, or by a heading sensor or gyro compass connected to the ST90 system.

You can set up datagram priorities for both heading and course information on the Sensor Configuration page. When enabled, the vessel's current heading is shown on the top bar. If the information from the heading sensor fails, the top bar will change to present the course information instead.

Speed

Select this check box to see the vessel's current speed on the top bar. The information must be provided by an external speed log or a navigation system connected to the ST90 system.

Bottom Depth

Select this check box to see the current water depth on the top bar. The information must be provided by an external depth sensor (echo sounder) connected to the ST90 system.

Roll

Select this check box to see the vessel's current roll movements on the top bar. The information must be provided by an external motion sensor (motion reference unit) connected to the ST90 system.

Pitch

Select this check box to see the vessel's current pitch movements on the top bar. The information must be provided by an external motion sensor (motion reference unit) connected to the ST90 system.

Temperature

Select this check box to see the current temperature on the top bar. The information must be provided by an external temperature sensor connected to the ST90 system.

Bottom Bar

UTC Time: Check the box to use Coordinated Universal Time (UTC). The time is shown on the bottom bar at the bottom of the display presentation. When disabled, the ST90 system uses local time.

Note:

To enable UTC time, your ST90 system must be set up to accept the NMEA ZDA datagram. The NMEA ZDA datagram contains the universal time code (UTC), day, month, year and local time zone.

Coordinated Universal Time (French: Temps Universel Coordonné, UTC) is the primary time standard by which the world regulates clocks and time. It is one of several closely related successors to Greenwich Mean Time (GMT). For most purposes, UTC is used interchangeably with GMT, but GMT is no longer precisely defined by the scientific community. [...]

The current version of UTC is defined by International Telecommunications Union Recommendation (ITU-R TF.460-6), Standard-frequency and time-signal emissions and is based on International Atomic Time (TAI) with leap seconds added at irregular intervals to compensate for the slowing of Earth's rotation. Leap seconds keep UTC within 0.9 seconds of universal time, UT1.
