Seakeeper 2 Operation Manual (90489-3); S/N 2-232-1564 to Current
3.1 ConnectBox and Display Screens: Overview
Introduction
The Seakeeper 2 requires the ConnectBox and connection to either, preferably, a compatible MFD or a Seakeeper 5” Touch Display. The compatible MFD and Seakeeper 5” Touch Display will show the same Seakeeper Application outlined in this section.
When 12 VDC power is applied to the Seakeeper, the ConnectBox will illuminate and the Seakeeper Application on the 5” Touch Display and/or MFD will initialize. If connecting the ConnectBox to an MFD, and the Seakeeper App does not appear on the MFD, please refer to appropriate Technical Bulletin to troubleshoot, at www.seakeeper.com/technical-library/ and filter for the Seakeeper 2:
- TB-90478 – Garmin and Seakeeper Compatibility
- TB-90479 – Raymarine and Seakeeper Compatibility
- TB-90480 – NAVICO (Simrad/Lowrance/B&G) and Seakeeper Compatibility
- TB-90598 – Furuno and Seakeeper Compatibility
ConnectBox Overview
- The ConnectBox POWER button will pulse red if the Seakeeper causes an alarm. The alarm must be addressed on the Seakeeper Application.
- The BRIGHTNESS button
on the ConnectBox will toggle through different different brightness settings of the ConnectBox LED brightness. - The ETHERNET button
on the ConnectBox allows integration with Multifunction Displays (MFD). Pressing the button for several seconds will show the ConnectBox synchronization mode by strobing progress bar left or right. The progress bar is beneath the brightness and ethernet buttons. See applicable MFD and Seakeeper Compatibility technical bulletin for further information.
ConnectBox and Home Screen
- After the Seakeeper ConnectBox and Application have initialized, the ConnectBox and Application Home Screen will be displayed as shown below.
- The Seakeeper can be controlled by either the ConnectBox (shown in images on left) or the Application on the Seakeeper 5” Touch Display or compatible MFD (shown in images on right). Seakeeper POWER button: when pressed, the button will change from grey (Seakeeper Off) to blue (Seakeeper On).
- Seakeeper STABILIZE button: when pressed, the button will change from grey (Stabilize Off) to blue (Stabilize On).
- On the MFD or 5″ Touch Display Application Home Screen view, these buttons can be pressed to toggle Home Screen views between the Roll Angle Gauge and the Roll Angle Graph as shown below.
- When the MENU button is pressed,
the Menu Bar will appear or disappear at the bottom of the screen.
- The Menu Bar is used to navigate between pages. From left to right, the available pages are Home, Settings, Information, Service, and Alarm History. The selected page is highlighted in blue on the Menu Bar.
Settings Page
- The Settings Page allows the user to adjust their preferences for the Seakeeper and its display. It can be accessed by pressing the gears
in the menu bar.
- The language on the Seakeeper Application can be changed using the Settings Page. By clicking ENGLISH, a dropdown appears, and the desired language can be selected.
- On the Seakeeper 5” Touch Display only, there is a sleep timer. Adjust the sleep timer from 1 minute to infinite using sleep time slider. Touching the screen will wake the display up after it has gone to sleep. The MFD should be controlled within the MFD’s settings.
- If the Seakeeper is facing the bow of the vessel, the Roll Angle Gauge should show the blue on the left (pictured left). If the Seakeeper is facing the stern of the vessel, one should select the Roll Angle Gauge with the blue on the right (pictured right). A positive roll angle should be displayed when the vessel rolls to starboard.
- Change the speed of the Seakeeper between normal operation and low power operation. Low power mode consumes less power and should generate less noise. The selected speed is colored blue. When power is cycled (or Seakeeper turned Off), this speed will default back to the normal operating speed.
- Change the display between day and night mode. The selected mode is colored blue and to change between day and night mode, press the button.
- Change the units of the temperatures displayed on the Service Page between degrees Celsius and degrees Fahrenheit. The selected units are colored blue.

Battery State of Charge Monitoring
Traditional batteries have a near-linear discharge voltage curve; new Lithium batteries do not have the same voltage curve. This characteristic makes it difficult to determine the Lithium battery charge state. Seakeepers have used battery voltage depletion to initiate power ramp-downs to extend battery life. With Lithium batteries, battery voltage is no longer an accurate indicator for this function; the state of charge (SoC) NMEA 2000 signal is more accurate when available.
Seakeeper software uses the NMEA 2000 State of Charge (SoC) signal to initiate a power ramp-down when an NMEA 2000 SoC signal is available on the network—the following guides in setting the Battery Monitoring Logic of the Seakeeper.
- Access battery monitoring configuration by one of the following methods:
- Press and hold battery icon on home screen until configuration manager pop-up appears.
- From SoC alert pop-up , press CONTINUE.
- On Battery Monitoring Configuration window, select the appropriate selection from the dropdown menu:
- No Selection – This is the default setting for the configuration manager.
- Disabled – Use voltage monitoring: This disables SoC logic and uses actual battery voltage to initiate powering back of the Seakeeper when battery voltage is low.
NOTE: If Seakeeper is NOT supplied by lithium batteries, this option should be selected. - Battery SoC from 0xE0 – This option allows the user interface to monitor the NMEA 2000 network for the battery state of charge from a battery management system monitoring the Seakeeper battery bank. (recommended if lithium batteries are used to power the Seakeeper).
When selected, the Cut-off threshold slider will determine at what battery charge the Seakeeper begins powering back to conserve battery power. Also, the 5” Touch Display will show battery state of charge in 20% increments beside the battery icon on the home screen (instead of a voltage). - Battery SoC from 0xE4, etc. – Lists all source addresses from which the NMEA SoC signal is received (Multiple battery management systems may exist; select only the battery monitor attached to the Seakeeper battery bank).
