Seakeeper 10 Installation Manual (90841-1)
3.4 ConnectBox Connections
Seakeeper 10 Display Options
A compatible display is required with the installation of a Seakeeper 10 to support the full functionality of the unit through the Seakeeper App in addition to the ConnectBox. The Seakeeper App provides an interface for controlling the Seakeeper 10 or viewing the Settings, Service, Info, and Alarm pages. The Seakeeper ConnectBox can be helm-mounted to provide an additional interface for the control of the Seakeeper 10 but does not replace the need for a Seakeeper compatible display.
The Seakeeper 10 has several control interface connection options to support the Seakeeper App:
- Connect the Seakeeper 10 to a compatible Multifunction Display (MFD) as seen in Figure 26.
- Install an optional Seakeeper 5″ Touch Display (P/N 90467) as seen in Figure 27.
- A combination of a compatible MFD and an optional 5″ Touch Display.
The following figures provide schematics of display options. The subsequent sections outline the instructions and references for connecting the Seakeeper 10 to a compatible MFD display or an optional Seakeeper 5″ Touch Display.


Connecting to a Compatible MFD
- The Seakeeper 10 can be connected to various available MFD systems. For manufacturer-specific MFD compatibility technical bulletins, refer to the Technical Bulletins Section of the Seakeeper Technical Library.
- MFD specific Technical Bulletins will be updated regularly as new MFD systems become available. Currently Garmin, Raymarine, NAVICO (Simrad, Lowrance, B&G), and Furuno offer compatible MFD models.
- Once a compatible MFD has been selected, refer to the appropriate manufacturer specific Technical Bulletin for integration instructions.
- Connect Seakeeper-supplied Ethernet Adapter cable, M12 D-Code, 82 ft (25 m), cable to MFD manufacturer-specific Ethernet adapter cable (See Figure 26 above). Custom Ethernet cables for specific MFD manufacturers are available through Seakeeper and must be purchased with the Seakeeper 10 when connecting to an MFD.
Connecting to an Optional Seakeeper 5″ Touch Display
If not utilizing a compatible MFD display, a Seakeeper 5” Touch Display must be purchased from Seakeeper. The Seakeeper 5” Touch Display (P/N 90467) includes the components shown in the following figure and will be integrated with the ConnectBox.

(P/N 90467-2SP-XXM)
- Determine the location of Seakeeper 5” Touch Display:
- The desired location of the 5” Touch Display must be determined for the vessel’s arrangement.
- The 5” Touch Display should be located on or near the helm or another easily accessible location.
- Route NMEA CAN communications cable:
- The CAN Cable, (labelled NMEA Cable in Figure 28), is a 25 m shielded cable that connects the ConnectBox Tee adapter to the 5” Touch Display.
- Additional lengths are available: 10 m, 35 m, 50 m, and 65 m.
- The 82 ft (25 m) NMEA CAN cable must be routed and installed in the vessel from the Seakeeper 10 wire harness CAN Tee to the Tee Adapter at the Seakeeper 5” Touch Display, included with P/N 90467.
- The CAN Cable, (labelled NMEA Cable in Figure 28), is a 25 m shielded cable that connects the ConnectBox Tee adapter to the 5” Touch Display.
- Install Seakeeper 5″ Touch Display equipment:
- Console space required: Approx. 5.24 W x 3.70 H in. (133 x 94 mm)
- Mounting Instructions, Surface Mount: see Envelope and Mounting Details, in Drawing No. 90438 – 5” Display Envelope and Mounting Details.
- CAN communications tee adapter and terminator mounting instructions:
- Console space required, Rear: Approx. 4 W x 3 H in. (102 x 76 mm)
- Mounting Instructions: Rear mount on vessel console panel, within 2 ft (0.6 m) of Display.
- Hardware required: One mounting screw for a .197 in. (5 mm) diameter mounting hole on Tee Adapter.
- Connect Seakeeper 5” Touch Display Equipment:
- The Seakeeper 5” Touch Display is connected per Figure 27 above.
- The USB Extension Cable is 6.5 ft (2 m) long cable that enables software updating on a 5″ Touch Display where accessibility to rear panel is limited.
NMEA 2000 Network Connection
The Seakeeper 10 requires a connection to the vessel’s NMEA 2000 network backbone via a drop cable to access the GPS signal. The Seakeeper 10 monitors information on the NMEA network to support and optimize its performance. If no GPS signal is detected, a warning will appear on the Seakeeper display. The Seakeeper will not spool down, but the unit’s operation will be limited until the GPS signal returns.
- Install customer-supplied NMEA 2000 Tee Adapter (space required: approximately 4 W X 3 H in. (102 X 76 mm).
- Connect NMEA Backbone to Tee Adapter. NOTE: NMEA drop cable can be no longer than 19.6 ft (6 m) in length.
- ConnectBox can be remote mounted at a location closer to the NMEA backbone when the 6 m drop cable length is insufficient. See ConnectBox Helm Mounting instructions below.
- Connect Seakeeper-supplied NMEA cable (P/N: 30332) to the customer-supplied NMEA 2000 Tee Adapter on vessel’s NMEA 2000 backbone.
- An active NMEA 2000 compatible GPS signal is required on the vessel’s NMEA 2000 backbone to operate the Seakeeper 10.
- If no GPS signal is detected, the Seakeeper app will display a Speed Over Ground (SoG signal) warning. For NMEA connectivity guidance, see TB-90640.
- An active NMEA 2000 compatible GPS signal is required on the vessel’s NMEA 2000 backbone to operate the Seakeeper 10.
ConnectBox Helm Mounting – Optional
- Console space required: Approx. 3.41 L x 4.15 W in. (87 x 106 mm).
- Mounting Instructions, Surface Mount: See Drawing No. 90558 – Seakeeper ConnectBox Helm Mounting Kit, for details. Seakeeper ConnectBox 3D Model available upon request.
- Mount ConnectBox Replacement Blank insert into Seakeeper 10 enclosure at the original location of the ConnectBox.
