S-Link System Description
S-Link is a CAN-based control system used for communication between Sleipner products installed on a vessel. The system uses BACKBONE Cables
as a common power and communication bus with separate SPUR Cables to each connected unit. Units with low power consumption are powered
directly from the S-Link bus therefore one power cable must be connected to the BACKBONE Cable through a T-Connector. The S-Link cables should
be installed such that sharp bend radius is avoided. Locking mechanism of connectors must be fully closed. Cables, T-Connectors and Extenders
should not be located such that they are permanently immersed in water or other fluids.
Main advantages of S-Link system:
- Compact and waterproof plugs.
- BACKBONE and SPUR Cables have different colour coding and keying to ensure correct and easy installation. BACKBONE Cables have blue
connectors and SPUR Cables have green connectors.
- Different cable lengths and BACKBONE Extenders makes the system scalable and flexible to install.
Installation of S-Link cables:
Select appropriate cables to keep the length of BACKBONE- and SPUR Cables to a minimum.
The S-Link cables should be installed to ensure sharp bend radius’s is avoided. The locking mechanism on connectors must be fully closed. Cables,
T-Connectors and Extenders should not be located so that they are permanently immersed in water or other fluids.
The POWER Cable should ideally be connected around the middle of the BACKBONE Cable to ensure an equal voltage drop at each end of the
BACKBONE Cable. The yellow and black wire in the POWER Cable shall be connected to GND and the red wire connected to +12VDC or +24VDC.
To reduce the risk of interference, avoid routing the S-Link cables close to equipment such as radio transmitters, antennas or high voltage cables. The
backbone must be terminated at each end with the END Terminator.
Spur cables can be left unterminated to prepare for the installation of future additional equipment. In such cases, ensure to protect open connectors
from water and moisture to avoid corrosion in the connectors.

SPUR Cable
Used to connect S-Link compliant products to the
backbone cable. One SPUR Cable must be used for
each connected component, with no exceptions.
Recommended to be as short as practically possible.
Available in different standard lengths.
POWER Cable
Must be one in each system. Connects BACKBONE Cable
to the power supply.
4-Port T-Connector
The 4-PORT T-connector allows multiple SPUR Cables to be
connected. The 4-PORT T-connector comes with two sealing
caps to protect unused ports.
T-Connector
Used for connection of SPUR
or POWER Cable to the
BACKBONE Cable. One
T-Connector for each
connected cable.
BACKBONE Extender
Connects two BACKBONE
Cables to extend the length.
END Terminator
Must be one at each end of
the BACKBONE bus.
