CAN Interface (NMEA 2000)

Connection

GW-1 is an NMEA2000 certified device. Connect an S-Link spur cable to the S-Link backbone and the NMEA 2000 equipment to the M12 male CAN INTERFACE connector.
Use for engine system, GNSS antenna, joystick controls, DP-system and autopilot integration; do not connect it to other networks (interference or crashes).
GW-1 does not power the CAN bus and has no termination resistor on the M12 output: the CAN bus needs its own power feed and terminators. CAN-L and CAN-H are galvanically isolated.
Use standard NMEA 2000 micro cable (not supplied by Sleipner).
M12 pinout: pin 1 NC, pin 2 NC, pin 3 GND, pin 4 CAN-H, pin 5 CAN-L.
TX / RX LEDs flash (max 100ms on / 100ms off) when sending / receiving.

NMEA 0183 GPS Input

V OUT can power a single GPS antenna, max 100mA, internally fused; V OUT is S-Link bus voltage. RX A(+) and TX B(-) are galvanically isolated.
4800 and 38400 baud are supported and set automatically; $GxRMC sentences from all positioning systems are supported.
NMEA 0183 LED: off = no valid GPS signal; flashes 100ms/100ms for a valid message at 38400 baud, 100ms/900ms at 4800 baud.
GNSS priority: 1) NMEA0183 at 100ms update rate, 2) NMEA2000, 3) NMEA0183 at 1000ms. Only one NMEA 2000 antenna is forwarded, and with several GW-1 only one broadcasts GNSS on S-Link (requires GW-1 firmware V1.021 or newer).
Status LED: off = no power; on = S-Link communication and power OK; flashing 500ms/500ms = power OK but no S-Link communication.

Installing the GW-1

Fasten the GW-1 box to a solid surface with four mounting screws.
Attach the required cables: S-Link spur, NMEA 2000 and/or NMEA 0183. No external power is needed – GW-1 is powered from S-Link.

Any direct connection to S-Link without an approved Sleipner interface voids the warranty of the connected Sleipner products.

S-Link System Rules

Cables & Connectors

Component	Role
BACKBONE Cable (blue ends)	Common power and communication bus through the vessel; standard lengths
SPUR Cable (green ends)	One per connected product, no exceptions; keep as short as practical
POWER Cable	Required in every installation; only one per BACKBONE; protect with a 2A fuse. Yellow and black wires to GND, red to +12VDC or +24VDC
T-Connector	One per SPUR or POWER Cable on the BACKBONE
4-Port T-Connector	Several SPUR Cables on one point; two sealing caps for unused ports
BACKBONE Extender	Joins two BACKBONE Cables
END Terminator	One at each end of the BACKBONE bus

Installation Rules

Keep BACKBONE and SPUR lengths to a minimum; consult your distributor if the total BACKBONE exceeds 100 meters.
Fasten cables to avoid sharp bends, chafe and strain on connectors; close the connector locks fully.
Do not leave cables, T-Connectors or Extenders permanently immersed; make a U-bend before each product connector so water does not run into it.
Ideally connect the POWER Cable in the middle of the BACKBONE for equal voltage drop at both ends.
Route S-Link away from radio transmitters, antennas and high voltage cables.
Unused SPUR cables may be left unterminated for future equipment: protect the open connectors from water.
Connect only original Sleipner S-Link products or authorised equipment directly to the bus; third-party equipment goes through a Sleipner interface, and at least one original Sleipner control panel must still be installed.
