  • 1 Safety Manual B000100
  • 1 Veratron Card  B000101


The resistive-type Link Up gateway provides an easy method to convert vessel and engine information to NMEA 2000®.
Compatible sensors are for example, but not only, liquid levels, temperature, or pressure senders.
Easily installed, the Link Up gateway replaces the original wiring, delivering power to both the Link Up device and sensor from the NMEA 2000® backbone while still being compliant with the NMEA 2000® certification requirements.
The data are then available for being displayed on any Ocean Link, Acqua Link, or more in general on any glass cockpit NMEA 2000® display device.
Configuring Link Up gateways is simple using a mobile device and the companion Link Up Configurator App for Android or iOS.
Each device has a built-in passive NFC antenna, so the parameters of the sensor are wirelessly configured to type, instance and warning threshold on the mobile device which is then “tapped” against the Link Up device for instant data download.


The Link Up gateway has a simple yet effective design. The potted housing allows the unit to be installed in engine rooms, making it compliant to the ISO 8846:1990 as requested by the directive 2013-53(EC).
The standard NMEA 2000® M12 plug allows for a plug-and-play installation to the network backbone.ؔ
The sensor connection happens though an AMP Super Seal plug, which perfectly matches the veratron level sensors, without the need of additional wiring.

  • Check all functions.
  • Use only clean water to clean the components. Note the Ingress Protection (IP) ratings (IEC 60529).


  • Note cable cross-sectional area!
  • Reducing the cable cross-sectional area leads to higher current density, which can cause the cable cross-sectional area in question to heat up!
  • When installing electrical cables, use the provided cable ducts and harnesses; however, do not run cables parallel to ignition cables or to cables that lead to large electricity consumers.
  • Fasten cables with cable ties or adhesive tape. Do not run cables over moving parts. Do not attach cables to the steering column!
  • Ensure that cables are not subject to tensile, compressive, or shearing forces.
  • If cables are run through drill holes, protect them using rubber sleeves or the like.
  • Use only one cable stripper to strip the cable. Adjust the stripper so that stranded wires are not damaged or separated.
  • Use only a soft soldering process or commercially available crimp connector to solder new cable connections!
  • Make crimp connections with cable crimping pliers only. Follow the safety instructions of the tool manufacturer.
  • Insulate exposed stranded wires to prevent short circuits.
  • Caution: Risk of short circuit if junctions are faulty or cables are damaged.
  • Short circuits in the vehicle network can cause fires, battery explosions and damages to other electronic systems. Consequently, all power supply cable connections must be provided with weldable connectors and be sufficiently insulated.
  • Ensure ground connections are sound.
  • Faulty connections can cause short circuits. Only connect cables according to the electrical wiring diagram.
  • If operating the instrument on power supply units, note that the power supply unit must be stabilized and it must comply with the following standard: DIN EN 61000, Parts 6-1 to 6-4.



WARNING Before beginning, disconnect the negative terminal on the battery, otherwise you risk a short circuit.

If the vehicle is supplied by auxiliary batteries, you must also disconnect the negative terminals on these batteries! Short circuits can cause fires, battery explosions and damages to other electronic systems. Please note that when you disconnect the battery, all volatile electronic memories lose their input values and must be reprogrammed.

  1. Before beginning, turn off the ignition and remove the ignition key. If necessary, remove the main circuit switch
  2. Disconnect the negative terminal on the battery. Make sure the battery cannot unintentionally restart.
  3. Place the device at least 300 mm away from any magnetic compass.


Depending on the sensor to be configured, connect the Link Up plug to the sensor according to the following pin assignment.
If the sensor is not equipped with the matching connector, it is possible to either crimp a male counterpart on it (see “Technical Data”), or simply cut-off the sensor plugs on the Link Up and manually connect the wires.
Veratron level sensors are already designed with the matching AMP connector for a plug-and-play installation.
The contacts must audibly lock into place.

  • Once the sensor installation is complete you can interface the Link Up gateway to the NMEA 2000® backbone through the dedicated plug.
  • Please ensure to tighten the M12 connector by screwing it onto its counterpart, so to preserve the water tightness.
  • A drop cable is not needed unless the total length of the Link Up device is not enough to reach the NMEA 2000® backbone. In this case it is possible to extend the total length by using one of the accessory drop cables.
  • Please note that NMEA 2000® does not allow drop cables longer than 6 meters.
  • Refer to the NMEA 2000® standard for a proper network design.
  • If power from the NMEA 2000® network is received, the green LED on the Link Up housing will start flashing (see “LED notifications”).
