Tlačítko MOB NMEA2000

This button is an essential safety device. Its main function is to trigger a "Man Overboard" (MOB) alert on all compatible devices connected to your NMEA 2000 network. A single press instantly marks the GPS position of the incident to assist rescue operations.

Installation is straightforward. The button connects directly to your existing NMEA 2000 network (backbone) using a standard Micro-C connector. No additional connections are required.

Yes, very likely. This button uses the standard NMEA 2000 PGN 127233 sentence for the "Man Overboard" notification. It is therefore compatible with most NMEA 2000-certified multifunction displays and chartplotters that recognize this PGN, including those from brands such as Lowrance, Simrad, B&G, Garmin, Raymarine, etc.

Yes, it is designed for the marine environment. It has an IP67 protection rating, which ensures total protection against dust and resistance to temporary immersion in water.

No, the button is powered directly by the NMEA 2000 network. It does not require a separate power cable. Its power consumption is very low, equivalent to 1 LEN (Load Equivalency Number).

When you press the button, it sends a signal (PGN 127233) over the NMEA 2000 network. Compatible displays will then:

Activate MOB (Man Overboard) mode.Create a waypoint at the GPS position of the incident.Display a dedicated navigation screen to return to this point.Potentially trigger an audible alarm.

The electrical consumption is very low. It is 1 LEN (Load Equivalency Number), which corresponds to 0.39 W, or approximately 28 mA at a voltage of 13.8 V. This represents a minimal load for your NMEA 2000 network.

Yes, absolutely. This button is manufactured by Navico, the parent company of the Simrad, Lowrance, and B&G brands. It is therefore designed for seamless integration and full compatibility with the systems of these brands.

It is crucial to install it in a location that is easily and quickly accessible in case of an emergency. The most common spots are the cockpit, near the helm, or at the chart table.

The MOB NMEA2000 button is designed to operate within a wide temperature range, from -15°C to 55°C (5°F to 131°F).

It uses a standard NMEA 2000 Micro-C connector, ensuring compatibility with all cables and connectors of this type.

The button transmits PGN (Parameter Group Number) 127233. This is the universal standard notification for a "Crew Overboard Notification" alert.

Yes, the device includes reverse polarity protection, which prevents damage in case of incorrect electrical connection to the network.

The button is very light, weighing only 0.13 kg (130 grams), making it easy to install on any bulkhead without requiring additional reinforcement.

Generally, no. NMEA 2000-certified devices are designed to automatically recognize standard PGNs such as 127233. Once the device is connected to the network, it should be recognized and functional without any manual configuration.

The button is powered by the NMEA 2000 network. It operates with a nominal voltage of 12 V DC and supports an operating voltage range from 9 V DC to 18 V DC.

MOB is the acronym for the English expression "Man Overboard", which translates to French as "Homme à la mer". It refers to an emergency situation where a person has fallen overboard from a vessel.

This button communicates exclusively via the NMEA 2000 network. It is not compatible with NMEA 0183 or Ethernet networks.

No, the installation is considered very simple for anyone familiar with NMEA 2000 networks. It consists of inserting a T-connector on your main backbone cable and plugging in the button’s cable.

The NMEA2000 MOB button complies with the following standards:
