NEP-3, ETH 5-ports switch, 1 Gbps

The NEP-3 is a marine network switch with 5 Gigabit ports. It acts as a central hub to interconnect your multifunction displays, radars, fishfinder modules, and other navigation peripherals on your boat at very high speed.

It is compatible with 12 V and 24 V DC onboard electrical systems. Its accepted operating voltage range is 10.4 to 31.2 V DC.

Yes, the housing holds IPX6 and IPX7 waterproof certifications. It is fully protected against powerful water jets and can withstand temporary immersion, making it ideal for marine environments.

The NEP-3 is very energy-efficient. Its maximum power consumption is only 2.5 W (approximately 0.18 A at 13.8 V DC).

To properly protect the power circuit of your NEP-3 switch, use a 1 A fuse.

The NEP-3 ports use M12 coding X connectors. To connect a device with a standard RJ45 port, you will need a specific adapter cable (e.g., part number 000-16078-001) sold separately.

Navico provides a dedicated Ethernet adapter (part number 000-16448-001). It connects an M12 port with X coding (8-pin) from the NEP-3 to a female yellow 5-pin connector.

To avoid magnetic interference with your navigation instruments, you must maintain a minimum safe distance of 0.5 meters (1.6 feet) from the compass.

Each Ethernet port has an LED indicator: a steady green light indicates an active connection, while a flashing orange light shows ongoing data transfer activity.

Self-tapping screws No. 8 are included. For pilot holes:

Soft materials (plywood): drill at Ø 2.7–3.1 mm. Rigid materials (fiberglass, hardwood): drill at Ø 3.2–3.5 mm.

The switch is compact and lightweight, weighing only 0.48 kg (1.07 lbs).

Absolutely. Its Gigabit bandwidth (1 Gbps) is specifically optimized to handle the rapid and smooth transfer of the large data volumes generated by pulse-compression radars in the Halo series.

No, the NEP-3 is a plug-and-play switch. It requires no software configuration. Once powered and cables are connected, the network is immediately operational.

The box has 5 Gigabit Ethernet ports, allowing you to directly connect up to 5 compatible network devices.

The NEP-3 is designed for demanding environments and can operate within a temperature range of -15 °C to 55 °C. Ensure there is at least minimal air circulation.

Yes, the device is designed to withstand storage temperatures from -20 °C to 60 °C, making it perfectly suitable for winter storage in most climates.

No, Ethernet cables are not included with the unit. You will need to source M12 X-coded cables in the required length for your installation (available in 1.8 m, 5 m or 15 m).

The NEP-3 is distinguished primarily by its network transfer speed. It provides a Gigabit (1 Gbps) connection on each of its 5 ports, unlike the NEP-2 which was limited to 100 Mbps.

This significant increase in bandwidth is essential for quickly transferring heavy data from modern equipment, such as pulse-compression radars (e.g., the Halo series) or high-resolution fishfinder modules. Additionally, the NEP-3 uses M12 connectors with X-coding, offering superior robustness and waterproofing in marine environments.

The NEP-3 switch is designed to integrate easily into the electrical system of most vessels. Here are the power specifications to follow:

Power voltage: Compatible with 12 V and 24 V DC (operating range 10.4 to 31.2 V DC).Power consumption: Very efficient, it consumes a maximum of 2.5 W (0.18 A at 13.8 V DC).Protection: It is recommended to use a 1 A fuse to secure the installation.When mounting, also ensure a safety distance of 0.5 meters from your magnetic compass.

The NEP-3 acts as a central hub to interconnect navigation equipment from Simrad, B&G, and Lowrance brands. You can connect up to 5 devices, such as:

Multifunction displays (MFD)Radar antennasSounder modulesThe switch ports are equipped with M12 connectors (X-coded), ensuring IPX6 and IPX7 waterproofing. If you have devices using standard RJ45 connectors or the old 5-pin yellow plugs, official adapter cables are available for full compatibility.
