Simrad NSO evo3S Processor, Dual Monitor Support, 9-31.2V DC, IPX2, NMEA 2000, Ethernet

Overview

The Simrad 000-15100-001 is the NSO evo3S MPU processor that lets you build a modular, multi-display navigation system around a below-deck processor. It runs on 9 to 31.2 V DC and supports dual-monitor operation, so you can set up one helm with two screens or split displays across stations, depending on how your boat is laid out.

This processor is built to sit at the center of a vessel-wide electronics network. With Ethernet, NMEA 2000, and NMEA 0183 on board, it ties charts, radar, sonar modules, autopilot control, and shared instrument data together across connected displays and accessories. It also supports video integration with 2 video inputs and 1 video output, which is useful when you want cameras or other video sources on your screens.

The housing is rated IPX2, so it belongs in a protected mounting location inside the boat, not in a spot that takes spray or washdowns. Plan cable routing and service access before mounting so power, networking, and video connections stay easy to reach.

Key features

• 9 to 31.2 V DC input, compatible with typical 12 V and 24 V onboard power systems.
• Dual monitor support for multi-display helms and multi-station layouts.
• Supports both touchscreen and non-touch monitors, giving flexibility for open-helm and enclosed pilothouse installs.
• Two quad-core processors for fast response when switching between charts, radar, sonar, and system pages.
• Ethernet plus NMEA 2000 for networking sensors, modules, and accessories across the vessel.
• NMEA 0183 support alongside NMEA 2000 for integrating older serial devices and data sources.
• Video integration with 2 video inputs and 1 video output for cameras and other onboard video sources.
• Wi-Fi compatible when paired with an external module, for wireless networking where supported.

Installation and setup

Mount the processor where it stays protected from direct water exposure and where cables can be secured against vibration. The unit measures 281 x 232 x 66 mm (11 x 9.1 x 2.5 in), which helps when planning space inside a console, helm cabinet, or an equipment locker.

Allow room for network and video cabling and leave enough slack for service access. If your build includes multiple displays, map the monitor locations and cable runs first so the system stays clean and easy to troubleshoot later.

Compatibility and system integration

This NSO evo3S processor is commonly used on larger boats, including powerboats around 33 ft (10 m) and up, where a modular multi-display setup makes sense. It supports vessel-wide integration through Ethernet and marine networking, and it can be expanded with compatible navigation, radar, sonar, and autopilot components as your system grows.

If you are tying into an existing network, confirm that your displays, sensors, and third-party devices match the network types you plan to use (Ethernet, NMEA 2000, and NMEA 0183). That quick check up front avoids surprises during commissioning.

Use cases on board

This processor fits well when you want two screens at one helm, separate stations at different helm positions, or a network where multiple displays share the same charting and sensor sources. It also suits installs where video inputs matter, such as adding a docking camera view to your navigation screens.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
