Overview

The Simrad NSO evo3S is a glass-helm multifunction display for running charting, radar, sonar, and boat data from one screen. It uses a 1920 x 1080 Full HD multi-touch display with 1000 nits of brightness, and the iMX 8 integrated six-core processor keeps scrolling and screen changes responsive.

Power is 12/24 V DC (10 - 31.2 V DC input range). Behind the dash you get the wiring and I/O you expect for a networked helm, including Ethernet, NMEA 2000, J1939, and NMEA 0183, plus HDMI and video inputs for cameras.

Key features

• Full HD 1920 x 1080 multi-touch display with 1000-nit backlight and 80° viewing angles
• iMX 8 integrated six-core processor for fast screen response and smooth transitions
• Six-panel split-screen layout for running multiple views at once
• 12/24 V DC power support (10 - 31.2 V DC input range)
• Front face rated IPX6 when panel mounted correctly with only the front exposed
• Network connections: 3x Ethernet (RJ45), NMEA 2000 (Micro-C), J1939, and 4x NMEA 0183 ports
• Video and accessories: HDMI in and out (1080p), 2x composite video inputs (BNC), 3x USB-A ports, and 1x microSD slot
• Built-in Wi-Fi (802.11b/g/n) for mobile-device connections and online updates via hotspot

Variants

NSO evo3S is offered with 16, 19, and 24 inch widescreen displays, and each size is available as a Display Only package or a System Pack.

System Packs include core add-ons such as a keypad, a GPS antenna, and a chart card reader, and they also include an NMEA 2000 starter kit. Across the range you keep the same Full HD resolution, multi-touch interface, and core connectivity, while power draw and fuse sizing increase with the larger screens.

Installation and helm fit

For a helm install that can handle spray and washdowns, panel mount the unit so only the front is exposed, and keep the rear connections in a dry space behind the dash. Bracket mounting is also supported using an optional bracket kit. Leave room for cable bends and airflow, and maintain a 50 cm compass-safe distance.

Maximum power consumption is 40 W (16 inch), 50 W (19 inch), or 80 W (24 inch). Recommended fuse ratings at 12 V DC are 6 A, 7 A, and 10 A respectively.

Electrical and system integration

Three Ethernet ports make it straightforward to tie in radar and other high-bandwidth accessories, while NMEA 2000 and J1939 handle engine and vessel data on a backbone. The four NMEA 0183 ports support legacy talkers and listeners. HDMI in and out support 1080p video, and the two composite video inputs are handy for onboard cameras.

Use the microSD slot for chart cards, updates, backups, and user data transfer. The USB-A ports support common accessories like a keyboard, mouse, or storage device.

Use on board

The six-panel split screen works well when you want charting, radar, sounder views, and engine data visible at the same time. For sonar and fishfinding, you will still need a compatible transducer and a sonar source on the network; for radar, add a compatible scanner over Ethernet.

This setup makes sense for boats running a networked helm, including larger center consoles, offshore sportfish boats, and cruisers that want a consistent display family across the dash.

Maintenance and care

Use the suncover when the boat is parked, rinse salt spray off the front after washdowns, and support cables so connector strain stays low. If the unit is panel mounted, check the gasket seal and fasteners as part of routine service to keep the front seal doing its job.
