Overview

The Lumitec 101925 is a Poco 4 digital lighting control module that runs a multi-zone onboard lighting system through a connected display or smart device, so you can manage scenes and zones without a panel full of individual switches. It operates on 10 VDC to 30 VDC and provides four output channels rated up to 10 A per channel.

The enclosure is white, sealed, and IP67 rated, with a compact footprint of about 5.5 in wide, 3.5 in high, and 1.24 in deep for installs behind helm stations, inside consoles, or in other tight utility spaces. Operating temperature is -35 C to 55 C for use across typical marine environments.

This module supports Lumitec PLI-enabled light control, Timed Toggled Protocol (TTP), and integrates over NMEA 2000 and CAN bus for unified control alongside other onboard electronics. It replaces discontinued Lumitec 101699 when updating an existing system.

Key features

• Four output channels, up to 10 A per channel for separate lighting zones or loads
• 10 VDC to 30 VDC input range for 12 V and 24 V DC systems
• IP67-rated sealed enclosure for damp compartments and washdown-prone areas when installed correctly
• NMEA 2000 and CAN bus integration for control from compatible MFDs and digital interfaces
• Supports Lumitec PLI control and Timed Toggled Protocol (TTP) behavior
• Compatible with Lumitec Pico expansion modules to bring additional circuits and non-PLI loads under control
• Sound-to-light mode for lighting effects that react to onboard audio
• Compact size: approximately 5.5 in x 3.5 in x 1.24 in for space-conscious installations
• Rated operating temperature: -35 C to 55 C

Installation and setup

Plan the mounting location where wiring can be routed cleanly and where you can still access terminals and network connections for service. Even with an IP67 enclosure, good practice is to keep the module out of standing water and to provide strain relief on cables so vibration does not work connections loose over time.

When laying out zones, map each output channel to a real onboard area such as cockpit, hardtop, cabin, or deck lighting. Keeping zones aligned with how the boat is used makes it easier to build scenes that feel natural underway, at anchor, and during docking.

Electrical and system integration

The module is intended for DC systems from 10 VDC to 30 VDC, which covers common 12 V and 24 V boats. Size your supply wiring and overcurrent protection for the loads you are switching and the combined current you may run at one time, and keep all connections clean and protected from corrosion.

For NMEA 2000 integration, treat it like any other network device on a properly terminated backbone. Stable network power and correct backbone layout help prevent control dropouts and make lighting control feel immediate at the helm.

Compatibility and control

Poco 4 is built around Lumitec PLI-enabled lighting control and supports TTP behavior for consistent control across supported lights. Pico expansion module compatibility allows additional channels and non-PLI lighting or accessories to be brought into the same control scheme, which is useful when refitting a boat that already has mixed-brand loads.

This is a good fit for boats where the goal is centralized lighting control from a multifunction display or a handheld device while keeping wiring runs and switch panels more manageable.

Maintenance and care

Periodically inspect power and network connections for corrosion, chafe, and loosened fasteners, especially after the first few outings and after heavy-weather runs. If the module is installed in a locker or console that gets wet, keep the compartment ventilated and support wiring so connectors are not carrying the weight of the harness.
