Actisense NMEA 2000 Engine Monitoring Unit – Analog to NMEA 2000 Engine Gateway – EMU-1-BAS
The Actisense EMU-1-BAS Engine Monitoring Unit is a powerful analog-to-NMEA 2000 gateway that allows boaters to display critical engine data from traditional analog engines on modern NMEA 2000 networks and multifunction displays (MFDs). Designed for seamless integration, the EMU-1 converts analog sensor signals into standardized NMEA 2000 messages, giving you real-time engine monitoring without replacing existing engines or sensors.
Ideal for inboard, outboard, sterndrive, and generator engines, the EMU-1-BAS brings older or non-NMEA engines into today’s digital marine electronics ecosystem, enhancing situational awareness, safety, and performance monitoring.
🚤 Modern Engine Data on Digital Displays
The Actisense EMU-1 allows analog engine information—such as RPM, oil pressure, coolant temperature, alternator voltage, fuel rate, and alarm states—to be displayed on compatible chartplotters and engine displays from leading marine electronics brands. This eliminates the need for additional gauges and centralizes engine data on your helm display.
🔄 Flexible Analog-to-Digital Conversion
The EMU-1-BAS supports multiple analog inputs and configurable sensor types, making it compatible with a wide range of engines and sensor standards. Actisense’s configuration software allows precise calibration for accurate data translation across your NMEA 2000 network.
⚙️ Easy Installation & Network Integration
Designed for straightforward installation, the EMU-1-BAS connects directly to standard analog engine sensors and plugs into an existing NMEA 2000 backbone using industry-standard connectors. Once configured, engine data is automatically transmitted across the network to compatible displays and systems.
🛡️ Built for Marine Reliability
As with all Actisense products, the EMU-1 is engineered for harsh marine environments. Its robust housing and proven electronics ensure dependable performance in both saltwater and freshwater applications.

Key Benefits: The Digital Dashboard Upgrade
1. Monitor Everything on One Screen
Instead of squinting at individual, fogged-up analog gauges, the EMU-1 allows you to overlay engine data onto your chartplotter. You can monitor:
-
Engine RPM (via alternator "W" terminal, ignition coil, or sender).
-
Oil Pressure & Water Temperature.
-
Transmission Pressure & Temperature.
-
Fuel Level, Trim Position, and Battery Voltage.
-
Engine Hours (calculated and logged internally by the EMU-1).
2. Dual Engine Support
A single EMU-1 is flexible enough to monitor a single engine with many sensors or basic parameters for two engines (e.g., Dual RPM, Dual Temp, and Dual Pressure), provided the engines share a common ground.
3. Customizable Calibration
Because not all senders are the same, the EMU-1 is highly "tuneable." Using the Actisense Toolkit software, you can select from pre-defined sender curves (like VDO, Teleflex, or Stewart Warner) or create your own custom calibration for rare or vintage sensors.

| Protection | IP65 rated case (Electronic "potted" internals) |
| Mounting | Bulkhead or DIN Rail (with optional kit) |
⚠️ Critical Configuration Note
To set up the EMU-1 (choosing your engine type, calibrating gauges, etc.), you cannot use your chartplotter. You must have an Actisense NGT-1 or NGX-1 (PC Gateway) to connect the EMU-1 to a Windows computer running the free Actisense Toolkit software.
Without the NGT-1/NGX-1 gateway, the EMU-1 will remain in its default factory configuration.
Why Choose the EMU-1 Over Competitors?
-
Isolation: Features 2500V galvanic isolation to protect your NMEA 2000 network from engine-side electrical noise or surges.
-
Alarm Monitoring: It can digitize "dummy lights" (on/off switches) into digital alarms that pop up on your MFD.
-
Future Proof: firmware is flash-upgradable as new NMEA 2000 PGNs are developed.
Pro-Tip for Wiring:
"If you are 'sharing' a sender with an existing analog gauge on your dash, the EMU-1 must be set to 'Parallel' mode in the software. This ensures the EMU-1 doesn't interfere with the voltage reading the physical gauge needs to move its needle. If you've removed the old gauges entirely, set it to 'Series' mode to provide the necessary excitation current to the sensor."
