EMU-1 Engine Compatibility and Setup

← Back

In order to confirm that the EMU-1 will be compatible with your system, please identify the manufacturer of the gauges (VDO, Faria, US Marine, Yanmar etc…) and the range of values (40 to 140 degrees C, 0 to 5 Bar etc…).  Once confirmed, refer to the table below to determine whether your gauges are compatible. 

Note: The manufacturer of the engine is not relevant, it is the sender / gauge manufacturer that is important.

All of the senders/gauges on the current list are standard resistance senders/gauges.  The EMU-1 is not yet compatible with constant current (4-20 mA) senders/gauges.

Tachometer gauges are not listed because the EMU-1 only needs to have the Pulses Per Revolution (PPR) entered into the configuration. The PPR can usually be found by contacting your engine manufacturer or in the engine documentation. 

The EMU-1 can be connected in parallel to existing gauges or as a replacement for some or all of the gauges. The EMU-1 automatically detects whether a gauge is present or not and configures itself to provide a current feed to the sender where required.

If your gauge is not listed below, you can use the ‘Custom Gauge Manager’ in Toolkit to configure your own gauge. If you require further instructions for using the Custom Gauge Tool then please contact Technical Support.

Supported NMEA 2000 Data (PGNs)

The EMU-1 will transmit the converted analogue data from your engines gauges/senders as standard NMEA 2000 engine data PGNs, making the device compatible with MFD’s/PC software that also use these standard NMEA 2000 PGNs.  To ensure your engine monitoring display is compatible for use with the EMU-1, please check which NMEA 2000 PGN’s your display supports against the PGN list below.

Dual Station Senders

The EMU-1 is compatible with both single and dual station senders.

A dual station sender must always have two gauges connected to it: the EMU-1 cannot replace one or both of those gauges. If it is required to remove one or both gauges, the dual station sender will need to be replaced with a single station sender.

Recommended Wire Gauge

The recommended wire to use between the gauge/sensor and the EMU-1 connectors is a minimum of 24 AWG (0.5mm diameter).
