The Fox Marine MEFI-4 Engine Gateway plugs in to the 10-pin diagnostic connector on the wiring harness of your MEFI-4 ECM. Engine data is obtained and transmitted over your NMEA 2000 (N2k) compatible network so that it can be viewed on your N2k compatible GPS/Multi-function Display. Engine RPM is transmitted twice per second while the remaining data is transmitted once per second: Fuel Flow Rate, Coolant Temperature, Alternator/Battery Voltage, Engine Run Hours, Throttle Position (Engine Load), and Active Alarms. Oil Pressure is transmitted with the purchase and installation of the optional Oil Pressure Kit. The optional Oil Pressure Kit includes: pre-loaded Engine Gateway Oil Pressure Software, a 100 psig Oil Pressure sending unit, an 1/8" pipe restrictor orfice, an 1/8" pipe nipple, an 1/8" pipe tee, and a 3-wire oil pressure data cable (8.5 feet).
Engine data is also transmitted over Bluetooth Low Energy (BLE) to allow your phone/tablet to serve as the viewing medium for additional data and provides the function of an input device to manage settings. Data broadcasted over BLE is more extensive and is similar to what would be available to be seen on a dealership diagnostic scanner. Active alarm codes can also be cleared using the app.
One gateway is required for each engine.
The MEFI data cable attached to the gateway is 8.5 feet in length. The N2k connection is a standard male micro-c N2k compatible connector.
Product purchase includes: 1 MEFI-4 Engine Gateway, 4 stainless steel mounting screws (#10 x 3/4"), 4 zip ties (8").
Products listed as NMEA 2000 or N2k compatible are neither registered nor certified by the National Marine Electronics Association. Claims of compatibility simply mean the products were designed to function on a CAN Bus operating at 250kbps and that data is organized in publicly available parameter group number formats allowing other N2k compatible devices and displays to interpret the data.
