    The Simrad IS42J Digital Gauge for diesel engines has a 4.1-inch color display that offers a clear view of engine status and performance for up to two J1939 diesel engines. More than a standalone gauge, the IS42J also bridges the gap between those engines and your boat’s NMEA 2000® network with a built-in J1939-to-NMEA 2000® Gateway.  This enables engine monitoring from other Simrad gauges and displays.

    Dual-Engine Display: The IS42J offers customizable views of engine status and performance data, for up to two J1939 diesel engines. View engine speed, load, pressures, temperatures, alerts (including diagnostic trouble codes), and other key data on one clear graphical display. Designed for use in all conditions, the IS42’s full-color display panel is optically bonded to its protective glass covering; this eliminates the possibility of condensation or fogging within the display. Simple, waterproof controls make the IS42 easy to use in rough conditions, and reliably responsive to wet or gloved hands.

    Easy Installation: The IS42J is simple to install, with one cable to each of your engines and a single connection to your boat’s DC power supply. With a dual-engine J1939 gateway built in, there are no separate "black-box" components to install. Plug-and-play adapter cables are available to suit a wide range of J1939 diesel engines. Sharing engine data with other Simrad gauges or displays is also simple, with industry-standard NMEA 2000® connectivity.

    Note — Minimum Product Requirements: Requires an engine-specific J1939 cable for each connected engine. An NMEA 2000® drop cable, joiner, and network infrastructure are required to share engine data with other gauges or displays.
