Engine Guage IS42J & Gateway J1939

The IS42J Digital Gauge is an advanced, high-precision instrument designed to deliver accurate measurements and readings in various applications. Featuring a sleek, modern design, this gauge integrates seamlessly into both marine and industrial environments. The IS42J offers a large, easy-to-read digital display that provides clear and precise readings. Its user-friendly interface allows for quick and intuitive navigation through settings and functions. The gauge is engineered with robust electronics and high-quality components, ensuring reliability and durability even under harsh conditions. With its versatile functionality, the IS42J can measure a range of parameters including voltage, current, and temperature, making it a versatile tool for monitoring and diagnostics. The gauge supports multiple units of measurement and offers customizable settings to suit specific needs. The IS42J is designed for straightforward installation, with various mounting options available to fit different setups. Its rugged construction is built to withstand environmental stresses such as moisture, vibration, and temperature extremes, ensuring consistent performance in challenging conditions.
Dual-Engine Display
The IS42J offers customisable 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-colour 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.

Built-in J1939 to NMEA 2000® Gateway
More than a standalone gauge, the IS42J also links your J1939 diesel engines to your boat’s NMEA 2000® network. This lets you view engine data on a wide range of other Simrad gauges and multifunction displays vessel-wide, without the need for a separate J1939 gateway or converter.

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 adaptor 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.
