1. Introduction
The IS20 is a networked multifunction instrument that provides you with the flexibility to display vital
instrument and navigation data. It consolidates multiple marine instrument functions into a single
display, thereby simplifying your on-board experience with the IS20.
Equipped with a high-brightness screen, the IS20 delivers a user-friendly and easily customizable
solution for displaying information from one of the following interfaces: NMEA 0183, NMEA 2000 bus
or WiFi network. It effortlessly presents a wide range of crucial data, including battery status, depth
readings, engine metrics, environmental conditions, fuel management details, GPS positioning,
heading information, navigation cues, rudder position, speed measurements, tank levels, time,
weather updates, and wind data.
To ensure seamless operation and continued support, the IS20 offers firmware updates that can be
conveniently maintained by connecting the device to the internet. This enables the addition of new
supported information and features over time. Furthermore, the instrument boasts programmable
audio and visual alarms, allowing you to create up to four alarms to guarantee optimal safety and
situational awareness while on board your vessel.
2. Mounting
The IS20 was designed with industrial level requirements in mind and is aimed at the commercial,
leisure, fishing boat and vessel monitoring markets. It is suited to both indoor and outdoor use and
can be dash or flush mounted.
When selecting a mounting location, the following considerations must be observed:
• Sturdy mounting surface -
The mounting surface must be strong enough to support the weight of the
device and protect it from excessive vibration or shock. Although the display unit is waterproof from the
front when installed correctly, it is good practice to mount it in a protected area, away from prolonged
and direct exposure to rain and salty seawater.
• Convenience
- the mounting location should allow easy access to the buttons on the device.
