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.

IS20 Manual
V 1.0 4 of 23 2023
• Viewing angle - To be mounted at a suitable angle to ensure best visibility of the monitor. The
mounting location should be at or below eye level to provide optimal viewing as you operate your
vessel.
• Access - There must be suitable room behind the device to allow for the rear mounted connections, to
avoid sharp bends in any cables.
• Interference - the selected location should be far enough away from devices that may cause
interference, such as motors, generators, and radio transmitters.
• Magnetic compass - To avoid interference with a magnetic compass, the IS20 should not be installed
within the compass-safe distance value listed in the product specifications. For example, the AS08
needs 0.6 meters minimum distance.
• Airflow - to prevent overheating, do not restrict airflow at the rear of the display unit; ensure that there
is adequate ventilation, particularly if the display unit is pod-mounted.
2.1. Dash mounting
When dash mounting, the unit will be mounted on a flat surface with the provided bracket. If you are
mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat
layer when the screws are tightened.

Figure 2 Dash mounting
2.2. Flush mounting
Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance
between the case and the mounting holes, and cutting the hole too large could compromise the stability
of the device after it is mounted.
Do not use the device as a template when drilling the mounting holes because this may damage the
glass display and void the warranty. You must only use the included template to correctly drill the
mounting holes.

4.1. Power and NMEA 0183 input/output connector
The IS20 uses industry standard six-core screened M12 cable for power supply and NMEA 0183
input/output connection.
It operates on a 12V DC power supply. To properly connect the IS20, please follow these guidelines:
Connect the red wire to the positive supply (12V) using a 2-amp fuse, and securely connect the black
wire to the ground (GND). It is crucial to avoid connecting any of the other data wires to the 12V power
source, as doing so could potentially damage the device. Rest assured, the IS20 is equipped with
reverse polarity protection, ensuring the device remains safeguarded in the event of a faulty installation.
The IS20 can also be powered through the NMEA 2000 port using an N2K cable. When utilizing an
NMEA 2000 cable, we advise leaving the red and black wires open (please use tape or a suitable
protective measure to safeguard the header wire).
The NMEA 0183 input and output of the IS20 are galvanically isolated, in accordance with the NMEA
standard. Galvanic isolation, also known as opto-isolation, effectively prevents the flow of unwanted
currents between the instruments and the IS20. This protective feature against potential damage and
significantly reduces interference with radio signals.
The NMEA 0183 input of the IS20 supports two different baud rates: 4.8kbps and 38.4kbps. These baud
rates can be selected from the settings page, allowing you to choose the appropriate data source for the
IS20. The selected data source provides real-time data to the IS20, which is then displayed on the
screen for easy monitoring.
Furthermore, the IS20 has the capability to transmit (repeat) data from the NMEA 0183 input and send it
to other devices using NMEA 0183 wires. The output baud rate can be configured via the settings page.
If you wish to forward the data to a computer, you will need a TTL to USB adapter (not included). This
enables the input data to be displayed on software running on your computer, enhancing data visibility
and analysis capabilities.
4.2. Type-C connector
The IS20 is supplied with a type-C USB connector and USB cable for settings and upgrade its firmware.
The USB cable can be linked directly to a USB port on the Windows PC.
4.3. NMEA 2000 connector

Data sources provide live data to the system. Apart from NMEA 0183 input port, the IS20 can also be
connected to a NMEA 2000 network to receive NMEA 2000 data. The NMEA 2000 connector also
provides the power supply to IS20.
4.4. WiFi antenna
The supplied WiFi antenna needs to be connected to the SMA connector on rear. Connectivity in Station
Modes on 802.11 b/g/n provides WiFi input of all messages from a server (e.g. a wireless router). This
WiFi connection can also be disabled by setup into standby mode.
Connect the antenna by screwing them in clockwise until hand tight.
