This is an overview only. Familiarize yourself with the manual and the manuals of
any connecting devices before installation. It is always recommended that electronic
equipment be installed by an experienced installer.

MOUNTING:
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.
•
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.
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.
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.
Inspecting all the wiring connections to ensure they are properly and securely
installed before powering up the IS20.
FRONT PANEL AND BUTTONS
Use the buttons to operate the display. Each button has multiple functions.

CONNECTING THE DISPLAY
The IS20 has the following options for connection
to inputs, outputs and host devices at rear (from
left to right):
•
Type
-
C USB connector
•
Power/ NMEA 0183 input & output
connector
•
NMEA 2000 connector

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.
* Power
The IS20 operates on a 12V DC power supply. 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).
