Quark-Elec IS20 - Page 2

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

MOUNTING:
When selecng a mounng locaon, the following consideraons must be observed:
• Sturdy mounng surface - The mounng surface must be strong enough to support the weight
of the device and protect it from excessive vibraon or shock. Although the display unit is
waterproof from the front when installed correctly, it is good pracce to mount it in a protected
area, away from prolonged and direct exposure to rain and salty seawater.
• Convenience - the mounng locaon should allow easy access to the buons on the device.
• Viewing angle - To be mounted at a suitable angle to ensure best visibility of the monitor. The
mounng locaon should be at or below eye level to provide opmal viewing as you operate
your vessel.
• Access - There must be suitable room behind the device to allow for the rear mounted
connecons, to avoid sharp bends in any cables.
• Interference - the selected locaon should be far enough away from devices that may cause
interference, such as motors, generators, and radio transmiers.
• Magnec compass - To avoid interference with a magnec compass, the IS20 should not be
installed within the compass-safe distance value listed in the product specicaons. For example,
the AS08 needs 0.6 meters minimum distance.
• Airow - to prevent overheang, do not restrict airow at the rear of the display unit; ensure
that there is adequate venlaon, parcularly if the display unit is pod-mounted.
Dash mounng
When dash mounng, the unit will be mounted on a at surface with the provided bracket. If
you are mounng the bracket on berglass 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 ghtened.
Flush mounng
Be careful when cung the hole to ush mount the device. There is only a small amount of
clearance between the case and the mounng holes, and cung the hole too large could
compromise the stability of the device aer it is mounted.
Do not use the device as a template when drilling the mounng holes because this may damage
the glass display and void the warranty. You must only use the included template to correctly
drill the mounng holes.
Inspecng all the wiring connecons to ensure they are properly and securely
installed before powering up the IS20.

CONNECTING THE DISPLAY
The IS20 has the following opons for connecon
to inputs, outputs and host devices at rear (from
le to right):
• Type-C USB connector
• Power/ NMEA 0183 input & output
connector
• NMEA 2000 connector
• WiFi antenna
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 connecon.
* Power The IS20 operates on a 12V DC power supply. Please follow these guidelines: Connect
the red wire to the posive supply (12V) using a 2-amp fuse, and securely connect the black wire
to the ground (GND). It is crucial to avoid connecng any of the other data wires to the 12V
power source, as doing so could potenally damage the device. Rest assured, the IS20 is
equipped with reverse polarity protecon, ensuring the device remains safeguarded in the event
of a faulty installaon.
The IS20 can also be powered through the NMEA 2000 port using an N2K cable. When ulizing an
NMEA 2000 cable, we advise leaving the red and black wires open (please use tape or a suitable
protecve measure to safeguard the header wire).
