IS20
* NMEA 0183 input/output The NMEA 0183 input supports two dierent baud rates: 4.8kbps
and 38.4kbps. These baud rates can be selected from the sengs page, allowing you to choose
the appropriate data source for the IS20. The selected data source provides real-me 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 output wires. 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 soware running on your computer, enhancing data visibility and analysis capabili-
es.
The IS20 input/output interface is based on NMEA 0183-RS422 (dierenal) protocol.
For RS422 interface devices , connect ‘+’ to ‘+’ wire of IS20, and ‘-’ to ‘-’ wire of IS20. Swap ‘+’ and
‘–’ wires if the IS20 does not work.
For RS232 interface device( single end), connect TX/RX to NMEA input/output ’-’ and GND to
input/output ’+’. Swap TX/RX and GND wires if the IS20 does not work.
Type-C connector
The IS20 is supplied with a type-C USB connector and USB cable for sengs and upgrade its rm-
ware. The USB cable can be linked directly to a USB port on the Windows PC.
NMEA 2000 connector
The IS20 provides a standard male NMEA 2000 connector. It 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.

GETTING STARTED
Turning the unit on and o
The IS20 oers two opons for powering the device: through the N2K connector or the power
cable connected to the Power and NMEA 0183 input/output connector. Once power is supplied,
press and hold the POWER buon for 3 seconds to turn on the screen. The Quark-elec logo will
be displayed, followed by a legal noce page upon compleon of the inializaon process. To
proceed, simply tap 'Accept', and the default page will be presented.
To power o the IS20, press and hold the POWER buon for 5 seconds while the display is acve.
Adjust the brightness
When the IS20's screen is acve, pressing and holding the central area of the screen will bring up
the brightness seng page. From this page, you can conveniently adjust the screen brightness to
your desired level, ensuring opmal visibility in dierent lighng condions.
Setup
For more details on how to setup IS20 and operaon, please refer to the manual, which can be
found on the Quark-elec website.

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).
