Standard Oblò installation
SECTION 1
1.1 MECHANICAL INSTALLATION
Oblò fits in a standard 3 1/8” (80 mm) cutouts. On the
panel it's necessary to make the cutout for the knob on
the lower right hole.
1)
The installation location must be carefully chosen since
Oblò contains magnetic sensors for the compass
indication. Given that a location without magnetic
interference can be difficult or impossible to find, it’s
recommended to install the instrument in the top row of
the instrument panel, to limit the interference of cables,
switches and breakers that are usually found at the
bottom.
Do not install near any magnetic sources (wires that
carry large amount of current, magnets/electromagnets,
electric motors, airplane parts or metal parts that may
have residual magnetic field). As a general rule keep a
minimum distance of 30cm, but 60cm or more are
recommended.
To test if the location where you intend to install it is
appropriate, turn on all the electrical loads (in particular
radio and strobe lights) and move a handheld compass
around the area making sure that the compass needle
is stable (should not cycles back and forth) and is
approximately indicating the magnetic North.
Small deviations from the North can be compensated
with the magnetic calibration (see chap.4.3)
2)
Mechanical installation

Avoid placing in hot locations (for example near heater
vents).
4)
Find a location where the display will always be
completely visible.
5)
During use the instrument become warm so it's
necessary to have some air circulation inside the
instruments room, to avoid that the temperature
increase over the operating limits.

1.2 ELECTRICAL AND PNEUMATIC
INSTALLATION
On the backpanel of the Oblò there is a 15 poles D-sub
plug connector, supplied with the corresponding 15-pole
receptacle, one static and one pitot port.
Use 1/8” NPT male fittings to connect the static
pressure (STATIC) and the dynamic pressure
(PITOT).
CAUTION: Don't blow air inside the fittings.

CAUTION: The connection of the external GPS is highly
recommended to increase the accuracy of the attitude
indicator. It is also required for the tracking indication and for
the automatic correction of magnetic declination.
If you connect a GPS that is not powered by the aircraft bus
(for example battery-powered), connect together the ground
of the GPS and of the Oblò. If no external GPS is available
use the Flybox® GPS cod. 810010.
Electrical installation
NOTE: Connections of pin#9-10-11-12 to a USB connector
is used for software upgrades and for datalogger function (in
development).

GENERAL WIRING HINTS:
- Take care to properly insulate any exposed wire to
avoid short circuits.
- Insert a 1-Ampere circuit breaker to the power lead
(+12V).
- Use aeronautic cable for the wiring.
CAUTION: Voltage peaks on the supply line that
exceeds the operating limits (20V) can damage the
device.
OPTIONAL ACCESSORIES AVAILABLE:
NOTE: Visit our web page
