In addition to install the Pagoda antenna
(SMA interface) to
the
SMA Port
of
the
OJI
Goggles
RE,
you will also
need
to
install the OJI OcuSync Air System on a
third-party racing
drone
to
work with the
goggles. Refer to the illustration below
to
mount and connect the modules onto your
aircraft.

• The S.Bus Port
and
the
PPM Port
on
the
Air Unit are only used when transmitting the remote control signal
These ports
don't
need
to
be
connected if video downlink
is
used only.
• There are
up
to
19 channels (5.8 GHz: 12 channels, 2.4 GHz: 7 channels) tor digital video transmission,
and
each bandwidth is
10
MHz. You
can
select
the
transmission channel manually
to
avoid interference from
other devices.
• Please
be
aware that the Air Unit may
become
very hot during,
or
after operation. DO
NOT
touch it before it
has cooled
down
sufficiently.
• Please
avoid
using
the
Air
Unit
for
an
extended
time
when
there
is
no
external
cooling
equipment.
Otherwise, it
might
get
overheated
and
enter
into overheat protection
mode
Wait
for
the
module
to
cool
down
and
then you
can
restart it.
It
is recommended
to
have an external fan installed
to
dissipate heat.
• Place the
two
antennas on
the
Air Unit vertically
and
parallel
to
each
other
at
least
30
mm
apart. Please
note that you should avoid placing
the
antennas level with
any
type
of
conductor Also, make sure
to
keep
the
bottom
of
the
antenna
at
least
25
mm
away
from potential conductors like cables,
carbon
fiber frames,
batteries,
and
metals,
etc.
• If you are only using
the
Air Unit
to
transmit
the
downstream video signal,
DO
NOT use
the
same frequency
band
as the upstream control signal
to
avoid interference.
Antenna
Description
Pagoda Antenna
Cylindrical
Antenna
Dipole Antenna
5.8 GHz single frequency circular polarization omnidirectional,
small size, recommended for racing. Do not use this antenna
when using the 2.4 GHz frequency band.
Dual-frequency
circular polarization omnidirectional, providing a
smooth video transmission experience.
Dual-frequency linear polarization omnidirectional, suitable for
close-up flight.
After familiarizing yourself with the digital video transmission, you can connect the coach
port of a third-party remote controller and the audio port on the
OJI
Goggles
RE
through
the coach cable to transmit the control signal to the racing drone.
