Thread the cables through the interface plate. Locate the pins
on the Tarot board. Connect the black wire to a - (ground) pin
and the white wire to the T (tilt) pin.

Follow these instructions to connect the gimbal to IRIS. This
will allow you to adjust the tilt of the camera in flight using the
controller. To enable automatic camera stabilization without
remote control, skip to the step 3: power.

the two holes in the interface plate and the two holes in the
bottom shell shown below.
Mount the gimbal
with the camera
facing forward.

Operating the Gimbal
Upon powering IRIS, the gimbal will display a solid yellow light
while it is starting and calibrating. Do not touch the gimbal while
it is starting up. When the gimbal displays a blinking blue light, it
is ready to fly.
If the gimbal is not connected to the autopilot, it will perform
automatic stabilization without remote control, indicated by a
solid blue light.
Calibrating, do not touch gimbal
Ready, connected to autopilot
Ready, not connected to autopilot
In flight, use the TILT knob on
the controller to adjust the angle
of the camera.

Important note: Flying with a gimbal will reduce your flight
time by as much as five minutes. Please plan your flights
accordingly.
