Connectors
– Front
Lens
On the front of the unit are 2 x 12pin Hirose connectors. The female connector
duplicates the connector found on many cameras. Using this connector rather
than the camera connector gives the head the ability to control the iris directly and
the
zoom position
for the pre-set positioning functions. This connector also
provides power for the lens.
The male 12pin connector is a standard remote lens connector and outputs zoom,
focus & iris control for ‘remote-type’ lenses. If the lens is not a ‘remote-type’ and
has only one cable, you will need an adapter cable for the particular lens.
Note:
Canon & Fujinon broadcast lenses sometimes use similar connectors but
control the zoom on different pins.
Zoom Position Control
To use the positioning features of the
Proteân
, both 12pin
connectors may be required. This depends on the lens.
Iris Control
To control the iris from a non
BR Remote RCP
and
have zoom positioning control
the
iris input
connector needs fitting. This is a 4 pin Hirose connector. A 12pin to
4pin cable connects the camera lens connector to the iris input. The head reads
the iris commands from the camera and passes them on to the lens. It also
returns the iris position to the camera. To prevent accidental iris movement a
significant move is required to swap control from the Multi Function Controller to
the RCP and vice versa.
Lens Servo
If using external lens servos, this socket can be fitted and configured to
supply data and power for lens servos. An optional tally light can also be
fitted into this position.
