I.R.I.S. 316 - Manual (Page 9)

6.01 Connections
As shown in the diagram below, a 3.5 meter ʻumbilicalʼ cable tail
extends from the base of the camera and is terminated with a
water resistant circular ʻAviationʼ connector. Into this connects a
500mm ʻBreakoutʼ lead, which has three separate tails as
shown. One for Video, one for DC 12V Power, and a third for
RS485 Serial Data connection.
6.02 Video Connections
The camera breakout tail features a male BNC connector for the
video signal. When using coaxial video extension cables that are
usually also supplied with a male BNC connector, a BNC ʻThru-
pieceʼ adapter can be used to connect the two cables together.
The camera has a composite video output (1VP~P / 75Ω).
Ensure appropriate extension cables are used for this
specification. Contact Iris Innovations for further information if
you are unsure which cable to use.
Many Multifunctional Displays (MFDʼs) / Chart Plotters use RCA
(Phono) jacks for video inputs. In this case use a female BNC to
Phone Jack (Male) adapter. These are available from Iris
Innovations and can also be sourced from any good home
electronics / AV suppliers.
Video from Iris cameras can be viewed on most leading
manufacturers MFD / Chart Plotter products.
6.03 Data Connections
Ensure correct polarity is observed when connecting the RS485
serial data wires that provide control of the camera. Wires are
labelled RS485+ (Red) and RS485- (Black) for convenience.
The Transmit line (RS485+) should be connected to the Receive
line (RS485-) and vice versa. If, once connected you have no
control, reverse the polarity of the data wires as this is a
common error made during installations. Never connect the
RS485 wires to a power source as this could permanently
damage the camera or controller. Observe care when
connecting as the RS485 wires are coloured red and black and
could be confused for DC power lines.
Even if the cable connections are made in an internal location or
in an area that wouldnʼt usually be exposed to moisture, it is
recommended that the connections are protected from any
possible erosion or salt water / salt atmosphere conditions by
wrapping the terminations in a suitable tape of covering.
6.04 Powering Up
Upon switching on the circuit breaker that isolates the camera,
the unit will perform an initialization routine. During this routine,
which lasts approximately 30 seconds, the camera will pan and
tilt automatically in order to calibrate itself. You will notice the
mechanical shutter 'wiping' the image frequently for the first few
minutes as the unit warms up. This will eventually settle into an
automatic interval of wiping approximately every 15 minutes.
This only lasts for a fraction of a second and allows the camera
to calibrate itself for the best possible image in accordance with
the ambient temperature.
Never apply power to the camera unless all connections are
terminated correctly. Never disconnect the DC ground for
any reason whilst the camera is powered up.
When the camera has completed its boot-up routine, a text
overlay table will appear in the screen displaying the camera
address, protocol, baud rate and current firmware version. You
will also notice the positional indicator icon in the bottom left
hand corner of the screen and the zoom bar at the center
bottom of the screen. When this message appears the camera
is ready to use and you are able to control the device.
