respective jacks on the power supply.
3. Plug the BNC connector on the topside of the
cable into the monitor or VCR video-in jack (a
BNC-to-RCA adapter may be required by the
monitor/VCR in use).
4. Lubricate the camera bulkhead connector with an
appropriate silicone lubricant (spray type rec-
ommended), and using a linear motion plug the
female inline connector into the male bulkhead
connector on the back of the camera.
5. Screw the locking sleeves together firmly (hand
tight-do not use tools). The camera is now ready
for operation; switch the power supply ON to
power the camera. The camera draws a maxi-
mum of 410mA of current during operation, and
will work when supplied between 11-30 volts DC.
LED Ring Operation
The LED ring built into this camera will operate in four
modes: Hi, Med, low, Off. The illumination is adjust-
ed by toggling the power to the camera on and off. If
camera is powered by a buffered power supply, leave
switch in off position for at least 3 seconds when tog-
gling through LED illumination levels. If power is off for
more than 10 seconds the camera will default to the Hi
setting.
DANGER
After each deployment, carefully check to
make sure the camera has not flooded. It is possi-
ble for the camera to partially flood and then reseal
itself while underwater. Upon surfacing, the camera
can become internally pressurized, which may be
potentially dangerous. Additionally, if the power
remains on when the camera has partially flooded,
it is possible for electrolytic generation of an ex-
plosive mixture of hydrogen and oxygen gases. If
a camera appears flooded upon removal from the
water, it should be treated as potentially dangerous.
Point the camera away from persons and valuable
equipment and make sure that the power is discon-
nected. See the Flooding Repair Procedure for more
information.
Flooding Repair Procedure
If the camera stops working while underwater,
you should assume that it has been flooded. When
working on a potentially flooded camera, it is important
to use appropriate personal protective equipment to
include, at a minimum, eye and hand protection.
1. Immediately turn off the power to the unit.
2. Open the housing by removing the rear end
cap-retaining ring. Grasp the rear end cap in one
hand and the camera housing in the other. With
care, separate the two components using a linear
motion. If required gently twist components while
separating.
3. Pour out any water trapped in the housing.
4. If the camera is completely flooded, rinse the in-
ternal components with clean fresh water in order
to minimize contamination and corrosion.
5. Allow parts to dry in air or a convection oven set
at 60° C (190° F). IMPORTANT! DeepSea Power
& Light cannot be responsible for any damage
incurred during emergency field repairs. Such re-
pairs should be undertaken only as a last resort
and by qualified personnel.
Troubleshooting
1. If the camera stops working while underwater
assume that it has been flooded. See Flooding
Repair procedure.
2. Once it has been determined that the camera
is not flooded, or if it does not turn on during
pre-deployment checks, troubleshoot in the fol-
lowing sequence:
a. Check the cable/inline connector to make
sure that correct voltage and current
are being supplied, and that the correct
sockets are being used. See page 2 of this
manual for electrical specs and connector
pin-outs.
b. Remove the connector. Inspect the as-
sembly for visual signs of wear. Use a
multi-meter check for continuity or shorts
in the connector. Try a spare connector, if
available.
c. Check the wires that go from the power
supply to the camera base for wear. If they
appear worn, replace them.
d. Check to make sure that the power supply
board is securely attached to the camera. If
it is loose, check for damage on the board.
If there appears to be no damage, reattach
the board to the camera. Try using a spare
driver board if available.
e. If the camera still does not work, return it to
DSPL using the RMA Procedure.
