CONNECTING LIGHTING EQUIPMENT
Mounting the strobe arms will require that the necessary shoes, brackets or Base Ball be attached to the threaded holes located on the top
of the hand grips (key # 26). Use of the Aquatica Delta 3 Strobe Arm System is recommended.
Three 1/4”-20 threaded holes on the bottom (key # 53) of this housing can be used for various mounting applications. A similar sized 1/4”-20
hole with thread is located on top of the housing (key # 27), and is ready to accept a 1”/25mm Technical Lighting Control Delta 3 (# 77651)
for adapting a small dive light or an additional strobe arm can be attached using a clamp.
USING WIRED CONNECTORS
Internal switch board circuit:
If your Aquatica housings was delivered with electrical type strobe connectors, it will have a single or double strobe connections which
will be connected to a switchboard inside the housing. The following chapter explains the various options available and the limitation of
current underwater strobe technology.
When preparing the sync cord, be sure to lubricate the O-ring on the sync cord’s connector with a light coat of the strobe manufacturer
original O-ring lubricant, also advisable is to put a light coat of O-ring lubricant on the threads of this connector to help prevent threads
from freezing up. Some electrical sync cord are known to use dissimilar metal in their construction, these can create an unwanted electrolytic
reaction. Whenever using sync cord with metal fitting, it is recommended that they be removed, cleaned and the threads lubricated on a
daily basis.
Canon Digital cameras are setup with a flash circuitry that only allows one eTTL flash
to be connected directly to the camera, Canon TTL Protocol will not allow two TTL flashes
to be electrically connected directly, no matter if it is a Canon flash or any other brand.
The multiple flashes approach preferred by Canon prevents additional flashes, or strobes
from being connected directly to the camera in eTTL mode, exposure will stop to function
and a camera freeze is likely to happen. Two underwater strobes can only be connected
electrically if a TTL converter is interfaced between the camera and the strobe. If seeking
TTL exposure, Optical triggering is an accurate and inexpensive way to consider (see next
chapter)
The main connector (on right side) is wired through a switch board that can be configured for full manual flash exposure or setup to be
compliant with the latest TTL converter on the market. The secondary connector (left side if installed) is wired in a full manual configuration
and cannot be used for eTTL operation. By default you housing is delivered with the switch on the board set to full manual (down) position.
If eTTL exposure is desired then it can be made in either of two methods:
1) Using a single flash from Canon or other brand (that is eTTL compatible with your camera) in a third party dedicated underwater housing,
which will be connected with a TTL cord to the Nikonos 6 pins main connector of your Aquatica housing.
2) Using an external eTTL converter connected to the main connector of your Aquatica housing, one or two underwater strobes with TTL
cords can then be connected to this converter, (check with your dealer or the strobes manufacturer to see if the strobes and converter
are compatible between themselves).
Set up instruction for eTTL operation: Using the tip of a pen push all the switches to the ON (up) position, this will activate the connections
on your main bulkhead connector allowing TTL communication between the camera and the housed flash or eTTL converter.
Set up instruction for manual operation: All switches must be in the OFF (lower) position, in this case all eTTL connection are disabled
and only the ground and sync are left active, this will allow two under water strobes or housed flashes to be connected directly via the
main and secondary bulkhead.

If your housing was delivered with an Internal Ikelite TTL circuit, please refer to the separate instruction
sheet enclosed your housing documents.
