USING WIRED CONNECTORS
Internal switch board circuit:
Aquatica housings are available with electrical type strobe connectors; these come in single or double conguration, and are connected to an internal
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 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, if using sync cord with metal tting,
it is recommended that you remove them, and clean and lubricate the thread on a daily basis.
Canon Digital cameras are setup with a ash circuitry that only allows one eTTL ash to be connected directly to
the camera, Canon TTL Protocol will not allow two TTL ashes to be electrically connected directly, no matter if it is a Canon ash or any other brand. The
multiple ashes approach preferred by Canon prevents additional ashes, 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 a accurate and inexpensive way to consider (see next chapter)
On your housing you will nd either one or two bulkhead connectors, the main connector (on right side) is wired through a switch board that can be congured
for full manual ash 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 conguration and cannot be used for eTTL operation. By default you housing is delivered with the switch board set to full manual, if eTTL
exposure is desired then it can be made in either of two methods:
1) Using a single ash from Canon or other brand (that is eTTL compatible with your camera) in a dedicated underwater housing 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 ash or iTTL 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 ashes to be connected directly via the main and secondary bulkhead.

CONNECTING LIGHTING EQUIPMENT
Aquatica housings can be adapted to various types of strobe connectors. This feature
conveniently provides your camera system with access to the latest strobes
technology currently available on the market.
Standard options available are:
20074-NK: Two Standard Nikonos type 6 pins connectors.
20074-OPT: Two optical ber connectors with adapter to accept two
Sea & Sea angled type cords or two straight type cord (INON).
20074-HYB One Nikonos 6 pins and one Optical connector (to accept
either one Sea & Sea elbow type cord or two straight
standard Inon optical cords).
20074-KM One Ikelite manual type connector
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 # 44). Use
of the Aquatica Technical Lighting Control Strobe Arm System is recommended.
Three 1/4”-20 threaded holes on the bottom (key # 46) 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 # 45), and is ready to accept a Technical Lighting Control
1”/25mm Ball (# 17651) for adapting a small dive light or an additional strobe arm
can be attached using a clamp.
