For Aquatica housing with the optional Ikelite integrated conversion circuitry
The A7D Mk II model # 20077-KT is a housing is equipped with an Ikelite designed and patented TTL conversion
circuitry. Once attached to the housing, you should turn the strobe on first before turning the power on the camera.
When used with current Ikelite DS Strobes, the TTL Conversion Circuitry provides real flash exposure with over and underexposure
compensation from +1 1/3 to - 1 1/3 f-stops in 1/3 stop increments. The Conversion Circuitry also offers Manual exposure control with
3 f-stops of under exposure control in 1/2 stop increments. The Conversion Circuitry is powered by the Ikelite DS Strobe when connected
to the housing with the 4103.51 single or 4103.52 dual sync cord. When using two strobes with the dual sync cord, the primary strobe
connected to the cord without the red band, must be turned on to power the Conversion Circuitry. Always keep both strobes connected
to your dual sync cord underwater.
Setting the Conversion Circuitry Strobe ID Switch
Inside the back cover of the A7D Mk II housing is a switch for setting the DS Strobe ID.
Set the switch to the Model of DS Strobe being used.
Use (A) for DS-51 or (B) for DS 161,160, 125 & 200. Whenever using two Ikelite
strobes of different models such as a DS51 and a DS161, set the ID switch to (A)
DS51 or the smaller strobe.
Using the Conversion Circuitry (Set DS Strobe to TTL mode)
Mode and Compensation Dial (see illustration)
Note that the TTL compensation values are located in the yellow band. Manual compensation
values are located in the black band. Rotate the Dial to switch between TTL and Manual Modes.
TTL Mode compensation values are indicated in the yellow band. Place the Setting
Indicator to TTL for NO Compensation. Rotate the dial either direction to select
+/- compensation. Place the Setting Indicator to the desired compensation value. Note
that in TTL, compensation values are in 1/3 f-stops.
Manual Mode compensation values are indicated in the black band. Rotate the Dial to
place the
setting indicator to the desired compensation value. Note that in manual mode, compensation values
are in 1/2 f-stops from (F) full power to -3 f-stops. Set DS Strobe to TTL mode. This will allow the strobe power to be varied in manual mode.
Attaching the Flash Connection for external strobes
When using an external strobe, connect the housing hotshoe connector. Slide the connector
into the hotshoe mount on the camera from the back of the camera as shown. Slide the
connector forward until it stops. Make sure the hotshoe is all the way forward in the camera
mount to assure a good connection.
Using Non-Ikelite or Ikelite Non-DS Strobes (Strobe 50, 100A, 200, 400) with this Housing
The Conversion Circuitry is automatically disabled when used with a Non-Ikelite or Non-DS
Strobe. These Strobes can be used in their manual mode utilizing any power settings
provided on the Strobe.
For a complete list of compatible models of strobes, please check with Ikelite
(www.ikelite.com) to confirm that your strobe is compatible with this TTL circuitry
