Housing Conversion Circuitry
This housing has Conversion Circuitry built into the camera tray, page 7.
When used with Ikelite DS Substrobes, the Conversion Circuitry
provides real Canon eTTL flash exposure with over and underexposure
compensation of two f-stops in half-stop increments.
The Conversion Circuitry also offers 8 manual power settings in 1/2 stop
increments and is powered by the Ikelite DS Substrobe when connected
to the housing with the #4103.51 single or #4103.52 dual sync cord.
Using the Conversion Circuitry
-
Mode and Compensation Buttons
The Conversion Circuitry default is set to TTL. To switch between TTL and
Manual Modes, depress both Mode Buttons at the same time and keep
them depressed until you see the desired Yellow LED Mode illuminate.
-
TTL Mode (indicated when the yellow LED directly below TTL is
illuminated). TTL Mode is the default setting. When the DS Substrobe is
powered ON, the yellow TTL LED will illuminate. None of the Red LEDs
will illuminate. This indicates that no (+) plus or (-) minus compensation is
selected. Depress the Mode buttons to select +/- compensation. Note that
the TTL +/- compensation values are in the yellow bar with the heading
TTL.
-
Manual Mode (indicated when the yellow LED directly below the M is
illuminated). When the Manual Mode is selected, the Red LED directly
below the F (full power) will illuminate. Note that the Manual minus (-)
compensation values are in the black bar with the heading M. Set DS
Substrobe to TTL mode. This will allow the strobe power to be varied
in manual mode.
