Using External Strobes

This housing has Conversion Circuitry built into the camera tray. When used with Ikelite DS Substrobes the Conversion Circuitry provides real Canon eTTL flash exposure with over and under-exposure compensation of two f-stops in half-stop increments.

Port Seal Inside View

If the port is installed before the camera is inserted into the housing, look on the inside of the housings at the port seal. Check to see that the o’ring is properly sealed as shown in figure 1 andnot extruded as shown in figure 2.

The Consversion Circuitry also offers Manual exposure control with 3 1/2 f-stops of under-exposure control in 1/2stop increments.

The Conversion Circuitry is powered by the Ikelite DS Substrobe when connected to the housing with the #4103.51 single or #4103.52 dual sync cord.

See page 12for DS Substrobe compatibility with the Conversion Circuitry.

Caution:

After installing the port, turnthe Zoom Control knob on the housing. If the Zoom Control is difficult to turn, the gear sleeve may be warped. If so reduce or omit any rubber installed on the Zoom Clamp. (Fig.H on pg.11). If the Zoom Clamp is stillwarped, use of the #5509.28package may be required. (See page 7)

Using the ConversionYellow LED Circuitry (Set DS Substrboe to TTL mode)

• 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 then 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 isselected. Depress the Mode buttons to select +/- compensation. Note that the TTL +/- compensation values are in the yelow 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 Substrboe to TTL mode)

NOTE:

If the camera is busy with a function such as displaying a photograph on the LCD panel the Conversion Circuitry cannot be accessed to make changes. Wait until the camera has finished with any activity before making changes through the Conversion Circuitry.

NOTE: DS Substrobe Up-date may be required. DS50 Substrobes

• DS50 SubStrobes with a Serial Number below 63,850 can not be updated to operate with the eTTL Conversion Circuitry.

• DS50 SubStrobes with a Serial Number between 63,850 and 69,999 operate with the eTTL Conversion Circuitry, but require update to provide optimum performance.

• DS50 Substrobe with a Serial Number of 70,000 or higher or with one of the two following labels in the battery compartment provide optimum performance with the eTTL Conversion Circuitry.

DS125 Substrobes

• DS125 Substrobes with a Serial Number below 2,500must be updated to operate correctly with the eTTL Conversion Circuitry.

• DS125 Substrobes with a Serial Number between 2,501 and 4,900 operate with the eTTL Conversion Circuitry but require update to provide optimum performance.

• DS125 Substrobe with a Serial Number of 5,000 or higher or with one of the two following labels in the battery compartment provide optimum performance with the eTTL Conversion Circuitry.
