Ikelite 300D Installing the Port, To Remove Port, Port Seal Inside View, Using External Strobes

Installing the Port cont.

To prepare the port for installation, remove the port o’ring and lightly lubricate it. The port seal is a side-to-side seal and requires the o’ring to be lightly lubricated for easy installation. Put a small amount of lubricant on your fingers and draw the o’ring through your fingers to lightly lubricate it. Do not stretch the o’ring. Check that the lip of the port where the o’ring fits and the sealing surface on the housing are clean. Place the port, with o’ring into the housing’s port opening. Press down on the port firmly and evenly until you feel the port slide into place. Continue to push down on the port and push each port lock forward until it clicks into place. It may help to slightly rotate the port as you push in on the port lock. When the port lock clicks into place the Release Button will drop down against the port lock.

Check around the perimeter of the port seal to see that the o’ring is properly sealed and not extruded.

To Remove Port

To remove the port lift up on each Release Button and slide the port lock away from the port.

look on the inside of the housings at
the port seal. Check to see that the	Fig. 2

o’ring is properly sealed as shown in
figure 2.

Using the Conversion 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 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 Substrboe to TTL mode)

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.

The Consversion Circuitry also offers Manual exposure control with 3 1/2 f-stops of under-exposure control in 1/2 stop 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 12 for DS Substrobe compatibility with the Conversion Circuitry.
