- What settings at the Inon Z240 are required for TTL mode with your converters?

The iTTL converter is targeted at developpers and producers of underwater photography equipment.
For immediate use, you should order the external converter.

For two (or more) strobes only one converter is required. Y-cables do work for all of our products. To achieve good TTL results, both strobes should be in the same power class, eg. YS60 with YS120 or DS-125 with Subtronic Mini.

The timing of the flash is not correct. All pictures are completely underexposed!

The TTL line of your strobe is not properly connected to the converter. What you see is the preflash. Due to the fact that the flash does a full dump (no TTL signal) the strobe is not ready for the mainflash a few milliseconds afterwards. The results are a black picture. Check continuity of all cables and make sure you have good contacts. The actual timing of the flash is not influenced from our converters at all!

What kind of sync cable is required for my strobe?

Sea&Sea YS90, YS120 and YS350 users need the "Sync Cord N for Sea & Sea Strobes (#17100)". Ikelite DS-series users need the "4104.6 Nikonos - to - One TTL SubStrobe". We do NOT sell these synccords. Any Ikelite or Sea&Sea dealer can provide you with the sync cords.

Can I use the OLY-TTL-C converter with the Olympus C5050 in the PT-015 housing?

No, the converter does not fit mechanically into the housing!

Problem: Olympus Converter with TTL evaluation doesn't work.

If you think that there is a problem with the converter or outside unit please read the following checklist carefully. It helps to isolate the error:

1. Converter: To test the converter unit, set the camera to SuperMacro mode and set the flash to external only. If the LCD of the C5050 is powered on and you can select the strobe (Or it's selected automatically), the converter is working and the camera excepts it.

2. Outside unit: Due to the encapsulated construction damages at the outside unit are not common. To test the outside unit take a picture with the INTERNAL strobe and hold outside unit with attached and powered external strobe in front of the internal strobe. The outside unit fires a low-power flash on the seconds flash as an error signal that the data packet could not be recognised (Because there was no real datapacket). The internal flash has to be disabled during normal use to avoid data transfer problems.

3. Transmission: The data packets are transmitted with an infrared beam. With optimal allignment the max. distance is about 10cm (4"). Old transmitters use a CR1225, newer use a CR1625 battery which has to be replaced after about 30-50hours of use. Old recievers and transmitters are cross-compatible with new versions.

General:

What settings at the Inon Z240 are required for TTL mode with your converters?

1. S-TTL or S-TTL LOW (Makes no difference)

2. Switch to "TTL"

3. Switch to "Normal"
