The ETTL converter is only available as an OEM modul and was developed for housing and strobe manufactures. The following connections are required:

• a 6-wired cable from the existing strobe connector to the converter module. An optional strobe connector is available if your housing wasn't supplied with one.
• a 3-wired cable to the strobe bulkhead(s).

A universal (open drain) output for focus-assist lamps is available and will be activated to help the camera focus in low-light situations. Technical description of the AF output on demand.

All required connections are discribed in the supplied and detailed manual. The unit was intentionally made for strobe and housing manufactures but individuals will be able to install the units, as well. (If you can use a soldering iron).

ETTL is a very complex protocol and requires a special preflash (modulated "linear preflash") which common underwater strobes cannot reproduce. This converter fires a normal preflash and because of very exact timings the results are accurate. Even in mixed light situations.

Please note the following facts:

• ETTL-highspeed sync is not supported, min. shutter is 1/200sec
• The battery (type CR2032) will last for 100 to 200 hours. A power saving st By mode will be activated if the external strobe is set to OFF. Battery will last for at least 2 years in st.By.
• Camera uses more than 150 power levels for the strobe
• to compensate little differences of the strobes a potentiometer is included. An external potentiometer will allow flash exposure compensation settings. The connection of the external components is described in the manual.
• connectors with pigtails (~25cm) are supplied
