E-PL1 and 110a DS-TTL out of sync

Being in a doubt what topic is more suitable for this post, decided to drop in here as a separate thread.

My question (=problem) is about 110a DS-TTL sync with PT-EP01 via optical cord.

And as far as I understand my problem is not unique and it is a "out of sync" problem. DS-TTL is not working.

Unlike a people who suffer the same issue, I can provide a diagram of light output of camera strobe and

Sea & Sea strobe. See attached.

graph on the up (of each image) is a S&S output TTL - slave full output, graph below – E-PL1 strobe. Forced flash.

Unfortunately, here in Russia I have no official S&S support, so I cant use an official service. Suspect

some strobe malfunction, or E-PL1 is not compatible with 110a in fact.

Comments and/or advices, especially from Sea&Sea reps would be much appreciated.

I will take a wag and suggest your strobe is firing on the pre flash.

definitely it looks like, but where is a DS-TTL "mimics"? assume there is a false triggered action on zero point on the gpaph of PL1 strobe, possibly caused by sensor overloading as a reason of short FO cord and high level of light. Here the graphs with "attenuated" FO cord. Winth a different level of attenuation.First - a high, second - low attenuation.
