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

[Basileus]

Being in a doubt what topic is more suitable for my fist posing on a board, 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 many people who suffer the same issue, I can provide a diagram of light output of camera strobe and
Sea & Sea strobe.




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.

hi Vasily

I have used the YS-110a with the E-PL1 in TTL mode and it worked well. Do you have the E-PL1 on "fill flash" mode? - Scott

Hi BluewaterPhoto,
yes in fill flash. As it required by S&S. The only FO cord is homemade from toslink cable. Works well in manual, even on 1/64. Waht camera firmware on your PL1? I've tested both 1.1 and 1.2.

Thanks.
