DS125 Problems

Hello,

I have got a DS215 strobe that I used to use with my 300D Ikelite housing with an EV controller. This worked perfectly well.

I now have a 350D housing with the new Ikelite housing with TTL circuitry. The problem is that the strobe refuses to work when the strobe is set to TTL. It works fine when the strobe is set to FULL or any other setting. I have checked that the setting on the underside of the housing is set to DS125 too.

When I turn the strobe and camera on and set the strobe to TTL the strobe emits a constant bleep-bleep-bleep sound and will not stop until I set the strobe to FULL.

The strobe serial number is 3367 so as far as I know it should work with the Ikelite TTL electronics.

Has anyone else had this problem or know what it is? Any help would be greatfully received as I am going to Western Australia diving in 10 days!

Thanks,

Rob

I have just checked another post and this problem may point to the sync cord. I am using the one I used for the old ev controller - it has a black ribbon on it.

Aparantly the new ones have a blue ribbon round them.

The strobe also now seems to fire when I take a picture - but a very small flash. It then reverts back to the constant bleeping....

Sounds like you solved the problem yourself. Yes you do need the blue band sync cord for TTL.

See the URL for this housing http://www.ikelite.com/web_pages/2dslr_300d.html then click on eTTL link between photos on left column on that page. Strobes before 5000 serial number require update to operate properly, besides needing the correct sync cord. We can probably make your trip deadline if you send it to us via next day service............

Fixed! I got the blue cable and it works perfectly.

Thanks everyone.

The eTTL exposure may not be exactly right because your older strobe is sending audible ready light and confidence signals for four seconds as per old Nikonos protocal. This interferes with digital camera/strobe communication. Keeping your pictures ten seconds apart should produce uniform results that can be corrected by flash compensation. Strobes should be returned for updating as per the URL above.
