D2X Flash Issues

Hi Robert, I just found out that covering the pin indicated at the Ikelite site that I mentioned won't solve your problem. For the solution, check here:

Dave, thanks for the instructions!

Luiz, nice job illustrating my instructions. Hopefully this will help ease the nerves of the "tool weary".

That's great work Dave and Luiz. Thanks for posting.

Luiz,

 

This is amazing. Yesterday I was stumped by the D2X-Subal-strobe wiring problem, and fairly sure (and I was correct in this) that I didn't really understand what was going on even after reading the posts on the topic to date. A few posts later, returning to check wetpixel after dinner, I knew I already had enough information to proceed and probably get it resolved. Then I wake up this morning and to find detailed color photos and instructions from Luis showing exactly what I must do and how to do it - and without having to cut the green wire. (The bystanders on the movie set are all relieved).

 

Reiterating what I posted in response to Luiz's instructions on the DIY thread: this

 

man is a gentleman and a scholar.

 

Just to sum up what I think I might now vaguely understand, what the Subal manual should have told us was that:

 

1. The two sets of internal strobe wiring can be switched from four-pin female connectors to the three-pin connectors.

 

2. For use with housed Nikon strobes (e.g, SB800), the strobe wires should be left in the 4-pin connectors;

 

3. Replacing the strobe wiring in the 3-pin connectors defeats the "monitor contact" pin and may be necessary (and sufficient?) for use with some strobes (i.e., Ikelite) in manual mode..

 

4. With other strobes (e.g., Sea&Sea, Inon, SubStrobe, ???) it is also necessary to defeat the "ready light" pin, which can be accomplished by removing the pin from the hotshoe or cutting the green wire.

 

Does this make sense?

 

Thanks again all - Alex, David, uwphoto tech, ssra30, and especially Luiz - for all the help.

No problem Robert, that's what we are here for! And yes, you are right about your four points above. The only thing is that everybody calls it a five-pin or five wire connection (four pins + the ground contact), but the hotshoe does have only four pins plus ground.

I'm very impressed. Switching the internal connectors from the five-pin banks to the three-pin banks and removing the spring-loaded pin from the hotshoe connector took all of ten minutes. Better yet, I managed to do all this without tearing up the plastic bank connectors in the housing OR stripping the threads or the slots on top of any of the screws, or losing any bits and pieces.

 

Best of all, it works! Both the new Inon D2000w's and my Sea&Sea YS90DX's worked fine in manual mode. A friend will be carrying my SS200s back from the US next week, so I'll be able to test and hopefully use those as well.

 

(The Nikonos synch cords (single and double) for the new Inons are the same ones used by Sea&Sea, by the way, so anyone who is interested in these strobes who already has as much synch cord redundancy as they think they need, you won't need to buy new cables.)

 

At full dump, the new Inons didn't seem to have as much oomph as the YS90DX strobes, but I may not be setting the controls correctly. Just looking at the test shot images on the back of the camera, the color temperature of the Inons seems considerably cooler than the YS90DXs.

 

Thanks to all again. I hope to get the rig in the water for a few days around Xmas.

Luiz, thanks for a very nice graphic demo for the tooling challenge

Luckily my next strobe would be a DS200 so hopefully my subal will still requires no fidgeting on my part btw my Subal dealer banned me from having a screwdriver within 5 ft of the housing or else the housing warranty would be void!

First sorry for my bad english

 

Ok, today arrived from Seacam the D2X housing, WITHOUT the pin n. 1 (see the photo below)

 

 

I connected my two Sea&Seea YS120, and they fired, BUT no photo on memory card! Ok, removed also the pin n. 4 (as recommended from Seacam http://seacamusa.com/d2x-hotshoe.shtml the same!

 

The solution (adopted last summer with a Nikon D70 and Fantasea housing): replaced pin n. 1 and 4, then removed pin n. 3 (see the photo below)

 

 

The flashes fired and finally the photo was on memory card.

 

The comment? NO COMMENT!!!

Hi Passanisi,

 

You pointed out something that I haven't noticed before. The recommendation on the Seacam page works for some but not all strobes, you correctly removed pin 3 which corresponds to the ready light pin. See this page with a recommendation identical to what you did (but using a Subal hotshoe):

And here is more info on the Nikon hotshoe:

You should also remove pin number 1 and 4 if the Seacam has a 5 wire connection to the strobe. I will point this out to the Seacam people.

 

Thanks,

 

Luiz

Thank Luiz!

 

Another fact: the same day, the identical housing was received by my friend. He uses the same flashes (two Sea&Sea 120), and with the pin n. 1 removed, all works right for him!

 

A good story for the X-Files, right?

 

Best regards

No problem Marco, I am glad we could help. Thanks to you for pointing it out too, now the following notes were added to the Seacam page and wetpixel article:

 

Note #1 - The factory configuration with all pins is necessary for i-TTL utilizing Systemflash with Nikon speedlights and Seacam Seaflash 250.

 

Note #2 - IMPORTANT - When you add a second flash, we recommend you remove the pins in the 1 + 3 + 4 positions. You will, however, lose the ready light signal in the camera's viewfinder from the main flash. Images will write reliably to card this way though, so the tradeoff is reasonable.

 

Here is a link to the wetpixel article:

EDIT: There is a new article with detailed instructions from Seacam about this subject:

Ive seen this problem now also. We have 6 YS90DX strobes and sofar ive never had any problems. Until yesterday. Same issue, image doesnt write sometimes. Ive switched to two older strobes and sofar didnt see the problem anymore. I think one of the strobes is a bit newer than the rest, and that one is probably causing the problems, which would suggest some circuitry changes have been made..?

Undoubtably the problem is with newer circuits. I used 4 different YS 120s and never saw this problem until I bought 2 new 120s late last year.

Julie just got her Subal ND2 and it looks like Subal has addressed this issue. The strobe connector now comes with only 1 contact, and a little bag of extra contacts you can add if you need them.

D2X flash quirks

 

I set up my new D2X in an Aquatica housing and was surprised to find out the the housing hot shoe connector only had two pins and the offset one didn't look like it was in the roght position for contact. I get no ready light information in the viewfinder, and I was wondering if this was done intentionally or a defect. Anybody have similar issues?

 

Steve Simonsen

[Rocha 0]

Steve, I think this was done intentionally. The modifications that we discuss above also turn the ready light off. The D2x doesn't fire when it receives ready light signal from two wired flashes, that's where all problems come from.

 

Take a look at this topic for a more detailed explanation:

Luiz, whats interesting is that in the current ND2 housings Subal only connects the trigger pin. The ready light is disconnected (obviously) but also the TTL and Monitor. At least now I dont have to disconnect mine Julie can use the newer strobes that are interacting badly with the D2x
