Seacam and Inon 240's

Hello all,

I have a Seacam D200 setup. I have 2 Inon 220's / 2 240's and Quad and finally Seacam 350 Megablasters.

I always check my strobes with my Gossen light meter and it appears that I cannot seem to get the proper protocol. I started with my 220's which I used with my F100 without a single problem. Thinking that the digital electronics in the D200 was my problem, I "upgraded to the 240's. Still the same problems.

All cables and strobes work as they should by themselves-individually.

Hook up left bulkhead with 240 works fine-when the right side bulkhead is hooked up it works fine but now the left side only will fire at minimum now matter whether on full or manual stops. Right side strobe functions whether on not the left side strobe is connected.

I have seen the Seacam Tech notes and tried these tests with 1/2/and 3 pins removed.

With the 2 leftside pins removed, with right side strobe turned on ,the left side fires at 1 stop greater than minimum no matter what the strobe power setting is at. If I turn the right side strobe off, left side goes back to minimum.

With center pin only. Right side strobe fires at minimum whether right side strobe is on or off. If I unplug the left side strobe the right strobe will not fire at all.

Just writing these results gives me a headache, let alone trying to figure out the proper protocol. Does anyone have these setups that has figured it out? I have not tried all of these combo's with the supplied Inon bulkhead filters but I tried 1 or two and they made no difference.

Without ttl and shooting in manual-when I want full on 1 strobe and half power on the other then that is what I should get. Thank you in advance,Wayne

I have The D2X Seacam and dual Z240'S. My wife has the same setup but uses Seacam 90 Autos. The left bulkhead comes wired with 5 wires for iTTL from the factory while the right has 3 wires for Nikon manual protocol. When shooting manual, we pull the 1 and 4 pins, see: ( Wetpixel Nikon D2X Hotshoe syndrome and fix ) for the diagram. The 1 pin is lower right and the 4 pin is upper right. We use both bulkheads for manual and replace the pins for iTTL using the left bulkhead with the Sea and Sea iTTL converter ii. All seems to work well, but I have never tested with a light meter. Hope this helps. Check with Steven Frink if still a problem.
