Help connecting Radiopoppers to Dynalite M2000e pack

[ClickHappy]

I just got my Radiopoppers and went to hook them up to my Dynalite M2000e and I need to convert from a 3.5mm jack to the 3 prong AC sync plug. I have a two prong AC to 3.5mm adapter cable, but it won't fire the strobes. I'm guessing the third (middle) prong is the key here.

I have looked online and don't see anything at B&H or Adorama that looks like it will work.

Anyone know where to get either the 3 prong AC to 3.5mm cable or a female PC to 3.5mm adapter?

Thanks!

flashzebra might have something like that or you could as if they could make it for you

The middle prong does nothing. I have Dynalite M2000 and only the outer prongs are needed. In fact, I helped Flashzebra with a test of an adapter which he is marketing, to validate the ability of the two-connector H-prong to minijack adapter unit to trigger the Dynalite...it worked in both orientations of the H plug into the pack. (Some flashes like Norman can be sensitive to H-prong orientation!)

[ClickHappy]

Thanks for the info Wilt. I have the H prong, but it isn't firing. Tried both orientations and neither work. There doesn't appear to be loose connection anywhere, so I'm stumped. I'll take a pic of the wire in a bit in case it's a known cheapie that doesn't work reliably.

Just curious, is that adapter available yet? I didn't see anything like that on the site. Thanks!

It appears I have a mono plug and the ones that came with the poppers are stereo. Not sure if stereo is a requirement, but I'll pick up a mono to stereo adapter tomorrow and see if that does the trick.

Top is my sync cord, bottom is supplied extension cable.

Is there a way you can plug in the H prong, and then mechanically short the two contacts at the other end of the cord?

You'll need to ask Lon if he is offering 'the H prong adapter than Wilt tested for you' yet. I did the test for him a couple of months ago, if I recall.

[ClickHappy]

Yes, if I short them, it fires, so I know the cord is good. The poppers just can't make the connection with a mono plug it seems. If the mono to stereo adapter doesn't work I'll ask Lon about his adapter. Thanks!

I just pulled out the real Dynalite cord, the Flashzebra adapter, and a Flashzebra H cord and tested all with an ohmmeter. None have stereo plug, only mono.

On the real Dynalite cord, both the center blade and outer narrow blade(end where the cord comes out) is connected to the center pin (tip) of PC connector tip. The wide blade is connected to the outer surround (ring) of the PC connector tip.

On Flashzebra adapter, the blade labelled (+) is connected to the center contact of the jack, and the other blade (no difference in blade width) not labelled (-) is the outer surround contact of the jack.

On a two-pin H-connector-to-male miniplug (which I purchased from Flashzebra), the narrow blade connects to the center tip of the plug, and the wide blade connects to the shaft of the plug.
The H connector-to-miniplug works fine with my Cybersynch, plugged either direction into the Dynalite.

The Flashzebra H-connector-to-PC adapter works fine plugged either direction into the Dynalite.


When in doubt about electrical connection, verify mechanically the contact before you even think about connecting any electronic device (remote trigger receiver) as there can be electrical polarity issues between the two electronic devices.

Thanks again for taking the time to test and for the info.

Instead of continuing to guess at it, I'd rather get something that works. :) It appears this is what I want on the FlashZebra site, correct?

Lon's web site does not yet have the device which I tested for him...H-prong to Minijack adapter. The cord which you linked is the same cord which I had purchased from Lon to connect my Cybersync to the Dynalite. Your issue might still be Radiopopper!

[ClickHappy]

I emailed both Dynalite and Radiopopper to see what they recommend. I'll update with their responses. Thanks again for the info.

[ClickHappy]

Just a quick update. Dynalite said to check with Radiopopper. I expected as much, since it is a 3rd party system they have no control over.

Haven't heard back from RP yet.

In the pic the plug on the homebrew adapter cord looks short.

I am unsure if it is just the perspective fooling me or not.

The mono (two conductor) miniphone plug on the homebrew adapter should be the exact same length as the stereo (three conductor) miniphone plug on the cords supplied with the JrX set.

Enjoy! Lon

[ClickHappy]

It is a little shorter. I went by Radio Shack yesterday and all the mono jacks looked shorter than the stereo plug supplied. I'll go by again and see if I missed something.

In case I can't find anything, do you have an ETA for the sync cord Wilt is talking about?
Thanks!

Just came accros your plight. I am going through the same issue with my Dynalite 1000x pack. Tried everything. Don't know if there is some voltage issue? I am hoping now that the JrX have been out for awhile, someone will figure out an answer. Anyway, i don't have an answer . . . but i wanted to let you know that you are not alone!

Maybe this quote from another thread about Radiopoppers and 580EX might provide some clues...

"I quickly went to compatibility tests. The cable that comes with the radio poppers does not work with the Female hotshoe with miniphone jack from flash zebra, but it does work with the deluxe canon hotshoe with miniphone jack from flash zebra. I still need to buy 1/4in mono connectors so the receivers work with me strobes because the stereo adaptor doesn't work. As a note the products from flash zebra that work with pocket wizards and skyports also work with radio poppers. "

Has anyone figured out a solution to this yet?
