The sync works great. I can also use the port to trip my cybersync transmitter to trigger both on &amp; off camera flashes without hooking the cybersync to the PC port on the camera.<br /><br />Ivan-<br />I somehow ended up with the same issue as you. The slave switch now does nothing... it is stuck as master &amp; won&#39;t switch to off. Everything still works fine, but I&#39;d like to get it switched back off to get rid of the icon on the lcd. You say you played with it until you got it switched. What exactly did you do?

It seems when I placed the shoe back in, I damaged the Master/Slave selector. I played around until I got the Master switch selected. It works perfect now for the exception that I cant select Master or Slave using the IR function. Not that I care for that feature anyways. So for anyone caring to do this mod take your time placing it back in. Ive done another mod with this in mind and everything worked out perfectly.

I've seen odd behavior in two situations.<BR/><BR/>1. Plug not fully inserted - especially when using a stereo cable.<BR/><BR/>2. Trying to use the sync port while the flash is mounted on-camera. <BR/><BR/>The fix for #1 is obvious; my workaround for #2 is to use the PC connector on my camera body instead of the one on the flash... The point of the on-flash sync port is exclusively meant for off-camera usage. However, I've tried to use it (unsuccessfully) to trigger a pocketwizard (which then triggers room strobes; the 580 on-camera provides a bit of fill). Like I said - just using the camera's sync port is a fine workaround here.<BR/><BR/>Beyond that I'm not sure I can help. If you provide some more info on the exact setup maybe someone will have an idea.Ryan R.

Thanks for sharing! I have a couple of 580ex speedlights and want to do the mod as well... I have a question though. Can i trigger my flash off cam with this mod? Because from the way i understand that you use it, it looks like the 580 is triggering your PW to trigger the rest of your PWs. Did i get that right?<BR/><BR/>Thanks!<BR/><BR/>-MarkMarkyhttp://www.blogger.com/profile/07639466482342919042noreply@blogger.comtag:blogger.com,1999:blog-21546207.post-54813486147281650522008-08-29T12:12:00.000-04:002008-08-29T12:12:00.000-04:00IMHO, if you are concerned about current direction in 580 jack, you can put a diode to limit current flow only in one direction.<BR/><BR/>Thanks for sharing, very helpful mod.<BR/><BR/>GuarapolLuishttp://www.blogger.com/profile/02978990467965813736noreply@blogger.comtag:blogger.com,1999:blog-21546207.post-63001684500773839452008-06-15T11:25:00.000-04:002008-06-15T11:25:00.000-04:00Svavar -<BR/><BR/>The info provided is educational only and is not provided or verified by Canon; anything you do to mod your flash is at your own risk.<BR/><BR/>With that out of the way... I use the modded flash on-camera all the time with no issue! If you think about the setup, you aren't really changing anything so long as nothing is plugged into the new jack. <BR/><BR/>I often have the 580 on-camera and use the pocket wizards to trigger other flashes throughout the room. I keep the 580 turned down a bit so that it only provides a little fill - this lets me get some nice quality of light but allows me to capture a shot from any angle in the room... even if the subject isn't really in the "right" location with regard to the room lights. In other words, the 580 provides some fill & acts as a sort-of safety that ensures I'll have a usable shot (albeit one that may need some heavier tweaking in the post processing stage).<BR/><BR/>I'm typically triggering the pocket wizard in this scenario via the PC port on my camera body - not the port I've added to the 580. Why? No real reason in particular, though you need to be slightly more careful as to how your PW is set up if you're going to use the 580 jack: if the PW is set to trigger "local" or "both" instead of just "transmit" the pulse fed back into the 580 can cause it to get confused... turning it off and back on fixes the issue, but it'll typically blast full-power flashes even in TTL mode until you stop the PW from sending the trigger pulse back into the flash.Ryan R.

Just wanted to tell everyone with a 550 or 430 and need some extra space, that they can easily place a "female" jack on the outside. This way the jack dangles on the outside of the flash, but does that really matter? Use some shielded cable, and tie a knot on the inside of the flash shoe, so you don't pull the soldered cable out of it. Use a different type of jack, the ones that aren't meant to sit inside a box, but are used in extensions etc.Larshttp://www.blogger.com/profile/03599264878067536363noreply@blogger.comtag:blogger.com,1999:blog-21546207.post-87096096827355247692008-02-09T07:46:00.000-05:002008-02-09T07:46:00.000-05:00christiansahm: Sorry, but I don't have a 550 or 430 to play with. I've got the 580 & the rest are Nikon flashes - for the simple reason that they have PC connections built in. Just easier for what I'm doing with them.<BR/><BR/>Anyway, you may want to contact Lon over at <A HREF="http://flashzebra.com" REL="nofollow" TITLE="Flash Zebra small flash gear connectors">FlashZebra</A> and see if he has any suggestions on how to mod these flashes. He may also have some kind of triggering cable / connector that'll work with your stock set up.Ryan R.

I did not give up yet but it would be nice to know if anyone already modded a 550 or 430 and maybe can show some pictures to where placing the jack is possible...?christiansahmhttp://www.blogger.com/profile/17057021967423447515noreply@blogger.comtag:blogger.com,1999:blog-21546207.post-24313931046999577872008-02-07T20:42:00.000-05:002008-02-07T20:42:00.000-05:00Great Post!!!

This should work for the 430 and more or less any other hotshoe flash... The key is the center pin & the ground - the rest of the pins aren't needed to fire the flash (at least in the Canon and Nikon worlds).<BR/><BR/>Let us know if you run into any quirks modding your 430.Ryan R.

I likely makes no difference, but I did it just in case an oddly-fit cable were inserted in such a way that it wasn't making contact properly.<BR/><BR/>Glad you enjoyed the tutorial!Ryan R.

The jack I bought from Radio Shack was different from the one posted here - The long lead was for the tip and the short lead was for the sheath. I found this out after I had soldered everything and all the buttons on my flash stopped working. Switch the wires around and it works perfectly. Also, I can't figure out why you have the tiny U shape wire connecting two already conntect parts (the tip and lead for it). I only soldered the lead and it worked fine. Mine may have been a different jack setup though.<BR/><BR/>Other than that, great tutorial!Anonymousnoreply@blogger.com
