Multiple speedlites to one remote receiver???

[texshooter]

Is it possible to connect, say, three 580exii's to a single Cybersync or PW transiever? There's got to be a splitter cable to allow a gang of stropes to be fired from the same receiver trigger, so I don't need to dangle so many triggers on top of each other? But then maybe I need a reality check.

correct me if I'm wrong....
i think using a 580EX II, u can use 1 transmitter and a 580EX's receiver then the rest can be slaves of that 580EX that has a receiver...

Body (w/ transmitter)
580EX - A - Master ( w/ receiver )
580EX - B - Slave
580EX - C - Slave

You can safely split sync and feed multiple slaves from one trigger.

DYORD is correct - that'll work, but obviously not with the non-dedicated off camera manual flash units that a lot of people use for this stuff.

But yes, I believe you can split and use multiple flashes from one trigger. I know the cheap-o eBay ones can, and I see no reason why Cybersyncs or PWs can't. Nothing special going on, it's a simple switch/trigger - nothing that a split will affect.

Anybody know the make and model of such a splitter cable. To piggy back two speedlites, the splitter cord would have to have two PC connectors that each goes into the flash units and one 2.5mm male mono connector that goes into the trigger.

But wouldn't the electrical signal that is sent from the trigger up two separate cords to the flash units be weakened to the point of failure? I would think the signal might become delayed.

Hermes has successfully split sync numerous times. He used something like this:

The plug is connected to the sync jack of the trigger. Then you use miniphone to Nikon screw lock cables to connect the individual jacks on the splitter to the flashes.

If you want to look into this further you can check out the thread Hermes had started:

That Belkin splitter looks amazing. I'll have to pick one up.

They have PC cord splitters as well if you are useing a PC cord.

If you want to do it with wire, you could use the splitter below, it uses 3.5mm and you coulod connect five flashes to it using one trigger and using more for more splitters. I have the same setup inspired by Hermes and tested it with out three flashes and it works, Hermes has also done the same here and confirmed it worked too.. So, see the link below, it's only $13.99 but you need to buy five more 3.5mm to 3.5mm long cables:

Does anyone know if this is possible to do with a PW FlexTT5 and retain ETTL, at a reasonable cost? I found a cord to do so on Amazon but it was only 30 or 40 less than a new PW transmitter.

I think the only thing you have to worry about is length. With standard receivers all it is, is a simple on signal short and to the point. However the longer each of the runs, and the more times you split it, the less power is going to be going to each receiving station.

I would think, though have not tested it, that the Flex doing ETTL, actually talks to the flash and is more than just a trigger.

I am probably being a pessimist here but is there a concern about the amperage going through the remote receiver? I know most of the flashes are the nice 6v or below ones, but if they are wired in parallel the amperage will be higher and more for the trigger to switch. I don't know what kind of switch or scr they use though.

Edit: looks like the other post did take a look at that issue seems fine O.o

Yes

No.

I am probably being a pessimist too, but why would you wanna buy a set of PW if you're just gonna use cords for the others? I would use the ETTL method.

[photobitz]

I assume the idea is to trigger a group of flashes in one place creating a larger burst eg. to counter the sun. No point using more than one PW for that sort of thing. It then leaves you with spare PWs for other flashes in your setup...

Why ETTL?
