Would this be a working RF-603 setup?

Hello peeps,

a question before I go about ordering all sorts of PC sync cables. I'm wondering if this could work:

The yellow things are the flashes
The green ones are the 603's
The cyan lines are PC sync cables
The one black cable running from camera to the RF-603 on top is the trigger cable.

what flashes are you using buddy? Also if you place a 603 on top of the camera and run the shutter lead from the 603 to the camera. When you press the hand held trigger it should trigger both the 603's that are connect to the flash guns and also the shutter release. You shouldn't need the pc flash sync cable the goes from the hot shoe to the flash on the right as the 603 its mounted on should fire that one with the need for the lead.

Do any of you 4 flash guns have an optical slave function because if they do, I would be inclined to use that one where you have a flash gun but no 603.

Should work if I have understood you drawing.

I'd be using YN-560's.

Ok fair enough. Stupid on my side, but what about if the pc-cord would run directly into the flash?

I guess the thing I'm asking is: Would all 4 methods of triggering really work?

And I'm not really up to date on what optical slaves are. Is that the infrared thing, because that's really cumbersome init?

Well you YN-560 does have a sync port should work find from the pc cable. All 4 methods should work fine buddy, although if you need that much light (Unless you are getting all artistic) maybe look at other portable options.

What you have illustrated will work in a round about way but without getting my gear out and trying different methods it's difficult to be 100% sure of the results.

Well, I wasn't planning on using a 4 light-setup. I'm just looking at my options here. Wondering what I could use and what would be the nicest.
What would be other portable options? I was thinking of buying a reflector and putting that on the other side of whatever I'm shooting, so I'd need 'only' two lights instead of three, could that work when shooting through an umbrella?

Yes it would, I have a small soft box with a flash gun bracket that works well and I think would serve you well.
This is the one I have, cheap and cheerful but it works

As you can see there's 4 flashes:
1: Triggered wireless by the 603 on top (I presume this one works)
2: One flash on top of the camera (Ibidem, this works right?)
3: Triggered by the PC-Synch cord running from the transceiving 603 on top to either another 603 or directly to the flash, shouldn't matter I guess. (not 100% sure about this one, but I guess it works...?)
4: This the one I wouldn't know: The flash triggered by the pc-synch cord running from the camera directly into the flash. It follows a pretty long path: Trigger > 603 on top > cable into camera > pc cord to flash

Thanks in advance!

Unless the RF-603 transceivers can automatically switch from Rx mode to Tx mode like the PW transceivers can (I couldn't determine that from the RF-603 manual), you will need one 603 as a Rx unit connected to the camera remote release port to trigger the camera and another 603 as a Tx unit sitting in the camera hotshoe to trigger the remote flashes. And these two units will need to be on 2 different channels to prevent interference with each other. Then, your handheld 603 Tx unit to trigger the camera needs to be set to the channel the camera Rx unit is set to and the 603 Rx units for the remote flashes need to be set to the channel the camera Tx unit is set to.

If all the Rx units are set to the same channel, the camera and flashes will be triggered simultaneously and because of the shutter lag of the camera, what's going to end up happening is the flashes will fire before the camera shutters have even opened up completely and the flashes will not sync up with the camera.

Rx and Rt channels?

I don't own RF 603 triggers. (I do own RF 602's) I do not think your block diagram is going to work in the way you want it to. If you want to remotely trigger the camera, you will need a RF603 on the remote trigger port and another on the hotshoe to fire your flashes (and one in your hand). There was a good post illustrating the set up quite a while ago. Here is the link:

Sorry. Tx = Transmit or transmitter. Rx = Receive or receiver.

The diagram on page 2 sure does! Very helpful.
So basically I would need another set for that to work. One set to trigger it, one set to flash everything.
This opens up new perspectives.

New scenario

I have a wired shutter trigger plugged into my camera. I also have a 603 mounted on top of my camera.
Let's say I have a 4-flash setup:
1: Mounted on top of the 603, which is mounted on the hotshoe from the camera
2: Mounted on a 603 somewhere on a lightstand
3: Connected by PC-cord running from the 603 on the camera (directly into it)
4: Connected by Pc-cord running from the camera to the flash (directly into it)

Would all these 4 combinations work then? Because I don't really need wireless triggering as I already have a wired shutter trigger that works just fine and is long enough for what I want...

In the latest scenario you have posted, here are my thoughts:

I believe items 1 and 2 will work for sure
I believe items 3 and 4 will also work,

It should be easy to attach a flash to an RF603 and run a sync cord to another flash to test the scenario.(two flashes firing from one RF603)

Hope this helps,

Thanks.
I'm just wondering if both PC-sync cords would have an output signal. Both the on-camera one and the on-603 one.
Oh, and then of course there's ANOTHER 603: the one triggered wirelessly by transmitter. Does that one have an output signal?

That makes for a total of 5 flashes that could possibly fire from 2 603's. Hmm, maybe I should just get a cord and see for myself. They're 5 bucks for 1 meter and 11 bucks for 5 meters. The latter might be a little long though...

I did a quick test with my RF602 triggers to see if two flashes would fire from one receiver. I placed a Canon 580 EX in the hot shoe of the receiver and ran a sync cord to a Alien Bee 800 (from the same RX unit). Both flash units triggered when I pressed the button on the transmitter...It looks like it works, but I can not comment on what the maximum cable length might be. I would not go off the deep end with an extremely long sync cable. The inductance of the cable can not do you any good.

Ok, that's good to know! Thanks a lot!
And the Sync cable that runs from the camera itself, that one works as well right?

And what would you call 'extremely long'?
