NJphotodoc Loc: Now in the First State

Here's the problem that hopefully someone can resolve.
I purchased the Yongnuo 662N transceivers and the 622N TX transmitter. Camera is a D-7000 and my 2 flashes are a SB-600 and SB-700.
When used directly with the D7000 in both normal and Commander mode, there are absolutely no problems.
When I put either flash onto the 622N in passthrough or remote, the unit will fire at full power once before the shutter actually opens (you can see/hear the time difference). The same problem happens when I use the 622n_TX to trigger the 622N. Push the shutter button and both flashes will fire before the shutter opens. Result- any picture taken is black.
I've tried these in iTTL and manual- same result. The D-7000 is set to FP (tried both 150 and 320). Even did a factory reset of the D-7000 just in case that was the problem. Flash on camera is fine. Use a 622N and it all falls apart.
Don't want to have to move up to a Phottix or Pocket Wizard but may have no choice. Any suggestions would be greatly appreciated. If not, these go back for a refund.
THANKS

This is a long shot.....Maybe your camera is set to rear curtain sync.

If you just received your trigger/transceivers and trying to understand the user manuals you may want to check out a couple of videos by those that have already done so.

The first 2 minute video shows basic setup for the 622n. If you already know how to change the 622n from ttl to manual mode and back, then you can skip the first video as everything else is repeated in the second.

The second more detailed video includes more information on the 622tx and demos the setup and use.

Right now the camera is set in FP mode. Tried all different settings including S,P,M and A. Results are all the same. Push the shutter button half way and the flash goes off, then the shutter engages.
When I heard from YongNuo, they said it the iTTL and is normal. Clearly, it's not.

Thanks for sharing. Will look at these and see if they offer any clues as to how to fix this.

Wish I could help. I have the YN-622n and YN622n TX system with a SB-600, SB-800, and 2 Meike 910 (SB-910 knock offs) and the system works flawlessly.

I will try to mess around with them tonight after my scheduled shoot to see if I can reproduce your problem.

Thanks. Problem is that both flashes (SB600 and SB600) trigger before the shutter is actually open in either remote or pass through. Did a complete reset for both the flashes and the D-7000.
Camera and flash are fine when coupled directly to the hot shoe. Put a 622N in the mix and it all falls apart. Even wrote to Yongnuo and their answer was to buy another camera and see if that fixes the problem!
If I can't get it resolved, will probably just bite the bullet, send the Yongnou stuff back for refund and get the Phottix Odin system. Nice but > 2x the price of the Yongnuo.
I'm flying out this Friday to shoot a friend's wedding in Guadeloupe (beachfront wedding at sunset) so don't want any unplanned glitches. Tried CLS just in case but the infrared coupling is not fantastic outside past 10'.
Any advice is gladly accepted.

Don't forget that Yongnuo suggests the first thing you do is upgrade the firmware before you do anything.

After reading all the problems and issues with the Yongnuo (triggering, flash output, etc.) decided to send these back, save up and get the Phottix Odin system. Looks to be > double the price but at least I know it will work.

Thanks to all for your suggestions and did follow your advice but the triggering problems persist and I don't have any confidence in these units. Might work well with Canon, but there's a lot of work Yongnuo needs to do to get these to work consistently with Nikon.

I hoped you had resolved your problem by now. Sorry you had issues with your copy of the system, but others have used the system with Nikon and find it a cost effective product.

I just received my new 622n-tx. Initial tests with my Nikon D7000, SB700, and YN-565ex are satisfactory. Before I got the "tx" I used multiple 622n transceivers when I wanted either TTL or HSS off camera.

The settings that worked for me are when I wanted off camera HSS or TTL with SB700 and D7000 were:

1.) both 622n transceivers set to Channel 1 Grp A and TTL mode (green indicator).
2.) one 622n on camera, other on SB700.
3.) SB700 off camera set to "TTL" on selector and Off/On in simply "On" position.
4.) D7000 custom menu function e1 auto FP 1/250.
5.) I normally shoot in Manual mode when using flash.
6.) I adjusted flash output by holding the flash button on the D7000 and adjusting FEC up or down. The 622n passed that info to the SB700.

If I wanted to use pass thru commands from the SB700 to another Nikon TTL compatible flash (in my case the YN565ex) for manual adjustments step 1 was the same.

2.) 622n on camera, SB700 on top of camera mounted 622n.
3.) SB700 TTL selector in "M" position.
4) SB700 On/Off in "Master" position.
5) YN565ex set to TTL mode and placed on top of 2nd 622n.
6) Make adjustments as desired to Grp A channel 1 on SB700 and the 622n transmits those adjustments to the remote flash.

Remote flashes are always in "TTL" mode with the 622n even when they are being adjusted and used manually.

The new "tx" makes it even easier to adjust off camera flash from the controller, and eliminates the need to have a bulky master flash on top of the camera.

I hope that you find the Phottix system meets your personal needs.

I don't see any mention of this on this older thread, but I wonder if camera "Pre-flashes" were triggering the receivers too early.
