TN622 TX as Camera Trigger

It's a crap trigger (delay), I thought it was you who'd confirmed that to me (I thought mine was misbehaving)
 
I don't think it can receive and transmit at the same time, if that's what you are asking
 
Well, it works, but there's a 2 sec delay, because the 'test' fires the flashes but doesn't trip the shutter, the TX then waits a suitable time for the flashes to recharge then fires the shutter (which works).

My first post was easier to type, I could have sworn it was you :$
 
Are you trying to fire a remote camera with off camera flash?
 
I think this is better considered as two separate control systems, one for the shutter and the other for the lights. I have stacked a wireless shutter remote on top of a wireless trigger for studio strobes, in my case a Hama DCCS remote trigger on top of a Ojecoco H430 TX, it worked perfectly with no channel interference and avoided disturbing the camera for macro shots. The YN 622 TX doesn't have a top mounting but the YN622C transceiver does so I can't see any reason why this would not work without any apparent delay. The 622 TX could be used with the shutter remote velcroed to the tripod if necessary. I'll try it next time I do a macro shoot using the Yongnuos, which I also own.
 
There is something on the Yong...website that says this can be done. It gives instructions as to how to do it. I tried it but couldn't make moss nor sand of the instructions. Apparently written in Chinese and badly translated into English.

If I got it right it needs a 622 on the hot shoe wired to the camera and remotely controlled with the XT.

Never solved it but am interested if it can be done.
 
The best documentation for the YN622 series is 'The Other YN622 User Guide', it looks like the latest version is V4.10. Well written in english, not a translation and over 60 pages long.

It does indeed fire a test flash before focusing and then firing the shutter which would account for the long delay.
 
So, can you avoid the 2 flashes by holding the test button to focus?
 
How long is the delay in your test? Mine was appalling.

Can you explain your methodology for firing the camera using the 622tx? I'd love it to work, but had issues.
