Yongnuo 622c-tx Super Sync Problem

[mike_wong5]

<p>Hello all,<br /><br />I'm having super syncing problems with my yn622c-tx. I just this along with a pair of the yn622c and can't seem to get it to super syncing when used together. Here's my setup:<br /><br />- 580ex II on a light stand attached to the yn622c. The flash is setup to hyper sync/super sync (as indicated with the "h" on the flash)<br />- yn622c-tx is on the hotshoe of my Canon 5D Mark III<br /><br />When in this combo, the camera will not let me take the shutter beyond 1/200. <br /><br />But, when I remove the 622c-tx from the hotshoe and replace it with another 622c on the hotshoe, the super sync works! I can go beyond 1/200 of a sec. So when I'm using two 622c, it works but when I'm using the 622c-tx to trigger the 622c, super sync does not work.<br /><br />Is there something that I'm missing or setting wrong? I can't seem to get this right. Does anyone with experience with these products know what might be wrong? Please help! Thanks!</p>

<p>Hi Mike,<br>

I have the exact set up with 550EX and mine works. Try resetting YN622C-TX. Hope that works.</p>

<p>Hey,<br>

I had the same problem. They fixed this exact issue in the latest firmware (get it on their site along with the firmware installation tool).<br>

Then connect your TX with a USB-mini (old type) cable which you hopefully have and run the Yongnuo tool to install the firmware.<br />In Windows 8/10 you may run into troubles because it doesn't find the drivers. But they included them, just search the folder where you installed the tool.</p>

<p>This is incorrect. The model of the YN622C that has a USB port for firmware updates is newer than one discussed in the original post. The YN622C II was introduced in June.</p>
