YONGNUO – YN-622C and YN-622C-TX Updates

YN560-TX to YN-622C


YongNuo have quietly updated YN-622C, YN-622C-TX, and YN-E3-RT triggers manufactured from December 15th 2014.

As well as improved stability, YN-622C used as receivers will now provide direct compatibility with the remote manual YN560-TX transmitter units.


The YN-622C-TX have also received a revised printed circuit board which is reported to increase their working range to match the original YN-622C units (up from around half of the range previously) .

Upgrades to the YN-E3-RT are not clear as yet, though they may hopefully provide similar improvements.




YN560-TX to YN-622C


The latest YN-622C used as receivers will now provide direct compatibility with the remote manual YN560-TX transmitter units.

This allows a YN560-TX transmitter to control the manual power levels and flash zoom of both YN-560 III and YN560 IV flashes, AND now other ETTL flashes mounted on YN-622C receivers as well.

To enable this YN560-TX compatible mode on the latest YN-622C, simply hold down the Channel (CH) button while switching the YN-622C on, and the status LED will turn to orange.

Although I have not confirmed this yet, this new compatibility should also allow the YN300W studio lights to also be controlled with remote manual power levels via the YN560-TX.

Also while combining the speedlites as before if desired.




So YongNuo have now managed to pull back some important compatibility between their otherwise separate systems.

This compatibility is still only in one direction though, when most people would likely prefer to be combining the YN-560 III and YN560 IV flashes with their YN-622C-TX as the transmitter. As this provides extra features like ETTL in some groups, as well as Second Curtain Sync, and an AF assist light etc.

So at this stage at least there is still unfortunately no direct radio compatibility or remote control between the YN-622C-TX and YN-560 III / IV flash units.




To YongNuo’s credit though, either system (or transmitter) can at least operate in remote manual on any camera with a standard hotshoe.


NOTE – YN560-TX to YN-622C compatibility has actually been available previously to some degree, though this required a more complex work around, using a YN-622C-TX as well to relay the signals from the YN560-TX to the YN-622C receivers. A special Proxy Mode was added to the YN-622C-TX to allow for this.






Since the original YN-622C-TX were released they have unfortunately suffered from range limitations of around half that of the standard YN-622C transceivers.

So the YN-662C-TX have now received a revised printed circuit board design which should reportedly resolve this issue. As well as providing improved stability again.

The YN-622C-TX provide a major upgrade in features and convenience to the YN-622C system, so if all goes well the new transmitter should be a significant step forward for the system.


Upgrades to the YN-E3-RT transmitter are not clear as yet, though they may hopefully provide similar improvements.




The upgraded triggers started production from December 15th 2014. So all units marked from January 2015 onward should safely be upgraded units.

There is usually a sticker in the battery compartment which shows the month and year of manufacture.


UPDATE  – The official YongNuo Ebay Store, and official YongNuo Amazon Store are now selling the updated YN-622C.
