 YN-622N-TX -

The much awaited YN-622N-TX transmitter (for use with the YN-622 TTL triggers) are reportedly still undergoing testing, and will likely available in the new year now.

The YN-E3-RT (and coming YN-600EX-RT flash) are not directly compatible with the YN-622C TTL triggers, or manual RF-602/603/YN-560 III systems.


Separate Receivers -

UPDATE – YongNuo have now released the YNE3-RX receiver units to accommodate other MK II style Canon or YongNuo TTL flashes.






Updating Firmware -


Firmware download links are found at the bottom of the page here –



A number of firmware versions have been released since the YN-E3-RT was first released. These updates resolve a number of bugs and also add some features.

You can check the firmware version in Menu 4 on the transmitter to see if its up to date with the latest version. If not, its generally a good idea to update.

The update software is currently for Windows only.

You need to download both of the links – “Driver & Software:” and “Firmware v1.XX:

Unzip both packages to a folder on your computer (for windows Vista and later – right click on the folder, and “Extract All”)

    That was quick, the Yongnuo site has firmware 1.20 on the site. Change log reports:

    2015.12.03 v1.20:

    Fixed: Some LCD screen won’t display after waking up.

    I have not upgraded to either 1.19 or 1.20 yet

    Yongnuo has resently updated the hardware and firmware prior to V1.18 (as I recall) will not work on the new hardware. I think that the change you mention is that update. Yongnuo can only perform firmware updates on Windows PC’s. I only have a Mac and a PC running Linux so I’m in trouble if I need to update the firmware. Pixel firmware update work directly under Linux. Much better!

    I have the a Canon 60D, Canon 600EX-RT and YN-E3-RT.
    I want to buy another flash (manual is good enough, no need for ETTL, etc), but I’m not sure which flash models are compatible so that both existing (600EX-RT) AND new flash will both work AND BE CONTROLLED at the same time by the YN-E3-RT.

    Any help or direction would be appreciated.

    Thank you :)

      Hi David,

      The YN600EX-RT are really the main option still. They have full TTL and HSS etc as well as remote manual power control, though for $110 its hard to complain.

      The other option (apart from genuine Canon RT flashes) would be using other ETTL flashes with a YNE3-RX receiver attached. That’s not really going to be any more economical though unless you already have access to a good compatible flash.

        Hi! I am using the e3-rt with the YN600 flash currently and wanted to know if the e3-rt could radio control older versions of Yongnuo flashes also? If so I may buy some additional, previous-model YN flashes that cost less than the 600. Thanks!

    i just ordered the yn-e3 RT, just wondering does it work with ST-E3 at the same time?
    I usually use 2 cameras, both are 5D mark iii, and I have 1 ST-E3 and 1 canon 600ex-RT
    does the yongnuo work with my setup? I will have 2 master commander, 1 from canon, and 1 from yongnuo.
    (ST-E3 + YN-E3 -> Canon 600EXRT)

    any help would be appreciated

    Does the YN-E3-RT offer a recycle ready indication from the slave flashes ? The Shanny SN-E3-Rt does not.
