 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”)





The YN-E3-RT transmitters are available now from around $80 –

Firmware V1.18

    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

  2. Niels Gram 5 years ago

    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!

  4. William 4 years ago

    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.


    • Fritz 4 years ago

      Hi Frank, Yes both the Yn 600EX RT flash and the YN E3 RT have a beep to indicate the flash is charged and both have an indicator light as well. The beep can be programed on or off, and the flash and the transmitter make different beep sounds. Hope this helps.

    Thanks Fritz,
    i own now the YN E3 and i was impressed how well this item works, compared to the Shanny Transmitter. Perfect in direkt sunlight, main dial works fine and no missfires.

    Hi all,

    I have the YN-E3-RT along with 2 YN600EX-RT units, I am thinking of getting a Canon 600EX-RT as well because the Yongnuo units fluff around on me a bit.

    Is the Canon 600EX-RT fully compatible with the YN-E3-RT? What functionality is lost if not?

    Many thanks!


  8. Frank 4 years ago

    Hi Matthew,
    the Yn-E3 is full compatible with the Canon 600ex-rt . I own both items. What are your problems with the Yongnuo 600ex ? I use the Canon 600ex if ETTL is needed, because results are better, especialy in HSS. The AF light is also much better if needed.

    • Matthew Gamble 4 years ago

      Thanks for the reply Frank, I find that the syncing of my flashes to the YN-E3 is a bit dodgy sometimes and will require me to cycle through the modes to get the green light to come back on, also I dropped one of them a few months ago onto carpet and it plays up pretty much every shoot now, if it gets a slight tap against the other flash it resets – I understand that they are cheap and this may to be expected, but I find that more of my time is being consumed with the flashes messing around on me now.

      I also find that the YN600’s arnt that bright, I photograph property, and I pretty much need both of them just to light one room, if I do a remote setup and have one in another room the light given out by the single unit in my hand is not enough. Perhaps the cheaper bulbs burn out quicker not sure.

      Thats good news that the remote ETTL works with the YN-E3 and Canon 600ex-rt, that is a big part of my normal working system.

    Is anyone using the YNE3-RT receiver with a Canon legacy 580EXII and Canon 600 EX-RT with a Canon 5DMII and the YN-E3-RT and are able to control groups, in manual, ETTL and HSS? If so, would I just need one receiver with this setup, or two (one for the Canon 600 EX-RT too?)

    Also, I ALWAYS use both speedlite’s off camera on light stands, never a flash in the Canon 5DMII hot shoe.

    If you are using a setup like this please let me know. The Canon 5DMII has been the hiccup in my process so far since it’s a pre-2012 DSLR.

    Thank you!

      Hi Julia,

      In don’t have a 5DII, though its likely the most common camera used with the YN-E3-RT and Canon 600EX-RT flashes, so you should be fine.

      Yes you should be able to control groups in Manual, ETTL, and HSS, with both flashes.

      And you only need the one receiver unit for the 580EXII.

      The Canon 600EX-RT has the radio receiver built inside.


      If you’re after more slave speedlites down the track you may like to try the YongNuo YN600EX-RT (from around $100). They have the receiver built inside as well.

    Is the YongNuo YN-E3-RT compatible with the YN 968 speedlight?

    • Author

      Hi Teto,

      The YN-E3-RT is directly compatible with the YN-968EX-RT, but not the YN-968N (for Nikon).

      EDIT – Sorry I also just saw your previous questions in the YN-968EX-RT comments. Yes the Canon 600D should be compatible with the YN-968EX-RT.

      The YN-622C radio triggers are not directly compatible though. You could still use them if attaching a YN-622C as receiver to the flash though.

      If you prefer the YN-622C radio system, then a flash like the YN-685 C is directly compatible with the YN-622C.
