Updating Firmware -


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.

Download links for Driver / Updater Software at the bottom of the page here -

The update software is currently for Windows only.

You need to download both of the links – “Driver & Software:” and “Firmware v1.0X:

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

Firmware upgrade instructions:

1. When you prepare to upgrade YN-E3-RT first time, please download the driver and software package, uncompress it and run YN_Trigger_Updater_Setup.exe to install the driver/software.

2. Download the most update firmware package and unzip it.

3. Turn off YN-E3-RT, keep pressing mode button and turn on it again. The screen will show “YN-E3-RT Firmware Upgrade”. Connect the device to your PC via a USB cable.

4. Run YN_Trigger_Updater from start menu. Click on “Browse…” Button and navigate to the firmware you download in step 2. Wait a few seconds until the device is detected. Click on “Update” to begin. When is done, YN-E3-RT will be reset automatically and you can use the new version now.

5. If any error is encountered when updating, please turn off YN-E3-RT and try again from step 3.


Previous Firmware Versions -

Version 1.10:

Fixed: couldn’t set fec of group b/d via camera menu.

Version 1.09:

Fixed: update limit of flash number in Multi mode.

Fixed: disable HSS in multi mode

Added: P.FN: legacy trigger mode. When it’s set, YN-E3-RT won’t detect ettl
input so that it can be used on Fuji hotshoes.

Added: P.FN: Free Mask Group. This setting is used with GR/*. Free mask will
be on/off when you hold GR/* button for a few seconds. When Free mask is on,
groups not in this setting won’t fire. So you can take a photo with background
flashes only quickly.

Version 1.08:

Fixed: correct ettl2/gr exposure for 1D-X.

Fixed: improved light metering for cameras after 2012.

Version 1.07 -

Fixed: When one of the group is set to ETTL mode, if one of the flash is not
recycled, it may make a full output flash due to incorrect light metering. Now
YN-E3-RT won’t trigger a flash in such a situation. Note: if the group is set
to M mode, a flash will be triggered no matter it is recycled or not.

Fixed: improved flash syncing with cameras after 2012.

Added: Legacy flash trigger (for non canon cameras). Now you can use YN-E3-RT
on non canon cameras with standard iso hot shoe. You need to press test the
test button to transfer the M mode parameters.

V.1.06 -

Added: allows the firmware version to be checked in menu 4.

V.1.05 -

Added: compatibility with 5D MKIII and 6D cameras.

YongNuo YN-E3-RT

Until the YongNuo flash arrives, the original Canon 600EX-RT would currently need to be used with the YN-E3-RT transmitter.

There has been no indication as yet of when the YN-600EX-RT flash will be available.

 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 -

There is also currently no word on whether separate receivers will be available later to accommodate other current and previous Canon or YongNuo TTL flashes, or manual studio lights etc. UPDATE – YongNuo have now mentioned a studio light solution is also coming. Though it is still unknown as yet if that will include separate receivers or not.


Price and Availability -


The YN-E3-RT transmitter is now available now from around $140 on Amazon,

    I would like to know if you put a yn-e3-rt on top of a Yn622c work, why I want to do this? so I can trigger my two 600ex-rt with the Yn-e3-rt and trigger my two strobes with the Yn622c at the same time, any idea? I have already the Yn-er-rt which work very good with my 6D.
    I can trigger the strobes already if I set them as slave but if I need to go over 1/125, I already have the

    • Flash Havoc says:

      Hi Mel,

      You definitely can’t run both units as TTL transmitters at the same time, as they are both trying to communicate with the camera at the same time.

      But the YN-E3-RT has a remote manual compatibility mode, so if you only want basic firing, and remote manual power control with the 600EX-RT, then you could likely stack the YN-E3-RT on top of the YN-622C in this mode. (Or worst case scenario would be to cover the TTL contact pins between them).

      But at the end of the day, the best option would be to just use extra YN-622C receivers on the 600EX-RT as well. And when the YN-622C-TX is available, use that as the transmitter for all the flashes.

      It’s a shame to have to use YN-622C on the 600EX-RT when they have their own radio, but its going to be a lot more practical and functional. Otherwise it would best to move on to all RT gear. Maybe trade your old non RT flashes for YN-600EX-RT when they are available.

      The YN-622C-TX should be a good alternative though, and relatively inexpensive for one of those and a pair of YN-622C.

  2. Cameron says:

    Here is my situation. I have a Canon St-E3-Rt and now a Yongnuo YN-E3-Rt. I would like to use both at the same time and fire my 2 600′s. One on each hip (5Diii & 6D) They both work great by themselves and control both 600′s fine. When both are turned on one goes green and the other goes orange. When I turn off the green one the other turns from orange to green. Whichever is on 1st gets the green light.

    If you read the YN manual it says “Multi YN-E3-RT can share slave flashes”

    Am I reading this correctly? Can I have multiple commanders and control several slave flashes?

    I also cannot get the AF assist light to fire on my YN-E3-RT, anyone else have this issue?

  3. privatebydesign says:


    Yes that is correct, it is all working as it should, you can have multiple “Masters” the first is the “Main Master” the rest, and there can be more than two, is a “Sub-Master”.

    Any of the masters has complete control of any and all flashes and the settings can be completely different, even the modes and groups.

  4. Nick says:

    I use the yongnuo yn-560 ii and I am looking for a way to remotely change the power settings. Does the YN-E3-RT do this and is it compatible with the yn-560′s?



    • Flash Havoc says:

      Hi Nick,

      Unfortunately no, there is no way to remotely change the power setting with the YN-560 II, as that function was never built into the flash.

      The YN-560 III does have a remote manual power control built in, but we are still waiting on the dedicated transmitter unit which will enable that.

      The only remote manual option currently available with a transmitter are the Godox V850 (and they are great flashes).

      • Nick says:

        Thank you for the response… I have been researching a little and was wondering if I can accomplish changing power setting remotely using the YongNuo YN-E3-RT and Yongnuo YN-565 EX.

        If you have a better solution that would great.. When I need to change power setting on any of my flashes I have to open up the soft box and change it manually… I am trying to eliminate this… Would like to accomplish this is the cheapest way



        • Flash Havoc says:

          Hi Nick,

          Sorry no the YN-E3-RT are only compatible with the Canon RT gear, and the coming YN-600EX-RT flash.

          The cheapest way will be the YN-560 III flash and the new dedicated transmitter (though we don’t know when that will actually arrive).

          But for a little more than that you can get the Godox V850 flashes and FT-16 transmitter, which are available now (and arguably a much better option anyway).

          • Nick says:

            I took your advise and got the Godox V850 you suggested and I love the flashes and the transmitter receiver combo… Great product so thank you …. One question I do have is do I need to get a different transmitter to take advantage of High Speed Sync?

            Thanks for all the help,


            • Flash Havoc says:

              Hi Nick,

              Ok great, thanks. Yes for HSS with Canon the simplest way would be a Godox Cells II transmitter.

              You can see some other options here as well. Though the Cells II are a good option if you don’t need to trigger other TTL flashes etc. Thanks.

  6. Joe says:

    Quick question if anyone can please help. I want to buy one of these but need to know if it does HSS with the canon 6d! I know the canon version only allows HSS with the 5dmk3 and the 1d, no HSS is a deal breaker for me using the 6d and being stuck at 1/180th. Thanks again

    • Flash Havoc says:

      Hi Joe,

      Yes the YN-E3-RT will work with HSS with the 6D.

      Are you sure the Canon ST-E3-RT will not work with the 6D in HSS? I have not heard about that issue? Thanks.

  7. zak says:

    will this enable high speed sync between my 600ex-rt and my 7d? is there anything that works differently (or not at all) than when my flash is on camera? this looks like it might be a better option for me than the ST-E3-RT.


    • Flash Havoc says:

      Hi Zak,

      Yes it should work with the 7D with HSS.

      I think most functions should be the same as on camera, though Second Curtain Sync is only available in manual with the YN-E3-RT. Thanks.

  8. zaakir says:

    Having consistency issues with the 7D in ettl. first couple shots are fine, then either a full flash dump, or a misfire all together. In manual mode there is no issue, so there’s obviously a communication problem with the ettl metering.

    Seems to work fine with my 5D3, anyone else having issues with the 7D?

    I’m still on 1.08 as far as firmware.

    • Flash Havoc says:

      Hi zaakir,

      I’m not sure about any specific issues with the 7D. It may just be more of an issue with your 7D hotshoe being a little different.

      If you haven’t already done it, try cleaning the hotshoe contacts with some Isopropyl alcohol or similar.

      There is so much movement in the YN-E3-RT foot in the cameras hotshoe, and then the pins move around in the YN-E3-RT foot as well. So it doesn’t surprise me some people are going to experience issues.

      I really hope YN do something better with the coming YN-600EX-RT Flash foot.

  9. zaakir says:

    OK so after cleaning the contacts and extensive testing, I’ve determind there’s an issue with the/my 7D.

    The trigger works flawlessly with my 5D3, and even my mirrorless EOS-M. On the 7D however, it misfires. It even does it when you hit the FEL button. I didnt get full power dumps this time, but a number of misfires.

    I then decided to use a 600ex on the 7D as a trigger for my other 600ex, and viola, no issues what so ever. So apparently there’s a communication issue somewhere. Perhaps upgrading the trigger to 1.10 would help.

    further testing needed…

    Anyone have an issue with windows 8 not seeing it? I installed the software and have the latest firmware, but it does not see the yn=e3=rt
