GODOX – X1-C – TTL Triggers for Canon – Now Available




Godox have released details on their soon to be available X1-C, TTL and HSS enabled 2.4GHz radio trigger system for Canon DSLRs.

The X1-C will be Godox’s first TTL enabled radio triggers available, and they will be released alongside the new TT685C Speedlite, with compatible radio transceiver built inside.

UPDATE – Nikon version X1-N, and Sony version X1-S are also now Available.


UPDATE - Godox have added a static Page Mode interface option, which stops the groups from moving around on the transmitters LCD screen. To Enter this mode hold down the CH Channel button for 5 seconds

There are more details on this Page Mode at the bottom of the post under the Custom Functions list.




The X1-C are separate transmitter and receiver units, with X1-C receivers being compatible with MK II style Canon compatible speedlites like the 580EX II and 600EX-RT etc.

As well as Canon ETTL compatible flashes like Godox’s own V860C.




As well as the traditional Canon A:B C ratio style interface, the X1-C provide a full GR Group style interface allowing up to 5 Groups to be individually set to either TTL, Manual, or Off.

So most importantly TTL and Manual Groups can be conveniently mixed together as needed.

PLEASE NOTE – GR Group mode requires camera models from 2012 onward.




The X1-C provide TTL, HSS (High Speed Sync) and most of the features comparable popular TTL triggers provide, even a HSS Pre-sync Timing Adjustment.

Godox have even considered small (though important) details like PC Sync Input and Output, something most radio triggers constantly miss.

UPDATE – Second Curtain Sync has been added to the X1-C transmitter from firmware version V09 onward. (Set Custom  Function 04 to 01 to engage).

X1-C receivers provide a simple Channel and Group selection interface.




The X1-C receivers 2.5mm Sync Port output can be used for wired and wireless shutter release, as well as firing studio strobes.





The X1-C will be Godox’s first TTL enabled radio triggers available, and they will be released alongside the new TT685C Speedlite, with compatible TTL radio transceiver built inside.The TT685C Speedlites provide both Radio Master and Slave modes.

V860C Speedlites can be fired and controlled off camera while being attached to X1 receivers. And even current Manual Godox Witstro (with X1-C receiver attached) can now be fired off camera with no extra transmitter units attached to the camera.

The Godox PB960 external high voltage battery packs providing a very fast recycle option with the TT685C Speedlites, on or off camera.










C.Fn-00 – Synchronization Delay Setting – [ 00 = OFF ] [ 1-100 US delay setting ]

C.Fn-01 – Single Contact Mode – [ – –  = OFF ] [ on = ON ] (stops transmitter going to sleep)

C.Fn-02 – Zoom Setting – [ – –  = No changes ] [ AU = Changes with lens ] [ 20, 24, 28, 35, 50, 70, 80, 105… ]

C.Fn-03 – PC Sync Socket – [ In = PC Sync connect with Camera ] [ ou = PC Sync connects with Flash ]

C.Fn-04 – Rear Curtain Sync – [ – –  = OFF ] [ 1 = ON ] (camera shutter must be between 30s – 1/30s)

C.Fn-05 – Enable 1/256 Power Level – [ 1/128 = OFF ] [ 1/128- = ON ]  (1/256 is displayed as 1/128-)

C.Fn-06 – Switch between 3 and 5 groups in GR Group Mode – [ 03 = 3 groups ] [ 05 = 5 groups ]

C.Fn-07 – Turn remote flash beep Off / On – [ – –  = OFF ] [ on = ON ]



A function to remotely turn the modelling light On and Off on strobes like the AD600B has also been added to the X1 transmitters.

Double pressing the Channel button will turn the modelling light ON or OFF.




After some persuasion, and the help or Adorama / Flashpoint, Godox have implemented a static Page Mode interface option, which stops the groups from moving around on the transmitters LCD screen.

To engage the Page Mode interface hold the Channel button for 5 seconds, or until the groups show again on the LCD screen (after the custom functions disappear).

A flashing Group letter now indicates the current Group selected.

– Single press the Group button – To scroll down groups.
– Double press the Group button – To scroll up groups.
– Turn the Dial – To adjust the Group setting.
– Press the Channel button – To lock in the setting (will also lock in automatically after 2 seconds)


(Unfortunately this is still not quite as we suggested, which would be using the dial to quickly select groups. Though at least the groups are not constantly scrolling around on the LCD screen now).

Godox have also implemented Custom Function C.Fn-06, which allows the display of just 3 groups when you’re currently not using all 5.

This makes it faster to scroll through (by continually pressing the Group button) just 3 groups all displayed on the one page, to select the group you’re after.





The Godox X1-C TTL triggers for Canon are available now from around $80 a set of Tx & Rx –

    Hey guys,

    I recently purchased a Godox c1c transmitter and receiver. It has the most recent firmware so i assume the ones i got is the currnt production. No sliding hot shoe. However i have an issue with its hss (high-speed sync). This is the combination:
    I have an outdated 450d (yeah, but still shoots fine)
    I use it with triopo tr-982ii (hss,ettl etc)
    The default firmware of the reciever was ver16. Due to this, i wasnt able to use the M mode. What i did to solve the problem was update it with ver17 and it fires the M mode. Also, worth noting that gr mode doesnt work with 450d.
    Now heres my problem:
    I cant make HSS work even though the TR-982ii has built in hss. I’ve tried setting the flash on hss but no luck, goes back to non-hss.
    Now my question is this, is it a flash issue or x1 issue that doesnt allow me to use hss?

    Any news about X1c firmware update for setting off Group with XTR16/s ?

    • nixland 3 months ago

      Where is Elv ??

  5. Richard 3 months ago

    Hey, can you confirm whether or not the X1T-C transmitter can double as a receiver? Can I use one X1-C to trigger another one without using the separate X1-R receiver?


  6. Jules 3 months ago


    I got a problem if anyone can help please.

    Camera is 5D3 (with X1T) and ex430ii (with X1R). The flash itself will only operate in TTL mode regardless of any setting on the X1T. I can’t get the ex430ii to stay in manual mode. Both are on firmware v15. Any ideas what’s wrong??

    It all works fine with my pair of TT600 and in TTL on the Canon flash. But cannot get the Canon flash to operate in manual mode. :(

    Any news about X1T Canon firmware update for setting off Group with XTR16/s ?

    Does the X1 trigger work with the new Ving 850?

      Hi Bryan,

      Yes, if you mean the V850II.

      The original V850 would require clip on 2.4GHz XTR16s receiver to be compatible with the X1 transmitter.

    i have an issue with my canon flash ex 430II and godox tt600 , when i place on the hotshoe the canon flash in X1c doesn’t work pass thru am i doing something wrong ?
    example: i set the TT600 and the X1 same group & channel when i change value to TT600 Thru the X1 the canon flash in the hot shoe it turns from TTL to manual…

    if anyone can help.

    Did anybody successfully fire a flash with the Godox X1T-C and the Canon eos M3? My Godox TT685 & the X1R ignores manual and TTL mode.

    • Jesse Patterson 3 weeks ago

      Not me. The M3 has always had issues with third party flashes and triggers. I hope Godox comes out with a firmware update for both the M3 & M5 since I also use speedlites with those cameras.

    Hi, i have the old FT 16s receiver for my v850 and v860C if i buy only the X1 transmitter (or transceiver whatever you call it) i could control my flashes like the ft16 transmitter? for the HSS for me doesnt matter because i have CELLS II for HSS. I only want that X1 godox for the AF Light dont need TTL or HSS i just want control the flashes (power controls on – off and these things) Hope you can solve my doubt
