I've owned a Godox XPro transmitter before, but now I've upgraded to the newer XPro II. And it doesn't have a TCM button. The specs say it does TCM and there's a TCM C.Fn for setting the type of light I'm using. But I can't find anything in the manual about how to actually trigger TCM to convert the TTL-set power level to an M setting. What am I missing?

Godox simplified the function. Instead of holding down a TCM button for 2 seconds, all you need to do is change the mode for the Group from TTL to M (like on a Profoto Air). The basic steps are:

  1. Set a group to TTL.
  2. Take a photo.
  3. Select the Group button.
  4. Tap the Mode button to switch from TTL to M.

The power setting that was used in TTL is now a Manual power setting.

  • That's pretty cool to know. I think I'll stick with my vintage Flashpoint "R2 Pro Mark II" version that has the A-B-C-D-E group buttons around the circle/set switch at the bottom, though. Too much muscle memory to try and retrain my fingers to use the buttons up and down the upper left side.

  • On the other hand, if you want to go from TTL back to a previously set Manual power setting without using TCM, that could be a real drag that it changes the Manual power setting from where you left it the last time you used Manual power.

  • @MichaelC, Not really. The Xpro II also lets you save/load user presets for those configurations you use all the time. :)
