The recent firmware update for the FUJIFILM X Series and GFX series (X-H2, X-H2S, GFX100 II) allows these cameras to now accept timecode via their USB-C port.
For Ambient Lockit and NanoLockit users, there is no firmware update needed as the Lockit boxes already support USB-HID output. You also don’t need a special cable as a regular USB-C to USB-C cable (for the Lockit) or a Micro USB to USB-C cable (for the NanoLockit) will work.
You can also use this USB interface for MIDI Timecode (MTC) applications on your computer, for example, when you are working with a DAW for music videos (see FAQ article on MIDI Timecode).
