Why won’t a Yongnuo YN600EX-RT II sync with a YN622C-TX controller?

I bought a Yongnuo YN600EX-RT II flash and a YN622C-TX wireless flash controller to use the flash off-camera. I set the flash to wireless slave mode and matched the channel, but the controller still won’t trigger or control it. Are these two units compatible, and if not, what do I need to use the YN600EX-RT II off-camera?

Sorry, but you were given a bad recommendation. The YN622C-TX is not compatible with the YN600EX-RT II. See if you can return it, and buy the Yongnuo YN-E3-RT which is fully compatible with your YN600EX-RT II.

Yongnuo actually has three separate systems:

1) The first was a simple trigger system called RF-602, RF-603, RF-605 and was later upgraded to include remote manual power adjustment with the YN560-TX transmitter and YN560 III, IV and YN660 with built in receivers.

2) Next was the YN622 system wihich is a TTL system that is designed to operate with the YN622 receivers and the YN685 flash, but also has some limited backward compatibility with the YN560 system.

3) The YN600EX-RT is a clone of Canon's RT system and is not directly compatible with either of the first two systems.

The YN600EX-RT II and YN622C-TX are not directly compatible. They use different Yongnuo radio systems: the YN600EX-RT II uses the Canon RT-style radio protocol, while the YN622C-TX uses the YN622 TTL/HSS system.

To use the YN600EX-RT II with its built-in radio, you need an RT-compatible transmitter, such as the Yongnuo YN-E3-RT or another Canon RT-system transmitter.

If you want to keep using the YN622C-TX, the workaround is to mount the flash on a YN622-compatible receiver (such as a YN622C/YN622C II) and use the flash as if it were on-camera. In that setup, the receiver handles communication with the transmitter rather than the flash’s built-in RT radio.

In short: matching channels alone won’t help because the two devices are speaking different wireless “languages.”
