Godox Flash Guide
Channel and ID
Before you start handling flashes and transmitters, let’s choose the channel and ID that the transmitter and flash will use to communicate.
Choose a Channel
Most Godox flashes and transmitters can communicate over 32 available channels, numbered from 1-32. Some older models can only use 16 channels, they are now discontinued.
So, choosing a channel is only a matter of choosing the number for it. I recommend avoiding channel 1 because it’s the default channel and many people use it.
For this guide, I’ll use channel 9. Why? I just like it. You can select any of the 32 channels available.
Choose a channel number and write it down.
Choose an ID Number
ID is an optional function you can use to avoid interference from other Godox flashes, in case they are set to the same channel. However, some flashes like the TT600 or V850II don’t have this feature.
If you use a flash that can’t set an ID in your setup, none of the flashes in your setup will be able to use the ID function. In this case, make sure it’s Off.
Choosing an ID is a matter of choosing if you’re going to use it and, if so, what is the number you’ll use as ID. There are 99 ID numbers to choose from. I set mine to 18, just because I like it.
Choose an ID number or choose to set it to Off and write it down.
Manual or Remote Zoom
If you use hotshoe flashes in your OCF setup, you can set the zoom for each flash or you can control the flash zoom from the transmitter.
Many transmitters allow you to set different zoom values to each group. However, some others, like the X1T and X3, set the zoom value for all groups in your setup.
Choose the zoom value for each group in your setup and write it down.
