Beside some used channels to control gimbal movements, there are 3 free channels that you can use to trigger your camera by the SYNC. You can check them in AUX menu.
Now select a channel to explore its setting. For example, select channel 6 setting. The following is brief explanation about channel’s parameters, all of them can be adjust by using the navigate button under the LCD display.
- Reverse: press left/right to change the direction for channel’s response (Normal/Reversed)
- Trim: press left/right to adjust the value. It likes TRIM on your RC.
- Limit Left & Limit Right: they are something like the endpoints for each channel on your RC
- Exit: back to the AUX menu
The things above just described about the setting for each channel. Now, how do you use it?
In the photo above, the first item of this list is Control. When you select it, you should be navigated to the screen where the signal value of the channel will be displayed.
You can navigate left/right to switch to other channel, in the above photo, it is channel 6.
By using Up/Down stick, you can control this channel, the same way with what you do on the RC stick. And when you press and hold the center button, it will return to zero.
