TROUBLESHOOTING

1. gTune Displays “DISCONNECTED”

Issue: gTune software shows “DISCONNECTED” even after connecting the gimbal via USB.

Solution:

• Check Device Manager to confirm if Silicon Labs CP210x USB to UART Bridge (e.g., COM3) is recognized.

• Make sure the gimbal's mode switch is turned to “G” (gimbal) position.

• Ignore the gimbal's operational status (e.g., LEDs or movement).

• Then, proceed with the normal firmware upgrade process in gTune.

2. Strong Vibration During Operation

Issue: Gimbal exhibits strong vibration after startup or during movement.

Solution:

• Import the correct gimbal profile for the corresponding lens using gTune.

• If vibration persists:

  • Gradually reduce the Stiffness values by 5 units at a time until vibration decreases or stops.
