Operating Instructions
Online Read & Write Operations (PC Connected)
When connected to a computer, the device functions as a multi-card reader, allowing independent access to each CFast card.
- Ensure the device is powered on and connected to your computer via the USB cable.
- Insert CFast cards into any of the available slots (Source 0, Target 1-5).
- Your computer's operating system (Windows, macOS, Linux) will detect the inserted cards as separate drives.
- You can now read from or write to the CFast cards as you would with any external storage device.


Offline Cloning Process (Standalone Operation)
The device supports 1-to-5 offline cloning without requiring a computer.
- Prepare Cards: Ensure the source CFast card (the card you want to copy from) is inserted into the Source 0 slot. Insert up to five destination CFast cards (the cards you want to copy to) into the Target 1 through Target 5 slots.
- Capacity Requirement: Each target card must have equal or greater physical storage capacity than the source card.
- Power On: Ensure the device is powered on.
- Initiate Cloning: Press and hold the Clone button for approximately 3-5 seconds until the cloning process begins. The progress display will show the cloning percentage, and the target card slot lights will blink rapidly.
- Completion: The cloning process is complete when the progress display shows 100% and the indicator lights for the target cards stop blinking.
- Safe Removal: Once cloning is complete, power off the device before removing the CFast cards.
