Factory Reset of CU3-01M & CU3-02M

Factory Reset Procedure (CU3-01M & CU3-02M)

1. Power Cycle the CU

   • Turn off the CU (remove power briefly).

   • Prepare to press the buttons before powering it back on.

2. Initiate Factory Reset During Power-Up

   • As you power the CU back on, immediately press and hold three buttons together: UP + RIGHT + LEFT

   • Continue holding until the display shows the menu. And from menu choose the Factory Reset option.

3. Confirm Factory Reset

   • The display will prompt you to confirm the reset — follow the on-screen instructions.

   • Once confirmed, the CU will begin resetting itself.

4. During Reset, Connect iDM for Firmware Update

   • While the reset process is running, Display shows connect to iDM.

   • Connect the CU to your PC via LAN.

   • Make sure your PC and CU are directly connected using a network cable.

   • Open iDM and connect to CU using default IP and CU addresss.

Default IP and Network Setup After Reset

• After reset completes, the CU will revert to default network settings: ➤ CU IP: 192.168.1.1

• Set your PC’s LAN adapter to a compatible IP in the same subnet, e.g.: ➤ PC IP: 192.168.1.10 ➤ Subnet Mask: 255.255.255.0

Connect iDM3 to CU

• Open iDM3 on your PC.

• Connect to the CU using: IP: 192.168.1.1 CU Address (default — check label/project if changed)

1. Update Firmware

• Use iDM3 to perform a firmware update while the CU is in reset state.

• This ensures the unit boots with the correct firmware after reset.

Important Points

Factory reset clears all configuration and project settings in the CU. After reset, the CU’s IP is 192.168.1.1 and must be reachable from your PC. Network must be set manually on your PC to match the CU IP range for iDM3 to connect. Always update firmware immediately after reset to ensure proper system behavior.
