- Your PC is now ready to start the programming. Before we can start, we need to establish a connection to the T1 controller that is part of the VSD-box.
- Connect the USB-Nano cable end to the X07 terminal of the T1 controller as per the screenshot below.

- Verify that the wire of the USB-Nano device which is labeled with the letter 'A' is connected to 'L1' and letter 'B' is connected to 'L2'.
- We are now ready to start programming! Click the 'flash' icon
on the FlashTool software to initiate the programming.
- If the VSD-box (and T1 controller) are turned off, apply the power supply to start programming.
- If the VSD-box is already powered on, please remove the power and re-apply it (perform a power cycle).
- You should see the following:

- When the flash programming process is successfully complete the controller will automatically reset, the new application software will run.
- Remove the USB-Nano connection to the T1 controller, and re-connect any previous disconnected terminals / cables / wires.
- Verify all parameters and readjust if required.
TROUBLESHOOTING
- The computer and T1 controller have not been able to connect. Verify the hardware connections made between the USB-Nano and the controller.
- Be sure to perform a power cycle while attempting to initiate the programming.
- A COM port has been selected where no USB-Nano tool has been detected. Reverify the selected COM-port.
