True or False: The VEX Cortex should be powered OFF when connected to a computer.

The statement is true because when connecting the VEX Cortex to a computer, it is important to ensure that the device is powered off. This is primarily to prevent any potential issues or damage that can arise from improper power states during data transfer or updates. When the cortex is powered on, it may interfere with the communication between the computer and the Cortex or result in an unstable connection.

In addition, powering down the Cortex ensures that no unintended operations occur while configuring the settings or performing firmware updates, which helps preserve the integrity of both the device and the data being handled. By following this guideline, users can maintain the functionality and reliability of their robotics systems.

Other options, such as suggesting that it should be powered on only during firmware updates or when changing settings, may overlook the potential risks associated with those actions if done while the Cortex is powered. Maintaining a powered-off state when connecting to a computer is a best practice for ensuring smooth communication and operation.
