Does a brand new Ruby2 have a register number or static IP address set?

A brand new Ruby2 typically does not come with a pre-set register number or static IP address. These parameters must usually be configured during the setup process to match the specific requirements of the retail environment. Originally, the device may have default settings, but they are not static; the user or the system administrator is responsible for configuring them based on their needs.

Therefore, the correct answer emphasizes the need for configuration rather than the device coming pre-equipped with these identifiers. This aligns with common practices in retail environments where devices are tailored to work within specific network infrastructures. The emphasis on user configuration underscores the importance of understanding the setup requirements for operational efficiency in a retail setting.
