The Commander Site Controller's backplane board functions as what?

The Commander Site Controller's backplane board serves as the foundation for all other boards within the system. This foundational function is critical because it establishes the support structure necessary for the interconnections and communication pathways between the various components of the controller. Essentially, it acts as the backbone of the system, ensuring that all other boards, such as processing units and communication interfaces, can connect and operate effectively. The backplane board allows the exchange of data and power throughout the system, which is vital for the overall functionality and integration of the Commander Site Controller.
