NOTE: VBUS is an internal communication bus that related VBUS modules
are used with. The VBUS is not intended for external use. It has been
designed to be used in a protected enclosure with adjoining interconnection
between modules in the same enclosure. It communicates with the main
control over the Module Bus (SNAPP) which is for external communications.
