OVERVIEW
1.2.4. COMMUNICATIONS ARCHITECTURE
CIO units incorporate a CAN BUS port in two physical media: glass fiber optic and cable. The fiber optic port allows connection to the master unit for a single CIO unit. For connections including several CIO units, the cable port must be used. If the master unit is a F650, then communication must always be in fiber optic.
