COMM Bus
Main Modules communicate with each other using the COMM Bus to form an integrated system. Each Main
Module has two COMM Connectors: COMM In and COMM Out. The COMM Bus is wired by connecting the
COMM Out of the first module to the COMM IN of the second. The COMM Out of the second module is
connected to the COMM In of the third and so on, until finally the COMM Out of the last module is connected
back to the COMM In of the first module to complete the COMM Bus. If there is only one Main Module in the
system, the COMM Out of that module is connected to its own COMM In (see Figures 7 to 9).
