Note 1: On MV4, the front port can not be used while the rear port is in use. On the MV5, there are 2 separate serial
ports so both may be utilized simultaneously. (i.e. FCA module permanently connected on rear while allowing local
access via the front port).
Note 2: This design solves the multiple FOCUS masters in an APM system when one or more loops are broken. This
solution can only work in an MV4 and MV5 FOCUS network because of their ability to sync. in all directions.
