Communication Cable Topology
The dual communication cable ports on the option board act as a switch to allow for
flexibility in cabling topology.
Users may employ a traditional star network topology using a single communication
cable port on the option.
Users may also choose to employ a ring topology using both communication cable
ports on the option and reduce the requirements of MECHATROLINK-III hub
module ports.
