2.4.2 Star Connections
Star connections allow you to connect slave stations through Hub Modules that are connected
to the MECHATROLINK-III communications port (CN6) on the MP3000. In this topology, each
port on the Hub Module connects to one slave station.
1. Do not connect more than 19 stations up to the final slave stations to any one CPU Unit port.
2. The maximum number of stations that you can connect with cascade connections depends
on the transmission cycle. Refer to the following section for details.

1. Terminating resistors are not required at the SERVOPACKs.
