(There are no limits on the branching format or main, branch, or total line
lengths. The terminator must be connected to the point in the system farthest
from the master.)

*1. A terminator must be connected to the point in the system farthest from the Master.
*2. The baud rate is switched using DM settings (default setting is 750 kbps).
