Figure 10 Connecting Multiple Drives to a BACnet Workstation – System Overview
The two ends of the BACnet network must be terminated with a 120 ohm resistor between
the “+” and “-” and signals. The SI-B3 has a built in termination resistor that can be enabled
or disabled using DIP switch S1. If a drive is located at the end of a network line, enable the
termination resistor by setting DIP switch S1 to the ON position. Disable the termination
resistor on all slaves that are not located at the end of the network line by setting DIP switch
S1 to the OFF position (The factory setting for DIP switch S1 is OFF).
