EOL Termination on the Local FC Bus
The FC bus requires EOL termination at the end of each bus segment. Figure 10 shows four examples of EOL
termination on the FC bus.
Figure 10: FC Bus Segment EOL Termination Scenarios
Note: Set the EOL termination switch on a repeater’s device connection to ON only when the repeater connection
terminates a bus segment. See Scenarios 3 and 4 in Figure 10.
Note: Third-party MS/TP devices and TEC26xx Series thermostats have different EOL termination requirements
on the FC bus. See TEC26xx Series Thermostats and Third-Party MS/TP Devices for more information.
