The Remote Field Bus requires EOL termination at the end of each bus segment. Figure 1 shows four examples of EOL termination on the remote FC bus.

Figure 1. Remote Field 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 1.
  • Third-party MS/TP devices and TEC26xx Series thermostats have different EOL termination requirements on the Remote Field Bus. See TEC26xx series thermostats and third-party MS/TP devices for more information.
