EOL Termination on the SA Bus
On an SA bus, the minimum requirement is that EOL termination must be enabled on at least one device. Since an
SA bus supervisor always has EOL termination enabled, this requirement is always met; however, for enhanced
bus performance, we recommend that you enable EOL termination on the devices at each end of the SA bus. See
Figure 11 for SA bus EOL termination scenarios.

Note: The MS-BACEOL-0 RS485 End-of-Line Terminator module is not designed for EOL termination on the SA
bus.
