About this task

Each controller has an EOL switch, which when set to ON, sets the controller as a terminating device on the bus. See the following figure for the EOL switch location. The default EOL switch position is Off.

Figure 1. End-of-Line switch positions

To set the EOL switch on the controller, complete the following steps:

Procedure

  1. Determine the physical location of the controller on the SA or FC bus.
  2. Determine if the controller must be set as a terminating device on the bus.
    Note: The EOL termination rules for SA buses and FC buses are different. Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for detailed information regarding EOL termination rules and EOL switch settings on SA and FC buses.
  3. If the controller is a terminating device on the FC bus, set the EOL switch to ON. If the controller is not a terminating device on the bus, set the EOL switch to Off. When a controller is connected to power with its EOL switch set to ON, the amber EOL LED on the controller cover lights up.
