The 1-ON-1 menu is for testing a single controller disconnected from the network. The controller of interest should first be disconnected from the network bus. For the 1-ON-1 test, the FIT should be connected to the controllers MS/TP bus of concern being either the FC bus or the SA bus. The FIT can either be plugged into the RJ-12 jack on the controller if available or wired to the FC bus or SA bus terminal block of the controller.

Note: If the controller being connected to is not disconnected from the network and is in an idle state, the connection can start the token passing on an idle network.

Use the 1-ON-1 test to verify the operation of an individual controller that may be having communication issues when connected to the network or a controller that may not be functioning properly. The FIT 1-ON-1 test communicates to the controller and provide feedback to the user pertaining to the operation of the controller.
