1-ON-1 Menu
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.
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.
