Management Level (Choice Field) Repeater / Unit / Port
Toggle to the level you wish to manage.
Unit ID (Text Field) Enter the identifying number of the unit you wish
to manage. The Unit ID is a digit, and is displayed by the Unit LED on
the front of each unit.
The unit with the Module installed is unit 1, the next unit in the stack is
unit 2, and so on.
If the number entered into the Unit ID field is invalid (that is, the unit is
not in the stack), the button choice will be rejected. The same will
happen if the Module cannot communicate with a unit whose Unit ID
is known to be valid. In this latter case, check the cable connections.
Port ID (Text Field) Enter the identifying number of the port you wish
to manage.
