Thumbwheel
Switches
The thumbwheel switches on the front of the NCC 2020 module are
provided as a measure of last resort for configuring the NCC,
and/or application modules it controls, when terminal access to
the Craft interface is not possible.
It is preferred practice to use the Craft interface, Access Manager
2000 or Node Manager instead of the thumbwheels.
For a detailed procedure see “Thumbwheel Procedure” in
Chapter 3.
