The Status Command Center (SCC) is used to annunciate and/or control monitor and control points. Its controller
board has a switch package (S2) which is used to address the controller and determine if LEDs are to illuminate
during power failure. There is also a switch package (J6), which is used to select the baud rate; a WRITE jumper,
used for programming; and a reset switch (Sl).
The first 6 switches of switch package S2 are used to address the SCC as follows:

switches.
