There is one unique number which identifies each possible combination of on/off settings at the
DIP switch. While the industry configuration (switch 1 through switch 4) is readily available
from the Software version mode (described in 4.1.2: Determining the Software Version, page 62
), the settings of other switch positions are only apparent from this display or by looking at the
processor board.
