The first of 2 eight contact binary switch blocks used for activating various
features. The state of these switches is only read when power is first applied to
the Controller. See
for the configuration switch number descriptions
and
for the baud rates.
NOTE: Changing the state of a switch while the Controller is powered on does
not result in a change of the selected features. Switch status is only
read during the Controller’s power on sequence.
